View Full Version : Gripe of the day - What is yours?
well, the battery arrived and...
...it doesn't work. :(
It won't power up the laptop, when the charger is plugged in it says it has 88% charge but the charger doesn't get warm and never changes from 88%. If they've followed the same colour code on their battery as Lenovo then they have the wires crossed. I'd need to cut the wires and cross connect them to fix it since the pins aren't removable from the mini plug and since I don't know what the pin out is anyway, it would be a gamble so I'm a bit stuck.
I'm sure this is why China's GDP is so high - you have to order two to get one that works.
Apparently being wired differently with the same colour wires in different places isn't a problem. They suggested leaving it on the charger for 24 hours but since the charge level didn't change in 4 hours and the charger was cold I didn't think it worthwhile. Then they asked me if the battery (that they recommended) is the same as the original. Since it's a 3 cell instead of a 2 cell running at a different voltage with a different firmware level and a higher capacity I'd have to say: no. So now they want me to buy a new charger. I declined and asked for an RMA - it's gone quiet.
Shouldn't replacing a battery be simple?

Since when did a bayonet fitting become old fashioned? Went into B&Q (yes I know) yesterday looking for some LED bulbs, and couldn't find any of the right lumens with a bayonet fitting.
My girlfriend went and asked a young assistant, who instead of saying I don't know, said it was probably an old fashioned fitting!
Sparky had just put in new bayonet light fittings!

its another euro thing and was to make buying bulbs universal.
higher power LED (over 80w equivalent) are very few and far between and cost a a lot of money.

well, there's the Edison thread (standard USA bulb), the small Edison thread, the bayonet cap (what we used to think of as normal), the small bayonet cap, the GU10 (early type LED and halogen) and a few obscure ones, too
When I left for US in 89 it was bayonet cap only, when I came back you'd changed everything. I can't leave you alone for 5 minutes. :rolleyes:
I've a huge box of spare light bulbs, with every conceivable fitting, wattage, technology and now colour temperature. Despite that when a bulb blows in this house I've never got the right replacement.

My nieces new house had the 'GU10' base fitted in every fitting, I fink it is an elf and safety thing, when the bulb is out there are no exposed electrical contacts for people to poke fingers ( or their tongue ) into.......

people not being able to grasp the concept that there is no ''Ground'' in a DC circuit. its either Positive or Negative... this includes vehicle wiring.
...its either Positive or Negative...
Relative to what?
Unless you do want a truly floatng DC system, then it's fairly common practice to 'ground' one side of the DC supply (i.e. connect it to earth, widely accepted as "Ground" reference point, 0V.)
I do accept that vehicle wiring systems are not truly 'grounded'.

23-05-21, 02:11 PM
Rain. It's just bloomin' dismal. Gonna start building an ark.
0V is not a ground. its the state between positive and negative cycles where there is no voltage. if there were ever to be a DC ''Ground'' this would be it. but because it only happens between each cycle then its not a permanent thing.
modern vehicle wiring so called ''Ground'' is actually a common negative and usually the frame/chassis.
if DC only has Positive and Negative then where is this magical 'Ground'' people speak of... what they should say is Common (COM).
Earth is something completely different and in this country its called Protective Earth or PE for short and is part of the AC mains but usually connected to a stake in the 'earth/dirt' dependant from the incoming Live and Neutral..
problem arises when other country's refer to earth and ground as the same thing.
the term ''ground'' is why a lot of people get confused with vehicle wiring. when people grasp the idea that all wiring is ''live'' until it connects to negative either by the frame/chassis/battery terminal they understand better.
lets take the so called ''ground'' wire that a headlamp bulb has coming out of the other side to the Positive feed. if you cut the ''ground'' wire and insert another bulb in-line then that new bulb will illuminate when the lights are turned on... therefore its not ''ground''. you can also do the same by 'tapping' into the so called ground wire and connecting the other end of the bulb to the frame which is connected to negative.
the frame/chassis of a vehicle is just an extension of the negative terminal of the battery.
yes its a pet hate of mine.. ROFL

Got soaked in Brighton yesterday visiting The Monkey. We took out hire bikes (same sort of scheme as Boris Bikes in London) and cycled the two miles to the Marina for lunch. We had to stop under the awning of a shop when the light drizzle turned into full on tropical deluge. It stopped when we got there and of course poured down again as soon as we set off back after the very nice pizza...

Perhaps we share two gripes? That (i) terminology is often inaccurate and misleading, and (ii) people don't understand electrical systems as well as we'd like. :smt102
"Ground" and "Earth" are often used interchangeably (and I accept wrongly in some cases) because the origins of the terms date back to systems being literally 'grounded' by electrically connecting part of it to the ground of Planet Earth. AC or DC system, the 'grounding' principle is the same. I agree that 'Common' is a better term for a lot of applications.
On terminology, a DC source really only has a high potential and a low potential terminal. Neither is technically fixed as 'positive' or 'negative' and both can be dangerous unless a stable reference point is established. This is usually done by convention against the ground we stand on, earth potential that is usually taken as 0V (though it's not always as simple as that*)
(As I'm sure Bibio knows, but for the benefit of future knowledge searchers) Vehicle systems can be positive or negative 'common', depending which battery terminal is connected to the frame/chassis. "Negative earth" is the most common term heard nowadays, although it's a dreadfully inaccurate descriptor. The frame/chassis connection is not necessarily at 'negative' potential nor is it technically 'earthed' (or 'grounded') because there's no direct electrical connection to the Earth.
[*For the general reader, Earth potential voltage level is generally considered stable electrically, and conventionally labelled 0V, because it's damp and reasonably consistently low resistance (pretty much anywhere if you go deep enough), but there are circumstances when it can vary significantly. Dry or rocky terrain is often problematic to engineer around. This usually becomes a noticeable problem in high current fault situations in power systems. Research "Rise of Earth Potential (ROEP)", "Touch Potential" and "Step Potential" as a start to find out more about the phenomena and hazards.]

But the last few days I have been pretty unwell again, same sort of symptoms. Achey joints, feverish, tired, bit of a headache, constantly cold. No respiratory effects, no coughing or sneezing, or blocked nose. Wondering if it might be a delayed reaction, or something else.

Bought a video doorbell from ebay. not your ring etc but one that is onvif compatable so it will interface with my home security cameras. Opened it this morning to look.
Fixing box is emty, so email supplier, looked at the chime and no reset button on the back so opened it, No PCB, en empty plastic box, so looked at the doorbell. only two of the 4 screwholes contain screws, opened that, yes another empty plastic box.
OK with knackered hands I aint drilling into brick so gives me a few days. I am guessing supplier had a display pack they mixed up. Lets see how well they do for mistakes, their delivery was excellent next day. good thing I have used paypal and photos sent,

If it ever turns up, and is good - I'd be v. interested in what it is.
Is it data cable to the doorbell or seperate power (battery?) and WIFI?
p.s - an astounding number of people would have fitted that dummy doorbell and spent a long time troubleshooting what was wrong.

Buying a laptop battery week 5
It must be me. I assumed that when I placed an order for a battery for a Lenovo 330S-15ARR, that is what I'd get. Well, I got a battery that is the right shape and it fits but when I start researching it's actually for a Lenovo Yoga xxx. It's the wrong voltage and double the power (which would have been nice). On further investigation, Lenovo don't list any upgraded batteries for the 330S. If I can find this out why can't the seller?
They've now offered to send me another battery (of the same type they previously sent) and I can keep the first one (instead of an RMA, I assume). I suppose if this continues long enough I'll be able to start selling them myself. I pointed out the futility of this and that I'd need a direct replacement not one the right shape. I suspect a refund will not be forthcoming, Chinese companies don't seem to like refunds in my experience.
Watch this space...
It might be easier to buy a new laptop.

I got soaked a couple of times getting caught out in downpours recently and have come to the conclusion none of the 'waterproof and breathable' motorcycle gear is fully waterproof. I think it would have to be waxed cotton or plastic/pvc to be fully waterproof.
ps but riding in really heavy rain with poor visibility /visor steaming up just isn't safe. Pulling over and waiting for it to pass is the only safe option sometimes.

depends on how much your willing to pay. i can without a shadow of a doubt tell you that the 3 layer pro goretex Rukka gear is simply superb and fully waterproof and breathable.. yes its near on £2k for the jacket and trousers but to me been worth every single penny.
i have toured Scotland in non stop torrential rain for days on end and nada water ingress or soaking in of water to the fabric. oohh and Rukka gloves are the ONLY gloves that i have worn that are actually waterproof as well. the water sheds off the gear and is dry for the next day unlike those sillly liners which let the actual outer clothing get saturated in water and take days to dry.
i also have a pair of goretex Sidi touring boots that are fully waterproof.
i have also crash tested the Rukka stuff and walked away after hitting a dear at 60mph and ending up in a ditch.
you pays your money.......

I've never had any issues with my Alpinestars Andes V2 jacket/trouser set. Never got wet in them at all - even in torrential rains.
Same for my Dainese Goretex gloves, & Alpinestars Goretex boots.
And i can now say the same for my Scott DP overproofs too - they are very waterproof, windproof and breathable.

I have an Andes V2 jacket, and it's a great bit of kit, but I do have a warning: It's really designed for touring bikes and works best for what it's designed for (oddly enough). The more your body is leant forward, the more the front gutter gets bunched up, and the more likely you are to get a sudden surge of water on your belly in heavy rain.
I've learned to live with it (mostly by not commuting for the last year and a bit! :o) but if you have a more sporty bike, I'd look at something different.
I'd love a Rukka jacket, but would want a really expensive one and can't justify it. I have Rukka trousers, but they're over 20 years old now and apart from being a bit big for me, are still going strong.
I bought Rukka gear in 1986, the metallic plastic welded type of stuff. It was pricey then but it worked perfectly. Sadly the jacket died about five years later when the zip failed. I had a new zip fitted but it was never the same. I still have the salopetts which are lined, warm and still waterproof, ideal for winter. I also have the simple single skinned over trousers.

I find jackets are fine , but trousers inevitably always give way (as mentioned, aside from Rukka and really expensive brands) dependent on duration and ferocity of downpour.
To be honest I dislike textiles because they are never as well fitting as leathers, can ride up in a crash exposing skin and primarily; the armour moves - so you might find your knee armour is wrapped around your calf or on top of your knee cap at the point a car bumper slams into your unprotected, lower knee. Paired with the fact you never really want to be wearing them when it's sunny and you don't intentionally ride in driving rain my best combo is good leathers and a cheap non breathable boil in the bag suit under the seat I can chuck on when it rains.
Leathers are not good for a commute though so I mainly use textiles for that. When I commuted daily and I knew it was definitely going to rain/heavily I'd shelve the textiles and put on good quality plasticy over trousers that walkers/snowboarders use.
If your helmet doesn't have a 'pinlock' add it to your helmet shopping list. Transformed my riding world (you can see when it rains).

Well, I don't know what that particular lurgy was, but it was really unpleasant.
Started last wednesday with a feeling of slight feverishness, headache. and aching joints It just built until this morning at around 5am, when the fever broke. Couldn't sleep properly, slightly delirious. Got up and 4am, went down stairs, and drank a pint of orange juice and water, and swallowed two paracetamol. Got back into bed, and within 20 minutes the sweat was just pouring out of me.
Finally got up at around 8.15 and my joints had pretty much stopped aching. Head still ached a bit, but that could be dehydration.
Feeling fragile but on the road to recovery.
I lay in bed last night wondering if I was going to have to talk to Steph, and see if she had a plan B regarding my tour this weekend, but it looks like all I need is two or three days of recovery time.
I really hope nobody else gets that bug. Adam, you have my sympathy!

My Lindstand/Halvarsson trousers gave up the ghost last week. They have been good for 10 years with just needing a Nikwax wash in waterproof if they do let water in.
Backing has gone as have the seams on the waterproof liner. I'm now in Screwfix hi-wiz over-trouser on top if it looks like rain as a new bike and cellar conversion have supped up the funds.
When I lived and worked in London during the 80's, I studied what despatch riders wore. It boiled down to two extremes, yellow plastic jacket and trousers that firemen used to wear or the plastic Rukka gear. So in short, buy cheap and replace often, or buy expensive and replace rarely.

people not being able to grasp the concept that there is no ''Ground'' in a DC circuit. its either Positive or Negative... this includes vehicle wiring.
Because a lot of the circuits use the metal frame / bodywork as a return path it is convenient to refer to it as common or ground, and everyone knows what it means.... Nobody making you use the term it it offends you that much. I have been involved in industrial electronic all my working life and loads of people refer to ground. Americans use the term very freely https://mechanics.stackexchange.com/questions/1934/what-are-the-tradeoffs-for-positive-vs-negative-ground
Some DC systems have both say a +24v rail and -24v rail, with a common or 0 volt rail, referred to as ground ( often grounded to a metal chassis in the system ). Grounding one leg of the DC also means the circuit is more resistant to interference.

My Cub is +ve earth, Suzy -ve earth, never heard either way described as ground or common! (But I do understand were Bilbo is coming from)
I used to work on, amongst other things, a platesetter. A laser device used for writing direct to an aluminium printing plate (which would then go on the press). I was in the US and all reference points were to "ground" (which we call "earth" in the UK) so we would measure from the device chassis to the building's ground to ensure we were "grounded" and then check the +5V, +/- 12V etc. to chassis (which was ground). The drum drive motor was 80V dc floating, so you measured between the + and - terminals of its driver, not between + and ground (or else you'd get a spark and a dead drive unit).
I also got into the habit of measuring between ground and neutral because, in the US, it would frequently not be 0V and any time it went over 0.6Vac weird faults would develop.
If we wanted 220Vac, we would take 2 phases but I had one customer with an imagesetter (writes to film) that kept blowing boards and I found that one phase was 180Vac and the other phase was 60Vac so we got 220Vac but with horrendous distortion and noise.
Didn't older Brit bikes used to have separate wires going to each device - ie a positive and a negative wire instead of one wire and a chassis reference?

If they did it was before my time, but could well believe it to be the case as electrics would have been so much simpler then. My push bike dynamo was wired like that (50s-60s)
I had BSA that was positive earth, not 100% sure of the reason why it was wired that way tbh, I was once told that super tankers were wired positive earth in order to keep crustaceans/ barnacles to a minimum from sticking to the Hull!
Don't know if it's true and never felt the need to look it up but interesting theory. Perhaps BSA thought it might keep the rust at bay! ... clearly didn't work.

It was the convention back in the day, we inherited a 56 Hillman Mink - that was positive 'earth' too
if everyone changed the name Ground to Common (COM) in when referring to DC then we would all get along better. we can keep the word Earth in AC.
vehicle chassis connections be it positive or negative are just an extension of the battery terminal they are connected to not an earth or a ground. they are a common that is used as a 'tie point' to supply voltage easier.
lets take a positive COM (commonly called positive earth) setup but use a ship as an example. one would tie the positive to the metal hull then run a negative wire throughout the ship. the negative wire then becomes the ''live'' wire even though its negative. if you can get your noggin around that then you understand vehicle wiring.

I had BSA that was positive earth, not 100% sure of the reason why it was wired that way tbh, I was once told that super tankers were wired positive earth in order to keep crustaceans/ barnacles to a minimum from sticking to the Hull!
Don't know if it's true and never felt the need to look it up but interesting theory. Perhaps BSA thought it might keep the rust at bay! ... clearly didn't work.
They did find that vehicles where the positive battery terminal was earthed to the body that vehicles rusted a lot more, so that is the reason given for changing the grounding to the negative of battery to bodywork. Electrons flow from negative to positive while conventional flow is nominated as from positive to negative ( they originally thought positive ions were responsible for electrical flow, and they did flow from positive to negative ) ,in electrical flow the ions don't move, it is the holes the electrons leave behind in valency band when they move that flow from positive to negative - maybe with positive earthed the 'holes' flowed into the vehicle bodywork :confused:
if everyone changed the name Ground to Common (COM) in when referring to DC then we would all get along better. we can keep the word Earth in AC.
vehicle chassis connections be it positive or negative are just an extension of the battery terminal they are connected to not an earth or a ground. they are a common that is used as a 'tie point' to supply voltage easier.
You're correct about vehicle systems not being technically "earthed" or "grounded". However, I don't know why you seem fixated on AC and DC systems being fundamentally different when it comes to tieing to the reference of Earth.
An AC common (often the "Neutral") might be earthed/grounded or it might not. Both can function perfectly well, especially in multi-phase systems. (An alternator output on a modern car/bike is a 3-phase AC example that works without earthing.)
Also, in non-vehicle DC it is quite normal to electrically connect one pole to Earth, for safety or EMC reasons. In that circumstance I think it would be correct to refer to it as earth/ground as well as common.
At the risk of confusing things, some systems have centre tap. E.g. an industrial 110V supply is actually +/-55V with a centre-tap earth connection in the interests of safety. The only DC-based example I can think of off the top of my head is an audio amplifier circuit - not my area of expertise but I imagine the centre 'common' connection of XLR balanced connections are actually earthed/grounded in some way too.
Your underlying original gripe is valid and shared though: Earth/Ground/Common are being treated as synonymous when they're not! :)

The best phrase I ever heard was 'don't sweat the small stuff' ...... and all this 'is it ground, common or earth' means nothing to 90% of the population who are not electrical designers or research scientists... many words and phrases creep into our wonderful language and take root, and become commonly accepted and well understood - and pretty harmless really - if you say to many 'lay' people 'check the voltage from point 'A' to earth or ground they will check it to body or frame of vehicle, they won't drive a copper stake into the ground next to vehicle and use that.
This gripe goes into 'room 101'....

Insurance! A year's extra NCB, and a year's worth of depreciation, but the insurance has gone up by £70. Time to shop around again.

Replacement doorbell arrived yesterday. Restores faith in ebayers, Now she needs to go bck to her supplier.
Buying a laptop battery week 5
It must be me. I assumed that when I placed an order for a battery for a Lenovo 330S-15ARR, that is what I'd get. Well, I got a battery that is the right shape and it fits but when I start researching it's actually for a Lenovo Yoga xxx. It's the wrong voltage and double the power (which would have been nice). On further investigation, Lenovo don't list any upgraded batteries for the 330S. If I can find this out why can't the seller?
They've now offered to send me another battery (of the same type they previously sent) and I can keep the first one (instead of an RMA, I assume). I suppose if this continues long enough I'll be able to start selling them myself. I pointed out the futility of this and that I'd need a direct replacement not one the right shape. I suspect a refund will not be forthcoming, Chinese companies don't seem to like refunds in my experience.
Watch this space...
It might be easier to buy a new laptop.
Still going...the laptop battery story, still on week 5.
I explained all the above to them and gave them the part number on my original battery and received an email saying: "We're sorry you ordered the wrong battery".
This annoyed me, so I went back to their website, put in my laptop's details and it, again, showed me the battery they'd originally sent, ie the wrong one.
I took a screen grab and forwarded it on to them. They didn't comment but are sending me the proper battery. Should arrive about 8 weeks after I first ordered it.
Meanwhile, I ordered a new laptop today (not a Lenovo). I'll donate the Lenovo to a school (with new battery).

Wasn't my gripe originally, so you need to refer back to Bibio. But if others' are going to "sweat the small stuff", as you put it, then I like to help them to be accurate!;)

An extra paltry £70!
Check this one out. Bought my youngest a pile of Chinese 125cc (bought him a car, he is learning, won’t get a test until next year I doubt) and run a quote through MCN website.
RAC came back the cheapest (£542 third party, can buy a new Chinese bike cheaper then fully comp insurance price)
I phoned them, to add me as a named rider, over 20 years riding experience and no claims the quote goes UP £300.
Insurance for my Tiger 800 is £80 a year fully comp (could have got it for £66 if moved insurance)

they are trying to encourage/force youngsters onto hire plans so when its time for leccy vehicles they can get rid of millions of petrol ones within three years. why do you think that new cars have rocketed in price.. its offset.

So last week I went back to A&E as the pain in my wrists not improving, X rays taken and sent home with a bit of a sprain.
Orthopedics today for the dislocated thumb. he also reviewed last weeks xrays ordered more.
So brace on right hand. As she puts a cast on my left wrist, "You are going to have fun wiping your ass"
bust scafoid and A&E doctor couldn't see it. second time this has happened to me where consultants pick up injuries A&E miss.

The manufacturers have very little/nothing to do with PCP or leasing. The advantage they get is selling more units, as more people can afford a couple of grand down & £400 a month for 3 years. Rather than getting approved on a loan/finance for a £20K car.
Cars these days compared to 10 years ago, are a lot more expensive so they had to find a way to make it easier for people to access new vehicles.
R&D is a huge cost in todays vehicles due to the technology and systems involved - especially where BEV and PHEV are concerned. This is what you're paying for in new vehicles.

Seems that once someone is 'hooked' on PCP they will stay with the same brand of vehicle, so PCP is a good deal for car makers and dealers. All fueled by people wanting a 'new' number plate on their driveway (UK is the only place where date of registration appears on car number plate), I suspect that a lot of people in UK who get 'vanity' plates use them to hide the real age of the vehicle.

Never again on PCP, if you want to keep it then it's the (pretty much) 2/3 of original price in cash now thanks.
Much easier to just do it on HP/Loan, least it's yours at the end and no stupid limits on mileage or some tosspot standing there with a clipboard noting down all the 'Issues' that you have to pay up for before getting out.

unless you know its only for a term deal (eg a company car) and you don't want to keep it, they're ok to send back if you're within the mileage spec/agreed condition of the car. The big issue is not being in negative 'equity' if the market value has changed, or the car is in a higher mileage than the agree time.

Macs can be a total bottom, I reckon it's one of their super worth price tag motherboards that means it goes in the bin - some models are renowned for this, we had 3 out of four fail within 16 months (one had even had a new board under warranty.
Then again I've had other where it was just a memory module.
Whats the exact model Adam?
Does it work plugged in? Might just be the battery. You can pick them up for £20 - £25. If it's the battery it generally doesn't work plugged in. You can test it by plugging it in with no battery in and it should fire up. I'd recommend shutting it back down though after testing it as they can overheat pretty quickly that way
This is on a windows laptop though, never tried it on a macbook. My mac is from 2016 and touch wood i've never had any issues with it

Macbook Pro... late 2015 model.
I was considering a new one soon anyway when budget allows (it's a business cost but can't afford it really now) but it does have important recent accounts and invoices saved on it. It was backed up about 2 months ago, so really want to be able to get it running.
I've got a genius bar appointment tomorrow.

Logic board has gone apparently. They couldn’t work it out at my appointment but held onto it to diagnose and have just got back to me. £480 to fix.
I ordered something, which was in stock, on Friday for delivery today, it never showed. I have emailed the company 3 times today and only received an auto response saying they're extra busy. I have no idea when it will be delivered. What's surprising is that it is Sportsbikeshop - I've used them many times and their customer service has been flawless, but not today.
Which courier was it with? If it's Royal Mail then it'll be a day late.
And why not call, rather than email 3 times?

DPD (next working day) and email is free (since I'm paying for the 'net anyway). Surely the question is why they're not answering emails not my choice of communication?
I suspect that their stock level was incorrectly tallied since they no longer list the colour I ordered and I'm guessing it's out of stock. Since I placed the order on Thursday evening it's annoying that they haven't yet informed me.
I'll call and cancel the order tomorrow and look elsewhere.
Unusual - i am guessing you did not get a DPD dispatch notice, which would confirm the delivery was not due.
Do you not get free calls with your mobile or landline? I do with both so would not consider it a cost. TBH i am fairly sure, like most people/companies these days, the emails are busy and they get round to it when they can - pretty sure they have more than just 1 customer with an issue/question/query

Maybe it's me then but I find waiting all day for a (non-existent) delivery when I could be riding, infuriating. When their website declares: "next working day delivery" I don't consider it unreasonable to expect that.
If they don't have stock, tell me and I'll look elsewhere.

That would have been my guess. It's an absolute joke isn't it 2015-2018 (+ ?) were bad years for logic boards. We had nearly 100% failure at work, great deal when they're double the cost of a similar less trendy laptop.

Oh ,yes ,I agree ,if you were actually waiting in all day to receive the delivery, that is infuriating. I have had deliveries left in a safe place, left with neighbour or left for collection at local post office, for example, to save having to wait in for parcels.

See avatar. That is the oil filter on my September 2021 sv650 after about 4,000 miles. I have never had the paint finish flake off an oil filter like that before on any bike . The dealer and Suzuki don't want to know under the warranty , saying it is not a manufacturing fault and something has 'got at it', whatever that is supposed to mean. Obviously corrosion will occur if the paint flakes off to leave exposed bare metal. I know it will be changed at the next service but the starter motor finish is poor as well. I would say the paint finish is part of the manufacturing process ! Anyway, a different response and after sales service from Suzuki compared to Honda. The paint came off in places on the exhaust silencer box on my 2018 Honda CB650F and Honda replaced the whole exhaust system under the warranty!
