First off, I'm about to RMA my device to evga because of a charging issue. The tablet, when plugged in to charger, will show that it's charging, but it's not, I've left it over night to find in the morning that it's still showing that it's charging but the battery level has actually dropped. It's still under warranty, so no biggie. Just strange, never heard of this problem before, I've tried different cables and plug adapters, nothing makes a difference. I can get it to charge with a great deal of fussing with the cable, ie unplugging and plugging it back in to both the tablet and the charger.
No big deal, I'll send it in for replacement.
But wait, there's more....
Apparently, if the sticker with the s/n number has peeled off, your warrantee is void. The sticker, on the back of the tablet, in the exact position as your hand would likely be while holding the tablet in portrait. Now I can understand this on a computer component, it sits in your tower and doesn't regularly get handled. My sticker peeled off less then a month after having the tablet, and I had no idea that it had until I tried to rma the tab. You can use the s/n sticker off the box if you tape it to the tab with clear tape, thankfully, but if you don't have your box or the sticker, even though you can view the s/n from the settings, it will be immediately rejected and sent back to you.
So just an fyi, keep your box with the s/n number safe, because that little sticker is eventually going to come off.
What sticker? Advent ones don't have a sticker?

Just wanted to check. There are contacts on the rear cover, that go to contacts in the phone. Can anyone confirm what these are for? I want to say that the antenna is in that cover, and these are to connect the antenna to the phone. I'm about 95% sure i'm right on this, since i lose a few bars of signal when the rear cover comes off, just wanted to make sure i'm right.
I saw this thread and asked the rep while I was in the store today for warranty stuff, he said he has no idea and that it's either for antenna or inductive charging on a supported charging mat, like the palm pre has.
He showed me what the wireless charging thing looked like on his palm and it looked similar. Apparently you just set the phone down on a mat and it charges.
Don't know if that helped any, but it would be cool if it was for charging. I'll keep my eyes open for any accessories that would confirm this.
The back cover is indeed the antennae. And no, it (unfortunately) has nothing to do with a wireless charging method.
As of last night my A500 will not charge. I left the device overnight and unfortunately now have Zero charge.
- My charger makes a noise, I think it always did, so I'm assuming the charger is OK.
Can anyone confirm that the chargers give off a kind of electrical buzz when working?
- I get no light at all on my A500. If the charger is OK I'm thinking something has gone within the tab, be that circuit or battery.
Any ideas or tips here?
- Sadly I do not have a multi-meter to test either the charger or the tab, no friends with a similar device, I've lost my proof or purchase (which is painful and rules out warranty), and am a bit stuck what to do.
Any ideas?
- I've heard/read that allowing the power to drop too low can cause a problem. Obviously Zero is bad in this case.
Can anyone confirm this rumour or suggest a fix?
- I did try entering recovery and resetting the battery stats - whether this made things worse or not is unclear - it certainly did not help.
ANY HELP OR IDEAS WELCOME (bear in mind that I have spent quite some time searching and trying other peoples' ideas already though.
Thanks,

Quit guessing and get the charger checked
In reply to myself and to help those with a similar issue.
Yes a charger my buzz when good OR bad. The trick to seeing whether it is working or not (aside from it charging the pad) is to see if it gets warm -- no warmth, probably broken.
As for measuring with a multimeter the trick is to insert a paper clip into the small hole in the plug and measure the voltage between the outer plug (negative) and the paperclip (linked to the positive). Few multimeters have pins that will fit inside the super tiny plug on the A500 charger so the paperclip is your way in - obviously be sure not to short circuit the thing!
There are many chargers available out there. In Australia Jay-Car and **** Smith both have perfect chargers, the correct type, voltage, amps etc, they even come with multiple pins -- sadly none fit the A500!
My solution was to go to Infinity who are a provider of Acer spare parts. They have the correct charger and are easy to deal with BUT -- It's not cheap! They want $40 for the charger and a further $30 for the little bit on the end that gives the plug its nationality. In most cases we do not need this though as we can reuse our old one, but hey, not cheap all the same.
Still, it works and I'd rather be ripped off than get the wrong thing and blow the mother board.
NOTE: if you do get a charger from anyone other than Acer or a supplier of theirs - be sure to match every detail of your current charger - especially polarity.
I had problems with charging on my A500. When I plugged in the charger the power button would turn orange for a few seconds and then start flashing white.
I took the back cover off and found that the wire to the centre pin of the power connector on the tablet had almost broken off. I touched it lightly and it came away. Re-soldering the wire fixed the problem, it now charges as expected.
After fixing it I measured the charge current. It starts at a small value for a few seconds and then jumps to full charge rate. It seems there was enough of a connection to handle the small current but as soon as it switched to full charge current the voltage drop across the remains of the connection was too much and charging stopped.
Charging problem
I too just experienced the no charging problem. I looked up how to open up the tablet and tried to trouble shoot the problem myself. My problem turned out to be a very easy fix. The Posative lead on the back of the charger port had come loose, a simple touch of the soldering iron and its fixed. I thought since I had it open I might as well go ahead and change the battery too since it was 4 years old. Its an old tablet and time to turn it into a hand me down for a lucky niece or nephew
My nexus 7 doesn't turn on or hold a charge. I plug it in to the wall and the charging icon will come on for five seconds, then the whole screen will turn off. If I unplug and plug the usb cable back in the same thing will happen.
Is there anyway to fix it or am I screwed?

How old is it? Is it old enough that the battery might be dead? Maybe the battery connection is simply loose or disconnected.
This shows you how to get to it : http://www.ifixit.com/Guide/Installing+Nexus+7+Battery/9895/1
(it's also the same guide you would follow if you wanted to buy a replacement battery and install it, otherwise if it's just the cable you can plug it back in and secure it).

It's less than a year old. It did suffer some water damage. I turned it off and put it in rice for a few days. Now I'm trying to turn it on and this is happening. I made sure there was a good connection with the battery. I also took it apart to make sure nothing was still wet and all the connections seemed good. I've also tried different cables and chargers. The original cable that came with it is damaged, but I've tried 3 other ones. Same result

Even if nothing was still wet now, there could be some corrosion in the internal parts, or some other parts could have simply been shorted and as a result would need to be serviced. If a new battery doesn't do the trick then it's probably something on the mainboard that has been shorted.

I will have to try a different battery. However, is there a way to get a replacement mainboard? I'm pretty sure the warranty is voided now.

eBay, or maybe the iFixit site might have parts, but usually when it comes down to needing a new mainboard, cost-wise you would just get a new one, and then sell parts off your broken one to make up for the difference.
Hi,
I just recently had to have my charging port resoldered into my Motorola because it finally failed and ended up coming out of the phone housing on the charger connector. Prior to that, the phone was connecting to the charger, and I had two I was using. One in my car and one in the house. After I the port fell out, and until I could take it to a phone fixer, the workaround was I was charging and swapping out batteries with a Motorola Blur. What was weird is that both phone housings look identical; however, the older phone would pick up both chargers, and my Defy would not.
After they soldered in a new charging port a couple of days ago I left with clear assurance that everything was working great, and charging was a-go. Mmmhmm. On my way back home, which was an hour from the repair place, and tried to hook it up to the charger in my car. Still not charging. When I called the repair place they suggested checking it with my home charger too, once I got back home and then let them know if there was still a problem. They reassured me they had hooked up to several chargers while it was there, and all were good.
I got home, tried the home charger, and still no connection. This time when I called them back I got another person who started asking about my charger and the little lines on the underside of the metal piece that inserts into my phone. She asked if the metal tracks met the plastic on the back end of the charger itself or whether they stopped with a gap between the tracks and the plastic housing. On both my chargers I saw the tracks did NOT meet the plastic, and she said they only use Samsung chargers in their shop because it creates a better connection, and some phones need that.
Pretty sure the chargers I have were not OEM chargers for this Motorola so I am going to try to get to a place with Samsung charger so I can puzzle this out, but I am confused in that one Motorola charges and the other doesn't.
Any experience or ideas or suggestions????

Hi,
Please can anyone tell me whether the little connector on the vibration motor is supposed to be soldered to the motherboard or does it just touch at a certain place?
I've already posted another thread about having replaced the battery but it doesn't seem to charge.
Without going into details all over again, a local repair shop replaced the charging port last week - my phone was returned in seemingly working order but they had assured me a bulging battery was OK. I charged my phone but the battery was draining quickly, which was what led me to research a bit more and discovered how dangerous it can be so I ordered a new one.
In the process of fitting the new battery, I discovered half the screws in my phone missing, no copper tape, plus there is no black rubber cover over the charging port & vibration motor as is shown on the guide for replacing the battery on the fixit.com website.
So I'm wondering if the small square 'connecctor' (?) part of the vibration motor ought to be soldered to the motherboard or is it just normally held in place by the black rubber cover? In my phone now, the 'connector' doesn't stay touching motherboard so I'm not sure if this would affect the phone and stop it from functioning or would it just mean the vibration wouldn't work?
Would this affect whether the battery could charge or not?
(Incidentally, I discovered that the the battery connector was upside down compared to the pictures in the ifixit.com guide (the red wire was nearest to the battery instead of the black wire being nearest) so I was hopeful that by correcting it to match the picture, I would have solved the problem but unfortunately, it didn't make any difference. When I connect a wall charger, the screen just flashes and when I connect it to my laptop, it just gets a blinking white led but nothing more. It seems strange to me that it wouldn't make a difference - is it like a usb-c cable in that it can go either way round?)
The battery seller asked for photos of the new battery in my phone and has now offered to replace it - is this likely to make a difference or is the vibration motor not being attached to the motherboard the cause of the problem?
I'll be so grateful for some help.
