Hi
I have a Mediacom 910 tablet that i flashed with a CM9 rom.
Worked fine for weeks, i turned the screen off to go to sleep one evening and the next day it would not turn on.
Put it on the charger and waited several hours.
Now when i press the power button all i get is a white battery icon in the middle of the screen. Inside the battery is an orange triangle with an exclamation mark inside.
What can i do to revive this unit...It must have charged the battery because now it will turn on like i mention above without the charger inserted.
I also measured that the charger is giving out 5 volts and the same thing happens when i plug in the micro usb cable to charge with that.
Anyone have any ideas what to do (Besides throw it away )
I've the same problem. I've opened the device to check if the battery link was ok. Any suggestion?

Hello All, My S3 will not do anything, Wont boot to diddely squat!! A few days ago I got home from work and I plugged it in as i do before I went to bed. When I woke up I checked my phone for msg's etc. and nothing SO I thought the charger had become unplugged (its happened before so I wnet downstairs and plugged it in to an alternate charger and nothing!! no Battery icon, when I press the power button no Samsung logo no LED indication, Thought maybe the battery was bad, tried the wife's, same thing. Took the batter out, let it set over night, Nothing!! I now get a red LED indicator when I plug it in which goes away after a minute or so. When I plug it into my computer, the computer regonizes that something plugged in but won't recognize it as a phone or any specific device.
I was running CM 10. the latest release version, and hadn't changed in a few weeks.
Any help???

We've had a pair of Nabi jr tablets for about 6 months, my youngest daughters Nabi jr seems to be having an issue. % days ago, she brought it to me, because she said it wouldn't turn on, assuming it had been off the charger, I told her to put it on and the next day she could play with it.
The next day comes and I go to check on it, I unplugged it from the wall charger, and tried to turn it on. Nothing, just a blank screen, so I plugged it back in, and noticed the screen flicker a second, not light up, but flicker like the screen got power, so I pressed the power button and it turned on. \
After booting up the battery said 0%, so I went into setting and to battery and it says Battery 0% status Unknown. I've tried everything to figure this out, I even took the back cover off to check the battery, and using my multimeter, it says the battery is getting the charge. But for some reason it won't run off the battery, only when it's plugged into the wall charger.
Any help would be greatly appreciated.
Hi Guys,
I have a tablet that my boss gave me today to 'fix'. The problem that it is having is that it isn't turning on, nor does it appear to be even charging. He said he used it until it was dead, then plugged it in overnight to charge, but when he tried it this morning, it wouldn't turn back on. I've had it for about two hours now, plugged into an outlet (the plug is a bulky black 2pronged adapter with samsung written on the side and I have a usb 3.0 plug). I tested the charger out on my Galaxy S5 and it started charging without any problems, so that tells me that the charger is working.
After 2 hours of supposedly charging, when I press power nothing happens. When I press the home button, nothing happens. I read on here that some were having really slow charging times, but I figured after two hours, there should be at least enough power to show the little batter logo on the screen during charging. Now, though, since that indicator doesn't even show up, I'm starting to think maybe I should just take it back to VZW. I was looking at the back of the device to see if it had a removable back cover and maybe resetting the battery would fix it, but I didn't see an indention where you can pull the cover off at (like on the note or my s5).
Any suggestions?
2 hour are not so much, if you used not the original charger. Let it on the charger for around 12 hour and try again - disconnect charger, reconnect again if you can see something...
Plug it in, keep the power button pressed for at least 30 seconds. See if that starts it up.
Hi.
You might try getting an usb volt- & ampere-meter off ebay. They're about 10 bucks or so.
It'll tell you if the tablet is drawing power at all.

Hey guys,
a few days ago I accidentally dropped an HTC One E8 in water and obviously it doesn't work anymore. Before buying a new one I wanted to ask, if some of our "HTC experts" may have suggestions on what else I could try before giving up.
The situation: I dropped it in water, didn't turn it off (dumb, I know) and it worked for around 10 minutes until it powered off. I left it in rice for a day and it didn't turn on or charge. At this point I nearly gave up.
I left it for in rice (about 48 hours) and - the orange led was flashing while charging. Even the screen turned on and it showed a charging symbol first and after a few seconds it showed a red circle and a white exclamation mark. After some time I could power it on and the touchscreen worked and I could use it, but it still was around 1%/0%. The screen flickered, but it was usable. I wanted to plug it in my computer then to rescue some data, but 5 seconds after I took it off power (to switch from the wall charger to my PC) it died.
Now I tried it to power it on for like 2 days, but with no charger connected nothing happens and when I connect the charger, the orange led is on constantly. I tried power/volume- and power/volume+, but nothing happens. Not even the charging indicator comes up, the screen is completely dead.
Are there any steps to try before giving up? By the way I don't want to disassemble it
Thanks in advance
I have never had any problem with my Nexus 5. It is now my standby device. Accordingly it doesn't get used much. One day I left it ON and didn't use it for 2 weeks. When I picked it up again it was OFF and didn't want to turn on. Naturally I thought the battery had drained and put it to charge.
Instead of the battery symbol on the screen (indicating it is being charged), I get a sequence of 8 red blinks on the bottom notification light (which is just above the charging port), each blink lasting 0.5 seconds, then 0.5 seconds off (so total duration of blinking sequence is 8 seconds), then 1.5 seconds off, then blinking sequence starts again.
I left it connected to the charger for 2 weeks. Nothing changed.
I then replaced the battery with a brand new OEM battery, same thing again.
I cannot get into recovery mode nor is the phone recognised when I connect it to the PC.
Any ideas? Anyone knows the meaning of this blinking sequence?

what is the current state of the phone? do you just get the blinking when charge cable connected? no boot loop ?
So currently the phone doesn't switch on and cannot be charged it would seem.
There is no bootloop.
And yes, the blinking only goes on whilst a charging lead is connected or whilst it's on a wireless charging cradle. No blinking when removed from the charger.

you said you replaced the battery , I would check that connection , try removing the battery if possible and reconnecting it. Try the old battery too if you still have .
In my experience i'v seen that blinking light in other devices when they overheat.
I only replaced the battery because of the blinking problem as I suspected a deep discharged battery. Anyway the connections are good. 100%.
I never had overheat issues on my N5 as it was just used for basic functions, no gaming etc. I wouldn't imagine the device had overheated while it was left unattended on my desk, and there definitely is no overheating happening now as it doesn't even switch on...

sounds like your hammerhead finally checked out ... the old saying goes " if you don't use it, you lose it " .... try all combinations like hold power and volume down at the same time for 10 seconds , power and volume up ..etc
other than that i'd take a multi meter and make absolute sure you have power to the motherboard , then if you still do, it could be a short ..
if you want to go even further, a complete tear down of the phone, check for corrosion ( whitish residue on terminals and motherboard ) clean off with toothbrush only ( no water or liquid of any kind ) be careful removing ribbon cables and re-inserting them ... you can find lots of stuff on youtube for that.
good luck
