My Touchpad stopped working about 6 weeks ago and I'd like your input on:
what the problem might be
how to erase my data should I choose to sell it for parts
One evening I was web browsing and I noticed the back of the TP got very hot (I had over 50% battery remaining). So I turned it off and went to bed. Next day it refused to turn on. My TP has CM10 installed but I was using WebOS when I experienced the heat and turned it off. I did the following to try to get it working again:
drain the battery by letting it sit for 2 weeks, then again for 3 weeks
tried every button combination to restart the touchpad (holding down and repeatedly pressing)
charged it using the USB charger (it works since it charged my phone)
charged it using the touchstone
plugged it into my computer using various USB cables, but no response from TP or computer
The only sign of life I get is the rear of the TP gets hot when I charge it (USB and touchstone), but it won't turn on not matter what I do.

Do you think it's a bad battery? I don't want to spend $20 for a replacement battery if its a different issue.
I've been thinking of selling it for parts since I plan on getting the next Nexus 7 tablet (rumors say July - October release). How can I erase my data before I sell it? Can I remove the flash memory? I opened it but haven't unplugged anything yet. I followed the instructions at: http://www.ifixit.com/Guide/Installing+HP+TouchPad+Battery/6082/1
Have you tried holding down the power button and the home button together for 10 seconds or more?

It sounds like a hardware problem to me. Maybe someone else can chime in to help.
Good luck.

My MI-410 is bricked. It is not booting up, no keypad lights. At first tried to connect it to my laptop without inserting battery and then insered the battery. The phone started at that time.
But then it again bricked after 2-3 days. And it is not starting since then. I tried the the same procedure but no help now.
I tried the procedure on different computers too, but no help.
Please help me, as I really loved my device. It is completely dead. At service center they said "We can't help you". They can't do it.
Any help will be appreciated.

how did it happen...
just try to boot in fast boot mode. if this works your MI410 is not yet dead.
In case you had nandroid backup before everything went wrong, you should be able to restore your system from recovery.......

Can't open boot mode. The problem happened since when I was flashing a new ROM at midnight. I got asleep and my phone was in CWM recovery for whole night.
When I wake up, the battery was gone and my device too.
None of the methods work. No boot options nothing. Only red LED notification light when connected to Laptop.

plug it to the power socket for few(2-3) hrs without doing any thing. then ur phone should get back to normal.(dont use laptop for charging for this time)
this happened to me once. this is because of zero charge in the battery. the battery needs some juice to become normal.
else you can try to switch ON with spare battery if you have one.

Went to a mobile repairing shop. They said its a hardware issue, and they mend it for around 450 INR.
Feels a good deal. Lets see what they can do. Will go there today.
Meanwhile thanks @reversegear for your kind help.
Also my battery feels a little inflated, maybe the battery is also gone.
Hoping for the best.
Hello,
I have purchased a Raspberry Pi 2 along with a Sandisk, class 10, 16 gb microSD card.
Installation of OSMC went smoothly with no errors. Later on I proceeded to connecting the RPi2 to HDMI, ethernet, keyboard AND ONLY THEN to the power supply.
The result was 2 leds (PWR&ACT) were constantly on (no flickering) and not boot was happening.
I unplugged from power, made sure everything was connected ok, then reconnected to power, the RPi2 booted properly.
Thinking I probably poorly conncted the RPi2 at first, I just proceeded and used it for a couple of hours, then turned it off (via shutdown in kodi) and went to bed.
This morning, I plugged it back in to power, and guess what? same thing again, both leds constantly on and no boot. Again, unplugged from power, plugged back in - and vualla, boots up normally again.
To make sure, I shut it down a few times and booted up again, and worked ok.
The only common denominator I can think of is both times this happened the RPi2 was turned off for a long period of time.
What am I missing here? SD card is recommended and working fine (if not, how does it boot), everything is connected properly. What could cause this issue?
Again, after the "first bad boot" it starts up find after I re-plug it to power.
This happend twice so far, and I couldn't find any answers regarding this issue (couldn't find posts describing ACT as constantly on).

Ah, this happened to me
Probably this OSMC is not very stable, and you might need to downgrade to a more stable version. Anyway, to be sure check to make sure by running rAspbian or something instead, and see if you get the issue.
Cheers
Disconnect HDMI cable when pi starts to boot. Then connect again when lights start to flicker.
Could be the power supply isn't quite up to snuff... Disconnect keyboard and try.

Power supply. Needs to be 2 amps or more

Hello,
Today I noticed my phone had died earlier than usual, so I went to plug it in and charge it.
The green bolt and circle appear to let me know a charge is commencing. That was followed by the unexpected disappearance of that screen and the Huawei logo and "Powered by Android" text appearing. Not a usual procedure. Usually, the phone would show a percentage and a circle forming around it as the charge grows.
The moment I unplug the phone, it instantaneously dies. There is no perceptible delay. Thus, I can only attempt to enter recovery mode or fastboot mode when connected to a power source. It does not seem to make a difference if the power source is a regular PC 5V USB port, a charging port or the original AC adapter and cable. The only perceptible difference is that whenever it shows the Huawei logo, it reboots quicker if connected to PC.
If left alone for an hour+ the phone does not go out of this boot loop state. I have tried holding the power button, holding the power button and volume up procedure and holding the power button and volume down procedure.
The only reaction I get is when plugged to PC and trying to enter fastboot. It briefly flashes a screen that one cannot read for the milliseconds it is shown:

The black you see above is an artifact from a video recording I did, from which I took out this frame. To the human eye, the entire screen seems to light up and go out immediately after.
Here is a video of how the phone acts if I hold down only the volume down button while connected to the PC via USB. The second item in the post is the screenshot of what is visible for a few milliseconds:

Hello,
I had exactly the same issue, after trying everything i could i replaced the battery with a new one and my problem solved. You can try if it works for you too the battery is cheap i got and for under 10$.
To change the battery is a bit tricky i managed to unglue the battery from screen without breaking it but i can't tell the same for the back cover which i cracked it while trying to remove it.
Please confirm.
Thanks.
Is it 85% max?
I wish we could set it manually to something like 40% too.

Does this require a restart OR does the battery just stay at 85% despite being plugged in?
Does it switch to bypass charging?
I wonder if they've released the source-code for this.
on s21 ultra. at 14%, it shows 36m until full (85% max).

I don't understand.
Is it drawing power from the cable whilst at 85% in order to stay there? (called bypass charging)

Nope. When I unplugged phone in the morning it had dropped to 82. So seems to stop at 85 and shuts off. Maybe to only start charging again after you unplug and plug back in? Haven't tested that theory
I like the option regardless
