HD Turns Off/On at Random Times

Hi all,
This seems a rather frustrating way to announce yourself to a community (other than to Fallen Spartan - thanks again for your help) but I need some help. The problem:
A couple of days ago my phone started to turn itself on and off at random points. It will bring up the 'Do you want to turn your phone off YES/NO screen' and even if I say no it will reappear until I say YES. This also cause the hard on/off button to stop functioning. I have been rectifying it by pulling the battery out, putting it back in, letting it turn itself back on (note turning ITSELF back on), letting it boot up, from which I can turn it off. Leave it for a min and then turn it on again. As you can imagine however this is a painful process and one I'd rather avoid on a daily basis.
I have noticed a bit of a pattern and this error often occurs in the morning after taking my phone off charge (I leave it charging overnight). In addition I haven't installed anything in the last 48 hours (the start of the issue) other than the media player mentioned here;
forum.xda-developers.com/showthread.php?p=3248642#post3248642
and the new Dusk Theme....however it was doing it before this was even downloaded.
Anyone else experienced this and more to the to the point has anyone fixed it?
Thanks

No one....?

I had my phone in my pocket while jogging in the rain. The phone didn't get really wet, but from then on the power button is now "stuck". The button is permanently pushed in. (The button appears normal, but the contact inside the phone seems to be stuck closed).
The result is that the phone acts like I'm always holding the power button down. Here's what now happens:
- when I insert the battery, the phone automatically powers up
- when the phone finishes rebooting, the PowerOffWarning.exe application crashes (this is the app that runs when you hold the power button down for a second and you get the Power Down options/Slide2Shutdown (shut/restart etc.)
- battery life is drastically short - the phone runs on a full charge for maybe 3 hours, because the power button is constantly sending interrupts to the phone's CPU which in turn can thus never go into low power mode
- battery drains totally. Normally, when the battery gets low, the phone shuts down. Since the power button is pushed in, the phone is forced to wake up, using a bit of the remaining battery, but then shuts down since the battery's too low. This repeats until the battery is so dead that the phone can't actually power up enough to start the power up sequence.
- the phone constantly reboots when on a charger after the battery has been completely drained. Since the battery is so dead, when it's plugged in to a charger, the phone has enough juice to reboot, but during the power-on sequence the screen turns on which uses too much power, and the phone shuts down. This repeats until the battery has enough charge to handle this big load. It takes 5 minutes of constant rebooting before it charges enough.
I took the phone apart and examined the switch but I couldn't fix it. The circuit is available on eBay but it's really expensive (USD$140 I think).

@GreedyFly
Have you tried the basics like a hard reset or re-flashing a rom?

THIS!
This is a very similar, though slightly more extreme version of what is happening to mine.
@Stuntdouble yes I have I am afraid I have and played with various tweaks.
Any ideas if connector cleaner (something like Servisol) would sort out the connections or is it more likely to harm?

I have an almost identical problem after water "damage" Did anyone come up with a fix/repair???

the fix is to take the thing apart, to the point where you remove the power button PCB, and CO Contact Cleaner the hell out of it, press it while its detached a bunch of times (when i say detached, its still connected to the main ribbon but not clipped into the housing), clean the physical button plastics, and slap it all back together.
theres a picture of the power button circuit board out of the housing in the bottom link of my sig.

Red LED of Death

Not sure if anyone post it already.
After using the phone for 2 months, I've just experienced the red led issue.
The phone just shutdown suddenly with 4X% remaining when doing benchmark that charging with USB. It just turned off and followed by the red LED.
At that time, I thought I was fxxxed!
I tried to plug and unplug from the PC but no luck, it just popped out the "Google" logo and then the red LED lit up and repeat and repeat.
Then I plugged in the PC again and pressed power on + vol up, it allowed to go to bootloader but soon it shutdown, which means the hardware has't died.
This time I plugged it in the AC charger, the red LED started blinking.
Luckily, charging animation appeared and the phone can be turned on just charged for few minutes.
After turning on the phone, only 1% left.

But I don't think It can drain the battery within a minute, so I decided to reboot the phone.
After reboot, I got 56% left.
Then, I got a conclusion that the red LED may be caused by the wrongly calibrated battery or overheat.
Sorry for my bad English

Or just a bad battery in general. Happened before on the htc phone I had.

Thanks for the screen shot.

Here you go this has been talked about before many times. I had the same issue happen to me and posted just like you and got some more thread links to more people that has happened too.

its just that benchmarks pull a lot of current suddenly from the battery and it cant keep up (try turning on a crt monitor while powered from a 360W ups.. the ups will turn off)..
so once the voltage in the battery drops because of the load.. the phone thinks the battery is dead.. so once you give a little time to recover and charge it for a little while.. the voltage will stabilize and it will all be a ok

There are multiple reasons for the red light. Mine got it while running antutu. Was totaly unresponsive, but could get into bootloader to fastboot the stock images back. No luck on that (still dead) so I had to RMA it

Just had this happen to me Friday night. The batterry went dead so I connected it to the charger and it turned on but then it rebooted and the red LED came on! :/

Happened to me on stock with the phone on the charger overnight. I couldn't even get into fastboot, but pulling the back off to reset the battery fixed it finally. It's such a common problem I halfway believe the LG-sourced batteries have an issue.

Theres a fix for that. Open back cover, unscrew battery connector, disconnect it, and connect it again. And dont screw it. Put the back over on and try to turn on device.

Hey this just happened to me my phone was showing fully charged and then just went black put it on charger and booted up. I'm in cm10 nightly with latest Franco kernal
Sent from my Nexus 7 using Tapatalk 2

This happened to me running the stock rooted ROM and Franco Kernel (Milestone)
The phone had died a few times, each time going to a red flashing light and would eventually power on. About a week ago, it happened again but the red light was solid and would not power on. The Red LED of Death.
I left it charging overnight for a few days and today managed to power it on. Before trying this jump-start method, I advise leaving it to charge for a very long time (several days). After around 12 hours it seems that the red light goes off. At this point I unplugged and plugged it back in, showing the red light again. I hope this helps someone else fix their phone.

[Q] Battery indication weirdness

Help!!!!!!!!!
I charged my Nexus 7 2012 32gb yesterday morning, and took it off charge in the afternoon. I lightly used it in the evening, and it probably went to bed on ~60-70% charge. My alarm went off as usual at 07:00 this morning, and as far as I can remember, when it woke me up with that alarm the indicator in the top right was in roughly the right position for ~60-70% charge. Come back to it 5 minutes later after getting dressed, I tried to dab the power button to wake it up. That failed. I tried holding it down, trying to turn it on (it randomly turns itself off at times, for the record, so I suspected that). That also failed. I plugged it in to the charger, and it displayed a black screen with the occasional fuzzy rainbow line flickering on the screen.
In absolute panic, I googled this on my phone, and everybody recommended to take it back to PC World, apart from this one person, somewhere, suggesting to unplug it, leave it alone for a while, and try to turn it on then.
So I did that. I waited half an hour, and tried to turn it on. It successfully worked, apart from the fact that it suggested to me it had 0% charge, which is frankly impossible. Nonetheless I plugged it in, and the battery interface in Settings seems to be doing all kinds of weird things. For starters, I've charged it for half an hour, and it still is on 0%.

The first photo shows it on its lock screen, plugged in. Note it asks for me to plug it in a charger, but in the top right it alleges that it is plugged in, due to the lightning bolt. Weird.
Take picture 2. 0% charge, same as what the notification drop down says. Then "Unknown". Wonderful. Normally,that should say charging, or not charging. But "Unknown"? That doesn't sound good.
Then picture 3. The battery usage graph. My understanding is that batteries discharge on a gradient, often a steep one, but not exactly the cliff drop here.
What on earth is going on, and do I really need to take it back to PC World, or can it be fixed?

EDIT
I've got advice elsewhere and my fix was simply turning the device off, power cable out, then booting it to the Android Bootloader. From there I selected the shutdown option using the volume and power keys, and waited till I was sure it had shutdown. With the off device, I plugged in the power cable, and then turned it on normally. Problem solved.

Broken - help please...

I have a relatively new (refurbished) nexus 7 (2012) that got a sudden fault of not turning on at all.
When plugged in I get the normal charging icons (central screen) as when the tablet is off.
Unplugged it does nothing with any button press: power, power + all combination of volume buttons.
Pledged in it does something only with power button - backlight turns on with dark background and flickering stripes of static.
Plugging into pc shows nothing.
It's been sent if for repair and they said the battery was ploughed in backwards! And they've swapped it around.
I don't get how it worked for a month if it was the wrong way around in the first place.
Sent back to me this week with no change!!
Suggestions of ways to resolve it my self?

You can open the back plate of the Nexus 7 yourself. It comes off fairly easily. You can then see if the charging port is clear of debris, if it might be slightly bent out of shape, or if somehow the battery is connected backwards... LOL. That seems highly unlikely to me.
What you are describing sounds more like sleep of death, or what happens when you drain the n7 battery completely. Something is wonky with the firmware and it "forgets" how to charge when the battery is too low. Doing this off the top of my head but I think what you are supposed to do is;
1 - plug in charger, which starts the charging animation.
2 - hold power+volume up+volume down to boot into the bootloader
3 - using the volume buttons to scroll, select reboot (or recovery)
4 - quickly unplug then plug back in the charging cable. Timing is key.
There is a thread in the Q&A forums with other methods if I didn't write that down right, or it if doesn't work.

Problem solved!
I popped open the back cover to find the connection from the battery to the main board nut fitting tightly all the way in (only by about 5mm). Pushed it in and secured it.

Replaced the battery twice, still will not charge fully.

Hello all.
Strange problem I have. I replaced the batteries in both my Moto X Pure's. One is a hand me down, the other my own. I replaced the batteries in both. But the hand me down one only charged to 85-86%. Thinking a bad battery to start, returned the battery and bought a different new one. Installed that one and same result. Only charges to 85-86%. Other than that, phone works great. Battery does hold a charge long started at 85% than it did with the old battery. Haha
I inspected for any physical damage. Looked to see if the battery or anything else was contacting anything it shouldn't. Everything looks identical to the other phone I replaced the battery in. Nothing lose or broken. Did a full drain of the battery ( if I did it right.) Then recharged it for all day. Still, only 86%. If I turned it on, will will say "Full Charge in 3 hours" or 2 hours. A day can pass and still will say the same.
So any ideas? 2 different batteries from 2 different brands and still the same issue.

Enter the bootloader, navigate to the bootloader logs entry (if the Moto X has one) and long press the power button until the device shuts off. This will clear the bootloader's logs as well as any residual stats related to the battery. Your battery should then display the correct amount, or charge fully to 100%.

UPDATE: I got it! Just held the Power and Volume Down button for a long time and it rebooted!

Thank you for the reply! I did as you said but now it is just stuck at that screen with the Bootloader Logs.

Ok so holding down the Power Button when the Bootloader Logs option is on the screen doesn't shut off the power or anything else. Something different with the Moto X Pure? I held it for about a minute (and my thumb was losing blood lol) and it was still just at that screen. Also, because of that, I cannot cycle to the other options in the Bootloader menu. I have to hold power and volume down until it reboots. Have been looking up anyway to clear the Bootloader Logs on this phone and your suggestion (which seems to work on other phones great) is the only one I see. So weird.

I replaced the battery with a OEM one. Actually found a supplier for the OEM battery! Replaced it, connected the charger to it and guess what? Again, only to 85%. But this time, it doesn't say 2 hours to full. It just says TurboPower Connected. Oh and with the OEM battery, I did what you said to clear the bootloader logs and it did actually shutdown like you said it would. But, the battery is still showing 85%.
Should I let it drain to 0% then try to have it charge fully again?

It won't hurt to let it drain to zero and then recharge.
