[Q] HTC HD7 wont power off - General Questions and Answers

My HTC HD7 on/off button does not function after charging. After unplugging the charger, the icon shows still charging and the backlight stays lit. I can still use the phone as usual, but must remove and reinstall battery to turn off or sleep. I can remove and replace the battery and it is fine for 30 minutes or so then cannot use the on/off button again. I performed a factory reset, but same problem. Any help will be appreciated. Thanks

It sounds like a hardware problem, since you restored it to factory, software is probably not it. You should go take it to get it repaired.

Yep just get the power button replaced.

[Q] Help! Nexus S will not start

So here is the deal...
My kids needed a night light as we are on vacation so I decided to plug the power charger and left the flashlight app on the entire night. Now that I think about it not a smart idea.
When I woke up this AM the phone had the battery charging icon on the screen. This only appears when the phone is charging while it is powered off.
So far I have removed the battery several times and tried to power the phone on with no success.
I have also tried to hold the volume down and press the power button as recommended on various forums with no luck.
I am overseas right now (home town is the usa) and I need my phone more than if I was home .
Any idea how the flashlight app left ON while also powering may have caused this?
Or is this just a coincidence and I am having an issue that others are having and it is not related to what I did last night?
Thanks and any help is greatly appreciated.
By flashlight app do you mean one that turns on the camera flash or one that leaves the screen on?
I am also unclear what you mean by:

Does the icon appear even when not charging? Does the screen function at all? Or does the phone seem completely dead, as in not even vibrating when powering on after removing battery.
If it was the camera flash, it might have overheated and damaged something, but this is just my speculation.
By flashlight I mean the one that leaves the screen on in white color.
The icon only appears while the phone is hooked up to the charger. When I unlplug it it disappears. (So to me this answers your question if the screen works at all).
The phone does not vibrate when I try to power it on after I remove and put back the batter.
Thanks for your quick reply and hope this answers your questions.

HTC Sensation Power Button (On/OFF) doesn't work.

Hi everyone. Today i was chargin my phone at PC using a no-name usb cable. I've noticed while it was charging that the screen kept turning itself on and off. When i finaly took the phone, the screen was unlocked and when I tried to press the home button it did nothing but taking screenshots (like the power button was stuck). The power button was not wroking either.. After I took out the battery and restarted the phone, the power button didn't work at all. Tried to clean it off using this method but it did not work. Tried to clean the power off button using a method i've seen on google (can't post the link since i'm a new user) but its still not working
I'm desperate, please help
Are you sure, that the problem is only the power button? I have sometimes problems with this phone too. Sometimes you can't turn it on.
Try taking the battery out for at least one hour - then try to start it. I had always success with this.

The batter has proven me to be fcked in the last week, had lots lots lots of random turn-offs and restarts. But for more than 5 hours the power off button didn't work.
I'll let my batter out through the night.
Thanks for reply.
PS: I'm running ARHD 7.3.

The restarts can also result from a loose battery. Try putting a folded piece of paper between the battery and the upper casing of the phone, so the battery is pushed against the pins. This is a well-known issue. It helped me a lot. Before I had also lots of reboots.
Yep, did that in the last 1,5 year and the random reboots stopped. But as i've said, now it happens even tho' i have a paper that keeps the battery steady.
Lol just took the phone to see if the power button works and currently i'm talking screenshos pressing the home button .

How did you turn on your phone if the power button doesn't work?

I take the battery out, put it back in and after a few seconds the phone turns on.

Well, this isn't normal. Is your power button constantly pressed?
Try the following: Hold the volume down-button while inserting your battery until the phone boots up.
Does it boot into the boot manager?
Just woke up, plugged my battery in and the power button worked almost normally. Could've pressed it 5 minutes and after that and a restart it didn't work anymore.
This means I should buy a new battery and everything is fixed? Are the Anker batteries worth it ? Or do you recommend me a HTC EVO 3D battery ?

You can use the battery from the Sensation XE, which has 1.700mAh instead of 1.520 (or 1.560). At the HTC-Store they are about 50 € here in germany.
Always buy original batteries! Not the cheap ones from eBay. They usually don't have a temperature sensor, so the phone can't shut down, when it gets too hot while charging. This can be very dangerous.
I haven't got any experience with Anker-Batteries - sorry.
Pressed the volume down button and it got me into the boot menu (just like the power button is kept pressed).
Do you think that if I change my batter it will fix my problems ? Also noticed that my battery is altered, aka its not flat but swollen.

If it is swollen, it is definitively broken. Mine had the same symptoms...
I'm pretty sure, the powerbutton-problem isn't related. Does the button feel normal, if you push it? Or is there no "click"?
Maybe you can repair it with a needle by lifting the foil a tiny bit.
i dont think you need a new battery, same problem occurred with my phone, done some DIY fix and written that in a post for fellows like you in search of help.
here is the link to it:

A new battery has fixed it.
No problems with the phones until now. It works perfectly

Unbelievable!!! Thanks for the link above - it worked for me, the power button is fixed...

[Q] Battery logo only

I've been searching for a while but can't seem to find anyone with the same issue. When I insert the battery into the phone I get the empty battery logo then the lights under the touch buttons turn on and then the screen and button lights turn off and that's it. No looping. If I pull the battery and insert it I get the logo and lights and then nothing again. I can hold down both volume buttons while I insert the battery and get to download mode. I can then flash back to stock and reboot into the rom but as soon as I reboot from the rom I'm back to the empty battery logo and then nothing. I've replaced the power button but I'm pretty sure it's not a button issue. Any ideas?

Dont do anything on the software side, it is a hardware problem.The power button is broke.
Get it replaced or open up the cover and blow air onto it... there is a guide to show you how.

If you are able to flash back to stock, in the stock rom, try reseting the phone under "privacy" then boot into recovery and factory reset the too.
If that doesn't work, make a video

Turns out my USB connector was faulty. I removed it from the motherboard and now when I insert the battery nothing happens like it should. I can now turn on the phone with the button. Guess I'll be ordering a USB connector off ebay.
Worked for me as well

The same thing happened to me. After reading this tread, I replaced my USB port and its perfectly working fine again. I can get into Recovery and everything now. No random reboots and things .

Xperia Z3 wont turn on

Hello,
Last time i saw something on my screen was my battery that was almost empty. Now when i want to charge my battery i can't see annything on my screen.
I only see a red charging led light left top of my phone.
I tried several tricks like power button and the sound buttons up and down combinations. even the yellow little button near my simcard.
I could get the 3 vibrations but i still see nothing and it won't turn on?
I Even try with the sony pc companion but it won't recognise my phone even with the volume down button,
How can i Solve this problem ?
3 vibration mean you're turning off you phone. When you do that, just plug in and let the phone charging. It'll take a while, when your phone show battery percentage just press and hold the power button again. It might work

Boot loop after rooting MMB29V. Please help.

I was running the latest stock image (MMB29V) since yesterday on my Nexus 5 and today I used the Nexus root toolkit as always to root the device. Well TWRP flashed once and it said it copied the root files to the device. I had it in my pocket for a few minutes and after that it went into a crazy constant boot loop. It will stop eventually but if I keep the charging cable in it won't stop. I cannot get into recovery because I get the "Start" screen but I cannot advance because it reboots too quickly. I have found a few you tube videos where people push the power button like they are playing the old school game "Track and Field" but this does not work for me nor do I think it's a power button issue. I think I stupidly might have hit some kind of button combo while I'm my pocket believe it or not. I pulled the cover off and was hoping to pull the battery but Im not a fan of doing that since its not a simple task. Any help appreciated. This phone is dead to me and that is NOT good. I need to get this working.
TIA
Bill
Will the phone stay in fastboot mode or does it quickly restart?
Possible power button problem?

It quickly restarts. I want to say its not a problem with the power button because it has been fine for a few years now w/out issue and only happened after rooting earlier today. Right now the only way I can even get the phone to turn on is the plug the charging cable in and then the restarting commences. Does it sound like a power button issue? Possibly but its hard to believe, I dunno. Waiting on a call back from Google tech support to see if they are any help.
It could be a power button issue. You'll have to remove the motherboard to find out.
Once removed from the housing, quickly press and release the power button several times in a row using more pressure than normal. While the motherboard is out of the phone, clean around the power button with pure alcohol.

Did NOT want to screw up my phone so I sent it to LG. Took a few weeks but it cost me 78.00 total for them to repair the power button issue. Whatever they replaced also fixed the low volume issue I was experiencing as well so it worked out.
