MT4G Turned Itself Off & Power Button Won't Work

Ok.. so this is the second time this has happened..
My phone was fully charged and for no apparent reason turned itself off. Then when I attempted to turn it back on, the power button would not do ANYTHING at all.. even after multiple presses (like 20).
I plugged the charger back into my phone, and the light wouldn't even come on indicating that it was connected to the charger.
Finally pulled the battery, put it back in, and viola - it powered up.
Then I was talking to my buddy and the same thing has happened to his MT4G. Except he never pulled that battery - but he said it took 15 minutes before the power button worked.
I think this is a BIG problem, because when I started searching the net for similar situations, I found one.. with the G2. Now that's TWO T-Mobile phones with the same problem.. Both made by HTC.. both with several Quality Control issues
Anyone else have this problem? I'm starting to think about going with a different phone now, which is crazy because I was absolutely in love with this phone... but I am not about to have a phone that decides to shut itself off and won't power up. Especially since my friend has the same problem which tells me this isn't something specific to my phone only which means potentially any device I get can have this issue.
I was deeply saddened to read the G2 has the same problem. What's going on HTC????!

Are you rooted? Overclocked? It really sounds like phone couldn't handle amount of OC (which happened to me several times). However, if it's a stock phone - hurry up and bring it back to T-mo and ask for replacement. This is not a common issue for these phones, first time I hear about it. Of course, there always will be cases of QC but, once again, this is not a common behavior.

I can say this has never happened to me so it sounds like an issue with your setup. Do you have anything modded ie overclocking is the one I'm thinking. Maybe pushing phone to hard.
Edit: sorry just realized I was in the general section.

No, I am not rooted. Stock running Launcher Pro Plus and Live Wallpaper.
After checking around, it appears this has been an issue for many G1, G2 and even a few Nexus Ones.
It appears the general consensus is that either the contact pins for the battery are not making firm contact when the battery shifts (supposedly on some phones the battery prongs not protruding enough, I have not checked mine yet but I intend to shortly)
I really don't want to return my phone.. my screen is the good one and my FFC is centered..

This happened to me just an hour ago. Only had the phone since friday and had this happen for the first time. Wouldn't respond at all. Everthing stock on phone.

Well I would return it because you chances of getting another good one are pretty good.

Yeah, but what are the chances of getting one with the good screen, a centered FFC and no gaps in the metal bezel/side of the phone?
I'll wait it out and see what happens. There's always the warranty.

Same thing happened to mine. I took it back. It wouldn't charge and the power button didn't work.
I pulled the battery and it still wouldn't cut on or charge.
Phone was stock.
It magically came on by itself 5 minutes later without me touching it.

Venue Pro Not Turning On

Even after reading all the horror stories about the DVP, I just purchased a new DVP off eBay. All stickers were on and box sealed. After charging for a few hours I go to play with the beautiful piece of hardware and it just stays on the dell logo. After that, the screen would not come on after doing a battery pull. Tried doing a hard reset using the power, volume down and camera buttons but still nothing. Really sucks as this is a great piece of hardware. Will call Dell Monday and see about getting a replacement. Want this to work...

My only thought is to unplug the phone, leave the battery out for about 30 seconds, and then put the battery back in. It should boot after that.

Tried that. Still no boot. Never had this happen. Gonna call Dell and see about getting a replacement.

Thanks. How long do I have to press the power button? Mine does not seem to turn off unless I remove the battery.

Thanks - sounds like a different problem, unfortunately. Hope you get your replacement device soon!

Thanks for the suggestions and replies. Dell is shipping me a new DVP in 5 biz days and I will mail the faulty unit once I receive the new one. In the meantime, I am going to continue to see if I can get this one to work.

My wife's venue pro had this problem. Unplug the phone, take out the battery, plug the phone in without the battery for a couple minutes and see if battery symbol shows up or it boots up. Then insert battery. Has worked several times here.
'
'Note: must remove both battery and cord first, then after 30 secs plug back in w/o battery.

Was about to suggest the same thing. I've seen this fix a friend's phone.
Pull the battery, plug the phone in, then put in the battery, power on.

Does the computer recognize it?
Sent from my HTC Glacier Sense 3.0 using xda premium

If you're talking about no power at all, it doesn't sound like a software issue. It sounds like an electrical issue.
If the screen backlight comes on when you hit the power button, then it could be software or electronic (borked chip, broken circuit board, etc)
Plugging it in, even if it's a dead phone, should still charge the battery if the electrical circuits are good. The LED will come on at orange or green and that should tell you if there is physically electricity running through the circuits.
If you get nothing, something in the phone died. I'm starting to realize the MT4G has a pretty poor build quality.
If the battery is charging and the backlight comes out, maybe a quick vibrate to indicate charging, then you could have some kind of an electrical short in the circuitry somewhere.
Or you just have a bad power button. That's a possibly. But that's odd that it turned itself off. That's what makes me think the power button itself isn't what's wrong.
In all cases it sounds dead. If you can't get to the recovery screen there's not much you can do.

no led lights it just died lol... it wont do a thing. im starting to think that it has some kind of short between the battery and the circuit that distributes power through out the phone.. thats my best guess.thanks

You can also check to make sure the battery isn't the problem by removing it and plugging the phone in. Again, the best you'll get is a brief flash of the backlight. But if you don't get that, you can be sure the battery itself isn't the problem.
Or just put a new battery in and see if that works.
This is highly unlikely to be the cause. But it's all about narrowing the possibilities. I've been fiddling with electronics for 20 years now. One thing I'm sure of is that you should never discount the really unlikely source of a problem. It won't usually be the answer, but every once in a while something you'd just never suspect ends up being the culprit.

I had the exact same issue, earlier this year. Your emmc chip gave you the bird. Go into Tmobile store, tell then your phone won't turn on, you tried the normal tricks, but nothing works. Act a little dumb with them,I did that an got a new one under warranty for $5, came in the mail the days later. DO NOT MENTION ANYTHING BOUT YOUR PHONE BEING ROOTED. If you do, your gonna have to pay full price for a new one or though the issuance company a $130(or whatever your deductible is).
Trust me on this, it works. I'm still using the phone they sent to me back in June.
If I helped, give thanks(via the button )
From my fist to your face, enjoy!

Well, my Nexus 4 lasted a month.

Went out yesterday afternoon with some friends, had about 80% charge on the battery. Probably an hour into my night, I went to check my phone (i always keep it in my front pocket), and to my confusion, it wouldn't power on. Okay...maybe somehow an app left running killed the battery (although I think they designed the phones not to do this). Fast forward about 4 hours, when we get back home. I plug the phone into the wall charger and instantly see an unfamiliar blinking red led light just above the charge port. The phone wouldn't power up, decided to check back later. 30 Minutes later, still nothing. 8 Hours later on charge, still nothing.
I've tried hard resetting, I've tried holding the power button for 30 seconds, I've tried holding all three simultaneously. I guess it's just a dead phone.
I didn't root the phone, I didn't custom-rom the phone, no 3rd-party kernel...nothing...she was completely stock.
I called google, their support agent wasn't familiar with the phone. Said he'd get an RMA started, would email me the details he needed from me...never got back to me. I'm pretty pissed.
Waiting 5 weeks for a phone that dies in a month....not a happy camper.
UPDATE! FIXED IT
Following the guide here:

I took it apart, disconnected the battery lead, and reconnected the lead...poof it boots!!

UPDATE #2
The phone "died" again. Took it apart again, pulled the battery, again. Factory Reset, the phones been on a charger since then and it is still on, we'll see how it lasts the day.
I'm not sure if there is any proof of this, but I read somewhere that benchmarking apps can cause this(?) I had Quadrant installed on my device shortly before this happened. Anyway, I'll let you guys know if I have any more problems.
UPDATE #3
I've lost it again. I don't know what to do at this point...

Before I proceed,
1) Are you comfortable working on electronics
if yes, continue to 2. if not, stop here.
2) Do you have the appropriate tools?

Yes and Yes, but I don't want to void my warranty on such an unknown problem. I'd rather see it replaced and they can research the problem on my phone and try to prevent it in the future so others don't have to go through this. Thanks

Don't you just hate the fact that some random employee at Google will easily have access to all of your personal data left on the phone?
Oh well, at least you get taken care of.

I'm not aware of any warranty/void stickers on this phone.

have you seen this?

If
If the phone battery has been discharged too far then it becomes dangerous to try and recharge it as it can explode, this is why these sorts of safety mechanisms kick in sometimes.
Your only option is to send it back, if the battery safety device has been activated, it will be permanent and can only be fixed by a new battery

Are you sure? Can anybody else verify this? What were you going to suggest doing? I'm having lots of complications with the RMA process because i'm currently visiting in England until the end of the month and then I'll go back to Germany where I'll be living for the next ~7 months. I got this phone last month when I was visiting home in the US. It's a total disaster and if disconnecting and reconnecting my battery is all I need to do (and I won't void the warranty), I'd prefer to give that a go.

oh and another thing...when I connect the phone to my laptop, the USB connect/disconnect sound plays every 5-6 seconds. So it seems like the phone is turning on, and then off again...over and over again.

I figured that all this red light stuff could be solved by a simple battery pull, but LG was too STUPID to realize that people need an accessible battery and now to even try it, you have to open the phone and unscrew the battery connector.

There you go. You've confirmed the fix.

HI EVERYBODY.
I'm back. The phone has done it again. I've not got the patience to peel the back off, but it's gone into the blinking red light on charge/not booting up at all mode.
GOOGLE/LG, IF YOU'RE READING THIS, Send us all a new battery as well as the tools to replace it, and update the software, too. I'd also like $50 for the trouble, and please, fire every single "support technician" that thinks the sim card is behind the battery on a nexus (I've had that 2 times now from support)
The phone is great when it works, but it's "infrastructure" is absolutely god awful.
Will report back. Recommendations are welcome!

Nope, I haven't done that. I just took it apart and reconnected the battery for the 3rd time. I really don't know what the f**k to do at this point. Does anybody have any idea what could be causing this? Google will not allow me to RMA the phone because I bought it in the US and I live in Germany (they won't ship it to Germany for some **** reason).

not sure what that tells us, but I'm happy!

I'm 90% sure all of these weird battery problems + red light are because of stock charger!

Somebody should compare the LG charger with another good quality charger, a Samsung or Nokia for example, using a scope.

Dead DHD, I supose this is goodbye... :(

I went bowling during weekend and my good old DHD just went off out of my shirt pocket and landed flat... even the silicone case didn't help, because it just wouldn't turn on anymore. When I connect it to a PC, it recognizes HTC phone and disk but orange light doesn't light up and power button does nothing. I suppose there's nothing I can do, if anyone has any ideas, you're welcome, but I think it is kaput
What would my fellow DHD'ers suggest for my next phone? Really cool new phones like Droid DNA and Nexus 4 aren't available in Europe and Czech, so I figured either One X or Galaxy Note 2. Any other suggestions?
Cheers, I'll still be on XDA in Nexus 7 forum anyways, but I'll really miss DHD and JellyTime...

try to hold power button while inserting the battery.

Thanks for the tip, but no go...

It's sounds funny but could it be possible it fell on the corner where power led and power button are located? :laugh:
If PC recognizes it, then it's not dead.
I would try to dissasembly it and shorten power button contacts to see if that's the case.

Please try that, your DHD deserves it.
That old girl has a lot to give yet.
With the 4.2 ROMS out there is obvious that HTC betrayed us discontinuing support for our phones, and releasing less powered phones with ICS by default.

Maybe it's just the screen? Seriously dude, I would at least play with it just to see what's wrong...

It is not the screen since the orange light doesn't lit up when I connect it to the charger. I suspect the motherboard cracked, but who knows. As you say, I have nothing to lose, will try opening when I have some time...

Sadly I don't have any tips for you, but I moved on to the note 2 and while plastic took about a week to get used to size was only a problem for the first couple of minutes. Speed wise its the first phone I haven't found the need to root of flash custom rom to speed it up (I still did it for the fun). Long story short I would highly recommend it.
