Computer reset and now phone wont turn on - EVO 4G General

I was changing the frequency of my video card and the screen went blank and I had to reset my computer. After resetting my computer I looked at my phone (which had been plugged in and charging to my computer) and it was off. When I tried to turn it back on the screen flashed for maybe half of a second and went back off. I am using a HTC EVO 4G rooted with gingerbread 2.3 ROM

Sounds like for whatever reason, your battery may be completely dead. Maybe something weird happened when the computer reset...I'm not sure. Do you get a charging led when you plug the phone into the wall (A/C) charger? The USB from the computer isn't strong enough to charge the phone when the battery is completely dead, so you need to plug into the wall. I would charge it up for a while, and then try to turn it on again. If you don't get a charging led at all when you plug it in, I would try a battery that is known to be charged up if you have access to one. Good luck.
It also wouldn't hurt to try doing a battery pull.

It was dead when I first plugged it into my computer and then it started charging. I plugged it into the wall and it still wasn't turning on and wasn't getting a charging LED. I left it on the wall for about 15 minutes and nothing still, right now I have my battery in the freezer. I read somewhere putting your battery in your freezer could fix it or it could be completely wrong.

Take it out of the freezer, leave the phone alone for about an hour then but the battery in and plug it up. When the led light comes on, don't turn the phone on just let it charge. This has happened to me a few times and I thought I screwed something up but I did what I just told you to do and when the led light came on I let it sit and charge and then turned it on in the morning. I think the battery discharged somehow (guess), good luck.

Yea, I'd put it back in the phone and plug it back in. Let it sit for a while, an hour or two. If you don't get an led in that amount of time, you probably won't get one. You can take your battery to sprint and they should be able to boost the battery and bring it back to life.

so strange, i think this is not a fault of battery, because lithium polymer battery is really long lasting, have you connect your x1 to computer, please connect your x1 to charger and wait about 1 hour. but maybe it's the fault of mini usb port, can you sync your x1 before it happen? in your case, bring it up to guarantee service is the best solution, what did you do before the device turn off?
Leave it on the charger, it could take about 15 - 20 minutes to start charging if the battery completely died.
i used a wall charger, and a computer charger, still no luck...i wasnt doing anything, i was playing a game and shut the game off started browsing through the fone, and it just shut off after a few battery low warning sounds. but the red light goes on after a wall charger, but nothing when i try to turn it on, it doesnt turn on, and when i unplug it to try to turn the phone on, the side lights flash red...i have no idea whats goin on but i got the phone today and its pissing me off already i spent 680 on the phone for a peice of crap...

ah, you should keep it in the wall chager a bit longer, and don't use the computer charge at this time, when the battery complete die, you should keep it charge about 10 minutes before you can start it, don't worry, when you can see the flash light turn red, it's charging, wait a few minutes more, it's will work, just forget about it, go somewhere, when you comeback, push the power button:d

was had same problem.just leave it charged.i leave it charged into usb drive,and it needs 5h before he turn on.battery was completely dead,like probably you have too.just leave it charged throught the night.
Charge some time and then remove battery cover and try to reset. as u mentioned lights are flashing when u r trying to switch on so just reset.
The X1 of my colleague had the same problem and he had the battery replaced by the vendor, no questions asked as it was dead after only 2 days...
Charged without battery...

Hi, I got similar problem and I called the support guys.
They advised me to remove the battery and charge the phone for 30 min and charged with the battery for 1.5 hour.
He claimed is some 'internal battery' stuffs.
Anyway I tried and it works.
In addition, I charged the battery when the level hits a minimum of 20%.
So far so good
Good luck.

That Solution worked for me as well. I was in Germany with some navigation software to find my destination address. Than suddenly my phone died, I thought. So I was stuck somewhere in the middle of nowhere.

Ummm Worried... phone wont turn on...

I was running Fresh 2.0d for about 2 days and everything was working fine.
I was in the middle of testing if bambuser stream app was any good and it just...kind of died.
The battery was at 0% basically but I had it plugged in to the comp. The phone's charge light it turning on but the phone wont power on...
Help?
Don't panic. It is just "shot" as I call it. Needs time to charge and cool down. I would recommend plugging it into a wall charger is possiable. Pull the battery out first though and pop it back in. Then put it on the charger for 15 mins. I promise it will come right back on (I have this problem when tethering for days on end LOL)
Yeah I was hoping I'd get a response like this... cause the charge is functioning... its just not turning on
But yeah it WAS at 0% so its kind of stupid to make a topic like this.
HAHA Well I understand the worries. When this 1st happened to me, My heart sank and I died inside xD. I could have swore that my company busted me tethering or something and turned off my phone LOL I didn't know.
Can't live without tethering
There's actually a warning from HTC out there somewhere that says if your battery is below 15% then you shouldn't try charging via USB. But yea as others said I would get it plugged in to a while and be patient. It'll come back to life.
Lol, this just happened to me today too, was testing out the new aloewishus rom, and while booting it went blank, then just... stayed blank. Took batery out, put back in, it'd vibrate then... blank.. Luckily i had a back up, fully charged batery, popped it in and viola! works again, I was super freaked out for a minute.

*takes out of comp and puts in wall*
Yeah I'll charge and check it out in the morning. Gotta get up in 5 hours...
this happens to me all the time. all you have to do is unplug the cable from the phone, push the power button and plug it back in.

Flipz is correct, and I had this happen to me before, even the car charger wouldn't help, I had to wait until I got home and plug it in the wall charger and *poof* it turned on within five minutes of charging (BTW: when it did boot back up the battery was drained 92%)

USB ports can't put out as much current as the wall charger can, so it will charge MUCH slower via USB. If you're running any power hungry apps, it's entirely possible that USB won't be able to keep up and your battery will go dead even though it's plugged in.
In fact, I've noticed on a couple of CPU intensive games even the wall charger just barely "keeps up" (meaning the battery doesn't drain, but it also doesn't gain any significant charge while I'm playing them).

[Q] Dead Battery Issue

So I thought I had turned my phone off last night because I left the charger at work but apparently it did not shut down and the battery died. I know that MAGLDR doesn't allow charging while the phone is off, does anyone know a way to get enough of a charge to get the phone to turn on so I can charge it fully?
I can charge in MAGLDR, just the orange light sticks on and will stay on until you pull the battery. Try giving it a few minutes just to get some charge in it, pull the battery, turn on and start the booting process, then plug the charger back in, works for me on NAND builds, did it last night even whilst calibrating my battery.
Ok I will plug it in and leave it for a bit, the orange light shuts off after a few seconds but we will see what happens. I was always under the impression that MAGLDR didn't charge

That's correct, magldr won't charge.
Another solution I saw a few days back said to go into Bootloader and charge from there - just tried it as an experiment and unless it charges without activating the charging light, Bootloader doesn't charge either.
When I had a similar problem I just kept booting it up into WP7, allowing it to charge for a few minutes until WP7 shut itself down again and then pulling the battery to repeat.
It took 5-10 cycles of this but eventually the phone decided it had enough battery to charge itself - seems daft to me too, but there you go.
If all else fails, search this forum - there was thread from a week or so ago where someone chopped a USB cable to charge directly to the battery terminals. A spare battery is also an option if it fits your wallet and timescales.

Battery icon has yellow triangle and thermostat icon

Hello all,
I left my phone charging over night as usual. When i woke up i was surprised it had only 32%. I plugged the charger back in, but the phone wouldn't charge. I restarted the phone and when it booted up it had 60%
After some standby time it showed 50% .. really confusing. I pulled the battery out and when i plugged it back in and "before" turning it on. The green battery icon came on flashing with yellow triangle and red thermostat (see pic).
It won't boot up until i plugged in the charger. I left charge until 100% and tried to restart. I got the same icon again and had to plug the charger in.
Anyone know the meaning of this? Battery app showing temp as 36C after boot up. Now it shows 34C. I did attempt battery stat wipe too.
Please share with me your thoughts.
EDIT: I returned mine for a replacement. After that, my nephew admitted that he spilled something right over the usb.
I had a similar problem. When the icon comes up plugged in, yank the battery out and shove it back in.
If that doesn't work, when plugged in take the battery out, unplug the phone, put the battery back in, and then plug it in.
It worked for me!

HEY!! that worked for me. Thank you sooooo much
OK guys, it came back again. The issue is not resolved. Perhaps a battery failure?
I waited for my battery to completely run out. Then charged it all the way up. Then a simple battery pull out and in takes it down to around 80% ?!
Strange stuff here.

Sounds like a very delicate procedure xD
it seems i am the only one with this issue :/
Sounds like the battery just isn't being calibrated correctly.
Let it drain fully and then take it out and put it back in. Chances are it'll turn back on. Let it drain again until it shuts off and then charge fully while the phone is off.

Same problem here. The phone is "charging" even without the charger plugged in (!) When I turn off the phone a green battery icon with a yellow triangle and a red thermostat is flashing. Can't turn it on without a charger plugged in Tried everything. Anyone else suffering from this?

Probably your USB got polluted or bended.
i also think it is a usb issue. i updated the original post. By the way before i returned it for a replacement i tried using a qtip and "contact cleaner" and sprayed some on the usb. After 30 mins i was able to charge normally before it was acting up again.
Bottom line: clean your usb.
Cheers a bunch for your replies! Gonna clean my usb again & carefully "bend" it down a bit. I'll post the results later
Hahaha I laughed so hard in a bus after reading your edit. What a cute nephew
I feel sorry for you though
Tried everything, including a couple of factory resets/wipes. Sent it to the service center yesterday
For me the main idea from using SGS2 for cpl of weeks before selling this crap:
'Do NOT buy korean smartphones !!!'

I cannot disagree more. This is the most fantastic phone I've ever had. Feel free to check my signature. I've had worse. Haha. Much worse. This phone has only lagged twice in the months I've had it and I had to do a battery pull once. I've had my iPhone 4 crash more times than this phone.

I've had charging problems with my SGS2 as well. All of a sudden it started switching tap&talk on and off. Turned very warm and drained the battery juice.
When I attached the charger, it didn't show signs of recognizing that it was attached. I tried to switch it off, and on again with cable connected. Then it started charging, but if I unplugged and tried again it failed again.
So I had to send my beloved SGS2 for service. Now heading on to two weeks without it, i'm growing desperate from having to spend the time with my old Samsung Spica.
Have a look at the charge port problem thread in general. Few of us have had this problem for various reasons.

i also have a kind of similar problem on my S2, suddenly it stopped charging, when i plug it in i tries to start up but isn't able to & then restarts.
i get the normal battery sign when you plug it in after the battery completely dies (no thermometer), nor does the phone or battery gets hot. is there any solution or should i just take it to a service centre? BTW my phone is rooted & loaded with a custom ROM.

[Q] Mytouch 4g died in sleep?

So, this phone was working without any problems but then my wife turned it off and left it in the drawer for about 3 weeks when she went overseas. When she got back and tried to turn it on it wont turn on. We figured it might have drained the battery so we plugged it in but now its not charging either! When I unplugged and plugged in, the LED blinked orange once but now it wont even do that either, no power, no LED, not charging either. I have tired everything, left it disconnected, battery out for an hour, then put it together and tried to charge, still nothing.
Any ideas? It is already out of warranty so talking to T-Mobile is out of question.
Nothing has been done to it, it is physically fine, it was just off for a long period and not it just wont respond.
Edit: Fixed it! I don't know what, I was almost giving up, but I took the battery out and blew hard on the battery contacts in the phone and in the charging port then plugged everything in and put it back on charger, orange light started to blink and then went solid and now its charging. I just turned it on. This phone is dodgy, no other phone hard bricks like this if you leave it off.
Some phones don't function with completely discharged battery. Actually, most of newer phones. You need to leave the battery inside and the phone connected to charger for some time, till the charging light shows up. MT4G is very far from being "dodgy", doesn't differ from many other phones that behave the same, and you were nowhere near "hard brick".
Good luck in powering up Motorola Defy with completely discharged battery.
Recoverable problem

Had a similar problem. Phone died while using it then wouldn't light up when plugged in. Left it plugged in for half an hour wouldn't seem to charge via wall or car charger. Tried doing a hard reset with/without the battery & plugged in/not plugged in in various combinations. Got nuthin. Drove around for hours looking for a replacement or open T-Mobile place, until it got too late and I went home. Live chat with T-mobile rep was a waste of time. Plugged it in the wall and left it, as this once brought back a G2 battery that I thought was cold dead. Five hours later it was lit up and charging, showing 40% charge on the battery indicator app once I turned it back on. "HTC Sense" crashed immediately on boot then recovered. Seems to be fine so far.
- Suggestion; plug it in and leave it overnight if it seems cold dead and doesn't appear to be charging. It seems to need to hit some critical threshold before it will work again (as indicated by previous poster). Also pick up a couple spares off amazon or newegg if you don't have a second phone available.
