red ! on my battery

OK, so I put my phone through the wash the other day. I took it apart and let it dry out. I turned it back on and it works like normal except some screen tearing/wash and theres a red ! on my battery indicator. Not sure what that means, the battery isnt low, and it wont let me charge it (doesnt recognize wall or car charger) I switched to a different battery and it didnt change.
Any ideas??
Also, if I take the screen apart to try it out even more, do I need to reglue it??
Thanks

Thats the water mark indicator. There is also one by the usb port if you take the phone apart.

I would take the battery out of the Evo, and let both the Evo and battery dry out for at least 48 hours before assembly. Can't rush the drying process, except maybe with the help of a hair dryer..........but not too hot
In addition, this may help you out >>

Yes, this. Its the screen one, not on the actual battery.
And theres no triangle, its just red with an ! in inside of it.

so does anyone know how to get rid of it??

In my experience it means your battery is shorted. Replace it, or try someone else's battery and see if it goes away.

I'd still let it dry out, and Don't put the battery in for a couple of days.

And for gods sake do NOT use a hair dryer when a phone gets wet. All your gonna do is cause corrosion. Put the phone in a zip lock bag with white rice and let it sit for 24 hours. The rice absorbs the moisture. With a hair dryer your moving water throughout the phone and heating the soldering joints at the same time.

For an initial drying out, the hair dryer, as long as it's not too Hot......warm to cool, should be ok. Even cool is fine. It is that the rushing air gets into the device and removes some of the moisture. Nothing to do with the heat really.
But the rice in a Zip Lok is an excellent idea as this was the case years ago with questions regarding getting the Diamonds and Touch Pros wet.
This may help you out.
May just need a reset, no matter how dry the phone gets >>

Dont wanna create a debate but Ive seen so many people come into my work that used a dryer and caused more damage than the water itself caused.
"Even on cold, it can put out enough heat to potentially damage your cellphone. It also can cause static electricity, which is a big no-no for anything that uses computer chips. So do not use a hair dryer to dry out your wet cell phone, no matter how exasperated you are."
Hair dryer is bad news all the way around.

Ok. So ere on the side of caution and don't use a Hair Dryer.
I used one a couple of times years ago without issue. I used the dryer (only a few minutes or so on cool) as a prelude to Air Drying and it helped to resolve my issue. I should say my issue was resolved, whether it had to do with the hair dryer or letting the device just air out, or both.
In the cases you have seen, we don't really know for sure the circumstances of the procedure used regarding blower air temps, etc. But as I said, a resolution can probably be achieved without a Hair Dryer.
If you feel the device is Dry, see the above link and see if a reboot works for you.
If you don't feel the device is dry yet, try the rice in bag idea.

Time for an insurance claim. The store won't touch it if it's been wet. You could always try the rice method if all else fails, or as a last ditch effort before dropping 100 bucks with insurance.

+1 on the rice. Works like a charm.

Well a little update. I tried the link, when I try and use fastboot to power down, it restarts, so I cant actually power down and then take the battery out. But as far as the screen goes the washing and tearing is completely gone, you cant even tell its been through the wash, it looks brand new. I didnt even take it back apart, I just kept using and it seemed to dry up by itself.
Any other ideas as to how to get rid of the ! ???

I just followed the link I gave you previously>
- Put your device in BOOTLOADER (You know how to do this :
--Power Off and Shut Down the Device. Press Vol Down, and press Power Button while still holding Vol Down. Let the device go into BOOTLOADER
--let the device do its thing for a few seconds
* After you entered Bootloader Previously, you were probably in the screen that said:
HBOOT
<VOL UP> to previous item
<VOL DOWN to next item
<POWER> to select item
FASTBOOT
RECOVERY
CLEAR STORAGE
SIMLOCK
HBOOT USB
(There is No Power Down in this screen)
After you see the above screen, Press the Power Button ONCE. You will then see the following screen:
FASTBOOT
<VOL UP> to previous item
<VOL DOWN> to next item
<POWER> to select item
BOOTLOADER
REBOOT
BOOTLOADER
POWER DOWN
After you see the above screen, toggle the Vol Down button until you Highlight
POWER DOWN
Press the Power Button, and the device will power down. Wait a minute or so.
REMOVE the battery at this point, leave it out a minute or so, put battery back in, and Power Up.
See if the Red Explanation Mark is gone..............

You could also disassemble [at your choice] since you seem to want to, but let the parts in rice.

Screen Switches On/Off Continuously

Since a week ago my DHD screen started switching itself on every few minutes. The phone doesn't unlock but keeps lighting up which is annoying esp at night! I'm using stock 2.2.1 Sense so can't understand why this started happening. Reset or removing battery doesn't do anything either
Anyone else had this or found a solution?

I had a similar problem with my HTC Desire. I found it to be a problem with the power / lock switch on the top of the device that was getting 'stuck'.
Can you confirm if what your experiencing is the same as if you were to continually press the power / lock button on the top of the phone?

Yes, it's basically the same as the power button being pressed. I wondered if it might be stuck but it doesn't look any different or stuck..

Just out of curiosity, could the phone have been exposed to water at any point?
It's indicating to be a hardware problem since you have the Somebody on HTCPedia.com was having a similar problem and this seemed to solve their issue:
I had the exact same problem and it was (most probably) also caused by exposure to water: I had the phone in my pocket while cycling through rain and it all got wet. Since then, the power button got stuck, as in it was always pressed but sometimes was getting released depending on how the phone was held. For me, this resulted in the batter being drained in about 4 hours since it kept bringing up ShutXP.
EDIT: Do not use a flux remover (de-flux) solution/spray like I described previously (now deleted). In my case it worked for about 1 day and then then button was completely irresponsive which is a worse problem than having it always pressed (if you take the battery out, you can't turn it on).
I was inspired by a solution in another forum. I used surgical alcohol that yuou can by at any pharmacy. The higher the concentration, the better (I used 90 deg).
Take the battery out first !!!
Effectively, you drop a few drops of alcohol inside (yes, inside!) the phone through the small cracks around the power button. I used a pipette but dipping cotton in alcohol and then squeezing also works. Don't worry about dropping to many drops of alcohol ... it dries very quickly. I then blew in- and shook the phone strongly (this was important) to make the liquid advance a bit inside and also to dry it. You then need to leave the phone to dry. You can speed that up if yo put it under a desk lamp.
All solved now. Power button now works fine. What happened probably was that humidity/water created a short circuit, giving the same result as keeping the power button pressed.
If the above doesn't do the trick, you can try to unscrew the plastic shield that covers the button, remove the external button and access the real micro-mechanical button that is soldered onto a very small pcb. You give that one a good clean, rubbing it generously with a small piece of cloth dipped in alcohol. You can also try scratching the surface between the button's soldered pins since that's where a short circuit probably formed in the first place.
Hope you fix it.

Hope this helps

Thanks a lot for the help. This is why xda is such a great forum. From this I worked out it is the power switch and after playing with it and seems to be working on for now. If the prob happens again I'll try the alcohol trick above.
Thanks again

My money is on a hardware failure. Do you have a stock ROM ?

hey yea i went and unrooted and reinstalled my carriers stock ruu....still same problem.looks like taking it back to the shop for them to fix

Hey actually exactly one week ago my Desire started the same exact thing, and I could not find help anywhere. Best info I can find is that it might be moisture, but at least for me I don't think that is the case.
I ended up taking the whole phone apart (been taking stuff apart all my life, but i was still nervous) to clean it out since I've had dust in the screen for a while... I think I cleaned it out pretty well, but did not take the plastic tape off the button. This did not immediately help, but after playing with it for a while it now works most of the time, but is quite sensitive usually.. the button "presses" before it mechanically "clicks".
Anyway, If you were to become desperate enough to try this, I would recommend pulling that black plastic tape off the button when cleaning, then stick it back on. Good luck
I've been lusting after the Sensation anyway

yea im not into pulling stuff apart that i got no idea about...took it back still under warranty n its getting sent in for repair...now stuck with a piece of **** samsung omina icon....windows phone sucks the big one very hard...ill be going back and asking for at least an android as a loaner while its in for repair

ohh well that's good that it's still under warranty. I was actually using the camera at a beach during hurricane Irene and that night the power button went berserk.. continuously turning the screen on and off... before eventually just staying "pressed" all the time again. So maybe the moisture theory isn't all that far fetched in my case (I was at a beach the first time it happened, but never went near the water)
Currently trying to get a broken Desire on ebay to harvest for parts :/

Moisture - Htc Desire Power Button.
Hello,
I've met with that problem.
I've unscrewed the device, I've remove the black tape, and I've used a cotton swab to clear it.
But the problem was solved, but later withing the 24hrs, It's back to auto on/off without pressing the button.
I would like to know, Should I remove the yellow transparent tape on the button for cleaning?
Thanks.

[Q] Resurrected my Epic from the toilet.One problem though.

Ok my one and a half year old son got a hold of my Epic Touch and I dont know for how long he had it in the toilet.I knew this day would come but I was hoping for it to be my girlfriend's original Epic,lol.
So I took it apart,dryed it real good with paper towel first,then with air and baked it in oven for a minute or two.
I put it back together and it works!Its amazing because after my son diped it in water it layed wet for about twenty minutes before I found it.
I have one question for those that have more knowledge about Epic's internals:
Everything works except the POWER BUTTON!Yes I can use the power button one time to turn on the phone but after that it doesnt work anymore.
I cant turn off the phone,bring up the shutdown/airplane mode menu or anything else,in order to turn off the phone I need to pull battery.
Yes I took it apart again cleaned everything with rubbin alcohol inside and still same problem,any ideas?
Thanks in advance.
Oh,is there any apps out there that can map power button to search or home buttons?

Do not power it back on.. Put it in a sealed bowl and fill it with rice. Leave it there for at least 24hrs. Even longer if you want the best result. It takes water damage a couple of weeks to really rear its ugly head. Sofar rice seems to be the best bet.
Good luck.. Report back to help out others with this same prob.

Definitely try the rice trick... I would recommend doing that before baking your motherboard in the oven.
The only time I've ever heard of baking any electronic device in the oven is for the Xbox 360...

I already took it apart and dried it,plus put it in oven.I would say that there is no need for rice now,rice is for those that want to dry inside without talkn the phone apart.Everything works but the power button which is really strange.

I just did that to make sure any remaing moisture was gone.Still no answer why I cant use the power button except to turn on the phone.

Are you on a custom ROM? if so, maybe its the ROM bugging out, not the phone. Just a wild guess.

Do the RICE deal as mentioned above it WORKS on all sorts of electronics!

Im starting to think that too,im gonna try reflashing and see what happens.Power button does work to turn the phone on but after this it doesn't.
I just don't want to reflash because i been running Blazer 4.0 for 3 months now(the longest i ever went without flashing,lol) and i added all types of custom apk"s to that rom.I would usually extract apk files from this rom and pit them in the new one but i odexed it,so no it looks like im going to have to make a whole new rom and that's a day gone.

He has already gone far and above the rice trick. That would be repetitive and unnecessary.
Also, rubbing alcohol is not a good solution. It leaves a film on the metal that is highly corrosive. You need denatured alcohol.
The power button has a two step contact. That button most likely needs to be replaced. You can order cheap on a wholesale parts website.

Finally someone understands it.I don't think power button needs replacement because i use the power button to turn on the phone,lol.But after that power button doesn't work.The power button only works one time-to turn on the phone but that's it,so its not the button that's defective.Its gotta be software related or one of the chips that controls power button after the phone is on is fried.

I didnt kno the e4gt was out that long lol.. Either way anything could be going on.. It was dropped in water lol

Try button remapper to resolve the power button ordeal. I personally would ditch the search button and use that as the new power button.
Sent from my SPH-D710 using xda premium

The likely reason its not functioning after you power on is a short somewhere created by the liquid. When powered off the short is not affecting but once on it disables the button. I dont think you can replace that button unless you've got some decent soldering skills and you cant really be sure that even that would fix it. Liquid is one of those wildcards when it comes to electronics. You dont know if your screwed from jump or if the liquid might rear its ugly head later... too unpredictable.

I already thought of that,i was thinking if i run the phone for a while and internals get warm that this little drop of water will evaporate(if that's what it is because i heated in in the oven pretty good,i couldn't even touch it),i will have to see after few days of usage.

i thought the one problem... would be it smelled like ****. :good:

Lol the water emits an electrical shock when put in water which can damage any part of the phone.. Heating it up in a microwave is only resoldering the phone.. Wont fix an electrical shock that could have damaged a chip or a hardware button a led etc.. What would happen if you had a pc plugged in and dropped it in water while it was on? Just throw it in the microwave and itd be fine?

Lol,microwave?Who said anything about microwave?Im talking about regular oven,microwave will fry everything in few seconds.

Damn it,now its serious,phone wont go into Download Mode.When i try to put it in download mode i push "up" key for "Yes" and it flashes for about one second download mode,well not exactly it flashes this:
ODIN MODE(in red letters)
Product Name:SPH-700
Custom Binary Download:NO
Current Binary:Samsung Official
Downloading do not turn off target
It flashes that for about one second then it starts to boot into android.Another thing that i noticed is when i power on the phone i get Samsung Galaxy S2 logo then it disappears then the phone reboots and i get Samsung Galaxy S2 logo second time and then it boots into android.
So it boots after second galaxy s logo.I can still boot into CWM though that's only good thing.
Has anyone encountered similar phenomenon before?

Power Cycle

So after finally fixing all the other issues i had with my phone (broken screen, broken vibrate motor, broken speaker) i was finally at ease. It lasted for about a week with everything functioning until now the phone gods have again struck me down. This time i have what is referred to as a Power Cycle. Kind of like a boot-loop except the phone completely boots up into my homescreen then the power options menu pops up, and no matter if i click back or not, that **** is going to reboot on me. Its to a point where if i pop in the battery the phone auto boots. Here's the kicker though. If i take off the back case and just set it on the battery with an open back, it doesnt power cycle. But the power button on the case itself is not stuck as you may be thinking as i can depress it and the cover spring pushes it back. I've hard reset, even went back to complete stock (no root) and it still does it. the power button works (very sensitive) if you have no case on the back, but if that thing is on, it acts like the button is being pressed.
Any Ideas?

Sounds like the power button is stuck... Try taking the phone apart and cleaning the contacts. Then press the power button a few times to ensure it works like it is supposed to. Put everything back together, tighten the screws but don't torque them. Should not turn on after you put the battery back in, wait a few to make sure it doesn't. Then power it on and see how it goes.

still didnt work. i used some rubbing alcohol and a lint free cloth on it. the interesting thing is, when you take the case off, if you set your finger over where the button is (making no contact) it still registers that you are touching it. this is what i think is causing it to power cycle when the phone case is on, as it believes that it is being pressed when it isnt.

I had almost the exact same problem with my Epic Touch. Ended up being a bad power switch. How handy are you with a soldering iron? If you're pretty good, you can buy the switch for ~$10 and replace it yourself. (You can also try cleaning it - several tutorials here, and the "Captivate" phone seems to have the same switch and issues. Search both forums)
Several eBay sellers sell the switch you'll need.
