Is it possible to fix the power button? - Captivate Q&A, Help & Troubleshooting

My sons captivate has a problem where the hardware thinks that the power button is randomly being pressed when it isnt. I determined that it wasnt the outer shell by dismantling his phone and putting the battery in and it came right on without the button having been pressed.

I just flooded the switch with isopropyl alcohol which ended up cleaning it up so now it works.

captivate problems

my volume down button is constantly trying to turn the colume down have taken it appart and reset it and still wont stop
Have you noticed whether or not the button seemed to click down properly (mechanically), or was it stiff or what?
Seeing as how the volume down button is actually soldered directly to the main logic board, I'd say if you don't have crud that's worked its way in to physically depress or cause the button to stick, then it's probably a broken switch inside the button (sorta like adhesive switches/buttons going out), and the only way to take care of that issue would be to replace and re-solder in a new switch.

[Q] Power button long hold- Menu is gone!?

Like the title says... holding the power button does not produce the "Shut down, restart etc" menu anymore. It locks the screen just fine and dose force feed back upon long hold but no menu pops up...any ideas whats up?
This just happened recently.
Also sometimes when I unlock the phone it randomly presses either the home key or back button. Any ideas on this as well?
the first is a software problem, a reflash should fix it.
the second is a hardware issue, could be caused by humidity inside the phone, remove everything from the phone (battery, cover, cards) drop it ina bag of rice for a few hours to soak up the moisture. if that doesnt work then if you're still under warranty you could get it replaced.

[Q] lock button starts camera after water damage

My baby boy decided to drop my motorola razr i into the toilet. After drying the phone with a cloth, initially the phone seemed fine. After about 20 mins the phone has a couple of problems.
The Lock button (and Volumn Up button) are starting the camera when pressed.
I tried rebooting (by pressing the Lock button + volume down together)....but the problem still exists.
I have tried the 'dry in a bowl of rice'....btw will that still work (its been a couple of days since the toilet incident)
Is it repairable?
thanks

Well, the usual rule of thumb for devices dropped in water is to remove the battery as soon as possible to avoid corrosion build up... the voltage present while the battery is still in place accelerates oxidation thanks to the electrolysis effect induced by the introduced water... since this is not possible in our beloved Razri, the least that we can do is to attempt force turn off by pressing Vol+, Vol-, and Pwr keys all at the same time until the phone shuts down...
I know this is coming after the damage, but is good to keep it in mind. this would not remove all voltages inside the phone, but would reduce the areas where oxidation might form... I do not think the 'rice bowl' trick will have any effect after two days, but there's no harm in trying... I would try to open up the device and try to clean as much as possible any trace of liquid intrusion... there might be some internal shortage creating this problem you're experiencing, and might be removable if you manage to open the device...
Good luck!

N7000 power button "fix"

Thought I'd share this with you guys.. it is already mentioned somewhere else in the forum but it's buried in a long thread somewhere, very hard to find.
Recently I started having a problem with my N7000. The power button was not working properly. Only the faintest of touches, would result in the phone turning off. Sometimes, the button didn't work at all. Also, the phone rebooted itself several times a day...
For me anyway, it was simply dust/dirt around the power button.
1) remove back cover, then use a jewelry screwdriver to take out 9 screws. Then unclip the phone from the frame. To unclip the frame, take a look at how it's done in this video: https://www.youtube.com/watch?v=N6CJy71_9Ok (1:52 mark)
2) wipe away the visible dirt/dust, and blow hard around the power button, volume button and usb port...
3) reassemble.
Hopefully, like mine, your N7000's power button is now functioning again. :fingers-crossed:

Endless safe-mode loop after water damage

Hi all!
My phone got water damaged (a little bit, the back cover wasn't properly put) and the phone now turns on only in safe-mode, even if I reboot, pull the battery or do a factory reset. My volume-down key doesn't work now, if that could be the problem.
Does anyone know what I could do?
Thank you
Mine was doing the exact same thing, except my volume-down key acted as if it was being pressed down constantly. I spilled water on it while on a cruise and it wasn't the same. My phone would constantly mute and the volume overlay was constantly visible on the screen. I had the safe-mode on reboot several times, I'm assuming holding the volume-down during boot is what activates it.
My fix was pretty brutal, I popped the volume button off with a thumb tack, then uses tweezers to rip the volume ribbon cable out of the phone. I now have to go into the settings menu to adjust volume, but at least the phone is usable. My hunch is that water damaged the ribbon cable via the volume button.
The actual fix would be to replace the frame/back housing bezel for the phone. It's only about $8 on Amazon (http://amzn.com/B00K458DUK), however it requires removing the screen. My phone has been dropped a few times so I'm worried the screen won't survive a transplant. A replacement screen is $150, so I've just been dealing with no volume control for now.
I see... thanks for your input! I'm guessing mine is having the same problem. I'm not comfortable doing the brutal fix myself, but I don't know where I could take it around here to get it fixed.
