Nexus 7 2012 power button triggering itself
I am having 2012 wifi 8GB N7 for more than yr now and have recently started getting irritating problem making it unusable.
Its behaving as if its power button is continuously pressed even when i am not touching the tablet or sound / power buttons. Its operating on its own to restart, bring power menu in every situation i put it in, like in system standby condition, powered down condition or in bootloader or even in CWM recovery. Its operating function corresponding to power button.
Tablet is out of warranty so i am trying to troubleshoot and fix it myself (as far as i can) and but getting any clues from online available material too. Also out of warranty repairs are costly / worthless if service guy decide to change its PCB.
If anyone has faced similar issue/ got solution/ got it fixed from service guys, please suggest me what can be done. Is it a software issue or hardware issue like.
So far I have tried factory roms of 4.2.2, 4.3, CM versions and AOKP versions in rooted, non rooted, bootloader locked unlocked conditions. And from my understanding its not related to any roms. Heck it shows this erratic behavior even in bootloader mode or in CWM recovery.
Can there be anything which service guys do as far as software is concerned which we cant do, so that i can give them to fix it?
