So yesterday i was just doing some general browsing on my tablet. I received a warning that my battery was low at 11%. A minute or two later it died so I figured the battery percentage was just in accurate. After I plugged it in and let it charge I tried to turn it on and the tablet boots up just fine, but the screen doesnt turn on at all. No backlight, no anything. It boots up ok since i can feel it vibrate, adb works, and i can hear the chimes for new emails and notifications. I pulled a logcat from the boot up process to see if it tells me anything. In the logcat i keep seeing this line of data show up:
E/hwcomposer( 155): /sys/class/graphics/fb0/device/smartdimmer/enable: open failed: Permission denied
E/hwcomposer( 155): Failed to set initial DIDIM status to enable
D/hwcomposer( 155): Display 0: found 2 modes
W/hwcomposer( 155): Skipping mode with invalid timing (1920 x 1200)
D/hwcomposer( 155): unmatched: 1920 x 1200 @ 59.95 Hz
D/hwcomposer( 155): display type 0: vblank period = 16679218 ns
D/hwcomposer( 155): dc_blank: display 0, [-1 -> 0]
So my question is, is there any chance that it is some sort of software issue not allowing the screen to turn on or I just get the errors due to the screen not working?
