My device was working properly but its temperature was high, so I opened it to clean.
I have experience in cleaning laptop, so I think i did everything right, except for not disconnecting battery while cleaning. But I think it was ok because all I did is do a little bit of vacuuming the fans. I didn't touch other components.
Unfortunately, after I plugged 2 cables for the monitor, I tried to hit power button, it didn't turn on. I tried to hold the power button, but it didn't work.
I notice that the cpu was warm and there's coil whine noise (little buzzing noise on the back, at the position of the cpu). But the lights are off and there's not boot sound.
I didn't try to plug in the power cord.
Does anyone have any idea what's going on and what should I do?
