Chromebook not opening after being left overnight
Tldr: Caffeine run out, fell asleep without unplugging the chromebook (no battery) and the next morning it won't turn on now.
The only noticeable thing i got is this part buzzing when connected to power:
feel free to ask whatever question needed for this fix

@johnrey24668 Try this first. Disconnect the power from the computer by unplugging the power cord from your computer. Disconnect all external devices from the computer. Now hold the power button depressed for about 30sec-1min. Reapply the AC power adapter and see if your computer does show any sign of life.

the thing is, i've done this power drain before, not even once or twice, but more than thrice. even the battery was out since it is already dead to begin with (already removed even before)
