My lil sis accidentally knocked an empty glass over. Except it wasn't empty. A few drops, which entered the laptop. Didn't notice initially. Had used laptop in the morning without any problems. Then tried to use it later.
Initially it wouldn't switch on - there were no lights for power/battery/Ac power. Left it a lone and tried again. Powered up but froze at post. Then tried again and it froze but the screen wasn't working. Examined it over and noticed drops of water.
Cracked it open, took it apart, tried everything out, cleaned it all up with IPA. Checked the connections. Still won't pass POST, and nil on screen.
