Ok, so I have an Acer 5742Z-4685 laptop that won't turn on or charge. The external power supply is working and receiving power from, and the motherboard is getting power from it (measured both with multimeter). I also tried a kind of reset, took out battery, held power for about 35 seconds, and tried to power the laptop without battery. Nothing. There was a recent incident, though. Someone tried to clean the computer with water and it wouldn't turn on, but we had dried it and it was working fine for a bout a week. The only trying that was affected was the keyboard, which we ordered a replacement for (it should be coming today). If anyone has any idea about whats going on, I would really appreciate it, because I might have to return the keyboard if it is not going to work again. Thanks in advance!
