MacBook won't stay on unless a key is held down
Just bought a used MacBook late 2008 model (first Mac computer) now the problem I'm having is it won't stay on unless a key (any key) is held down the entire time from the moment it gets powered on, as soon as you let the key go 2-3 secs later it'll power off, seconds later it'll try to boot up on its own once it gets to the loading grey screen if I'm not holding a key down it'll reboot and do it over and over until batt dies, previous owner said he did spill some liquid on the keyboard, all keys and trackpad work, took it apart earlier and cleaned the logic board with alcohol, let it dry and re assembled same problem, anyone have any ideas as to things I can try to narrow down the problem or know what I need to replace?
Serial # W8*******1AQ
Any advice is greatly appreciated.
