Hi there, I've a Compaq PP2140 to which I plugged in a laptop universal adaptor since its original got lost; now it just won't boot up or do anything else but a short less-than-a-second screen blink when turned on; then hdd light turns off, and the only lights that remain on are power-on, AC-IN and batt charge, this last one blinking all the time (1,5 blinks per second). I must say that this computer has been off for over 3 months, stored at a shelf in a bedroom.
What I've tried so far: remove batt, clean-up RAM slots with isoprophyl alcohol and replace RAM modules, remove HDD and re-insert it.
Any help will be appreciated.
Thanks a lot.
