I don't know what that bumping sound is. Are you continuously hitting the power on button?

First thing to do is to replace the PRAM battery. It is a 3.6 holy 1/2 AA battery on the logic board.

Does it have a hard drive in it? Do you have any history on the machine?

yes i was hitting the button.

i take out the battery because it was leaking acid, and it makes a mess with the ram, only two survived.

yes it have the hard drive, but i don't know much of the machine, i only know it was not turned on for ages.


Just hit the button once. It gets the message. Replace the battery. See if you can get a history. Use some canned air and blow it out.


at the start the video i hit the button once, the only thing i know is that it has been staying for almost 6 years turned off in a humid place.
