Greatings!

I'm now in the community, so apologies if i skip procedures, if there is any.

I did a silly thing on my powerbook G4, i change the hinge of the screen following the instruction from ifixit.com, so i remove hard drive, motherboard and almost everything.
When i put all the pieces back together and i tried to get it working, there was the problem:

The computer switched on but there was nothing in the screen, just the sleeping light on and blinking twice every 10 seconds.

Does anyone have any idea what that means?

Woulb very helpful, if is something easy to fix, before taking it to the doctor.

Thanks a lot.

First check and make sure you din't leave anything un hooked and have everything plugged in securely.

You were right!!

I knew it had to be something like that but i didnt want to take the whole thing apart agian, but it was the RAM memory.
well now i know for next time what that light blinking means.

thanks a lot for your help
