HI! early 2008 MBP 4,1 startup or power up Failure! HELP! thks!
I have an early 2008 Macbook pro 4,1. The computer was sleeping all night, and when I pull up the screen to use it, the Mac apparently was running but no screen on it, so I try to increase or decrease de light on the screen but nothing happened, so I force it to shut down with the power bottom, then I tried to power it up, and it really does for 2 to 3 seconds, and it shut down... there is nothing at screen. What i did to troubleshoot with no results: press de power bottom for 5 seconds with no mega safe adapter and battery - press de left shift + option + command + power bottom with the megasafe adapter - I did take the HDD - took de RAM memory.
Another thing: When I took the Ram memory the MB stayed beeping like telling me that there was no memory, but it didn’t shut down. I had to shut it down myself...
Any suggestion please!? Thanks a lot!
MacBook Pro, Mac OS X (10.6.8)
