 Post subject: macbook pro 17" no power at all
PostPosted: Fri Jul 11, 2008 11:17 pm 
Hi - My macbook pro had a bad magsafe cable and fried my left i/o board.
I bought a new magsafe connector.

I saw on the logic board where the part was burnt. It is right by the magsafe connector.

I bought a new left i/o board and replaced it..

The computer still will not startup.
I dont have the hard drive in, will this cause the computer not to have power?
Is there a cable between the left i/o board and the logic board that could be fried as well?
I took out the logic board to see if there were any burn marks and found nothing.
I have made sure that the ram was seated properly.
I tried to reset apples (PSM) -Portable System Management Controller buy removing battery and magsafe and holding down the power button.
There is no orange charge light on the magsafe power supply.

Is there a way to test individual boards?
maybe the left i/o board I bought is defective?

any help is welcomed!

thx
Paina
