Adding Memory to Powerbook G4

    I have a Powerbook G4 that I wanted to upgrade to 1.5G from 512MB. So I added Corsair 1GB DDR RAM to the notebook and it seems to have issues recognizing both at the the same time. When I put both of them in together, it never seems to recognize the bottom slot. Putting in the 512MB in the bottom w/o the 1GB the Powerbook boots up fine. Putting in the 1GB by itself and it gives beeping noises on bootup, but it'll boot up if I put it on the top slot.

    Any ideas what the problem is?

    Do you have a 15" Powerbook with 1.5 or 1.67 ghz G4? If so, read this thoroughly. The bottom memory slot failure is a known issue with these models.

    Yeah, I have the Powerbook 15'' with 1.5Ghz.

    Though my Powerbook's serial number is W85361XXXXXX :(; making it ineligible for this program.

    I would still contact Apple and ask if they will repair it.

    It's not under warranty anymore though, so will Apple still look at it?
