Powerbook Memory Problem

[micart671]

Hello,

I've discovered that my powerbook with 2x 512mb memory boards installed is only recognising the upper memory board.
In system profiler it states that the lower slot is empty.
No matter what combination of install i do, the lower slot will not recognise the boards.
Both boards are ok as i have installed each individually in the top slot.

Any info will be greatly appreciated.
Thanks
Mic

Hello -

Someone in my family has a PowerBook with the exact same problem! There are three reasonable solutions:

1. Don't use the broken memory slot
2. Get your PowerBook's logic board replaced
3. Get a new computer

I wish replacing the logic board on a PowerBook wasn't so darn expensive AND required being without it for 5-7 days.

You will have to replace the logic board to get use of that slot again.

You can try finding one on ebay. I really wish apple would drop the prices on replacement parts for their older machines. It's really really absurd that they still want to charge you like 700 bucks to replace a logic board in a 3-5 year old machine.

Replacing logic board

Tell me, why can't someone clever enough repair these boards? I've heard they can't be soldered?? Why oh why?

Check with Apple Service, there was an extended warranty program for this at one time, but only for a restricted range of serials. It is a well known problem that affected a wide range of 15" and 17" AlBooks.
