Anyone else had this?
My 5-week old (shiny) 512meg Powerbook now only shows 256megs of ram, the lower slot is flagged as not there. Noticed this for the first time today running FCE which used to work fine, which now says "I need at least 392megs of memory".
Switching ram chips around doesn't change the issue, so both ram chips are ok. It seems the lower slot has just stopped working... If I just boot up with one ram chip in lower slot, pbook beeps three times and refuses to boot. Using either chip in the other slot it boots fine.
I have tried reinstalling ram and trying to put the lower dimm in with some force - it seems to be in fine, the same as the slow above it, but no dice.
Resetted the PRAM, done the full reset from Apple's procedure and run the hardware test. All say lower slot buggered
Apple say I should send it back to them, but that's two weeks of downtime.
Any suggestions?
