I guess i've never really had problems with my Powerbook.

But hey, last week my iPod died, and then my car broke down...so I guess it's only appropriate.

Anyway, I have a 1.67 G4 PB, supposedly 1.5gb RAM. Well, I know it had 1.5gb RAM, I installed it myself. I have the 512mb that came standard, and a 1gb I got from Newegg. I noticed today while I was cleaning up files that "About This Mac" only showed 1gb of RAM!!

So I went and found this:

Power On Self-Test:

Last Run: 11/11/06 12:22 AM
Result: Failed
Failure type: Memory
Memory slot: SODIMM0/J25LOWER

Now what? I have Applecare, just don't know what to do. Will they just send me new RAM? Ughhh I'd hate to go without my PB for days for something so trivial.

Since you posted twice (http://forums.macnn.com/90/mac-os-x/.../#post3201342), I will too.

PowerBook + missing memory sounds like the infamous lower memory slot failure.

Hmmm..thanks I checked that out. However, my serial # isn't within that range, I didn't get this laptop until June 2005.

Is it safe to turn the computer off and switch the RAM chips around to see what happens?


Hahah and I guess I didn't mean to post twice, the first post had slipped my mind when I saw that power-on self test.

Argh, no! You were right. It IS lower slot failure.

It's okay though, I just got my laptop set up for an all-expenses paid vacation to sunny sunny Cupertino.

Exact same problem. Mine was recently purchased duff 1 gig stick of Ultra RAM. I've also heard that 512 and a gig sometimes don't play well together. Going for a Crucial 1 gig stick tomorrow...
