Computer works, just minus the lower memory slot. (although I do experience the screen flashing with strong vibration applied to the casing) I have noticed it happened a couple of days after I made an update, but am unsure if this really is the problem. There is an alternitive theory, that the lower memory slot can malfunction due to prolonged Powerbook "carrying"... holding the computer with one hand / in the corners, can "flex" the structure and in turn afect the logic board inside. My PB is well outside of warranty now, which is a real pain. Will there be a problem with not addressing this issue? Could I get by using a 1gb stick in the remaining slot? Anyone had experience with that? I have an Aluminium 1.33 G4 Powerbook, and had this happen to me this week.

My beloved 15" Powerbook locked up hard back in March 2005, almost 14 months old then. I subsequently rebooted it and it started up without it's normal chime. Then I noticed that I did not have access to quite as much RAM as I had a few days ago, and System Profiler claims that my botton RAM slot is empty. The screen flickers when typing on the keyboard and the system boots up very slow (this was even recognized by the Apple Genius when taking the Powerbook to the Apple Store in New York). My lower slot is apparently not broken as the Apple Genius tested both chips and confirmed a problem with the logic board. I was told that this is a known issue and have found numerous threads on Apple’s discussion forums. A few case numbers with similar issues are: R3350484, R3312665, D3875055, 46975803, 47015502, 43237673. In some instances the lower slot failed a second time and it sounds to me as if Apple does not have a fix for this issue, but simply puts in a new logic board that has the same potential issue. I would truly appreciate if Apple could look into this issue and acknowledge it as a manufacturing problem. Though I have Apple Care until end of 2006 I don’t want to experience the same problem after a couple of months. MacFixIt.com also covered the issue in length for a while. I still haven’t got it fixed though: because I won’t get a replacement, and Apple Europe states that I could have to wait for SIX WEEKS to get my Powerbook back. By the wayt, the RAM was purchased from Tekserve in New York, an authorized Apple reseller for more than twenty years, and installed by their experienced staff. The chip is listed as compatible with the Powerbook G4 15’’ on Apple’s website and meets Apple’s specifications. Best, Jurgen Proschinger - Gryphon Entertainment - That sounds familiar!

I have a 12" Powerbook that I purchased in June of 2005. A month ago, it began freezing constantly. I sent it in to Apple Care to be fixed. Ten days later, I got my computer back, turned it on, and nothing happened. It froze the first time I turned it on after getting it back from being fixed! So, I sent it back. Now, almost everything has been replaced inside, and it works. Or so I thought. Now, I only have 384 MB of memory when you look at 'About this Mac'. Every restart confirms a failure of the memory. I should have 256 MB in the 2nd memory slot, so I'm assuming it only thinks that half of it is actually there. Furthermore, the fan runs constantly now as a result, and, of course, it is running much slower. I'm pretty pissed. I hate my computer. I have been without a computer now for almost a month, and I am a student. This is not acceptable. You are not alone. I have a 12″ Powerbook that I purchased in June of 2005.
