Hi there! I have a couple of questions. 1. On the very newest Aluminum Powerbooks (15" and 17" 1.5Ghz models), is the video RAM expandable from 64MB to 128MB by adding the proper memory chip or card to the motherboard, or is this RAM physically soldered onto them? I'm wondering if it's possible to upgrade to 128MB from a stock 64MB configuration, after the initial purchase? 2. I have a beige G3 "all in one" Mac over here (donated by a lady who was having problems with it), and I can't seem to make it work right either (despite being a computer tech with 14 years of experience!). The problem is, the system will appear to be running just fine and then it suddenly freezes up. I assumed it was bad RAM, but I've swapped out memory with at least 6 or 7 different modules (64MB, 128MB and even 256MB, some PC100 and some PC133). Some of the RAM, it doesn't seem to like at all (just gives a black screen and won't boot). Other RAM, it seems to be fine with but eventually freezes up again while using it long enough. Does this sound like it's just a bad motherboard? (Wondering if anyone out there might have supported/administered these all-in-one G3's in any decent number, so they'd have extra insight as to what tends to fail on them??) Thanks!
