I bought my 1.25Mhz 15" PowerBook about a year ago. For the first few months, I had virtually no problems with it, but at some point, with one Apple's 10.3 updates, I believe they introduced a problem that either causes or exacerbates the infamous "sleep of death" problem where the system will not wake up when you open it.
I don't know if this is the same "sleep of death" that was originally seen on older Mac laptops, but the symptoms are basically the same. You flip open the screen, hear a small amount of disc activity, but the screen remains black and the system is hung. You have to do a hard reset to recover.
I saw this problem every now and then with 10.3, but now that I have upgraded to Tiger, it is much worse. Along with the inexcusable breakage of SMB, I'm starting to regret having upgraded.
Has anyone managed to come up with any further insight on this problem? I've seen a lot of discussion about Bluetooth & USB mice and keyboards, but I'm not using any of that.
