I know this is not the best place to ask for help with Macs, but this group is the most helpful and responsive that I have ever had the privilege of belonging to, so ....
My Powerbook started acting up this morning, I browsed my usual sites, A.org, Amiga on Ebay, Lemon Amiga. I then had to go out for a few minutes, put the Mac to sleep, and when I got back and opened the Powerbook, it only showed the screen for a few seconds before going black. I hit some keys to wake it up again and only heard the keyboard sound when you click on an option that is not available. I closed and reopened the Mac several times, and each time the screen would display for even less time before going black again. I shut down completely and cold started. The screen displayed almost long enough to log-in the first cold start, but then went black again. Each cold start shows less display time. I am off now to check some Mac sites for help, but will be right back.
Any ideas? :-?
