PowerBook Pismo with a Wegener Media 550 MHz G4 upgrade In the last couple of weeks, my Mac started just shutting-down all of a sudden. (Not a proper Shut-Down; like pulling the plug.) The Mac runs for between one & three hours, then spontaneous power-down.
First thing that came to mind was: Power Manager. So I did the drill: PowerBook (FireWire) 1. If the computer is on, turn it off. 2. Press and release the reset button located on the rear panel of the computer between the external video and modem ports. 3. Wait 5 seconds 4. Press the power button to restart the computer. Note: Resetting the power manager also resets the Date and Time. After the reset, the system clock will be set to 12:00 A.M., 01/01/1904. (Removed expansion bay battery, ac adapter, all cables, expansion bay devices, pc card — everything — for a "deeper" reset.) Then I reset the PRAM (reboot, Command-Option-P-R, five times in a row.) Then I did the Open Firmware resets: reset-nvram set-defaults reset-all Didn't make a difference. I run Temperature Monitor all the time, and the Mac isn't overheated when the power-downs occur. (109 F or thereabouts; it takes 116-120 F to make the fan come on.) Any ideas?
