12" PowerBook does not wake from sleep
my A1104 doesn't wake from sleep any more. When it goes to sleep, the sleep light begins to flash for a fraction of a second and then goes off. At that point I have to reset the PMU (ctrl-shift-opt-power) in most cases to power on again.
Initially, this happened only with the (almost dead, just enough capacity to boot) original battery place, even when running on mains. After a few days it also happened with a aftermarket battery with ~40 cycles and also with no battery installed.
Things I tried:
- two different batteries, but also mains only
- bring to sleep via lid close/menu/command line
- removed every unneeded peripheral, including AirPort card and RAM extension
- boot with a fresh OS X 10.5 installation from external Firewire disk
- boot with Gentoo Live CD
- zapped PRAM
Should I try to get another DC-to-DC-board?
Anything else to try?
