Toshiba L750 Laptop won't power back on after shutting down
I'm hoping someone out there might have a solution to strange issue I am having with a Toshiba L750 laptop running Lion.
I've managed to get the OS installed and the hardware working but have an issue when shutting down the machine; It will actually turn off the machine but when I try to power back on, nothing happens (the power button simply does nothing) I am forced to physically remove the battery and unplug the a/c, then replug it in order for it to actually power back on.
I've tried using OSXRestart.kext, ev0reboot.kext, and OpenHaltRestart.kext with no effect, tried removing my DSDT alltogether with no effect, tried safe mode, 32-bit mode, all with no effect. Updated BIOS with no effect.
I'm running out of ideas as to why this is happening. I'm hoping that someone out there has experience a similar issue and might know of a possible fix or work around to this problem.
I've done a number of hackintosh systems before and never ran into this type of issue. The laptop itself otherwise is running Lion quite flawlessly, so this is something I would really like to resolve. Please let me know of anything you think might fix the problem I've described.
