I don't know what's going on!?! I installed Opie 1.2.0 on my SL-5500 after using GPE for a couple of weeks, an I found a major problem! When I shut off my Z using the On/Off button on battery power(fully charged or otherwise) I can't turn it back on! Battery status prior was fine. Not running any apps at the time either. Also, while on AC power, it's fine.

I can shut down and power right back up without a prob. While on battery power, if it auto shuts off from the sleep mode timer, I can start it back up as well. After reboot, it's fine, until I plug in external power...then the problem stats again, but in reverse. Once off an AC power, I can't turn it back on until I reboot. Is there a know app or other such issue that would cause this?

update kernel - howto is on openzaurus website

Thanks alot! That did the trick. I have to say, these forums are a great place to find the answers you need.
