Hi all. I have some strange problem, i'll try to describe it.

There is HP notebook with obsd and Linux inside.

When i work in obsd screen goes to black, but notebook still work and i can
type "^C reboot" if i was in terminal. One time i work two hours, another -
just 15 minutes before this occassion, so it's not a time function imo.
Next. When i reboot i got standart HP logo on start up, but turned pale. And
after then - where must be grub and so on - is nothing. (I think there IS
grub but i can see it).

This can be fixed by following next steps:

1. got black screen.

2. turn off notebook by any way.

3. pull-out adapter from notebook (!)

4. turn on and enjoy white HP logo

5. return adapter cable to the jack

And. On Linux there is nothing. All work fine, with screen-sleep-state.

Any ideas what is it and how to fix?

If need any output, just say.
