8.10: resume from hibernate xserver does not start with batterie

[Uwe Brauer]

Hello

I have a Thinkpad X60s Laptop with 8.10 installed.

The xorg.conf files tells me that the graphic card is 


Section "Device"
	Identifier	"Configured Video Device"
EndSection

Anyway: 

    - when  I have the cable   plugged  in hibernate and   resume
      everything is fine.

    - when  I have the batterie    plugged  in hibernate and   resume
      everything is fine.

    -  when  I have the cable   plugged  in hibernate and
       resume with the batterie, the xserver does not start up!!!


I don't understand that

Can somebody help me?
