Is there anyone who have a solution ?
When power up, screen will show welcompage for a few second and then go to "black".
Normally you can startup screen by point at the screen or clicking mouse but not now.
Video timeout/sleepmode/standby, does this exit ?
When external monitor connected , this montior show screen as it should be.
When changing for instans, screen orientation, the tablett screen lightsup with right information and then goes "black" again..
