Display changes to very low contrast and high brightness while in dockingstation

Hallo everyone,


the display of my T510 (typ 4337) chnages the brightness and contrast itself while in dockingstation. The contrast gets very low so that neither backround nor icons are clearly visible.The only thing that helps in this situation is a reboot of the system.

Sometimes it happens twice a day in other times only once a week. Since I have to work with my T510 its annoying to shot down the system in the middle of day.


I updated the video driver as in other post recommended:


I also updated with the lenovo updater and search the web for the newest video driver.

Has anyone the same problem and found a solution?

System is (from Intel Info Center):
OS: Win7 (64bit) Service Pack 1
Model; T510
Driver version
Processor Intel Family 6 Model 37 Stepping 5

Accelerator Information:
Intel HD Graphics
Video BIOS: 2117.1
Graphics mode 1920 by 1080

Any help would be appreciatediciated Thanks in advance.
