I am currently really happy with my T60p running 10.6.8. Everything works including sleep thanks to this forum. There is one issue I cannot seem to fix though: Sometimes when I do things that demand a lot of what CPU and GPU have to offer and the laptop is on battery power, the screen turns blue for a few seconds. It doesn't switch instantly, instead the screen fades to blue (it is the same effect that you get if you change the screen resolution). In IORegistryExplorer, I noticed that this happens: https://skitch.com/unbehagen/8288q/applebacklightdisplay
- OS X seems to remove and re-add the display device for Wormy. This only happens when it is on battery. Does anyone else have this issue with the ATI v5250 or an idea what might be causing this?
