I have seen a few other bug reports for other laptop manufacturer and come to the conclusion that this isn't limited to my brand, but instead of filling up other bug reports i choose to add my own to get a clean approach to this issue on VPCCW1S1E laptops. If this isn't a correct way please specify which bug i should attach my information to before making this one invalid/duplicate. I have gathered the following information from my system and hope that it is at least a start in finding a possible solution for this problem. Note: There is no difference when switching to or from battery power.

One other thing with this laptop is that sax2 cannot properly detect the internal display, which results in black screen, i have manually overcome this issue but don't know if it is somehow related to this issue, but should it be so i can provide information regarding that to. Is there anything else i can check/provide to narrow down this issue. /Marcus Reproducible: Always Steps to Reproduce: Happens directly on fresh install of 11.2, no changes with applied updates. Actual Results: Display doesn't change brightness on button press or when switched to or from battery power. Expected Results: Brightness changing. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
