ThinkPad Edge E525 NZ632GE - WINDOWS XP - very low brightness in battery mode

The pm-driver seems not to work (-> WINDWOS XP). CPU frequency is always at 1,9GHz (2,5 GHz) and energie profiles which are set in (lenovo) energie manager have no effect. In power-on-mode display is ok, but in battery mode its very dark (no effect with f6/f7 without fn). How can i increase display brightness in battery mode? Is there a registration key i could change? Or tool? Or newer drivers? (I have solved the CPU frequency problem with the tool k10stat.)

Hi all

@ Moderator or Staff
I guess this two thread can be merged to one

@ e525
I have replied your PM. I don't think manufacturers would release beta BIOS or drivers for business machines, it could be risky / unstable. I am not sure if other people with Edge E525 are having the same issue, you could probably run System Update and try to update all the drivers, etc. If not, you could try to uninstall and reinstall Power Manager, Power Management driver, On-screen display and GPU driver. http://support.lenovo.com/en_US/downloads/default.page? 

 

The better option would be contacting Lenovo Staff or Support through phone and they will be able to resolve your issues.

Happy New Year! :smileyvery-happy:
