I'm experiencing an issue with screen brightness control on my E520. Whenever I reboot the system, the brightness turns to maximum, then when I relogin into windows the Power Manager automatically starts up and sets the brightness according to its settings. This works only if the Power Manager's option "Show Power Manager Gauge in task bar" is left ticked, because with that option disabled the Power Manager doesn't automatically adjust the brightness on startup.
There are 2 problems:
1) on every reboot the brightness is turned to maximum (on every other notebook I've seen the brightness level is kept).
2) the Power Manager doesn't work without the green battery meter on taskbar. I want it to automatically adjust the brightness on startup but I don't want the battery meter on the taskbar.
I'm on a fresh windows xp installation and I have all the updated drivers (including intel chipset, intel management engine interface, lenovo power management) installed.
Has anyone a fix for this?
