Hi,

first check BIOS settings. My thinkpads provides in BIOS settings for brightness in case of with or without AC power. Otherwise this is an ACPI case. There are a lot of notebooks having non ACPI compliant DSTN table, which means Linux kernel won't be able to provide all ACPI functions available.

Did you take a look at Linuxlaptop or Tuxmobile? There you can find additional information for various types of notebooks on Linux.

I think its not the BIOS cuz am having two operating systems on the laptop & the other 1 is working gr8 wz the brightness .. so its with linux .. so it means that the Ubuntu wont support this option on the laptop or what?
