Daca ai placa de la amd incearca acest fix
Right click on [charge icon] in taskbar and select "power options"
to the right of the currently selected power plan click on "change plan settings"
Then click "change advanced power settings"
in drop down list select which ever selection has "[Active]" attached to it.
Then scroll to bottom of list where you should find a listing "ATI Graphics Power Settings"
Expand this listing and its inner "ATI PowerPlay Settings" until you see the "On Battery: and Plugged in:" options are shown.
change the "On battery:" option to "Maximum Performance" and click "OK"
This may reset your default screen brightness to %100 on battery but you can manual set to anything lower in the "change plan settings" area and the screen with dim to entered value as it should and without atibtmon.exe error and no more error upon waking from sleep mode, which apparently didn't actually work at all with out this fix.
again this worked on a Compaq cq62 and seems it should work on any other with ATI mobility radeon chipsets
