I have a very similar configuration, ATI mobility Radeon HD 3670 on Dell XPS Studio 16 using Windows 7 64-bit, and have the same problem of
atibtmon.exe throwing an error every time power is removed. The difference is, I do not have Catalyst Control Center installed and wish to avoid it as much as possible. It's a memory and CPU hog, and tends to leave corrupt installations which make deinstallation or upgrading a pain. So, I'm trying to find a way to do this directly, by whatever means CCC internally does it.
After some ack-ing and some googling, it looked like all I needed was to set a registry key
PP_VariBrightFeatureEnable to 0. However, I've searched the registry all over (even with some regex-fu on Regalyzer ), but haven't been able to find such a key. I don't know where it's supposed to be so I'm unable to add it manually either.
Does anyone know the correct way to do this? The setup's .inf files have the string
:HKR,, PP_VariBrightFeatureEnable which looks like the key goes somewhere under
HKEY_CLASSES_ROOT (I'm assuming they're using an unconventional abbreviation of this one), but I'm not sure where exactly or even whether this interpretation is correct.
