On windows vista and seven my dell never reach over p12 state 135-135-270mhz and p8 state 405-324-810mhz
On windows xp it working well and no problem with p0 state 550-790-1210
I have try various driver (official) and fresh not official but only way that I have to work on p0 state is:
Reinstall driver without restart the system, in this case it is working, but if restart the system it reach only maximum performance to p8 state 405-324-810mhz.
At the moment I have the A15 bios, but I have test also on A10-A12-A14 bios version.
what's wrong ?
