T500 - Switchable graphics: Integrated + sleep = Integrated + Dedicated on wakeup

Hi

 

When I put my T500 to sleep in integrated graphics mode and wake it up, it seems like the dedicated Radeon starts using up power as well as the integrated intel GPU.- The battery is predicted to last about the same amount of time as when I use dedicated graphics. When I switch it to high performance and back to energy saving again, the power consumption goes back to normal

 

Any ideas?

 

Windows 7 x64

Power manager 3.05

 

ATI:

Driver Packaging Version    8.641.1.1-090824a-089811C-Lenovo

Any updates? When is lenovo planning on fixing this? This is clearly not a Lenovo "Enhanced" Windows 7 laptop if a problem exists such as this.

It seems that Lenovo needs at least 6 months to update the switchable graphics drivers. If this estimate is correct, then we can expect a driver update in April.

I found a tool that will switch to discrete, then back to integrated.

extract the folder somewhere on your machine, then make a desktop shortcut to the .exe with the switch /resumefix

 

Not ideal but it is a one click solution to lower consumption after coming out of sleep.
