T400 swichable gfx in windows 7, where?

[MiRacL]

Hello

I just bought an T400 with the switchable gfx. I've just installed win 7 on a SSD. I've installed all the drivers from Lenovo, but the one thing i cant change is the switchable gfx. Both cards are installed and working, but i cant find the switchable gfx options as stated in the install instructions for the driver from Lenovo. When i left click or rightclick on the battery icon, the "switchable gfx" option isn't there.

Anyone have any ideas?

Confirm the BIOS setting is set for switchable.

T400 specs:

T8600
SSD
8gb ram
1440x900
Intel + ati 3470 gfx.

I'm typing this on a T400 running Win 7 Ultimate x64, and the switchable graphics option is definitely there when I right-click on the tool bar PM icon. I'm running PM 3.64

ATI Mobility Radeon HD 3400 Series
Mobile Intel 4 Series Express chipset Familiy.

The driver for the "mobile intel gfx" are from AMD, this can't be right? I have just installed the "Switchable gfx" driver package from the lenovo site.
Haven' installed any windows updates yes, like SP1.
If i right click on the pm icon the options i get are:

Adjust screen brightness
Power options
Windows mobility center

I presume you meant ATI, and yes, it is an ATI supplied driver.

On my T400 the Intel driver is version 8.792.5.0, while the Radeon driver ihas the same version number. This is the current switchable graphics driver version on the Lenovo support site.

Yea. It's the same driver i have. Still missing the option in the power manager. Weird.
