I kept the Lenovo driver and just installed the one from ATI "over" it. Don't know if it works, when you uninstall first - however, this would be interesting.

 

Greetz!

Under Vista this approach didn't work. Can you also provide a screenshot of the "Details" to see which driver files you're using?

I only tested Win7 x64. My details look like this (after standy, thus two adapters):

Dear Lenovo-Support-Team,

I have seemingly the same problem. When I wake up the W500 with integraded graphics, it draws much more power! When do you plan to fix this?

 

Thanks!

Welcome to the forum!

While there are a few Lenovo employees in here helping out on a volunteer basis, this is not an official support channel with dedicated Lenovo support personnel assigned to it. Instead, this is designed to be a user-to-user support and discussion forum. You may or may not get an answer directly from one of the Lenovo employees as there are way more of us than them and all of them, even Mark and Cleo, have full-time jobs doing other things.

JaneL: thank you for your post. You seem to suggest that the silence of Lenovo employees on this topic has to do with workload. What makes you think that this is true? - I have good reasons to believe that it's rather corporate politics not to acknowledge this problem.

RealStranger: When you look at the driver version for the Intel card, it is the same version as what I have currently installed (with the official Lenovo drivers). The driver version for the ATI card is the new version from the Mobility Radeon package. 

 

So I would say the notice with the new ATI driver package - that it does not support Intel based switchable graphics - is probably true and you need the Lenovo package installed first for this to work.

 

But it still is good news that you can at least update the ATI driver version and still retain the switchable graphics functionality. It has been quite a while since Lenovo released a driver themselves :-(

Hi,

 

the Intel driver version is 8.641.1.1000, date 8/24/2009, so it is the version, released by Lenovo.

Another two weeks passed. Is there an update on the driver situation?
