Thinkpad T400/R400 latest BIOS (3.19/3.17) has a BUG! As a result, the performance of ATI is reduced by 3470!

My situation is the same as described in the first post.

 

My notebook is r400. After the BIOS version 3.17 is switched to Ati's unique display, it will lead to gray or other light colors, and it will show spots similar to marble textures or cement walls! Performance is also said to have declined!

 

The atigraphics card driver was reinstalled n times... Finally, we found the BIOS head... Call...

 

Click Back to version 3.18/3.16. The problem disappears.

 

It is said that the new version of BIOS is designed to solve the problem that the screen has water prints... I did not expect such a big bug...

 

I hope you should pay attention to this when refreshing the BIOS. If there is no problem, do not brush the BIOS blindly. At least skip this version...

 

 

Note: The Historical BIOS version is at the bottom of the BIOS download page on the Lenovo official website.
