I'm currently struggling with the same issue. I figured out that the additional processor power options become available after installing Lenovo Power Management Driver . However it didn't help me much. Both cable and battery setting is set to 5% by default. This issue is driving me nuts.

I called Lenovo, and they updated the computers BIOS.

 

If that didn't work, they are going to send in for repair.

 

I'll keep you updated, but you can try updating your bios to 2.33

I've found temporary solution for my problem. Right after installing AMD drivers using auto-detect tool I changed: power management -> (balanced) -> advanced settings -> ATI power settings -> set "Maximum battery life" for both, connected and battery. After that no freeze happens when power cord is being connected and no black screen when windows is starting.

Hello everyone

 

Unfortunately, I also have this problem. Laptop works only at Maximum battery life in ATI Powerplay settings. Also its can freeze during watching  online videos like Youtube or Facebook.

 

I installed the latest drivers after cleaning the system from the previous in safe mode. Back to previous drivers also did nothing. Even if these versions where you can turn off ATI Powerplay its still freezes when u try to put on maximum perfomance mode. I installed the drivers in safe mode. I updated the BIOS.

I repleaced thermalpaste on CPU and GPU and nothing. I put on GPU a copper plaque instead copper coin and still nothing.  I removed the memory modules to see if any of them does not cause a problem. Overclocking card is also unavailable due to the ATI Powerplay takes only 300 mhz.

 

After a few weeks of digging I am really tired of this issue. I never thought that after such a long time use and care of the hardware this happens..
