Thanks for posting this note. I found the flutter problem as you described. When I complained to Lenovo, they asked me to send the laptop to their repair depot. They paid the postage, etc. The experience with the depot was really not very good.
The depot tech did not have the letter and photographs that I sent in the box and had to go find them. She asked where the battery and AC adapter where. I told them they were shipped with the unit.
The depot reported that they could detect no errors but set bios to the high performance mode on battery. The machine was returned to me without the battery I had sent to them. It was also dead on arrival. It would not boot.
After working with the techs via the phone, the problem was escalated to a very helpful lead tech. He got onsite service for me and ordered a new motherboard. The motherboard shipment was delayed and I had a dead machine for several days. The onsite tech replaced the motherboard today. The machine boots but still has the graphics problem.
By the way, setting the system to maximum performance on battery does not cure the problem on this machine.
Lenovo has ordered a third motherboard and intends to do another replacements.
It appears taht this is a generic problem. I'm disappointed that Lenovo doesn't recognize this. I also know that I will never again send a computer to their repair depot.
One thing I found was that the problem can be seen by running the Tool Box graphics stress test. With the AC atadapter connected, the graphics are great. Disconnecting the AC adapter results in the graphics "flutter." This can be repeated ad-infinitum.
Now how do we get a resolution to the problem?
W-ith My 510 so can anyone suggest what do I do , I have poked around but coudnt find the Nvidia related power sets.
