I have a brand new E520 and I love it. But there's a quite annoying problem with the screen: it tends to change brightness (it gets brighter or darker in 3 or 4 steps). Could anyone tell me how to fix this?

Hi there, I have a 6 week old E520, I'm having the same problem (kinda) as you, when Ii reduce my brightness form 15, it reduces normally until 2, but from 2 to 0 the brightness suddenly increases dramatically (brightness @0 = brightness @10). This never used to be the case until about 4 days ago when this problem started. Please could yo advise which driver to re-install etc?

Have the same problem with a new E520 machine .
There is an unofficial workaround posted in the forum
It involves changing the driver to Intel's newest.
Perhaps someone from Lenovo can inform us when will it be corrected.

Have already recieved my E520 from service center for this issues. They said that it's the power management profile problems. I don't really understand what they mean. Is there any lenovo staff who can explain this issue for everyone?

Problem is solved! Run system update and install the latest ThinkPad video features. V22.214.171.1246
Installed but not solved completely. The brightness still goes up and down but in less level and less frequency. It occurs more frequent when the battery under 18% (40 minutes left).
