My X100e screen brightness is increasing by itself

[larango]

It is interesting to see that when my X100e is connected to the power outlet, suddenly the screen brightness starts increasing by itself. It is like someone -not me- is pressing the bright-up key one step at a time every 2 or 3 minutes until the bar gets to 15.

I haven't spent time trying to understand when and how the behavior occurs. Only thing I have found regarding this issue is the following post at Lenovo Forums.

They way it was solved was by reinstalling everything.

Any of you experience the same problem?

I am running Windows 7 - 32 bits with Lenovo Power Management. My bios version is BIOS: 1.29 / ECP: 1.22.

You've not by any chance installed IE9 have you? That's when my problems with this started originally...

Nope. I am trying to recall what software installation might trigger the behavior. But I don't have any idea. In the last few days I am not experience the behavior. I remember I just installed a few windows updates lately -probably something fixed it?-.

I will try to keep posting on this issue if solved or not.

Bad news. Behavior still happening.

Also since I bought my self a new laptop to replace my x100e I won't be able to keep posting on this topic, unless my new machine experiences the same behavior.
