HP dv6 7010tx : erratic screen brightness

by Granshk / June 17, 2012 7:30 AM PDT

Just got my HP dv6 7010tx laptop and i've noticed that the brightness of the screen changes when I alternate between dark and light backgrounds.
It happens exactly like the way if brightness is adjusted manually, there is usually a 2-3 step increase/decrease and then the screen settles down. I tried few driver updates but that too din't help...
This doesnt happen when its plugged in.
Also when the screen turns on(after being off due to inactivity) there is a two step increase in the brightness and this happens even when the charger is plugged in.
Any idea what the problem is???

You said "This doesnt happen when its plugged in".

I assume you mean plugged in to the mains, and not using it just off the battery.

If so, I am guessing this is a feature of running it off the battery to save battery power.

faulty battery replaced, problem still there...

I thought so, but havn't been able to find the exact feature which controls this. The HP tech guy even got the battery replaced(had lower charge capacity than its should be for a new one) but still the problem is there.
Plus this happens when screen is turned on every time, regardless that it is high performance plan or plugged in, on the other hand the change in brightness due to varying dark and bright background doesn't occur when it is being charged or on high performance mode.

thanks for the reply

check your Power Options in the Control Panel.

My Packard Bell laptop does this when the mains is not plugged in and it is running just off the battery. I get a pop up message from the Notification Area, (where the clock is), telling me that it is cutting power consumption until it is needed, and this happens soon after I boot into Windows.

Go in Power Options click change plan settings then click change advanced power settings then scroll down and go to Graphics Power Settings
