display dims and brightens by itself?

2010-04-17, 4:33 AM
i bought the edge about 2 hours ago. im setting everything up with level 2 brightness. and the screen seems to be dimming and getting brighter on its own... within one to two levels. is this a malfunction or some kind of advanced power saver function? has anyone else experienced this?

I noticed on my display that it had different preset modes...and when it did this, it was because it was set to dynamic contrast mode.

 

Not sure if you have the same display or not.

I had the same issue in the hours after receiving my 14" Edge.  I put up with it for 10 minutes  before deciding I may as well do a full system recovery.  This was 7 days ago and I haven't had any issues w/ the extreme auto dimming.

Check the Power Management settings in the Windows Control Panel first under Advanced Settings.

Then check the additional proprietary settings in the Lenovo ThinkVantage Tools > Power Controls > Global Power Settings. There are options to dim the display during certain events like logging in and shutting down, etc. These are additional supplements to the Windows settings.

I have this same issue on my Edge 15.  The screen will suddenly dim for no apparant reason.  You can see the brightness stepping down.  It steps down in smaller steps than the F7 / F8 brightness keys, but it steps down the brightness a lot.  Then for no apparant reason it will step the brightness back up to where it is supposed to be.  The brightness meter isn't affected.  When it is dimmed down, the brightness meter will still be on 15. ... and it doesn't just dim, it kind of gets a washed out look.  It makes me feel like I'm about to pass out.

 

I went through the Windows power settings and the Thinvantage global power settings, dynamic brightness control.  None of the dynamic settings are checked.

 

It doesn't seem to matter if it is plugged in or on battery.

 

Anyone else having this problem?  It's pretty weird and I don't understand it.  And it's pretty annoying.

Mine does this too!  It goes very bright and later dims without the brightness numbers changing.  At first I thought I'd been working for too long and my eyes were playing tricks on me, but it happens several times a day.  Has anyone figured out why this happens and how to fix it?
