i found that the frequency of dimming goes down significantly if the power plan is set to 'Maximum Performance' in the power manager.

Hi gbgoud,

 

Do check your configuration of Power Manager for the Maximum Performance profile. I've attached a screenshot of mine for your perusal.

As at the "Idle timers" section, you can see the settings for "lower display brightness" has been set to "Never"

Turning off Dynamic Display Settings

2010-10-05, 19:18 PM

I don't know how the rest of you feel about it, but I absolutely CANNOT STAND while I'm in the middle of watching / playing / reading something and the display decides to automatically dim and rebrighten. It is infuriating!

 

How do I go about PERMANENTLY disabling this hack-job feature?

 

I went into the Thinkpad Battery settings and under global / advance tab I made sure that NOTHING is selected under the Dynamic drop down list...but it STILL DOES IT.

 

Arghghhhhh

 

WORST FEATURE EVER

Hi Ishbar,

You could try uninstalling the Power Manager and see if it helps.

Hi infins,

Welcome To Lenovo Forums.

Kindly further explain when you press F8 once then the screen is as bright as you want or as bright as possible?

Also could you let us know what model of ThinkPad are you using as well. Also does this issue appear when you first bought your ThinkPad?

Re: Turning off Dynamic Display Settings

2010-10-22, 21:04 PM

I reinstalled the entire software suite as well as reinstalled Windows back to factory defaults.

 

This computer never ceases to dissatisfy me.

 

 

This was supposed to be a replacement of a poorly running ThinkPad, perhaps by coincidence or bad luck.

 

Instead I am slowly beginning to think that the Edge really is a bad consumer laptop and has no merits other than piggybacking the brand name.

 

I have emailed Lenovo the following but I feel I must exhaust all outlets as to ensure my dilemma is acknowledged and henceforth resolved:

 

The replacement ThinkPad Edge 14 variant has a number of software issues which are not resolved by system restore or OS re installation. I have fairly sensitive eyes, to light adjustments at least. There is a function on this machine which causes the display to either dim or illuminate depending on processor demand as to conserve power. Now this occurs in all power plan settings. I have accessed the software control panel for this function named "Dynamic Brightness." The issue here is that when I offset all the items, they still occur, only marginally less infrequent. Because of these quite often contrast changes I get headaches and thus must resign use.


Next the software does not function as it should. On screen displays sometimes hover and never fade, other times they will not load. This is regardless of system usage or plug in settings.


Lastly, and perhaps the most irksome of these affairs is that upon resuming sleep, the laptop may not power back the LED display. The laptop itself will be awake, and the OS fully functioning (as discovered with an external monitor) the display refuses to turn on. The only cure is to force shut down, so barring the availability of external displays, must force quit anything you are working on. This is a great hindrance because I use my laptop at multiple intervals throughout the day and during class. I can't keep shutting down and restarting between classes or every time I have to close the display for an overhead projector.


I find the culmination of these problems, withstanding it's replacement, to be a monotonous state of things. How many times will I have to get my products fixed? How much before enough is enough? Had I been aware of the cheap imitation this machine was I would have gone for something like a ThinkPad X or T400s. I am very displeased as a customer about all of this and quite exasperated.

Hi ishbar,

Could you try removing any 3rd party RAMs if you have them installed? Also could you do a BIOS default reset as well. Have you contacted customer service regarding this issue?
