Comments on: When “smart” technology is dumb: a lesson in Intel graphics power-saving features http://www.istartedsomething.com/20090723/lesson-intel-graphics-power-saving-feature/ All the stuff about Microsoft and technology you haven't read anywhere else.

I suffer from exactly the same thing on my Acer Aspire 5742 running Windows 7 Home Premium. I go into the graphics driver, select "On Battery" and switch off "Power saving technology". That works for the current session but I have to do it EVERY TIME I reboot. I've searched on the web (and in the registry) in vain for a setting that will permanently disable this option. How can programmers mess up something so basic?? This problem seems to be even WORSE than described. I suffer from exactly the same thing on my Acer Aspire 5742 running Windows 7 Home Premium.

What I don't understand is why the display would be dimmed (and contrast reduced) when the items being displayed are darker and lower contrast. That is precisely the time when you need maximum contrast. Instead, the display becomes bright and high contrast when I have a bright, high-contrast window on the screen -- precisely the time when it would be ok to dim the lights a bit. I wonder if some Intel engineer didn't get the sign reversed somewhere in the driver. Thank-you for this fix.

Interested in disabling this on a number of machines under my command. Anyone know of a registry key that may do this? I've already tried running proc explorer to see what changes are made when the function is turned on and off, but I cant seem to find anything useful. Thanks for the article.

Especially when plugging/unplugging the AC charger. Did you find a solution yet? If so, please let me know. You're right, there isn't a checkbox that I can uncheck anywhere! Help! Hey Vlad,
I’ve got the same problem, with the same Intel graphics and media control panel. Especially when plugging/unplugging the AC charger. Did you find a solution yet? If so, please let me know. You’re right, there isn’t a checkbox that I can uncheck anywhere! Help!

This is my first experience with Win7 and I'm getting the same problem. When I unplug the AC cord, I get a black screen and it changes from 60hz to 40hz, and when i plug it in the opposite happens. How do I turn this off? I have an HP dm4-1165dx, and the Intel control panel is called the Intel Graphics and Media Control Panel. Any info would help. I've been struggling with this for 2 weeks now, and it's too late to take it back, besides i love the laptop. Help! Thanks. Please help!
