Achieving optimal screen brightness on an HP Compaq nx6110

by smiledoctor / June 22, 2005 3:58 PM PDT

Please help me.

I just recently purchased an HP Compaq nx6110 with an Intel Graphics Media Accelerator 900. My laptop has a 1.6 ghz Pentium M Centrino processor, 512 mb ddr ram and 60 gb hard drive.

Whenever the laptop is plugged to a power source, the screen has acceptable brightness.

When the laptop is unplugged and runs on battery power, the screen becomes noticably dimmer. Images on Power Point presentations loose their sharpness and appear washed out.

I do not have the luxury of having a power outlet beside me whenever I give powerpoint presentations so this dilemma really bothers me. I've tried adjusting so many settings in the Intel Graphics Media Accelerator Driver menu but to no avail.

Am I right, the trade for the 4 hour battery life of the Compaq nx 6110 laptop is a dimmer, less vibrant screen when the laptop is unplugged?

Is there a way to fix this? My brothers 2 year old Compaq Presario 2100 2 ghz Celeron laptop has a much brighter screen than my brand new laptop.

I have the Compaq r3000.

There's a menu somewhere to boost the brightness while on battery power. I don't have the r3000 out at the moment but remember seeing the menu.

I finally fixed the problem

Thanks for the reply Bob.

After some research and chatting with HP's online help service, I found that by pressing fn f11 I could disable the ambient light sensor of my laptop ( so that it doesn't dim my screen anymore while running on battery power).

By pressing fn f10 I was able to increase the brightness to acceptable levels.

I think the purpose of the ambient light sensor is to prolong the battery life to 4 hours. For my purposes, I'd gladly sacrifice battery life for screen brightness, particularly when I deliver presentations.

Hp also suggested I change the power scheme settings in the control panel to match my current needs.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
