Adjusting Brightness
Sep 13, 2009
Well i've read couple of threads about adjusting LCD brightness in windows vista. I've a vista retail CD so before instaling it, i have a question.
My laptop is TOshiba Portege M700 (nothing to do with my question but anyways)I've problems adjusting the brightness. I've tried couple of things but nothing so i came to a decision of installing windows vista.
I also have a sticker next to my touch pad saying Windows Vista certified something. So i wa wondering if i install it, will i be able to adjust my LCD brightness through a program in vista?

I have an issue with screen brightness... Using FN and F10 does not increase brightness (swap FN with CTRL is disabled in my bios - FN is FN) The screen brightness indicator when I use the FN F10 key indicates the screen is at max brightness, yet at minimum there is no change in brightness. My ambient light sensor is disabled so I COULD use the FN key to adjust brightness I have reinstalled my chipset drivers, flashed my bios and tried damn near everything to get my brightness up. Currently, my brightness is at minimum, despite my power options saying its full and the onscreen indicator when FN is used telling me the same.
At bootup and in the BIOS I am able to adjust the brightness and it DOES get significantly brighter (and dimmer) when I use the FN keys. I have scoured the internet and have found nothing relating to my issue as of yet, hopefully someone here can help me out. Side note: I have a Compaq 8710w with Vista Ultimate x64 on it (yes, a legit copy) All windows updates are done, I have even done what I normally refrain from doing - installing all of the HP / Compaq base software garbage that they like to preload in hopes of remedying my issues with the screen brightness level....

It seems I have hit a wall on my particular CPU. I can easily get it dead stable at 3.2 GHz, with the RAM running at 1066 (rated specs) and manually adjusting the timings to 5-5-5-18, also spec. But if i start going any higher the system starts getting quirky - particularly when I resume from standby - it goes south with a BSOD. Gunter, I know you wanted pics, but let's keep it all consolidated in here and start keep it to a relative few people.

Just developed a problem with the screen brightness on my Laptop. When I unplug from the mains it dims, as normal but it will not brighten up again until I reboot with it plugged into the mains. Plugging the power back in doesn't work the brightness controls don't work, disabling auto dimming doesn't work.

Have Vista HP on a Dell 1525. When I play a WMA file, adjusting any of the video settings slider controls has no affect on the quality of the video playing, not even if I adjust the settings before clicking 'Play'. When I play mpg files, however, adjusting the settings DOES result in the video quality being changed corresponding to the whichever setting is changed. What I can I do to solve this problem when playing WMA files? Is there some setting I need to amend or do I need to download a file/codec?

i've been trying the windows 7 (x32/x64) and other flavours of vista (x32/x64) for the last 6 months while gaming at HD res all the time and there was never an issue. So the problem is that anytime i open up windows task manager or any other adjustable window and i try adjusting the window(includes maximising and minimising) the Cpu usuage just bursts up to roughly 45%. Like in many previous threads i'm already familiar with the red line showing kernel times in task manager and i did notice that 3/4 of the cpu usage bar (when it rises is red: meaning more kernel usage). Also i hear a funny noise near the cpu area. It is definitely the CPU. For some it might be that i'm too fussy or something but this did catch my attention specially while playing games like Racedriver GRID for example where it started to run slower specially at HD resolutions when it wasn't few months ago.
Here's what i've been trying:
1)I've re-installed windows(tried XP Pro x32,Vista Ultimate x32/64, 7 x32/64) and after each installation even before installing any drivers whatso ever the problem was there by going to task manager and trying the thing(ie holding corner of task manager and scrolling and seeing cpu/kernel usage go upto 40 % for nothing)
2)Reformatted and doing the above.
3) Used another power supply in case mine went wrong or something( Used HIPERPOWER | Type M | HPU-4M880)
4)Took all hardware out one by one in order of less importance and booting up to see if problem was still there. (took out DVD DRIVE since there were threads reporting it as the culprit, did also remove sound card etc..)...........

When adjusting my volume by clicking the speaker in the tray it used to give me a sample ding after I moved the slider and let go of it. Now it's silent.
It had me thinking I had a no audio problem until I played a music file.
I went into sounds and looked for a reference to the conmand to see if there was no sound assigned but cannot figure it out.
