By default the power config is set to balanced which reduces the screen brightness. It seems that both Vistra and Windows 7 think the touchsmart are laptops. Go into the power configuartion control panel and choose "show additional plans" and choose "High performance". In addition to the brightness, you will also notice a slight overall speed improvement.

Woohoo! I won my Touchsmart!

Tried adjusting power options and display settings. Brightness still resets to approximately 75%

You have to go through all the clicks as I stepped by step in my last post, and save a profile by going over to the sidebar on the left of the "Power Options" window you are in, and click on "Create a power profile", mine stays at 32% or where ever I set it at, it's saved as a file on the disk. The brightness goes up in "octaves" every 8% you adjust it, so there is no difference between 39% and 28%. The brightness only responds at multiples of 8% ( 0% 8, 16, 24,32, 40, 48%,etc. ) until it goes from 96% to 100% in only a 4% increment as the last stepping of brilliance control. I'll edit that post to reflect the part about saving the settings in a new profile if need be. Sorry for the omission.

I have the same problem. Tried everything but once the computer comes out of sleep mode or even after the screen comes out of sleep mode the brigtness is reset to the brightest setting. I have tried saving under multiple profiles but nothing seems to work. Very annoying. Any help appreciated.

I have a same problem too in my Touchsmart 300-1058hk...

i had the same problem,
problem was caused with the power setting as davetn said,
since i changed to full power never had any problems since

Kristine,
I went into power settings and changed the power saving brightness to 99%. So while I'm using my computer its at 100% and if it sits idle, it drops back to 99% rather than the default 50%.

Heres how: Control panel > Power Options > Choose the power settings that you are on (I'm on High performance) and select "change Plan settings". Then choose "Advanced Settings".

From there a dialog box will open. Scroll down to display and click on the + sign. For Display brightness, choose 100% and for dimmed brightness, choose 99% and then click on "apply".

You should be good to go from there.

Woohoo! I won my Touchsmart!

mine is doing the opposite of you guys (might be the same fix though)

for the last two days the screen brightness has been dimming from 100 to 0.

it used to to dim after 5 minutes and then turn the display off at 10min. now when returning to the computer and turning the display on the brightness stays at zero.

i went to power options and the settings are default so nothing has changed. just have no idea why it's doing this all of the sudden!?

mine has done the same thing since i bought it-even reformating does not do any good for the brightness. It stays bright and after I change it, it changes back to 100%by itself after it has slept or been restarted.
Has anyone figured out what to do about it. you can talk all day long about it, but that gets nothing done.
