    i have the same problem but i believe its not the problem with the button because it automatically goes into the brightness bar instead of going thru the main menu.

Your button is stuck. If it is stuck on the external button, try plying it forward with a needle, if it is broken internally, a technician can fix the switch on the board for you.

CCFL are back lamp tubes. for the SCREEN
CQ58-nnn what, what it the full service tag Partnumber.
ill toss the 50 sided coin and land on cq58-100
the 100 model, is LED and not CCFL lamps
so what OS is running? Windows 7?
i yes, see the users guide on bightness.
read page 26
the magic F3 key.
if the key fails, that means, the drivers loaded on this pc are wrong.

correct drivers are alway here at REAL HP (we are not hp)
im picking w7-64bit now, if not 64bit go back and change that first.

No way to adjust screen brightness


Hello, It is possible to adjust your brightness from your graphics settings. most likely there is a graphics icon located with the icon collection (show hidden icons) by your clock. Hope this helps Good Day

I have my compaq presario cq60 laptop and i got a trouble on my screen which is the brightness become low and i can not adjust using the fn key plus f8. how can i adjust to return on the normal...


How low has the brightness gone? If it is very dark and you can barely see anything on the screen, it may be that the inverter board has failed and needs replacing.

The problem could also be caused by the screen itself, or the motherboard, but the inverter is the most common solution.

I would like to reduce brightness on my ASUS VH242H


Actually, the problem isn't with the drivers. Right click on the battery icon in your system tray. Select "Power Options" (NOT Power4Gear eXtreme). On the right panel, select "Adjust the display brightness." Then, select "Change advanced power settings." Scroll down and open up the "Display" box. The options that are affecting your screen brightness on battery are "Allow SmartDimmer to reduce my brightness after," "Have SmartDimmer reduce my brightness by," and "SmartDimmer full-screen video mode." Playing with the percentages in these boxes will affect how your screen brightness adjusts itself. To get my screen to stop re-brightening itself, I changed "Allow SmartDimmer to reduce my brightness after/ On Battery:" to 100%. I then changed "Have SmartDimmer reduce my brightness by/ On battery:" to 0%. Finally, I set "SmartDimmer full-screen video mode/ On battery:" to Maximum Power Saving. This should solve your screen-rebrightening problems even with the 163.44 drivers (I use those too). Please Rate.
Thanks, Anand Fixya
