Re: 4540s brightness function key is not working

The brightness hotkey requires the "real" video driver be installed, and not just the "default" Windows driver. What Windows version are you using?

Re: 4540s brightness function key is not working

i have two laptops HP 4540s and HP2000.

in both the laptops all other hotkeys are working but only the brightness control key is not working.

 

i am using windows8 professional 64 bit.

i downloaded the driver from hp website for HP 2000:

http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareIndex.jsp?lang=en&cc=ch&prodNameId=5368063&...

 

but even after downloading the graphic and touch pad software/driver from the above website the brightness key is not working. Same  problem in both the laptops.

Pls send me the link from where the driver is to be downloaded and the step by step process to finish it.

 

Looking forward to receive from u at the earliest.

 

Regards,
