RE: Brightness Control on Inspiron 14R(N4110)

Hi Raju,

I would suggest you to update the BIOS, chipset and then quickset driver on the system in sequence for issue resolution. Please enter your service tag # on the link below, select the OS, then download the BIOS from BIOS section, chipset from chipset section and Dell Quickset application from Application section onto the system and install it.

In Addition, I would advise you to open ‘Power options’ screen and adjust the screen brightness at the bottom of the screen to check if it works.

Please let me know if this helps.
