Dear sir/madam,
The keys for brightness are not working but the other keys(volume,.....)are working fine ,so i have a problem with just the brightness keys. Also, brightness adjustment not available in control panel as well or anywhere else in any setting of the laptop. I have an hp pavilion x360 convertible 14-dh0xxx laptop with processor: Intel(R) Core(TM) i3-8145U CPU @2.10 GHz 2.30 GHz. Please provide a solution ?
