I've had a touchscreen X1 Carbon for >1 year now (specific model/year number is unknown). Throughout Windows 8.1 and now Windows 10, the brightness changes spontaenously and unexpectedly.
The screen will be normal (at my required brightness), dim, remain dim for a while, then brighten again to original point after an expected amount of time or if I manually increase the brightness.
I disabled auto brightness.
I disabled the light sensor (uninstalled it in device manager).
I manually adjusted the Intel driver settings so the brightness was set at maximum; still no help.
This occurs regardless if laptop is on battery power or plugged in.
This is a perpetual issue, occurs randomly.
I'm sick of this and am considering giving up the X1 to get another laptop. Any ideas?
