HP Laptop has started flashing every few seconds between bright and then dim - screen always readable but flashing is very distracting. Is this likely to be a hardware fault or could it be something that can be corrected with the software?
Probably faulty backlight or inverter but you could try uninstalling and reinstalling your graphics drivers to see if that makes any difference.
