What should I do if my computer screen flickers or fades to white? (Intel graphics accelerator installed models)
Depending on the model you purchased, the computer screen may flicker or fade to white when the power saving
function is enabled and the computer screen switches.
To avoid this, right-click on the desktop and select
Graphics Properties to display the Intel graphics control panel,
and then disable
Display Power Saving Technology under Power. If you select On battery, the setting
screen may appear.
Note that the battery life becomes short if you disable this setting.
