[RootbeerKid01]

My Lenova S21e-20 laptop screen changed to white while I was completing college course assignments. The following morning when I turned it on it still has this white screen. I don't know what to do. Please Help!

A white or blank screen could possibly be caused by a few different things.

That said, the most common cause is a loose video cable. The video cable can sometimes be pinched where, it runs through the hinges, and this can cause the connection to loosen. You may only need to reseat the cable. I would try that first. If this keeps happening, then the cable may need replacing.
