I got a Lenovo ThinkPad T480s a few months back and have been having this problem since.
My laptop locsk out and the screen goes blank all of a sudden. I could be surfing, writing an email, working on Ms Office or doing other operations.
I have to then press the power button and unlock my laptop. I do not loose any work but this keeps happening very ferequently. When it does occur it keeps repeating a few times till it normalises.
Any help will be appreciated.
