I recently got a new Lenovo A275 laptop. Periodically, the screen will freeze for a few seconds. Any audio keeps playing, so it seems like the CPU isn’t frozen, it’s just the display. Oddly enough, if I press any key on the keyboard, that usually sets things back in motion (otherwise the display remains frozen for quite some time).
Sometimes, neither mouse movements or key presses do anything, but audio still plays. I can either put the computer to sleep for a couple seconds, or close the top and turn off the monitor, either way, that fixes it.
Anyway, this issue is pretty annoying. Any idea how to fix it?
