Why does my screen keep locking every two minutes or so?

Solution 1:

After searching around for a while I stumbled across this:

"I think I finally found the problem. There's a setting called "System unattended sleep timeout" However, in Windows 10 it does not show up in the Advanced Power Settings.

I had to add it through a registry edit from here (the Windows 7 regedit works on Windows 10) http://www.sevenforums.com/tutorials/246364-power-options-add-system-unattended-sleep-timeout.html

So far it has not gone to sleep after two minutes when I wake it with my mouse.

So, it looks like a Microsoft problem, not hardware." by CaesarMagnus

After changing the registry using the link he provided, I was able to change that setting, and it fixed my issue. Hope that helps.

Solution 2:

I know this is strange, but do you happen to have any finger print drivers installed? I read an article online, saying the Lenovo finger print driver has been causing some issues with the power settings.
