A new laptop doing this is a warranty call.
An old laptop doing this is you undoing changes you made or using System Restore to when it worked and if that doesn't work, a factory reset.
Ello. I need help with my HP Envy (I think) lab top. When I go on the internet and leave it alone for a few minutes (like,3) it completely shuts itself off. This doesn't happen if its on home-screen or im playing a game or watching a video. The power plan is set to high performance and its plugged in. It is set too power off/ dim screen after one hour.
