sims 4 keeps putting laptop into sleep mode while playing
I can play Sims 4 for about a half hour then the screen goes black and the laptop goes to into sleep mode. I hit the power button and things resume. To the touch, the laptop has no hot spots on the top nor bottom and the laptop is sitting on a cooling tray. There is nothing set that would make the laptop regularly go into sleep mode (in other words, it is on 24/7 and it never goes to sleep. I checked power plan settings, usb settings, cpu and video card settings, and so on. :Laptop is an HP probook with 16 gigs of ram, 150 gigs of free drive space, and an i5 processor. I am at a loss. Speedfan shows the cpu temp to be within normal. I can't figure what is causing the laptop to go into sleepmode. I uncovered everything I could and blew it out with an air compressor. I got a little dust but that has not fixed anything. If I just launch the game and let it sit, the laptop goes to sleep within 10 minutes. I can't figure this out!
Suggestions would be appreciated.
