Why is my laptop constantly going into sleep?

Hello, I have an ASUS laptop (N53Jq, i7, GT425M, 8GB) with Windows 8.1, with update. It's being used like a desktop computer, with the lid closed connected to a monitor through HDMI and with mouse and keyboard. I have the Power4Gear Hybrid driver, to set the high performance mode in my PC, but after awhile it still goes into sleep mode (like 1 or 2 minutes). It's really weird, I checked every setting (on the driver app and control panel) and sleep mode is off everywhere. What could be wrong here?

Thank you for your time.

I would try ASUS forums as the readership should be dominated by ASUS owners. I have a Toshiba Laptop. The only thing I can guess as a shot in the dark would be if you possibly have Adaptive Brightness enabled? That's the only thing I can thing of that reacts in so short a time.

power settings

Hi Kratos,
have a look at your power settings ASUS uses its own power options program, also check the settings on the MS power option too, they might be in conflict see screenshot, note i have removed it on my asus laptop(X55a) and only use MS's as shown. note also check your hibernate after XX mins

Thank you for the suggestions, guys.

Like I said, I checked every setting there is (MS and ASUS app) and no conflict. Closing lid is set to do nothing, with or without battery. It's also set to not turn off screen or sleep, no matter how much time goes by. I didn't want to unninstal the app because it's high performance mode is pretty good and manageable, I never had issues with it before, but I guess if this problem persists i'll try and unninstal it.

Igot the impression he's running an external monitor with the Lid closed. If that's the case it should be set to Do Nothing.
