Windows 7: How to set Advanced options in Power Options (64 bit Ultimate)

I have an older Belkin F6C1500-TW-RK UPS and the mfg has not offered software management for the Win 7 64bit OS. I want to let Win 7 manage the battery and shutdown. I set the High Performance under Power Options to turn off display and put the computer to sleep after 3 minutes as a test. I yanked the input to the UPS and nothing happens and I went at least 5-6 minutes (didn't time). The battery icon in the sys tray stated 2 minutes remaining and never moved.

I have connected the UPS via USB and the Device and Printers, USB Input Device show the drivers are fine and the UPS is working.

Am I misunderstanding what Win 7 will do on its own without mfg monitoring software?

The attached are screen shots how I set the advanced settings

Welcome to 7Forums!

With those options, you can set how much time windows will take an action after you are not taking any action
So if you set 3 minutes for turning off the screen or going to sleep and leave it alone it will scedule these action after 3 minutes.
I don't really understand the part where you explain that the timer stopps. I do not recommend setting the same values for both options under 'on battery' or 'plugged in' state.
I would just increase the 'on battery' / sleep time to 5 or 10 minutes and see if it works.

Cheers!
