MSE Scheduled Scans not working

[Gadsdan]

I have my Microsoft Security Essentials set to scan every week. It keeps failing to do so and giving me a warning that I haven't run a scan in a while. I require the computer to be on, but in use is okay. Does it not consider "sleep" on?

Okay, that appears to say it cannot be in sleep mode or the scan won't start. I'll try scheduling it when the computer is not in sleep and see how that goes. Thanks!
