I have an i7 920 pc, which is a power hog as u may know. Now i am on a broadband plan (dataone home 500) that gives nighttime unlimited downloads (2 am to 8 am). So i have scheduled my pc to starton and download (via utorrent) in that time. But keeping my pc on for 6 hours every night has increased my power bills significantly. Is there any way to run my pc in the absolute low power state possible just to download during nighttime and get back to full power state in the day ? Without any hardware modifications and only through software ? Any suggestions ?
