When I first did this, the problem was that due to the power going on and off repeatedly, my computer wouldn't boot in the morning when I got up.   I had no idea what to do, since I couldn't even get into the bios or run my system image restore disk, it was completly dead.
I called the company (Falcon Northwest) and told them what was happening.  They said the master boot instructions had probably been corrupted, since the computer wasn't on at the time.  And that draining the power would cause it to replace the corrupted instructions.
I was somewhat skeptical, but I did it.
To my surprise, the computer booted right up the next day and worked fine.
Yesterday I just did it since I couldn't find anything else that would get it to work, to my surprise the computer booted up with the video working.
I really honestly didn't think it was going to do anything.
