My own thoughts would be to remove her hard drive, slave it to another computer, do a malware scan on it once it is powered up and then copy her data to the second computer, 'Caddies' which allow 21/2" hard drives to connect to other computers as external drives are readily available if you don't have one. Once you have backed up her data - and that's the stuff that matters - you can go ahead and attempt to repair the computer.
Can you get into the 'Safe mode' screen by tapping F8 at the BIOS screen instead of going to Recovery Manager ? This might enable you to sort the problem without doing a complete re-install of everything, perhaps by using a restore point ? This would save you having to uninstall all the manufacturer installed software that you don't want as well as having to do all the updates from the time of the French Revolution.
I have just re-read your post and you say 'She has her battery pulled out.' Do you mean that she has removed the battery since this happened, or that she didn't have the battery installed at the time she moved from one room to the other ? That would imply that she would have had to disconnect from the mains before moving. If she didn't shut down the computer before pulling the plug out of the wall that could have this effect, but if you can access a Windows restore point you should be able to fix it without doing a complete system restore.
