Saw your thread on another forum about this here.

Did you ask your neice if she tried to install any programs or what web sites that she visited? Sounds like you may have a boot sector virus, or she tried to install something that messed the system files.

What make and model laptop is this? If it is a new one, the battery would be fine.

...and it worked fine before you let her use it?
