Next. I have a Lenovo 3000 C200 and I want to restore it to the factory settings the manual says to turn on the computer and press the lenovo care button and there will be an option to restore your system to factory settings, I assume this is the option that is to diagnose hardware or recover your system, so...ow am I suppose to restore to factory settings? The laptop did not come with a recovery disc because it is suppose to already be preinstalled on the hard drive. My computer really needs to be restored to factory settings because it has that many problems I would rather just start over with it.
