Malware, viruses and system corruption can cause a computer to run poorly or not boot. The IBM/Lenovo Thinkpad 61 laptop computer comes with a one-button utility called Rescue and Recovery that lets the user back up important files or the entire hard drive, restore backed up files or a full disk and restore the computer to factory-default settings. The utility can be accessed from within Windows or from a Pre-Operating System Environment if Windows will not load. Warnings Writer Bio
