Often when a system has a virus or other type of malicious program, safe mode is the only way to locate and delete the problem. In safe mode, only the computer's essential programs are enabled, and only the files necessary to running the system are in use. Learn how to start an IBM Thinkpad T43 in safe mode using a few fairly easy steps.

1.Close all programs and restart the IBM Thinkpad T43.
