problems:
v Lenovo ThinkVantage Toolbox or Lenovo System Toolbox, depending on your
operating system (used when you are running the Windows operating system)
v PC-Doctor for Rescue and Recovery (used when your Windows operating
system does not start)
Notes:
1. You can also download the PC-Doctor for DOS diagnostic program from
http://www.lenovo.com/support. See “PC-Doctor for DOS” on page 65 for

diagnostic programs, save and print the log files created by the diagnostic
programs. You will need the log files when you speak to a Lenovo technical
support representative.
