Question about IBM Thinkpad T20 Notebook
These error message relates to the BIOS and it appears the BIOS battery requires replacing because it is flat.
error 161 usually BIOS has lost its configuration/ checksum error.
error 163 usually BIOS clock not updating.
Replace this battery and go into the BIOS setting and configure the date/time settings, and hardware settings (if you are not sure select the factory default settings) save and exit
