60 Operating Manual T X100 S2
Troubleshooting and tips
7.6 Incorrect date and time
Ê Set the date and time in the operating system or in the BIOS Setup under 
the Main menu, using System Date and System Time respectively.
I Note that the operating system may affect the system time. For example, 
the operating system time may deviate from the system time under Linux, 
and would overwrite the system time in the default setting on shutdown.
If the date and time are still wrong after the server has been switched off and 
back on again, replace the lithium battery (for a description refer to the Technical 
Manual for the D2779 system board) or contact our customer service team.

configuration program.
I For more information on configuring the controller, see section 
"Configuring the onboard SATA controller" on page 51.
