Replacement Procedures
Replacing the Real-Time Clock (RTC)
The STARION Desktop PC computer RTC integrates a battery with the computer clock and retains any
setup information when it is turned off. If the computer ever fails to retain the correct date, time, or
configuration settings when it is turned on, the computer’s RTC must be replaced.
To replace the RTC, perform the following:
♦
Record computer configuration settings using the BIOS Setup utility.
♦
Turn off the computer, disconnect external devices, ac power and monitor power.
♦
Unlock and remove cover.
♦
Carefully extract old RTC from socket.
♦
Install new RTC.
♦
Replace and lock the cover, connect external devices and restore power.
♦
Run BIOS Setup utility to reconfigure computer using recorded configuration settings from step 1.
Refer to ”BIOS Setup Utility”.
CAUTION
Make sure pin 1 on RTC is correctly aligned with location on socket (Figure 3 - 18, A).
Incorrect installation can cause faulty computer operation.
