Power and Power-Up Modes
Before you remove the battery pack, save your data and shut down the
computer, or place the computer into Hibernation Mode. Please be aware
that, when placing the computer into Hibernation Mode, the contents of
memory will be saved to the hard disk drive, although for safety sake, it is
best to also save your data manually.
Real Time Clock (RTC) battery
The Real Time Clock (RTC) battery provides power for the internal real
time clock and calendar function and also maintains the system
configuration while the computer is turned off. If the RTC battery becomes
completely discharged, the system will lose this information and the real
time clock and calendar will stop working - in this instance the following
message will be displayed when you turn on the power:
S **** RTC Power Failure ****
Check system. Then press [F2] key.
You can change the Real Time Clock settings by turning the computer on
while pressing the F2 key and then release the F2 key when the Qosmio
logo screen appears. Please refer to Chapter 9 Troubleshooting for further
information.
