If power surges or sags, the display and status lights may flicker, and the Notebook may
automatically restart. If an improper shutdown occurs, the Microsoft Windows utility program,
ScanDisk, runs automatically once power is restored. ScanDisk determines whether the improper
shutdown has caused any errors on the hard disk. These errors may occur if the Microsoft Windows
operating system is not able to close all files correctly before the shutdown. If no errors are found,
the restart process continues. If ScanDisk does detect errors, follow the instructions on the screen
to continue the restart process. Work or information that was not saved before the loss of power or
shutdown may be lost.
If a power failure occurs, or if the power cord disconnects while the Notebook is turned on, turn it off
until normal service is restored. The next time the Notebook is turned on, ScanDisk may run to
check the hard disk for errors caused by improper shutdown.

Increasing Battery Pack Operating Time

Battery pack operating life is affected by several variables. To avoid unnecessary replacement,
consider the following when determining how long a charged battery pack should last:
Power conservation settings
•
Hardware configuration
•
Software applications
•
Installed options
•
Display brightness\\Server\projects\Compaq_Port\Portable TimesheetHard drive usage
•
•
Changes in operating temperatures
Type and number of installed PC cards
•
Note: Power consumption requirements for PC cards vary widely. Some cards drain the
battery pack very rapidly.
Battery pack operating life can be increased by as much as 50 percent by controlling the energy
required by the Notebook and the energy stored in the battery pack.
Minimizing the Energy Required
To minimize the energy required by the Notebook, follow these guidelines:
Set the power conservation levels in the Power Management utility to Maximum.
•
Customize the time-out value to work more efficiently with the applications. The length of
•
battery life depends on the values selected.
