To Optimize Battery Operating Time - HP Pavilion N5402L Reference Manual

Traveling with Your Computer
Using Battery Power

To optimize battery operating time

• Plug in the AC adapter, especially while using the CD-ROM drive or DVD, the
floppy disk drive, or any external connections such as a PC card or a modem.
• Put the computer in standby mode whenever you are not using it for a short while:
click Start, Turn Off Computer, Stand By.
• Put the computer in hibernate mode whenever you want to save your current session,
but will not be using the computer for several hours: click Start, Turn Off Computer,
then press and hold Shift and click Hibernate.
• If you have an I/O PC card—that is, a PC card having an external connection, such as
a network card—remove it when you're not using it. Some I/O cards use significant
power, even while they're inactive.
• If you work with an application that uses the serial port or an I/O PC card, exit the
application when you have finished using it.
• Turn off the CD player when you are not using it.
• See "Managing Power Consumption" on page 50 for other ideas about reducing
power consumption while the computer is not in use.
