To Get The Most From Your Batteries; To Clean Your Computer - HP OmniBook XE3 Reference Manual

To get the most from your batteries

Do not leave batteries unused for long periods of time. If you have more than one,
rotate them.
If you normally use AC power, make a practice, at least once a week, of using the
battery as your power source.
Unplug the AC adapter when the computer is not in use.
To lengthen the life of a battery, be sure to charge the battery regularly.
For long-term storage, the battery must be charged at 20–50% to minimize capacity
loss by self-discharge and to avoid deterioration of battery performance.
For a model with a dual-speed processor, use the lower speed on battery power (see
"To control the processor speed" on page 52). The default settings conserve battery
power.

To clean your computer

You can clean the computer with a soft cloth dampened either with clean water or with
water containing a mild detergent.
Do not use an excessively wet cloth or allow water inside the case.
Do not use any abrasive cleaners, especially on the display. Do not apply any cleaner
directly to the display. Instead, apply the cleaner to a soft cloth and then gently wipe
the display.
You can clean the keyboard with a vacuum cleaner to remove accumulated dust.
