To Clean Your Computer - HP OmniBook 6000 Reference Manual

Using Your Computer
Taking Care of Your Computer
Unplug the ac adapter when the computer is not in use.
To preserve the life of a battery, be sure to charge it regularly.
For long-term storage, the battery must be charged 20–50% to minimize capacity loss
by self-discharge and to avoid deterioration of performance. Storing a fully charged
battery can cause higher self-discharge and reduce its discharge capacity—even after
recharging—as compared to a battery stored when charged 20–50%.

To clean your computer

You can clean the computer with a soft cloth dampened with clean water or with
water containing a mild detergent. Do not use an excessively wet cloth, and take care
to keep water out of the case.
Do not use 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.
