• Check that Cache is enabled (in the System Configuration Utility, open the System menu and check Enable Cache). • You might need to install more RAM. The memory-expansion boards are HP part numbers F1167A (8 MB), F1168A (16 MB), and F1169A (32 MB). If the battery runs down too fast • Make sure you charge the battery until the Status Panel shows a full battery. The charging light changes from orange to green when the battery is only about 90% charged. • Try conserving power using any of the suggestions listed under “To save battery power” . • If the operating time has gotten shorter and the battery pack is more than a year or two old, you may need a new battery pack.

If the OmniBook turns off immediately after it turns on • Battery power is probably extremely low. Plug in the ac adapter, or turn off the OmniBook, and insert a fresh battery—see “To replace the battery” .
