Power and Battery Problems
If the OmniBook turns off immediately after it turns on
•
Battery power is probably extremely low. Plug in the ac adapter, insert a new
charged battery module, or insert a secondary battery in the plug-in module bay.
If the OmniBook keeps beeping
•
The OmniBook beeps for 15 seconds when the battery is low. Save your work,
quit immediately, and insert a charged battery or plug in the ac adapter.
If the OmniBook has a short operating time
•
Try conserving power using any of the suggestions listed under “To save battery
power” on page 3-9.
•
If you are running any applications with an automatic save feature, such as
MS Word for Windows, disable this feature.
•
If the operating time has gotten shorter and the battery is more than a year or
two old, you may need to replace the battery.
•
Turn down the display brightness (Fn+F1).
•
Heavy modem use can affect battery operating time.
•
Check the Power Management settings in BIOS Setup.
1. From the Start menu, shut down, then restart the OmniBook.
2. When you see the HP logo, press F2 to enter the BIOS Setup utility.
3. From the Power menu, make sure the Power Management Mode is set to
Maximum Power Savings.
4. Press F10 to Save and Exit the BIOS Setup utility.
If the battery doesn’t charge
•
Make sure the ac adapter is plugged into the power source.
•
If you’re using a power strip, remove the ac adapter from the power strip and
plug it directly into a wall outlet.
•
Check that the light on the ac adapter is on.
•
Check that the battery is fully installed and locked in place.
