If the OmniBook doesn’t automatically hibernate as expected
•
For Windows NT, certain point-enabled PC Cards and possibly other cards may
prevent automatic hibernation when battery power is low. This may cause a drained
battery and data loss. When leaving the computer unattended, either connect the ac
adapter or shut down the computer.
•
For Windows 2000, check to see that hibernate support is enabled. From Control
Panel, open Power Options, and then click the Hibernate tab.
Also, check the Power Schemes tab. Make sure the Hibernate time-outs for both ac
power and battery power are not set to Never.
If the battery doesn’t finish charging in an external charger
•
If you charge the battery in an HP external battery charger, the battery is finished
charging when the charger’s orange light turns off. It doesn’t matter whether the
green light turns on or stays off—the battery will be at least 90% full.
Printing Problems
Hint For most printing problems, click Start, Help and use the Print Troubleshooter. If you’re
using Windows 2000, click Start, Help, Troubleshooting, and Print.
If a serial or parallel printer doesn’t print
•
Check that you are using a proper cable or cable adapter, and that the printer is turned
on.
•
Check for paper in the printer or other printer errors.
•
Make sure the printer cable is secure at both ends.
