If the battery doesn’t charge

Make sure the AC adapter is securely connected to the power source and the notebook, and that the light on the adapter is on.

If you're using a power strip, remove the AC adapter from the power strip and plug it directly into a wall outlet.

Make sure the battery is properly installed and locked in place.

Move the notebook away from any nearby heat source. Unplug the AC adapter and allow the battery to cool down. If the battery gets too hot, it will not charge properly.

If available, try another battery and AC adapter.

If the notebook has a short operating time

If you are running an application that has an automatic save feature (such as Microsoft Word), disable this feature or increase the specified save time to reduce hard disk access.

If the operating time has gradually become shorter and the battery is more than a year or two old, you may need to replace the battery.

Heavy modem use or PC card use can affect battery operating time.

Use the BIOS configuration utility to make sure I/O Performance is set to Max Battery Life—see “Using the BIOS Configuration Utility” on page 26.

The battery gauge may need to be calibrated. Restart the notebook, press F6 when the HP logo appears, and follow the instructions that appear onscreen. This process calibrates the battery, and requires four to five hours to complete. You cannot use the notebook during this time.

If the Time Remaining for the battery is not correct

The Time Remaining is an estimate based on the rate at which the notebook is using power at that instant. So, if you check the Time Remaining while the notebook is using a good deal of power (such as when reading from a CD or DVD), the value will likely show less time remaining than you really have, since you will probably later switch to tasks that require less power.

Printing Problems

Hint

You can solve most printing problems using the printing troubleshooter in Windows Help and Support.

If a printer doesn’t print

Check for printer errors.

Make sure the printer is on and has paper in it.

Make sure you are using the correct printer cable or cable adapter, and that the cable is securely connected at both ends.

If the left edge of printed output is missing

Certain applications may not work properly with 600-dpi printers. If you’re using such a printer, try selecting a compatible printer driver for a 300-dpi printer. For example, if you were using a 600-dpi HP LaserJet printer, you might try using the HP LaserJet IIIsi driver (300 dpi).
