Troubleshooting and Maintenance

Troubleshooting Your Computer

•Make sure you’re using only the HP F4600, F4814, or 0950-4334 AC adapter included with your computer (or other approved adapter that meets the power requirements of the computer). Do not use a 60-watt, 3.16-amp adapter, such as HP F1454 or F1781.

•Move the computer 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.

Startup Problems

If the computer doesn’t respond when you turn it on

•Connect the AC adapter.

•Press the power button to try turning on the unit.

•Reset the computer by inserting the tip of a ballpoint pen into the reset button on the bottom of the computer. Then press the power button to turn it on.

•If the computer still doesn’t respond, remove the battery and AC adapter, remove any PC cards, and undock the computer if docked. Then plug in the AC adapter again, and reset the computer using the reset button.

If the computer won’t boot from battery power

•Make sure the battery is properly inserted and fully charged. Check the battery’s charge by removing it and pressing the pad on the side of the battery. The lights show the charge level.

•If available, try another battery.
