Troubleshooting and Maintenance

Troubleshooting Your Notebook

If the USB port is not working

Contact the vendor of the peripheral device for the latest USB drivers.

Check the port settings in Control Panel. Open the hardware Device Manager, then select Universal Serial Bus Controller.

Startup problems

If the notebook does not respond when you turn it on

Connect the AC adapter.

Reset the notebook by inserting the tip of a paper clip into the reset button on the bottom of the notebook. Then press the power button to turn it on.

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

If the notebook won’t boot from battery power

Make sure the battery is properly inserted and fully charged. Check the battery 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.

If the notebook will not boot from the diskette drive

Make sure the diskette drive is selected as the boot device. See the “Basic Operation” chapter in this guide for directions.

If you’re using a USB diskette drive, use the BIOS Setup utility to make sure Legacy USB Support is enabled. If your notebook also has a built-in diskette drive, use the BIOS Setup utility Boot menu to make sure the USB diskette drive is the first device under Removable Drive.

If the notebook stops responding after booting

Check whether you are connected to a TCP/IP network with no DHCP server. This can cause a long delay at startup because DHCP is enabled. Contact your network administrator to determine the proper TCP/IP configuration.
