Suggested Troubleshooting Steps
If the system is not able to identify any network after connecting the network cable to the
network port, try the following troubleshooting steps:
1. Make sure that the network driver has been installed and is working properly.
2. Check System Setup to make sure that the NIC is enabled.
3. Try reseating the cable.
4. Try a known good cable, if one is available.
5. If a known good system is available, check if that system is connecting to the network.
6. Run the ePSA diagnostics on the network port.
NOTE: If the integrated network hardware solution is defective or nonfunctional, replace the
system board.
No additional drivers or updates are needed for VGA functionality. When troubleshooting an
external monitor, keep these tips in mind:
● Check both ends of the cable for a snug connection into the laptop and into the external
monitor.
● Adjust the contrast and brightness controls on the external monitor.
● Make sure that the notebook is not set to internal display only.
● Swap with a known good cable.
● Try with a known good external monitor. Check the external device's documentation for any
additional steps required for functionality.
NOTE: If the VGA hardware port is defective or nonfunctional, replace the system board.
