5.4 No internal display (LCD):

2. Connect an external CRT to the VGA port to check if video is present.
3. If video is present on external CRT, check the internal LCD cable connection.
4. Check your VGA setting using an external display to make sure LCD video is enabled.
5. If there is no video on external, check your system to make sure everything is seated properly.

5.6 Keyboard fails:
Note:
Typically, if the keyboard fails due to a faulty connection,
the TouchPad will also not work. If one or the other device works,
then it is a failed keyboard issue or a driver issue.
1. Make sure the keyboard plug is inserted completely into the front port.
2. Assure the internal keyboard connection is secure.
3. Make sure you do not have another keyboard connected to the motherboard I/O PS/2 port.
4. Test the a keyboard in the motherboard USB port.
5. Try another keyboard to isolate the problem to the keyboard or system.
5.7 Touchpad fails:
1. Make sure the keyboard plug is inserted completely into the port.
2. If you have an external PS/2 mouse hook up on the side I/O PS/2 port, the touch pad may not
function simultaneously.
3. If your operating system requires and does not load the mouse driver automatically, make sure
you have the proper mouse driver loaded.
4. Try another pointing device to isolate the problem to TouchPad versus system.
5.8 DVD-ROM fails:
1. Make sure the CD/DVD is readable.
2. If DVD-ROM fails to be recognized during POST, check internal cable fit.
5.9 Hard Drive fails:
1. Hard drives are the least reliable component in a system.
2. If Hard Drives fail to be recognized during POST, check internal cable fit.
3. Remove each drive canister and check the connectors for damage.
4. Remove and reinstall the canisters to assure they are properly seated and locked in place.
