Parallel Port Tests

0701h	For the external loopback test, make sure the
	loopback connector is installed and constructed
	properly. For the external or internal loopback
	test, replace the motherboard.
0702h	Replace the motherboard.
0703h	Run BIOS Setup and disable ECP for the
	parallel port, then rerun the test. Replace the
	motherboard.
0704h -	Replace the motherboard.
0706h
0707h	Connect the loopback connector.
0708h	Replace the motherboard.
Audio Tests
0801h -	If this error also occurs for an external
0812h	headphone, replace the motherboard.
	Otherwise, check the speaker connections,
	replace the speakers. If it occurs only for an
	external headphone, replace the audio jack
	PCA.
9003h -	(See Microphone Tests near end of table.)
9004h
Video Tests
0900h -	Replace the VGA PCA.
0901h
0903h -	Replace the LVDS PCA. Replace the VGA
0906h	PCA.
0907h -	Replace the VGA PCA.
0908h
0909h -	Replace the LVDS PCA. Replace the VGA
090Ah	PCA.
090Ch -	Replace the VGA PCA.
090Fh
8000h	(See LCD Test near end of table.)
CD-ROM Tests
0A00h	Insert a CD in the drive.
0A01h	Rerun the test. Replace the CD-ROM drive.
0A02h	No repair. (Automatic close not supported.)
0A03h	Insert a different CD in the drive. Check the
	connectors on the CD-ROM drive and
	motherboard. Replace the CD-ROM drive.
0A04h	Insert a different CD in the drive. Check the
	connectors on the CD-ROM drive and
	motherboard. Replace the CD-ROM drive.
0A05h	Insert a computer CD in the drive.
0A06h	Insert an audio CD in the drive.
USB Tests
1301h	Reprogram the BIOS IC. Replace the BIOS IC.
	Replace the motherboard.

1302h -	Replace the motherboard.
1306h
9006h	(See USB Port Test near end of table.)
LCD Test
8000h	If the test fails with an external monitor (must
	support VESA mode 105h), replace the VGA
	PCA, replace the motherboard. Otherwise:
	- If the shaded-band test fails, check the LCD
	flex cable connection in the bottom case,
	replace the LVDS PCA, replace the LCD flex
	cable, replace the VGA PCA, replace the
	motherboard.
	- If only a solid-color test fails, see chapter 5 for
	cosmetic guidelines, replace the LCD module.

9003h	If the error occurs for built-in and external
	microphones, replace the motherboard. If it
	occurs for only the built-in microphone, check
	the LCD flex cable connection, replace the
	inverter PCA. If it occurs only for an external
	microphone, replace the audio jack PCA.
9004h	Replace the audio jack PCA. Replace the
	motherboard.
Suspend/Resume Test
9005h	Run BIOS Setup and restore default settings.
	Reprogram the BIOS IC. Replace the BIOS IC.
	Replace the motherboard.
USB Port Test
9006h	Make sure a USB device is connected to the
	port you are testing. Select the correct speed
	for the device. Replace the motherboard (or
	dock component, if applicable).
IR Tests (FIR enabled, undocked)
9002h,	Rerun the test. Replace the motherboard.
9007h -
9008h
9009h	Do not run this test in Windows. For the one-
	unit test, replace the motherboard. For the two-
	unit test, make sure the IR ports on the
	reflector and test computers are lined up,
	replace the IR PCA, replace the motherboard.
900Ah	Rerun the test. For the two-unit test, make sure
	the IR ports on the reflector and test computers
	are lined up. Replace the IR PCA, replace the
	motherboard.
900Ch	Rerun the test. Make sure the IR ports on the
	reflector and test computers are lined up.
	Restart the reflector unit. Replace the IR PCA,
	replace the motherboard.
