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.

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.

Microphone/Line-In Tests

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.
