Chapter 4 41 This chapter provides instructions on how to troubleshoot system hardw are problems. Hardware Diagnostic Procedure The system’s diagnostic function monitors system activity and performs IMPORT AN T : T he diagnostic tests described in this chapter ar e only intende d to test Acer products.
42 Chapter 4 System Check Procedures Power system check If the system will power on, skip this sect ion. Refer to System External In spection. If the system will not power on, check if the power cabl e is properly conne cted to the system and AC source.
Chapter 4 43 System Diagnosis Hardware diagnostic program The purpose of the hardware dia gnostic progra m is to check hardware probl ems. It executes simple tests of each hardware component to make sure the hardware is not the source of the problem.
44 Chapter 4 6. After the diagnostic routine is completed, the HDD stat us indicator lights purple indicating the system has passed all diagnostic tests. 7. A copy of the test result will be saved as a l og file (i.e., 66380AC3.LOG) and stored in the Results folder .
Chapter 4 45 POST Code Checkpoints The Power-On Self T est (POST) is a BIOS procedure that boots the system, initializes and diagnoses the system components, and controls the operation of the pow e r-on password option.
46 Chapter 4 Bootblock recovery code checkpoints The Bootblock recovery code gets control when the BIOS determines that a BIOS recovery needs to occur because the user has forced the upda te or the BIOS checksum is corrupt .
Chapter 4 47 POST code checkpoints The POST code checkpoints are the largest set of ch eckpoints during the BIOS pre-boot process. The following table describes the type of checkpoints th at may occur during the PO ST po rtion of the BIOS: Checkpoint Des cription 03 Disable NMI, Parity , video for EGA, and DMA controllers.
48 Chapter 4 Device Initialization Manager code checkpoints The Device Initialization Manager (DIM) module gets cont rol at various times during BIOS POST to initialize different BUSes.
Chapter 4 49 While control is in the different f unctions, additional checkpoints are output to port 80h as a word value to identify the routines under execution. The low byte value indi cates the main POST Cod e Checkpoint. The high byte is di vided into two nibbles and contains two fi elds.
50 Chapter 4 System Status Error Codes NOTE: Perform the FRU replacement or acti ons in the s equence shown in FRU/Action column, if the FRU replacement does not solve the probl em, put the original part back in the computer . Do not replace a non-defective F RU.
Chapter 4 51 BIOS Recovery Perform the BIOS recovery if the BIOS flash ROM has become corrupted. The foll owing sections provide instructions on how to recover BIOS settings. To create a BIOS Recovery disk: 1. Prepare a USB storage device. 2. Connect the USB storage device to a USB port on your computer .
52 Chapter 4 Clearing CMOS T o clear the BIOS configuratio n you need to shor t the JP3 Clear CMOS jumper on the mainbo ard. 1. T urn off the computer and all attached devices. 2. Remove the system cover . See “R emoving the System Cover” on page 25.
Chapter 4 53 Undetermined Problems The diagnostic proble ms does not identify wh ich adapter or device failed, wh ich installed devices are incorrect, whether a short circuit is suspected, or whether the system is inoperative. NOTE: V erify that all attached devices a re supported by the computer.
