Chapter 475 Please use the following procedures as a guide for computer problems. Note: The diagnostic tests are intended to test only Acer products. Non-Acer products, prototype cards, or modified options may occur errors or invalid responses. 1. Obtain the detailed fail symptoms as many as possible. 2. Verify the symptoms by attempting to recreate, running the diagnostic tests or repeating the same operation. Troubleshooting Chapter 4
76Chapter 4 System Check Procedures External Diskette Drive Check Do the following procedures to isolate the possible effects from a controller, driver, or diskette. A writable, diagnostic diskette is required. Note: Make sure that the diskette does not have more than one label attached. Multiple labels may cause damage to the drive or make the drive fail. 1. Boot from the diagnostic diskette and start the diagnostic programs. 2. See if FDD test is passed as the programs run the FDD test. 3. Follow the instructions in the message window. If errors occur with the internal diskette driver, reconnect the diskette connector on the system board. If the errors still remain: 1. Reconnect the external diskette drive. 2. Replace the external diskette driver. 3. Replace the main board. External CD-ROM Drive Check Do the following procedures to isolate the possible effects from a controller, driver, or CD-ROM. Note: Make sure that the CD-ROM does not have any label attached. The label may cause damage to the drive or make the drive fail. 1. Boot from the diagnostic diskette and start the diagnostic programs. 2. See if CD-ROM test is passed when the programs run the CD-ROM test. 3. Follow the instructions in the message window. If errors occur, reconnect the connector on the system board. If the errors still remain: 1. Reconnect the external CD-ROM drive. 2. Replace the external CD-ROM drive. 3. Replace the main board. Keyboard or Auxiliary Input Device Check Remove the external keyboard if the internal keyboard is under test. If the internal keyboard does not work or an unexpected error appears, make sure that the flexible cable extending from the internal keyboard is correctly connected on the system board. If the keyboard is correctly connected, run the Keyboard test. If errors occur, do the following procedures in sequence to correct the problems. Do not replace a non-defective FRU. 1. Reconnect the keyboard cable. 2. Replace the keyboard. 3. Replace the main board. The following auxiliary input devices are supported by this computer. •Numeric keypad •External keyboard If any of these devices do not function, reconnect the cable and repeat the anterior procedures. Memory Check Follow the procedures below to correct the memory errors. 1. Boot from the diagnostic diskette and start the diagnostic programs.
Chapter 477 2. Go to the diagnostic memory in the test items. 3. Press F2 in the test items. 4. Follow the instructions in the message window. Note: Make sure that the DIMM is correctly inserted into the connector. A wrong connection will cause errors. Power System Check To verify the symptoms, power on the computer by using the following power sources separately. 1. Remove the battery pack. 2. Connect the power adaptor and check the power supply. 3. Disconnect the power adaptor and install the battery pack, then check the power supply. If you think there is a power supply problem, please go to Check the Power Adaptor and Check the Battery Pack in this chapter. Check the Power Adaptor Unplug the power adaptor cable from the computer and measure the output voltage at the plug of the power adaptor cable. See the illustration and follow the procedures below. 1. If the voltage is not correct, replace the power adaptor. 2. If the voltage is within the range: (1)Replace the system board. (2)If the problem is still not resolved, see Undetermined Problems. (3)If the voltage is not correct, go to the next step. Note: An audible noise from the power adaptor does not always indicate a defect. 3. If the power-on indicator does not light up, check the power cord of the power adaptor for continuity and correct installation. 4. If the operational charge does not work, see Check the Battery Pack. Check the Battery Pack Follow the procedures below to check the battery pack. From software, this helps to identify the problem is on recharging or discharging. 1. Check the Power Management in Control Panel. 2. Then confirm that the parameters shown in the screen for Current Power Source and Total Battery Power Remaining are correct. 3. Repeat the step 1 and step 2 for both battery and adaptor. From hardware, this helps to identify whether you should replace the battery pack or not. 1. Power off the system. 2. Remove the battery pack and measure the voltage between terminals one (+) and seven (-). There are seven terminals totally. See the illustration below. 3. If the voltage is still less than 7.5V after recharging, replace the battery. If the battery status indicator does not light up, remove the battery pack. After the battery pack returns to room temperature, reinstall it to the system. pin 1: +19V to +20.5V pin 2: 0V, ground
78Chapter 4 If the charge indicator does not light up, replace the battery pack. If the charge indicator still does not light up, replace the AC / DC charger board. Touchpad Check If the touchpad does not work, follow the procedures one at a time to correct the problem. Do not replace a non- defective FRU. 1. Reconnect the touchpad cables. 2. Replace the touchpad. 3. Replace the system board. After you use the touchpad, the pointer drifts on the screen for a short time. This self-acting pointer movement will occur when a slight, steady pressure is applied to the touchpad pointer. This symptom is not a hardware problem.
Chapter 479 Power-On Self-Test (POST) Error Message The POST error message index lists the error message and their possible causes. Note: Perform the FRU replacement or actions in the sequence shown in Error Message List, if the FRU replacement does not solve the problem, put the original part back in the computer. Do not replace a non- defective FRU. The error messages are listed in the coming pages to indicate the BIOS signals on the screen and the error symptoms classified by functions. If the symptom is not included on the list, please refer to Undetermined Problems. Note: Most of the error messages occur during POST. Some of them show information about a hardware device, for example, the size of memory installed. Others may indicate problems with a device, such as the way it has been configured. Note: If the system fails after you make changes in the BIOS Setup Utility menus, please reset the computer. Enter Setup and install Setup defaults to correct the errors.
