Chapter 4141 USB Failure (Rightside) If the rightside USB port fails, perform the following actions one at a time to correct the problem. Do not replace a non-defective FRUs: Modem Function Failure If the internal Modem fails, perform the following actions one at a time to correct the problem. Do not replace a non-defective FRUs:
142Chapter 4 Wireless Function Failure If the WLAN fails, perform the following actions one at a time to correct the problem. Do not replace a non- defective FRUs: EasyTouch Button Failure If the Acer EasyTouch buttons fail, perform the following actions one at a time to correct the problem. Do not replace a non-defective FRUs:
Chapter 4143 MediaTouch Button Failure If the Acer MediaTouch buttons fail, perform the following actions one at a time to correct the problem. Do not replace a non-defective FRUs: Fingerprint Reader Failure If the Fingerprint Reader fails, perform the following actions one at a time to correct the problem. Do not replace a non-defective FRUs:
144Chapter 4 Thermal Unit Failure If the Thermal Unit fails, perform the following actions one at a time to correct the problem. Do not replace a non-defective FRUs: HDTV Switch Failure If the HDTV Switch fails, perform the following actions one at a time to correct the problem. Do not replace a non-defective FRUs:
Chapter 4145 External Mouse Failure If an external Mouse fails, perform the following actions one at a time to correct the problem. 1.Try an alternative mouse. 2.If the mouse uses a wireless connection, insert new batteries and confirm there is a good connection. See the mouse user manual. 3.If the mouse uses a USB connection, try an alternate USB port. 4.Try an alternative program to verify mouse operation. Reinstall the program experiencing mouse failure. 5.Restart the computer. 6.Remove any recently added hardware and associated software. 7.Remove any recently added software and reboot. 8.Restore system and file settings from a known good date using System Restore. If the issue is not fixed, repeat the preceding steps and select an earlier time and date. 9.Run the Event Viewer to check the events log for errors. For more information see Windows Help and Support. 10.Roll back the mouse driver to the previous version if updated recently. 11 .Remove and reinstall the mouse driver. 12.Check the Device Manager to determine that: •The device is properly installed. There are no red Xs or yellow exclamation marks. •There are no device conflicts. •No hardware is listed under Other Devices. 13.If the Issue is still not resolved, see “Online Support Information” on page 195. Other Failures If the CRT Switch, Dock, LAN Port, external MIC or Speakers, PCI Express Card, 5-in-1 Card Reader or Volume Wheel fail, perform the following general steps to correct the problem. Do not replace a non-defective FRUs: 1.Check Drive whether is OK. 2.Check Test Fixture is ok. 3.Swap M/B to Try.
146Chapter 4 Intermittent Problems Intermittent system hang problems can be caused by a variety of reasons that have nothing to do with a hardware defect, such as: cosmic radiation, electrostatic discharge, or software errors. FRU replacement should be considered only when a recurring problem exists. When analyzing an intermittent problem, do the following: 1.Run the advanced diagnostic test for the system board in loop mode at least 10 times. 2.If no error is detected, do not replace any FRU. 3.If any error is detected, replace the FRU. Rerun the test to verify that there are no more errors. Undetermined Problems The diagnostic problems does not identify which adapter or device failed, which installed devices are incorrect, whether a short circuit is suspected, or whether the system is inoperative. Follow these procedures to isolate the failing FRU (do not isolate non-defective FRU). NOTE: Verify that all attached devices are supported by the computer. NOTE: Verify that the power supply being used at the time of the failure is operating correctly. (See “Power On Issue” on page 130.): 1.Power-off the computer. 2.Visually check them for damage. If any problems are found, replace the FRU. 3.Remove or disconnect all of the following devices: •Non-Acer devices •Printer, mouse, and other external devices •Battery pack •Hard disk drive •DIMM •CD-ROM/Diskette drive Module •PC Cards 4.Power-on the computer. 5.Determine if the problem has changed. 6.If the problem does not recur, reconnect the removed devices one at a time until you find the failing FRU. 7.If the problem remains, replace the following FRU one at a time. Do not replace a non-defective FRU: •System board •LCD assembly
