Aside from the email checking function, there is a mail button that is used to launch the email application. It is located above the keyboard right below the LCD.
Touchpad The built-in touchpad is a pointing device that senses movement on its surface. This means the cursor responds as you move your finger on the surface of the touchpad. The central location on the palmrest provides optimal comfort and support. NOTE: If you are using an external USB mouse, you can press Fn-F7 to disable the touchpad. Touchpad Basics The following teaches you how to use the touchpad: T Move your finger across the touchpad to move the cursor.
Function Scroll Left Button Right Button Scroll Button Tap Click and hold the button in the desired direction (up/ down/left/right) NOTE: Keep your fingers dry and clean when using the touchpad. Also keep the touchpad dry and clean. The touchpad is sensitive to finger movements. Hence, the lighter the touch, the better the response. Tapping too hard will not increase the touchpad’s responsiveness.

Chapter 4 Troubleshooting Use the following procedure as a guide for computer problems. NOTE: The diagnostic tests are intended to test this model. Non-Acer products, prototype cards, or modified options can give false errors and invalid system responses. 1. Duplicate symptom and obtain the failing symptoms in as much detail as possible. 2. Distinguish symptom. Verify the symptoms by attempting to re-create the failure by running the diagnostic test or by repeating the same operation. 3.
System Check Procedures External Diskette Drive Check Do the following to isolate the problem to a controller, driver, or diskette. A write-enabled, diagnostic diskette is required. NOTE: Make sure that the diskette does not have more than one label attached to it. Multiple labels can cause damage to the drive or cause the drive to fail. Do the following to select the test device. 1. Boot from the diagnostics diskette and start the diagnostics program. 2.
Memory check Memory errors might stop system operations, show error messages on the screen, or hang the system. 1. Boot from the diagnostics diskette and start the doagmpstotics program (please refer to main board. 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 fully installed into the connector. A loose connection can cause an error.
Check the Battery Pack To check the battery pack, do the following: From Software: 1. Check out the Power Management in control Panel 2. In Power Meter, confirm that if the parameters shown in the screen for Current Power Source and Total Battery Power Remaining are correct. 3. Repeat the steps 1 and 2, for both battery and adapter. 4. This helps you identify first the problem is on recharging or discharging. From Hardware: 1. Power off the computer. 2.
Power-On Self-Test (POST) Error Message The POST error message index lists the error message and their possible causes. The most likely cause is listed first. NOTE: Perform the FRU replacement or actions in the sequence shown in FRU/Action column, if the FRU replacement does not solve the problem, put the original part back in the computer. Do not replace a non-defective FRU. This index can also help you determine the next possible FRU to be replaced when servicing a computer.

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: 80 1. Run the 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.
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 System Check” on page 67): 1.
