Preface
Before using this information and the product it supports, please read the following general information. 1. This Service Guide provides you with all technical information relating to the BASIC CONFIGURATION decided for Acer's "global" product offering. To better fit local market requirements and enhance product competitiveness, your regional office MAY have decided to extend the functionality of a machine (e.g. add-on card, modem, or extra memory capability). These LOCALIZED FEATURES will NOT be covered in this generic service guide. In such cases, please contact your regional offices or the responsible personnel/channel to provide you with further technical details. Please note WHEN ORDERING FRU PARTS, that you should check the most up-to-date information available on your regional web or channel. If, for whatever reason, a part number change is made, it will not be noted in the printed Service Guide. For ACER-AUTHORIZED SERVICE PROVIDERS, your Acer office may have a DIFFERENT part number code to those given in the FRU list of this printed Service Guide. You MUST use the list provided by your regional Acer office to order FRU parts for repair and service of customer machines.

Function Execute

Select Drag
Click once. Click and hold, then use finger on the Touch Pad to drag the cursor.

Access context menu

NOTE: When using the Touch Pad, keep it - and your fingers - dry and clean. The Touch Pad is sensitive to finger movement; hence, the lighter the touch, the better the response. Tapping too hard will not increase the Touch Pads responsiveness.

Using the Keyboard

The keyboard has full-sized keys and an embedded numeric keypad, separate cursor, lock, Windows, function and special keys.
Lock Keys and embedded numeric keypad
The keyboard has three lock keys which you can toggle on and off.
Lock key Caps Lock Num Lock <Fn> + <F11>
Description When Caps Lock is on, all alphabetic characters typed are in uppercase. When Num Lock is on, the embedded keypad is in numeric mode. The keys function as a calculator (complete with the arithmetic operators +, -, *, and /). Use this mode when you need to do a lot of numeric data entry. A better solution would be to connect an external keypad. When Scroll Lock is on, the screen moves one line up or down when you press the up or down arrow keys respectively. Scroll Lock does not work with some applications.
Scroll Lock <Fn> + <F12>
The embedded numeric keypad functions like a desktop numeric keypad. It is indicated by small characters located on the upper right corner of the keycaps. To simplify the keyboard legend, cursor-control key symbols are not printed on the keys.
Desired access Number keys on embedded keypad Cursor-control keys on embedded keypad Main keyboard keys
Num Lock on Type numbers in a normal manner. Hold <Shift> while using cursorcontrol keys. Hold <Fn> while typing letters on embedded keypad.

Num Lock off

Hold <Fn> while using cursorcontrol keys. Type the letters in a normal manner.

Windows Keys

The keyboard has two keys that perform Windows-specific functions. Key Description
Windows key Pressed alone, this key has the same effect as clicking on the Windows Start button; it launches the Start menu. It can also be used with other keys to provide a variety of functions:

Power On Issue

If the system doesnt power on, perform the following actions one at a time to correct the problem. Do not replace a non-defective FRUs:
Computer Shutsdown Intermittently

Check the power cable is properly connected to the computer and the electrical outlet. Remove any extension cables between the computer and the outlet. Remove any surge protectors between the computer and the electrical outlet. Plug the computer directly into a known good electrical outlet. Disconnect the power and open the casing to check the Thermal Unit (see Thermal Unit Failure on page 142) and fan airways are free of obstructions. Disable the power management settings in the BIOS to ensure they are not the cause of the problem (see Power on page 35). Remove all external and non-essential hardware connected to the computer that are not necessary to boot the computer to the failure point. Remove any recently installed software. If the Issue is still not resolved, see Online Support Information on page 197.

No Display Issue

If the Display doesnt work, perform the following actions one at a time to correct the problem. Do not replace a non-defective FRUs:

No POST or Video

If the POST or video doesnt display, perform the following actions one at a time to correct the problem. 1. Make sure that the internal display is selected. On this notebook model, switching between the internal display and the external display is done by pressing Fn+F5. Reference Product pages for specific model procedures. Make sure the computer has power by checking at least one of the following occurs:
Fans start up Status LEDs light up
If there is no power, see Power On Issue on page 128. 3. 4. Drain any stored power by removing the power cable and battery and holding down the power button for 10 seconds. Reconnect the power and reboot the computer. Connect an external monitor to the computer and switch between the internal display and the external display is by pressing Fn+F5 (on this model). If the POST or video appears on the external display, see LCD Failure on page 131. 5. Disconnect power and all external devices including port replicators or docking stations. Remove any memory cards and CD/DVD discs. Restart the computer. If the computer boots correctly, add the devices one by one until the failure point is discovered. 6. 7. 8. Reseat the memory modules. Remove the drives (see Disassembly Process on page 44). If the Issue is still not resolved, see Online Support Information on page 197.
