Using the Keyboard

The keyboard has full-sized keys and an embedded keypad, separate cursor keys, two Windows keys and twelve function keys.
Lock Keys and embedded numeric keypad
The keyboard has three lock keys which you can toggle on and off. Aspire 3620:
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 Num Lock On Type numbers in a normal manner. Hold <Shift> while using cursor-control keys. Hold <Fn> while using cursor-control keys. Num Lock Off
Desired Access Main keyboard keys
Num Lock On Hold <Fn> while typing letters on embedded keypad.
Num Lock Off Type the letters in a normal manner.

Windows Keys

The keyboard has two keys that perform Windows-specific functions.
Key Windows key Icon Description 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 function: + <Tab> Activates next taskbar button. + <E> Opens the My Computer window + <F1> Opens Help and Support. + <F> Opens the Find: All Files dialog box. + <R> Opens the Run dialog box. + M Minimizes all windows. <Shift>+ action. Applicati on key + <M> Undoes the minimize all windows

NOTE: If you cannot find a symptom or an error in this list and the problem remains, see Undetermined Problems on page 82.

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. 2. 3. Run the advanced diagnostic test for the system board in loop mode at least 10 times. If no error is detected, do not replace any FRU. 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 System Check on page 67.): 1. 2. 3. Power-off the computer. Visually check them for damage. If any problems are found, replace the FRU. 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. 5. 6. 7. Power-on the computer. Determine if the problem has changed. If the problem does not recur, reconnect the removed devices one at a time until you find the failing FRU. If the problem remains, replace the following FRU one at a time. Do not replace a non-defective FRU: System board LCD assembly
