Acer Extensa 660 Maintenance Manual

							                                                                                                            General Description  1-13  
Table 1-6  shows how to interpret the battery indicators.
1.4.2 External Battery Charger Option
An optional external battery charger is available that charges a battery outside of the 
computer (all three types of batteries used by the Extensa 660 Series). To order an 
optional battery charger (or any of the Extensa options), contact your computer dealer 
or call Texas Instruments at 
1-800-TI-TEXAS.
1.5 Standard Test Features
The Extensa 660 Series Notebook Computers use modular design and built-in test 
features to reduce the mean time to repair. A power on self test program automatically 
verifies the operational state of the primary circuits and a powerful suite of diagnostic 
tests (known as PC-Doctor) are available to further test selected parts of the system.
1.5.1 Power On Self Test
The Extensa line of notebook computers contain a BIOS-resident, Power On Self Test 
(POST) that automatically performs a test of memory and all major circuits each time 
the computer is powered up. In the event of a failure, the computer displays a descriptive 
error message and issues a series of coded beeps (in case the display subsystem is not 
functioning). If self test completes normally, the computer displays the amount of 
memory tested, loads the Operating System and Windows environment.
1.5.2 PC-Doctor Diagnostics Program
The Extensa 660 Series Notebooks are shipped with PC-Doctor for Windows, a powerful 
diagnostics tool that can help you scan a system for viruses, determine the hardware 
configuration of a local or remote system, benchmark its performance, analyze the 
performance of all subsystems, and perform a suite of interactive and non-interactive 
tests on attached devices (such as printers, VGA monitors, SCSI
® devices, CD-ROM 
drives). The test results are stored in a log which can be printed out (by pressing F2) 
or saved in a disk file (by pressing F3).
Features of the diagnostic program are accessed through a series of pull-down menus 
and basic keyboard keys (cursor keys to move highlighted pointer, Enter key to select 
a highlighted feature, Esc key to cancel a function and move back one level. Table 1-6  Interpreting the Battery Charge Indicators

							1-14   General Description
PC-Doctor is typically user -friendly but if you dont understand a feature, context-
sensitive help information is available at any time by pressing the F1 function key; 
pressing the F1 function key twice accesses the online Technical Reference Manual for 
PC-Doctor. 
A powerful set of utilities within PC-Doctor (that can be run locally or remotely) simplify 
the task of determining system configuration data, allocating and using system memory, 
IRQ and DMA use, what device drivers are installed, what COM and LP T ports are 
assigned and what ports are available, identifying partitioning data for fixed disk 
drive(s), determining the VGA setup information, reading the software interrupts/
interrupt vectors, etc.
Note: Refer to T roubleshooting Procedures (Section 5) for additional information 
regarding the Diagnostics Program.

							2-2   Installation
2.3  Installing Internal Notebook Options
If you have no internal options to install at this time, skip to Paragraph 2.4. Otherwise, 
continue with Paragraph 2.3.1.
2.3.1 Installing Main Memory Expansion (Optional)
Main memory on the 660 Series Notebooks can be expanded using  an EDO Small 
Outline Dual Inline Memory Module (EDO soDIMM). These modules are available in 
16 MB,  32 MB, and 64 MB sizes and install in the expansion memory slot on the System 
Board accessed through the Memory Expansion Door on the bottom of the notebook. 
The installation process consists of the following steps:
Caution: The EDO soDIMM module option contains components that are 
sensitive to static electricity. When handling the module and the internal 
parts of the computer, protect against static electricity by using wrist or 
ankle grounding straps and grounded working mats. When moving or 
storing items, use the anti-static bags supplied with the items.
1.Ensure that the notebook is powered off and the AC adapter disconnected 
from the AC outlet. Also, ensure that all batteries are out of the unit.
2.Disconnect any peripheral device interface cables from the external interface 
connectors and remove any installed PCMCIA options.
3.Turn the notebook over and locate the Expansion Memory Access Cover on 
the bottom of the notebook.
4.Remove the screw holding the Expansion Memory Access Cover and remove 
the cover.
5.Remove the EDO soDIMM module from its shipping container.
6.Refer to Figure 2-1. To install an soDIMM module, first align the connector 
edge of the memory module with the key in the connector. Insert the edge of 
the memory module board into the connector using a rocking motion to fully 
insert the module. Push downward on each side of the memory module until 
it snaps in place.
7.Reinstall the Expansion Memory Access Cover using the screw removed in 
Step 4.
8.Replace the batteries and AC adapter.
9.Power up the notebook. If all of the installed memory is not recognized, try 
reseating the soDIMM module and rebooting.

Figure 2-1  Memory Expansion Removal/Replacement
Note: After installing expansion memory in your notebook, you must run the 
PHDISK utility in order for the Save-To-Disk or 0V Suspend functions to operate 
correctly.
2.3.2 Setting up the Software
Note:  If you are using an operating system other than Windows 95, Windows for 
Workgroups, or DOS, you may need to re-partition your hard disk drive to allow 
for the additional memory. Check with your system administrator.

In Windows 95
Follow these steps if your computer is running Windows 95.
1.From the Taskbar, select Start then Shut Down.
2.Select the Restart the Computer in MS-DOS mode.
3.Click on Ye s.
4.Type PHDISK /C /F at the DOS prompt and press Enter.
5.The DOS screen appears and shows the save file name and size. Press any 
key to reset the system. The computer will reboot.
In Windows for Workgroups
Follow these steps if your computer is running MS-DOS and Windows for Workgroups.
1.Close all applications and exit Windows for Workgroups to MS-DOS.
2.At the command prompt (typically C:\) type PHDISK /C /F and press Enter. 
This will create a file which can be used to save the contents of your memory 
system when you perform a 0V Suspend operation.
2.3.3 Installing Advanced PCI Option Card
To install an Advanced PCI Card option, use the following procedure:
Caution: The Advanced PCI card option contains components that are 
sensitive to static electricity. When handling the card and the internal 
parts of the computer, protect against static electricity by using wrist or 
ankle grounding straps and grounded working mats. When moving or 
storing items, use the anti-static bags supplied with the items.
1.Ensure that the notebook is powered off and the AC adapter disconnected 
from the AC outlet. Also, ensure that the battery is out of the unit.
2.Disconnect any peripheral device interface cables from the external interface 
connectors and remove any installed PCMCIA options.
3.Turn the notebook over and locate the Advanced PCI Access Cover on the 
bottom of the notebook (refer to Figure 2-2).
4.Remove the screw holding the Advanced PCI Access Cover and remove the 
cover.
5.Review the installation instructions supplied with the Advanced PCI option 
card.
6.   Hold the card at the end opposite the connector pins with the label side up. 
Insert the card firmly into the Advanced PCI connector on the Main Board.
