A second identical battery can be installed in the optional Mobile Connectivity Base as shown in Figure 1-7. 1.4 Standard Test Features The Extensa 900 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. 1.4.1 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 PS/2 Keyboard Port PS/2 Mouse PortParallel PortSerial PortVGA PortAdvanced PCILine OutLine In Mic In
General Description 1-13 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. 1.4.2 PC-Doctor Diagnostics Program The Extensa 900 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. 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 900 Series Notebooks can be expanded using an EDO Small Outline Dual Inline Memory Module (EDO soDIMM). These modules are available in 8 MB, 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.
