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 don't understand a feature, contextsensitive 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 LPT 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 Troubleshooting Procedures (Section 5) for additional information regarding the Diagnostics Program.

3.7 Using Zoomed Video Features
Your computer supports Zoomed Video (ZV) PC Cards through the PC Card slots. ZV PC Cards connect to the internal ZV port, allowing advanced multimedia capabilities such as video conferencing and on-screen television at full, smooth motion. The Zoomed Video port adds a dedicated video bus that provides a direct link between a PC Card and the VGA accelerator or audio DAC. This "detour" lets video and audio data bypass the PCI bus, reducing bandwidth impositions and improving system performance for more fluid audio and video.
3.7.1 MPEG PC Card
The optional MPEG PC Card uses the Zoomed Video port built into the computer to display MPEG video and audio on the computer. The MPEG card features MPEG-1 video playback with 16.7 million colors, MPEG-1 audio layers I and II, is MPC3 compliant and Windows 95 Plug and Play. With this option you can run full-motion video, combined with digital audio, graphics, text and data, enabling you to create far more effective presentations or play the most advanced video games.
3.8 Battery Saving Tips
There are a number of actions you can take to reduce the rate at which your computer depletes the battery. By taking some or all of these actions, you can substantially increase the time you can operate on battery power before recharging the battery:
Reducing screen brightness -- Although the screen controller uses new
technology to increase brightness without increasing energy consumption, the screen is still the largest single consumer of the battery charge. Reducing the brightness to the lowest acceptable level increases battery life. To reduce the brightness, press Fn+.
Caching the hard disk drive --- By caching the hard disk drive, you can reduce
the length of time the hard disk drive is rotating and using energy. Both Windows 95 and Windows for Workgroups use a disk-caching program by default. As long as you have not disabled these programs, you can take advantage of the battery savings.
3.8.1 Lowering Inactivity Timeouts
Inactivity timeouts turn off devices in the computer when you are not using them. Lowering the inactivity timeouts shortens the period of time the computer waits before turning off the device.
Operating Instructions 3-9
3.8.2 Suspending Operation While Idle
Although the computer goes into Suspend mode automatically after a defined period of inactivity, you can reduce energy consumption even further by pressing either Fn+F3 (Suspend) or Fn+F4 (Standby) as soon as you no longer need the computer to be active.
Pressing Fn+F4 (Standby) turns off the screen. Pressing Fn+F3 (Suspend) turns off the screen, stops the hard disk drive, and
reduces energy usage to the lowest level possible without turning off the computer.
Pressing the Shift key resumes activity after the notebook has been in either
the Suspend or Standby modes.
3.8.3 Responding to a Low Battery Condition
When you are operating the computer on battery power and the charge remaining is down to between 10% and 20%, the battery-low indicator blinks and an audible alarm sounds. When this happens you should take the following actions to conserve battery power and reduce the possibility of data loss.
Saving files -- Save all open files frequently while the computer is in a low-battery condition. Turning off the alarm -- Turn off the audible alarm by pressing Fn+End (Mute). Reducing screen brightness -- Reduce screen brightness by pressing Fn+. Connecting the AC adapter -- If you have access to AC power, connect the computer to the AC adapter. You can do this without turning off the computer. Suspending operations -- Press Fn+F3 or Fn+F4 to put the computer into Suspend or Standby mode whenever you are not actively using the computer. Press the Shift key to bring the computer out of Suspend or Standby mode.
3-10 Operating Instructions
3.8.4 Replacing the battery
If you have a spare, charged battery, you can do one of the following.
Insert a secondary battery into the MPB option (if installed). If you already have a battery in a docked MPB, you can replace the primary
battery without turning off the computer.
If you cannot insert the spare battery, suspend operations to disk by pressing
Fn+F2 and replace the battery. When you turn on the computer, the computer returns to the saved state.
3.8.5 Saving to Disk
When the battery power becomes critically low (less than 5% charge remaining), the computer saves the current state of the computer to disk and turns off. When you turn the computer on again, the computer restores the state that was saved to disk.
