Looking things over
Sometimes, the simplest things can cause trouble. To avoid unnecessary
service calls, be sure you check over the basics before you call for support.
In any complex system, there is potential for a forgotten connection, a
forgotten switch or a loose connector. Before powering up the system,
perform the following checks:
•
•
•
Is the power cord connected to the system unit and an AC outlet?
•
Does the voltage selection switch on the system power supply
reflect the proper voltage?
Is the AC outlet supplying power?
If you are using a power strip, is it turned on? Is the circuit breaker
set?
Verifying the configuration
If the system is not operating correctly, the BIOS may contain an invalid
configuration parameter. Enter the BIOS Setup program and check the
configuration settings.
Troubleshooting guidelines
As you troubleshoot the system, keep the following guidelines in mind:
•
•
Never remove the system covers while the system is powered up.
•
If a peripheral such as the keyboard, mouse, drive, or printer does
not appear to work, ensure that all connections are secure.
•
If the screen displays an error message, write it down,
word-for-word. You may be asked about it when calling Technical
Support.
•
•
Only qualified personnel should open the system for maintenance.
Do not attempt to open the monitor, it is extremely dangerous.
Even if the monitor power is disconnected, stored energy within the
monitor components can cause a painful or harmful shock.
If you are qualified to maintain the system yourself, make certain
you are properly grounded before opening the chassis.

Maintaining your hard drive
Hard drives need regular maintenance because running the system software
divides files, creates spaces between data, and otherwise decreases the hard
drive’s performance. Windows 95 and Windows NT provide maintenance
tools that help prevent possible hard drive problems. The most important
tools for hard drive maintenance are the programs ScanDisk (Windows 95
only), Check Disk (Windows NT only), and Disk Defragmenter (Windows
95 only).
Using ScanDisk
ScanDisk is a Windows 95 program that lets you check your hard disk for
damaged areas and then repairs them. We suggest you scan your hard drive
from at least once a week to once a month, depending on how often and
how much you use your computer.
To use ScanDisk
1. Click on the Start button. Then click on Programs, then Accessories, then
System Tools, and then ScanDisk.
The ScanDisk window opens.
2. In the ScanDisk window, click on the drive you want to scan.
3. If you only want to check your files and folders for errors, select the
Standard option button. If you want to do a more thorough scan for
errors, select the Thorough option.
Because the Thorough option takes more time than the Standard option,
we recommend you normally use the Standard option and do a Thorough
check at least once a month.
4. If you selected Standard and you want to change the settings ScanDisk
uses when it checks files and folders, click on the Advanced button,
select the options in the ScanDisk Advanced Options window, then
click on the OK button to close the window.
20
Gateway ALR 7200 User’s Guide
4076.book Page 21 Wednesday, January 6, 1999 3:48 PM
If you selected Thorough and want to change the settings ScanDisk uses
when it checks the disk’s surface, click on the Options button, select the
options from the Surface Scan Options window, then click on the OK
button to close the window.
5. If you want ScanDisk to automatically fix any errors it finds, select the
Automatically fix errors option in the ScanDisk window.
6. Click on the Start button in the ScanDisk window.
When the scan is complete, the ScanDisk Results window opens
giving you details of the scanning operation.
7. If you want to scan another drive, click on the Close button to return
to the ScanDisk window, select another drive, then go to Step 6.
8. When you are finished using ScanDisk, click on Close.
Using Check Disk
Windows NT provides the Check Disk utility to maintain the hard drive.
Check disk enables you to check the drive for errors, fix file system errors,
and attempt to recover bad sectors on the drive.
Use Check Disk from once a week to once a month, depending on how
often you use your computer. Also use Check Disk whenever you have any

6. Check Scan for and attempt recovery of bad sectors to scan the entire hard
drive.
7. Click Start. If the scan finds bad sectors, a screen message notifies
you.
Using Disk Defragmenter
The Disk Defragmenter program that comes with Windows 95 helps
maintain the integrity of your hard drive by rearranging files so that unused
space on your hard drive is not scattered around the drive, but is contained
in one contiguous area on the disk. You may notice, after running Disk
Defragmenter, that your programs run a little faster and more efficiently.
That is because the hard drive head can go directly to the data it needs
instead of skipping around to different places on the disk to find pieces of
data.
We suggest you run Disk Defragmenter at least once a week to once a
month, depending on how much you use your system.
To run Disk Defragmenter
1. Click on the Start button, then follow the popup menus through
Programs, then Accessories, and then System Tools. Then select Disk
Defragmenter.
A dialog box opens asking you to select a drive to defragment.
2. Select the drive from the pull-down menu, then click OK.
A dialog box opens showing the progress of the defragmentation.
When defragmentation is complete, a dialog box opens and asks you if
you want to quit the Disk Defragmenter program.
3. If you are finished defragmenting the drives in your system, click Yes.
If you have more drives to defragment, click No and return to Step 2.

Protecting against viruses
A virus is a program written with malicious intent for the sole purpose of
creating havoc in a computer system. It attaches itself to executable files or
boot sectors, so it can replicate and spread. Some viruses may only cause
your system to beep or display messages or images on the screen. Other
viruses are highly destructive and corrupt or erase the contents of your files
or diskettes. To be safe, never assume any virus is harmless.
Viruses spread through direct contact with executable programs or boot
sectors. Diskettes used in a contaminated system can get a virus and
transfer the virus when used in another system. A virus can also spread
through programs downloaded from bulletin boards or the Internet.
To protect your system against viruses
•
•
•
Obtain an anti-virus program and scan the system regularly.
Make backup copies of all files and write-protect the disks.
Obtain all software from reputable sources and always scan new
software for any viruses prior to installing files.
If you suspect your system has been infected, find and remove the viruses
immediately using an anti-virus program. Next, turn off your system and
leave it off for at least 15 seconds before turning it back on. This is the only
way to ensure the virus does not remain in your system RAM.

Cleaning your system
Your system and its components need to be cleaned occasionally. The
following sections contain information about caring for the various parts of
your system.
Cleaning the mouse
If the mouse pointer on the screen moves erratically when you move the
mouse, dirt is probably on the rollers inside the mouse.
To clean the mouse
1. Shut down the system.
2. Turn your mouse upside down and remove the mouse ball cover.
3. Cup your hand under the mouse, then turn your mouse right-side up.
The gray mouse-ball should drop into your hand. If it doesn’t, gently
shake the mouse until the ball drops out of the socket.
4. Once the mouse ball is free, use adhesive tape to pick up any dust or
lint on its surface and wipe away dirt or lint inside the mouse-ball
socket. You can also blow into the socket to remove dirt and lint. If
foreign matter is trapped inside the socket or on the rollers, use a
cotton swab dipped in isopropyl alcohol to loosen it. Allow surfaces to
dry completely after cleaning.
5. Return the mouse ball to the socket and replace the cover, then restart
the system.
Cleaning the keyboard
Occasionally you should clean the keyboard to free it of dust and lint
particles trapped under the keys. The easiest way to do this is to blow
trapped dirt from under the keys using an aerosol can of air with a narrow,
straw-like extension.

4076.book Page 25 Wednesday, January 6, 1999 3:48 PM
If you spill liquid on the keyboard, shut down the computer and disconnect
the keyboard. Turn the keyboard upside down to allow the liquid to drain
out overnight before trying to use it again. If it fails to work after draining,
contact Technical Support. Sticky liquids may cause residual problems even
after drying and may require the replacement of the keyboard.
Cleaning the monitor screen
Use a soft cloth and window cleaner to clean the monitor screen. Squirt a
little cleaner on the cloth (never directly on the screen), and wipe the screen
with the cloth.
Cleaning the computer and monitor cases
Always shut down the system and other peripherals before cleaning any
components.
Use a damp, lint-free cloth to clean the computer case, monitor case,
keyboard, speakers, and other parts of your system. Avoid abrasive or
solvent cleaners because they can damage the finish on your components.

Terms and definitions
This list of terms should help you get acquainted with terms used in your
computer’s documentation and in your system software.
Applications - Software installed on your system. Sometimes called
programs.
BIOS - Basic input/output system. The BIOS is software that is
independent of any operating system. It enables the computer to
communicate with the monitor, keyboard, and other peripheral devices
without using programs on the hard disk.
The BIOS on your computer is flash BIOS, which means that is has been
recorded on a memory chip that can be updated if needed.
Boot - To load the first software program (usually the operating system)
that starts your computer. To perform a cold (or hard) boot, you turn the
computer on when it is off. To perform a warm (or soft) boot, you reset the
computer when it is already turned on.
Boot disk - A disk containing operating system programs required to start
your computer. A boot disk can be a diskette, hard drive, or CD.
Byte - The basic unit of measure for computer memory. A character, such
as a letter of the alphabet, uses one byte of memory. Each byte is made up
of eight bits. Computer memory is often measured in kilobytes (1,024
bytes) or megabytes (1,048,576 bytes).
Cache memory - Cache is very fast memory that can be located in the
processor. Cache reduces the average time required for the processor to get
the data it needs from the main memory by storing recently accessed data in
the cache.
CMOS memory - Complementary metal oxide semiconductor memory.
CMOS memory is memory that is retained even when the computer is
turned off. The Setup program settings and other parameters are maintained
in CMOS memory.
Default - The option that the software or system uses when you have not
made a choice yourself.
Disc - A compact disc (CD).
32
Gateway ALR 7200 User’s Manual
4076.book Page 33 Wednesday, January 6, 1999 3:48 PM
Disk - The device used by the computer to store and retrieve information.
Disk can refer to a diskette or a hard disk.
Diskette - A removable disk, also called a floppy.
Hard drive - The drive installed inside your computer that stores all your
system and data files. Depending on its configuration, the computer may
have more than one hard drive. Each drive is assigned its own drive letter. If
you have only one drive, its drive letter is C, and it is often called “the C
drive.”
I/O - Input/output. Refers to devices, such as printers, whose purpose is to
enter data into a computer or extract data from a computer. An I/O device is
accessed through an I/O address: a location in memory reserved for the
device to exchange information between itself and the rest of the computer.
IRQ - Interrupt request line. The IRQ is a hardware line that a device uses
to signal the processor when the device needs the processor’s services. The
number of IRQs is limited by industry standards.
Operating system - A program that supervises the computer’s operation,
including handling I/O, networking and connectivity, and device drivers.
Path - A sequence of information that directs the system to the file it needs.
For example, c:\windows\bubbles.bmp is the path to a graphics file on
your system. The c: tells the system it is on the C hard drive, the \windows
tells the system it is in the windows folder, and bubbles.bmp is the file.
Pixel - A pixel is an individual dot in a graphic displayed on your computer.
Pixels are so close together that they look as though they are connected.
POST - Power-on self-test. POST tests your computer’s components
whenever you turn on the computer.
Programs - Software installed on your system. Programs are sometimes
called applications.
RAM - Random access memory. RAM is the computer’s system memory.
You can write to and read from RAM. Information stored in RAM is
temporary and is erased when the computer is turned off.
Appendix

4076.book Page 34 Wednesday, January 6, 1999 3:48 PM
Refresh rate - The refresh rate is the rate at which the image on the monitor
screen is rewritten to the screen. A fast refresh rate helps keep the image
from flickering.
Resolution - The resolution is the sharpness or clarity of the image on the
monitor screen. Resolution is measured by the number of pixels the screen
can display. For example, a resolution of 800x600 means that the screen can
display 800 pixels in a row and can display 600 rows. The more pixels
displayed, the higher the resolution and the clearer the images.
ROM - Read-only memory. Permanent computer memory dedicated to a
particular function. For example, the instructions for starting the computer
when you first turn on power are contained in ROM. You cannot write to
ROM.
