Troubleshooting
First steps
Try these steps first before going to the following sections:
• Make sure that the power cords are connected to your server and an AC outlet and that
the AC outlet is supplying power.
• If you use a surge protector or a UPS, make sure that it is turned on and is rated to handle
the power required by your server.
• If you added or removed server components before the problem started, review the
installation procedures you performed and make sure that you followed each instruction.
You may need to remove the device, uninstall the device’s software, then reinstall the
device.
• If an error message appears on the screen, write down the exact message before calling
Gateway Customer Care. For instructions, see “Telephone support” on page 62.
• Restart your server, then open the BIOS Setup utility by pressing and holding F2 while your
server restarts. Check your configuration settings.
• When diagnosing problems, press the non-maskable interrupt (NMI) button to put the
server into a halt state. For the location of the button, see “Control panel” on page 2.
• If an error occurs in a program, see its documentation or online help.
Battery replacement
If you have problems after installing a new CMOS battery, try each of the following items, closing
the case and restarting the server after each try:
• Restart your server, then open the BIOS Setup utility by pressing and holding F2 while your
server restarts. Correct any discrepancies.
• Remove the back top panel by following the instructions in “Opening the server case” on
page 25, then make sure that all cables inside the case are attached securely. Also, make
sure that the colored cable edges are aligned correctly and that the connectors do not miss
any pins.
• If you have the correct test equipment, make sure that the new battery has power.
Although unlikely, your new battery may be defective.
Beep codes
Whenever a recoverable error occurs during the power-on self-test (POST), the BIOS displays an
error message that describes the problem. The BIOS also sounds a beep code (one long tone
followed by two short tones) during POST if the video configuration fails (a faulty video controller)
or if an expansion card is not functioning correctly. One short beep indicates the BIOS will boot
the operating system. No error found.
A PCI expansion card (for example, a RAID controller) can also issue audible errors by itself, usually
consisting of one long tone followed by a series of short tones. For more information on the
beep codes issued, check the documentation for that device.
The following table shows POST error beep codes. Prior to system video initialization, BIOS uses
these codes to inform you of error conditions.
Warning
To avoid bodily injury, do not attempt to troubleshoot your server problem if:
- The power cords or plugs are damaged
- Liquid has been spilled into your server
- Your server was dropped
- The case was damaged
Instead, unplug your server and contact a qualified computer technician.
