Dell 5100C specifications Beep Codes, Code Cause

A possible graphics card failure has occurred.	• If the computer has a graphics card, remove the card, reinstall it and then restart
	the computer.
	• If the problem still exists, install a graphics card that you know works and restart
	the computer.
	• If the problem persists or the computer has integrated graphics, contact Dell (see
	your computer Owner's Manual for information about contacting Dell).
A possible floppy or hard drive failure has	Reseat all power and data cables and restart the computer.
occurred.
A possible USB failure has occurred.	Reinstall all USB devices, check cable connections, and then restart the computer.
No memory modules are detected.	• If you have two or more memory modules installed, remove the modules, reinstall
	one module, and then restart the computer. If the computer starts normally, reinstall
	an additional module. Continue until you have identified a faulty module or reinstalled
	all modules without error.
	• If available, install properly working memory of the same type into your computer.
	• If the problem persists, contact Dell (see your computer Owner's Manual for
	information about contacting Dell).
Memory modules are detected, but a	• Ensure that no special memory module/memory connector placement requirements

exists.	• Verify that the memory modules that you are installing are compatible with your
	computer (see "Memory").
	• If the problem persists, contact Dell (see your computer Owner's Manual for
	information about contacting Dell).
A possible expansion card failure has	1. Determine if a conflict exists by removing a card (not a graphics card) (see "Cards")

	2. If the problem persists, reinstall the card that you removed, remove a different card,
	and then restart the computer.
	3. Repeat this process for each card. If the computer starts normally, troubleshoot the
	last card removed from the computer for resource conflicts (see "Resolving Software
	and Hardware Incompatibilities" in your computer Owner's Manual).
	4. If the problem persists, contact Dell (see your computer Owner's Manual for
	information about contacting Dell).
Another failure has occurred.	• Ensure that the cables are properly connected to the system board from the hard
	drive, CD drive, and DVD drive.
	• If there is an error message on your screen identifying a problem with a device (such
	as the floppy drive or hard drive), check the device to make sure it is functioning
	properly.
	• The operating system is attempting to boot from a device (such as the floppy drive
	or hard drive); check system setup to ensure that the boot sequence is correct for
	the devices installed on your computer.
	• If the problem persists, contact Dell (see your computer Owner's Manual for
	information about contacting Dell).

operating system.

Beep Codes

Your computer might emit a series of beeps during start-up if the monitor cannot display errors or problems. This series of beeps, called a beep code, identifies a problem. One possible beep code (code 1-3-1) consists of one beep, a burst of three beeps, and then one beep. This beep code tells you that the computer encountered a memory problem.

Code	Cause
1-1-2	Microprocessor register failure
1-1-3	NVRAM read/write failure
1-1-4	ROM BIOS checksum failure
1-2-1	Programmable interval timer failure
1-2-2	DMA initialization failure
1-2-3	DMA page register read/write failure
1-3	Video Memory Test failure
1-3-1 through 2-4-4	Memory not being properly identified or used
3-1-1	Slave DMA register failure
3-1-2	Master DMA register failure
3-1-3	Master interrupt mask register failure
