Dell not starting and figuring out A B C D error codes Horus Los AngelesRegistered User regular July 2008 edited July 2008 in Help / Advice Forum Friend asked me to fix his computer. Under his explanation the computer showed a screen saying Unknown Disk. When I started looking at the computer it did not boot at all. All I get is the LED light sign it is getting electricity and after few minutes I get two consecutive beeps. I found on google about the A B C D led lights on the back of the computer. So far I got the sequence and a translation but was based on the XSL Dell models since I don't know what model is my dell. It looks like those corporate Dell computers the big kind. It was made during Windows 2000 so its very old. I am wondering if all this is caused by the battery but I can't find on Dell nor google a sign that says "Time to replace internal battery" A B C D - Memory A B C D Does not list this light order A B C D Expansion Card A B C D Does not list this light order A B C D - Floppy or HD problem A B C D Does not list this light order A B C D Memory configuration “You have brains in your head.

Find the service tag. It will be on a label somewhere on the computer. You may have to lift up the plastic flap in front to find it. Or it might be on a barcode label on the back. It'll be a seven-digit sequence of numbers and letters, like A123BDE. Then go to Dell's Support site and enter the service tag number. That will tell you the model of your Dell. The light sequence is more or less useless without knowing the model. Feral on July 2008 Evi
