What does the Dell Power lights mean?

Saturday, August 25th, 2012

Recently, I was asked what the amber 4 light meant and I had a machine which was flashing the 1 and 3 light. These could be found in a service manual, but who keeps those let alone read them these days.

A quick check of the Dell site found a document on diagnostics.

The 4 light meant a system was in recovery mode after bios pulled a checksum error.  A quick correction eliminated this condition.

The flashing 1 and 3 light was a bad PSU. A service call was made for this particular machine.

Shall I keep a service manual now?  Probably not. If I do, then this problem will probably never happen again. 😉
