Power Light State	Description
Off	Power is off, light is blank.
Blinking Amber	Initial state of light at power up. Indicates system has power, but the POWER_GOOD signal is not yet active. If the Hard Drive light is off, it is probable that the power supply needs to be replaced. If the Hard Drive light on, it is probable that an onboard regulator or VRM has failed. Look at the diagnostic lights for further information.
Solid Amber	Second state of the light at power up. Indicates the POWER_GOOD signal is active and it is probable that the power supply is fine. Look at the diagnostic lights for further information.
Blinking Green	System is in a low power state, either S1 or S3. Look at the diagnostic lights to determine which state the system is in.
Solid Green	System is in S0 state, the normal power state of a functioning machine. The BIOS will turn the light to this state to indicate it has started fetching op-codes.

I'm having the same problem with my XE. 2 days ago the power, 1 and 3 lights started flashing and it wouldn't power up. After an hour the lights went out and it functioned normally. Yesterday the same 3 lights started flashing when the comp turned itself off, and it took nearly 24 hours for them to go out. I'm nervous about trying to power it up again, I don't want to damage the machine. Any help would be greatly appreciated

Sweden!

I know that this is user forum. I just write here because I just want to know if other users have the same problems with XE machines.

I won't get that information if you call Dell support ;)

I mean: You I won't get that information if you call Dell support ;)

We have about 200 Optiplex XE computers. Recently, several broke (about 50).  Both diagnostic lights 1 and 3 has begun blinking + the power button blinking with yellow light. We got info from Dell that they had problems with faulty power supplys, but that this faulty PSUs wont be shipped anymore. They have begun to replace both the motherboard and power supplys when a computer broke. But recently many of this computers have broke again. Are there others who have experienced the same problem with optiplex XE computers?

Dell OptiPlex XE - Documentation

We're having the same problem with XEs in our company in the Caribbean.  All started failing around the same time with error code 1,3 late 2012.  Standard replacement procedure is to change mobo and psu.  Before the problem started happening to a lot of our systems we discovered that Dell has discontinued this model for our region.  It is extremely annoying to have so many failures.  If it is a widespread problem Dell should be replacing with an alternate system.
