T410 - Won't start up.

Question

I was given a T410 from a business. They had used it for several years without issues.

Starting with the power button does nothing. There is a single green light on the mother board.

Holding the power supply test button gives me lights 1 2 and 4 on the front.

Need to know what that means.

1. Moved memory around and went to 1 stick - no change.

2. Ordered and replaced power supply button/module. no change.

3. Ordered another motherboard - no change.

4. Borrowed a power supply for it - no change.

5. Tried a PCI Express video card - no change.

5. Went down to basics. No cards, 1 stick memory. no change.

Holding the power supply test button down causes drives to spin and controller starts blinking.

Anybody know what those combination of lights means.

Help!

Crossbow11,

The first thing I would do is to take the server to its Minimum to Post hardware configuration, which is removing everything internally and externally but the following;

•System board
•CPU1 (Min for troubleshooting)
•Heatsink for CPU1 for prevention of over-heating
•One memory DIMM in DIMM A1 for CPU1.
•Power Supply (PDB is required for redundant PSU)
•Control Panel

If the server starts like that then I would individually add the removed devices back until the issue reappears, identifying the cause of the issue.

Let me know what you see.

Hi, Chris H

I have completed that and no change.

Fans and hard drives spin up while pressing the power supply test button on the back. (single power supply)

Do you know what that combination of lights means?

Hello,

The 1, 2, & 4 combination isn't recorded in the reference material I'm looking at. The only 3 digit codes I see are 1, 2, and 3, 2, 3, and 4, and 1, 2, and 4. 1, 3, 4 indicates a failure with the system board. The other two codes would relate to ancillary hardware.

If you're seeing the system fail to POST while at the minimum to POST configuration, you might consider testing with an alternate DIMM installed. You might also test with an alternate processor, if you have one available.

I transcribed it incorrectly. Repeating numbers can throw me off. The 3 digit codes we have are: 234 134 123   134 is the board error.

DylanJ   You have that combo I need in your first line.     'The only 3 digit codes I see are 1, 2, and 3, 2, 3, and 4, and 1, 2, and 4. '   Is the problem the motherboard,  power supply or processor?

Hey. I'm new here! I know this thread is old, hope I'm not breaking some rule, but I'm having the exact same issue and you seem to be one of the few people who have encountered it and posted about it online... at least according to Google. I was wondering if you were ever able to get the machine to complete POST? Also, as a side note, in my search for answers I removed the CPU in my particular unit to find that some pins in the socket were seemingly bent. Do you remember if you inspected the CPU socket(s) and noticed anything amiss?
