Thinkpad T400 won't start just beep 1-3-3-1

I have a thinkpad T400. Couple of months ago the problem started. I could not shut it down it just keep re-booting. I had to press and hold the start button to shut it. Now it won't boot at all. It beeps 1-3-3-1 and just sits there. When I press start button all lights come ON for a while and after only battery , AC and Ready lights stay ON. Here are few things I did so far without any luck:

 

1. Removed battery and AC adaptor waited few minutes put it back - same problem

2. Removed CMOS battery. DIMM cards waited for ten minutes replaced - same problem

 

tried with swapping  DIMM cards - when I put only one card on top slot it says put the card on zero "bottom" position. After placing the Mem card on the bottom slot no thing happens. It beeps again and sit.

 

When I checked in the manual it says either DIMM or System board. I do not know which one is giving me the problem. I just do not want to replace all parts without knowing. Can any body help please or had similar issue and solutions if you managed to solve it. Thank you.

If you tried both DIMM cards you have in the bottom slot, it sounds like tyhe system board, assuming they were seated correctly

Assuming it is system board, do think it is wise to replace or buy a new PC?

if it is a system board, then a replacement board can cost between 200 to 400 dollars, not including labour costs (assume you can do the replacement by yourself).

Try the RAM elsewhere, if it works, then it'd be the systemboard.

You can try to clean DIMM contacts.  Is it still under warranty? If so, it is time to use it. If it is not, do you have integrated or discrete video?

Could you post your model number from under the laptop? It should be of the form 1234-ABC.

The only number I found under the laptop is :
Type 2764 CTO S/N xxxxxxx 09/06
Is this what you are looking for?
