Hi

During the weekend I received my replacement motherboard for my old failed motherboard (no power)
The old motherboard is 63Y1505
I ordered a 63Y1551 + and put a i7-720QM from ebay (it was pulled from a working Lenovo)in as to my understanding it should work as long as I don't use the old dual core CPU.
Unfortunately it just gives away one long beep and two short beeps when I try to boot it.
I've just hooked it up with the bare minimums, cooler, keyboard and LCD assembly.

What I've tried:

- Tested the old DIMM in another laptop (comes from the old 63Y1505 board originally so it should be compatible)
- Tried a new DIMM from a T530
- Tried hooking up an external monitor to the VGA port

Am I missing something here or should I just assume that the new board is DOA?

One thing to try is to remove all memory and see if the beep codes change on turn on.

If you haven't already done so the hardware maintenance manual can be downloaded here.

The beep codes are different when no DIMM is installed
it plays alot more beeps, I can give you the exact pattern when I get home.

I forgot to mention that the screen is blank both on the integrated LCD and on the external monitor.

One long followed by two short beeps is the code for video card error.
I think you got a board with a dead GPU.

The normal beep code for missing or bad memory is 1-3-3-1. One short beep, followed by a slight pause, 3 short beeps, pause, 3 short beeps, pause, 1 short beep.

Yeah that sounds like what it's doing when I remove the DIMM - at least it registers the DIMM then

I'm gonna contact the seller and work something out, I don't think I'll get the board to work
