Hello. I have this odd problem in my Dell Latitude D520 core2duo where one of the memory slots isn't working anymore. Just yesterday the Laptop would not startup but lights on the front panel came on, so I suspected a memory issue. The D520 has a slot underneath the keyboard for memory, as well as underneath the laptop. When ever I put memory in the slot under the keyboard, it won't startup. I tried various memory known to work. I even took the memory from underneath the laptop and placed it under the keyboard because it worked underneath. But once I placed the memory in the slots under the keyboard, it would not startup. I would just get three green lights next to the power key. One stayed, the other 2 blinked; they all eventually stopped entirely. Once I removed the memory, it would start up. I tried cleaning the memory slot with an air can. I've never encountered this before. For now, I just run with 2 gig memory stick underneath the laptop. It works fine. I am assuming a motherboard issue. Any suggestion greatly appreciated.

Sure sounds like the socket is bad, or the memory controller. You may have to live with a single DIMM in the bottom slot.

The Dell Latitude D520 laptop supports up to 4 GB of RAM - up to 2 GB in each slot.

This is the recommended 1 GB and 2 GB module for it:

200-pin DDR2 PC2-5300(DDR2-667), 1.8 volt, CL=5, unbuffered, non-ECC

^^^ This guy really knows his stuff. So very helpful. I think he replied to my thread too with something equally as relevant to what was in my post.

The same thing happened in my old laptop after I tried installing a version of Linux (Damn Small Linux.) No idea why or how it happened, but I was forced to just live with one stick of ram for the remainder of the time I kept it. I don't know for sure, but I'd imagine the laptop is build in a rather 'proprietary' fashion and it would be extremely difficult to fix the issue yourself because it most certainly is the hardware/motherboard.
