Latitude D520 CPU Upgrade
I purchase a lot of Dell Latitude D520 Laptops and keeping one for myself and I want to upgrade the cpu to the T7200 cpu. I have emailed Customer Support and gave them the service Tag number and ask what intel duo2 core cpus will work, they informed me that the T5500, T5600 and T7200 will work in my D520. I purchased a T7200 cpu and installed but I get no video or anything so I have updated the bios to 08 and still get the same thing. However I have pc2-4200 ram533mhz. I have just purchase 2gb of PC2-5300 667mhz ram.
I would like to ask if anyone can give some insight as to why the T7200 cpu seems to not want to work in the laptop, I mean is there something I am doing incorrect and something that I have not done that I should be?
I would appreciate any asisstance you guys can help me with.

Unless the CPU you bought is faulty, it will work.

no it will not work,
a T7200 cpu is a dual core, some D520's do not support dual core regardless of the BIOS, it is the chipset, some have the 945GM which supports dual core and some have the 945GML which does not support dual core
check this:

hope this helps
I did extensive research on this because I own a D520 that does not support the dual core very frustrating (no help from DELL)

Were you able to get your D520 working with the T7200 processor? Let me know, I've got an old one I've been holding onto that might get some upgrades here soon...

Did you end up rerouting the wifi wiring for the half size n6300? I have access to a few DOA D520s and am using one as a dry run before attempting the upgrade on my good D520. The n6300 cards I have found are all half pints and the wiring won't reach the connectors without moving things around a bit.

I actually took the hard route, disassembled my D520 to gain access to the wifi cables and rerouted them. I did jump to the AC 7260 as well ... easy upgrade except for the rerouting of wifi antenna cables but if one is careful in the break down it is easy to do..... just a lot of screws to work with.
I have another 520 that I am thinking of doing a cpu upgrade to a T7600. I don't think the performance increase will be all that great from a T5500 but if I do I'll probably do the wifi in that unit as well ... maybe I'll just buy the extension cables and save myself some trouble!
Thanks for the reply!
