Introduction

The Dell latitude D620 was introduced in March 2006. Both the first MacBook Pro, and this Dell Latitude D620 have the same Intel core duo T2300E. Like the first MacBook, they both have Intel's GMA 950 graphics.

  • Do not completely loosen a screw.

  • Loosen each screw a little bit. Going from 1 then to 2 then to 3 and then to 4. Keep doing this until they are all loose.

  • Loosening one screw without the other screws may damage the logic board.

Wow, great pictures from a cell, I thought you were using a digital camera like a kodak or something

Seems like it would make a perfect "Hackintosh."

Yes. It does indeed. I've been using it as a hackintosh sense early February. I had Mac OSX 10.6.2 on it, even before I performed this tear down. I was able to use software updater to go strait from 10.6.0 to 10.6.2. Skipping 10.6.1. I've only had a few kernel panics. I've even been using the iPhone SDK. It is a very stable hackintosh. The GMA 950 can even play The SIms 3 w/o any issues.

Fantastic guide!! Thank you for taking the time and effort to create it!

There is a little flat, white, Multi-wire connector in the upper-left corner.

I suspect that this is where the optional Bluetooth module would be located, can anyone confirm this?

Thanks,

Tim D.

Yes, the flat white connector on the left side above the keyboard is for the optional bluetooth connector. It interfaces via USB.

Nice guide! I just resurrected an old D620 that was on the pile, that I occasionally use for one piece of ancient code. I've disassembled, aired out the dust, and cleaned it. Replaced the non-functioning Dell battery with an OMCreate aftermarket battery.

This is a Core 2 Duo 2.3 GHz. Upgraded the HDD to a Hitatchi 320 GB SATA3 that was sitting here. Even though the D620 only has a SATA1 interface, might pick up a SSD, just to give it some more life. I did a clean install of Win7x64 bit + SP & patches (Nov2016), used the Dell's Vista nVidia NVS 110 video driver (File = R142931), installed and worked great.

I went ahead and ordered a replacement keyboard, since it has some sticky keys & a missing key cap. Also 2 x 2GB SODIMMs. That should give new life to this 10 year old notebook and keep it out of the landfill for at least another 4-10 years.

Thanks Nicholas & iFixit for the inspiration!
