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.

  • Using your fingers, lift up the keyboard to a 30 degree angle.

  • Carefully pull the keyboard toward the LCD screen to release the tabs along the bottom edge of the keyboard.

  • Now you can gently flip the keyboard over so the keys are resting on the track pad and the keyboard connector is exposed. Be sure not to pull on the keyboard cable.

  • Before we continue, disconnect/remove the following.

  • Hard drive

  • DVD drive

  • Disconnect the CMOS battery. You will have to re-enter the time and date, as this battery is what keeps the clock ticking even with out power.

Add Note Edit Step 14  ¶ 

  • Loosen screw 1

  • then 2

  • then 3

  • then 4

  • 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 completely with out the other screws loosened may damage the logic board.

  • The red square is around the south bridge

  • The blue square is around the chipset. the chipset combines the north bridge and Intel GMA 950 into one die. the entire chipset is called the intel 945 GM.

  • The heat sink uses thermal paste and pads.

  • Green square is the slimy thermal pad
