Dell Latitude Palmrest Removal

I’m using an old plastic gift card to pop the palmrest loose. It starts best up near screen area, and work towards the “front” touchpad” area. From has some inner clips, so you have to left up near screen and tilt back towards front touchpad area to remove the palmrest.

What it should look like, cleaned off.

Old thermal crap ,cleaned off cpu and heatsink

Fresh Arctic Cooling MX2 thermal compound applied to CPU

 

 

Laptop re-assembled, temperature after repair:

Idle Temp = 42 46 celsiusDell Latitude D630 Cooling Repair

Load Temp ( 2 hours under full load) = 62 celsius

———————

Before repair idle temp was 66-68, load temp was 92++ celsius
 
 
That is more than a 30 degree drop in temperature!

 

The main heat source is the CPU, the heat building up inside of laptop was due to the blocked heatsink exhaust (3 photos up)

Dell Latitude D630 Graphics Chip

Video Graphics Chip > Yellow Highlighted Square in photo >>>>>

The Dell Latitude D630, as 95% of most laptops has a integrated video graphics chip, which means it is part of the motherboard. Graphics chip cannot be changed out or repaired if the heat has damaged it. Entire motherboard needs replaced. And that will be hard to find at a cheap, reasonable price, maybe on ebay “used or refurbished” but still very high priced compared to a desktop motherboard. Connect an external monitor, switch over to external if you have a good display on external, graphics chip is fine. Your screen, or power inverter, or video cable, or connectors are at fault (or a combination of all 3) to the laptops display. IF your external monitor when connected to laptop after key switch over is black, no display your graphics chip is most likely at fault, or bad memory module.

This laptop is probably several years old, duo core still a good laptop. Installed new drive and fresh install so this laptop will last a long time now. That heat would of killed this laptop for sure!
