Dell M4700 REBUILD #2 - (Thermal) Grease is the WORD!
In Episode 2 of the CRAZY Dell M4700 Saga, instead of putting the machine back together - I take it even more apart.
Why, you may ask?
Well, because the old heat sink compound (grease) on the GPU daughter card was so very crusty and burned.
Thermal Grease isn't supposed to look like a fried egg!
Considering this situation with respect to the GPU, it was pretty clear to me that the laptop probably needed its Thermal Grease freshened everywhere, including the CPU area. Time to break out the screwdrivers, and dig even further into the guts of CRAZY!
What we are trying to do is:
1) Determine the probable conditions that caused CRAZY to fail
- My guess is CRAZY overheated because its heat dispersal system was blocked with lint
2) Pinpoint exactly which component or sub-system is in a failed state
- My guess is some part of CRAZY's graphics subsystem failed
3) Remediate, Repair and/or Replace the failed component or sub-system
- The first thing I did was to remove the lint from the heat dispersal system, which resolved the problem short-term
- What I am doing now is attempting a longer-term fix by digging even deeper into the heat dispersal system, to the point where the GPU makes contact with its heat pipe.
4) Prevent this (or a similar) component or sub-system from failing again in the same place and way, or a similar way
- While digging deeper into the GPU failure, a concern about a similar, heat-related failure with respect to the CPU has cropped up, so I am also replacing the Thermal Grease on the CPU out of an abundance of caution.
Seeing as one of the major enemies of laptops is heat, and considering that I already had the machine open, it made sense to me to also freshen its CPU Thermal Grease, considering that the existing stuff had been in there, untouched, for almost a decade!
