Ein Kommentar
The disassembly of the machine goes way too far. Due to my experience it’s enough to remove keyboard, palm rest/ touchpad unit (only unscrew it and set a bit aside from fan) and fan (there are different versions, long/ short). Then you can exchange/ replace the CPU an reassamble all the stuff. This shortens the time needed to about 10 to 15 minutes. Don’t forget to add some thermal compound to assure heat flow between CPU and fan. I needed to replace a Banias with a Dothan CPU to have the NX CPU flag available. NX is a prereq for Windows 10.
You need to remove the battery, hard drive, and UltraDrive before starting step 1.
