Just to give you a heads up Linus, Dell (and also HP) provide full service manuals for their laptops:

No need to use iFixit.
Congratulations Linus! I remember watching you recover that dead AMD CPU when the pin was broken on NCIX - then discovered LTT from there. Definitely a massive change from back in the day.
