@lanodan @ocean @coolboymew @birdulon all of those are kinda things where if it's old enough to be out of warranty, it's probably time to e-waste it
could i look up the manufacturer's procedure to disassemble it, locate a part number, track down a place to order it from, and then put it back together with the new one? sure
but with the amount of time it'd take times my billable rate (or even desktop support's) for a 3+ year old laptop? nope you're getting a new one.
