Well... yeah, if you can snag a new one and just keep the busted one as an at home system that would definitely be the far superior way to go.
I don't know if your a tech or if you've ever tried to repair a laptop before but if not... it is REALLY not something you want to mess with unless you really know what you're in for.
I used to refurb all sorts of crazy things electronic and otherwise at my old job. I am not a tech at all but I was pretty good at taking a pile of smashed up junk and putting together working units. Did it for years.
Laptops? Oy. I got ahold of a couple rather simple old PC lappies many moons ago. One I used for years and the second (which was kind of bashed up but worked) I kept around as a backup for parts. I could swap out the drives and more modular parts easily but some of the more finicky internal stuff started going bad on the one I used all the time.
No problem, right? I'm a handy dude and I've got the parts. I looked up all the info I could find about replacing stuff on that model and went to work.
Long story short I spent an entire day trying to rip these stupid things apart and just ended up with a pile of crazy little screws, plastic bits everywhere, two half mangled laptops with ribbon cables poking out willy nilly, torqued bezels, screens, keyboards, whatever.
It was brutal. Tons of stuff was glued and/or soldered permanently by the manufacturer, certain screws would not budge or when I removed them a ton of tiny pieces became disconnected, I probably ruined contacts and chips mucking around and I essentially stopped before I did any REAL damage to the units.
So yeah... f*cking laptops. Wicked awesome in so many ways. User repairable? Not so much.
You could of course be a proper tech or good at such repairs but if not I wouldn't even bother. Consider it a desktop and save yourself the headache. Even if you find the right parts just pulling it apart could brick it.
Sorry if that sounds defeatist but they are a nightmare.
The better option between the risk of self repair and expense of buying a new one would be just taking it to a reputable laptop repair place. Keyword being REPUTABLE. A lot of clownshow outfits claiming to be pro lappy repair but some are quite good. Might want to completely pull your hardrive though if it's just physical repair so you don't have whacko nerds creeping on your personal files. They can use their own hard drives.
