Hi @ninjasquid,
Unfortunately, most manufacturers do void the warranty if the device is opened for repair outside their "control". Most countries has certain laws about what does in fact void a warranty, but until the Right to Repair comes through, we're all a bit stuck in limbo.
Some devices have stickers saying warranty void if removed or damaged, but those are far from as normal as they used to be. I always assume that (I live in Norway and we have pretty decent laws protecting the consumer) I void the warranty if I open it. Warranty is normally 2 years over here, but some things have a 5 year warranty.
