Anecdote:
My employer recently bought me a Lenovo Legion 5 Pro. Due to concussions and general flicker sensitivity, I don't do well with 60Hz screens, and I prefer AMD CPUs. This one came with a 240Hz screen. Overkill!
But... Bluetooth was unreliable. Every few hours, it vanished from Windows as if it didn't exist. A moment of sleep and wake was enough to bring it back, but it was still annoying to lose mouse and headphones unexpectedly.
Two support calls, but all they did was reinstall a bunch of the driver updates I had already reinstalled (and they installed Geforce Experience because Vantage said it was available.) Unsurprisingly, none of that fixed the issue. The next step was a factory reset and/or replacement, which would've been a big PITA because of time I already spent doing setup. And it still might not have solved the issue.
Instead, I spent $23 on an Intel AX210 WLAN/Bluetooth chip, and performed the replacement (of a Realtek chip) in well under 10 minutes. Taking off the bottom panel was relatively easy, and I did not see any damaged clips. M.2 and SODIMM chips are readily replaceable, and so was this WLAN chip. It also fixed my problem completely without resorting to losing a lot of time repeating my setup.
If there's a point, it's that budget and mid-range gaming laptops are often quite repairable, where as thin and light / ultrabooks, especially those made for businesses are much less frequently repairable. I think the reason is two-fold... in general businesses will just pay for repairs, even when it means sending a device back. And of course smaller machines tend to get soldered components and optimize for size instead of access.
You have to think about the compromises you're willing to make, or to have built into your purchases.
