Might not be a bad idea to buy another laptop (cheap) and just boot it up once a month to make sure you can use it, and if your system dies, then just pull that one out and use it while Apple RMAs your primary. If the cheap laptop doesn't have enough power, just connect to an Amazon Workspace or something and use that until your normal laptop can work again.
