I know you can’t update if you have no internet…I’m not that silly 
But, my laptop lost it’s internet about two weeks ago(the button to turn the wireless on won’t work) and I’m using my netbook now.
Is there any way that I can update my laptop through my netbook?
You won’t be able to use the update function to update Scrivener, but you could always download the latest version from the website to a usb stick (from your netbook or you could swing by an internet cafe for 15 minutes if that’s not an option) and then install the newer version from that - uninstalling your old scrivener version before installing the new one would be cleaner, but I don’t think it’s absolutely necessary.
Otherwise, I’m pretty sure there’s not.
