No teardown guide on #iFixIt for the #HP645 G1, but the official #HPSupport channel on #YouTube has videos for the G2, which afaik is fairly similar.
Looks like it's supposed to be fairly spill-proof, and as I didn't really see much liquid underneath the keyboard, I'm going to assume it's survived alright.

The missus, @Siiw, was so kind to go out for a long walk this morning to pick up the #HP645 #laptop for me while I watched #BeardGrabber. :D
It definitely needed a bit of cleaning, especially on the outside, but so far it works quite well. :) Well enough at least that I can finally sit down on the sofa again, write some code and browse sites on a 14" screen rather than on my phone, with much less overheating issues.
I do think this one could do with some dust removal too, but I'll fix that later

I'll first run it with the Windows install that comes with it, to make sure all the hardware works without issues, and then I'll probably set it up to dual boot with #Linux to get a bit more power out of it.
I just hope this #HP645 model works out of the box without much issues under Linux (or #BSD if necessary?). Didn't see much worrisome on #LinuxProbe at least.
