I work in IT and deal with people spilling shit on their laptops all the time. This is precisely why I tell them that im not saying their shit is broken, Im saying they cant depend on it. Right now it might seem fine. Once whatever drop of liquid manages to corrode whatever random trace enough to break the connection, it wont. That day could be tomorrow, that day could be 10 years from now, or even never!
But the important takeaway from the conversation isnt that the laptop is broken, the key takeaway is when it stops working right, IM NOT PUTTING TIME INTO FIXING IT. Replace it, or dont...but dont call me on that day because the answer then is going to be the same as now...replace it. If you dont want to replace, goto 10. Thank you, have a nice day.
That being said, I'll use those things for noncritical shit all day long. I dont care if it shits the bed...I just grab another piece of shit off the shelf and make that the new bed shifter. But my plex server taking a dump is not the same as your CAD workstation taking a dump mid project, obviously.
