Depending on how much liquid was spilled, which components were affected by the liquid, and how fast you were able to shut it down immediately the above suggestion may work or may be a complete lost cause.
Hopefully, the above will work, but be prepared for the possibility the liquid got into critical components while still powered on and thus, short-circuited the motherboard/other electronic components permanently.
IME, had examined some machines which only needed the replacement of the keyboard/touchpad/power button. Others were a total loss even after 72 hours of drying out because the spilled liquid got to the motherboard/critical electronic components before the owner had a chance to completely shut down the machine and cut power off.
How long do you plan on using the new machine when you get it? How old was the machine which had wine spilled on it?
If you go too cheap, the main issues could be inadequate amount of RAM with no possibility to upgrade as a friend is now finding out after going against my advice last year and jumping on a $200 “good deal” on a low end dell inspiron which is maxed out at 4 GB RAM. He’s now finding the machine frequently gets bogged down due to lack of RAM when he uses basic office applications to work from home or on the road. The processor, while not bad for his intended uses is basically a slightly updated version of a processor which was released nearly a decade ago.
Not to mention the build quality of that notebook is a bit on the flimsy side and I already saw some signs of a developing crack on part of the plastic casing. Very disconcerting considering he tends to be very careful taking care of his stuff.
There’s also a higher likelihood you may need to send a budget/consumer-line notebook…especially the lower end ones back for warranty repair multiple times due to poorer quality control from the manufacturer for that particular line. Even if it’s covered within the warranty repairs, the downtime and hassles involved aren’t insubstantial for many users.
I think you really mean 8 GB which I agree is the bare minimum to get nowadays even for basic office tasks to ensure some futureproofing. Especially if you plan on using it for more than a year or two.
BTW, haven’t seen a machine with 8 Megs of RAM since the early to mid-'90s. Was great in the early part…considered inadequate by the mid '90s.
