Water went through the keyboard: the first five minutes decide the machine

Liquid and laptops have a well-known ending and an equally well-known rescue, and most people get both slightly wrong in the minutes that matter. The physics: water itself does little to a board in an hour; what kills laptops is the conductive path - water bridging pins that should never touch while power is still applied, and then corrosion eating the traces whether powered or not. Every correct action below attacks one of those two; every wrong one feeds them.

The order that gives the machine a chance

1. Kill power now, not politely. Unplug the charger, then hold the power button for fifteen full seconds - a proper shutdown leaves the board energised for tens of seconds of menu farewell, and that is the window the short spends. No "let me just save the file": a dead board saves nothing.
2. Flip and drain through the keyboard. Open the lid, turn the whole machine upside-down in a tent over towels so gravity takes the liquid back out the way it came. Spilling while it lies flat means the water went through the keys onto the board; draining keyboard-side is draining it away from the board.
3. Battery out if it comes out. Removable packs, unlatch and pull. Internal batteries on modern machines stay - the upside-down hold covers it; this is the honest difference between the two laptop eras, and why thin-and-glued is harder to rescue.
4. Airflow, shade, no heat. A fan blowing across the open keyboard, in a cool room, for hours. A hairdryer on hot is its own way to melt keys and push water deeper into seams.

Rice, alcohol, and the two-day rule

Rice absorbs nothing where it matters and introduces dust and starch into ports where it does; the desiccant that works is silica gel - the packets from the shoe box, a dozen of them under the open lid overnight - or simply dry air and patience. The thing the service benches actually do is the rinse: high-percentage isopropyl alcohol (90 percent plus, and the "phone screen cleaner" in the drawer is not it) flows where water flowed, displaces it, and - unlike water - evaporates without leaving conductive residue; technicians bathe spilled boards in it deliberately. On a keyboard-only spill on a machine whose back panel opens with a screwdriver, the alcohol is a fingertip-brush job on visible surfaces and nothing else - do not start surgery beyond the screws your confidence reaches. Then the rule that separates machines that live from machines that die twice: stay powered off for a full 48 hours (longer in humidity) before the first power attempt, because the board that boots "fine" on hour two with trapped water is on a timer - the corrosion stories nobody escapes are the ones with a working second week.

The honest odds, by what was spilled

Water, quickly drained: genuinely good - most survive the ritual above, and if anything dies it is the keyboard, a parts-laptop-cheap repair on serviceable models. Sugary or sticky (soda, malt, the cup of tea with sugar): assume the residue will keep corroding whatever the drying does, and get a bench cleaning within the week - tap water off the keys does not reach under the board shields. Anything with a lid and a fuse (the sweet drink you spilled with the charger in - the combination nobody admits to): the short is already done, and the odds fall for the charger's circuit too - test the charger on a phone before trusting it back onto a rescued laptop. And the insurance truth worth knowing before the next spill: liquid damage is exactly what the standard warranty never covers - the machines that get rescued are the ones somebody kept serviceable, which is another reason the buying desk keeps saying thick and screwed beats thin and glued.
