Most of the laptops that come through my shop in Somerville aren't there because of a virus or a failed update. They're there because a coffee went over, the laptop slid off the couch, or someone closed the lid on a pair of earbuds. Those three accidents cover the majority of physical laptop damage I see, and what you do in the first ten minutes after each one decides whether you're looking at a keyboard replacement or a data recovery job. This guide covers exactly what to do (and what not to do) after a spill, a drop and a screen crack, what each repair usually involves, and how to decide whether the laptop is worth fixing.
Water, coffee, soda, wine, a kid's juice box. The liquid matters less than what happens in the next sixty seconds.
A laptop keyboard sits directly above the motherboard, and most laptops have no barrier between them. Whatever goes into the keys drips onto the board, the memory, the storage and the battery connector within seconds. Electricity plus liquid plus the minerals and sugars dissolved in it equals corrosion and short circuits, and the corrosion continues as long as the board stays wet. That's why the old advice to "leave it for a week" is wrong. A week is how long it takes coffee to eat through a trace.
Hold the power button until the screen goes dark. Don't shut down gracefully; the ten seconds Windows takes to close is ten seconds of current flowing through wet circuits. Unplug the charger. If the battery is removable, pull it. Unplug anything in the USB ports.
Open the lid as far as it goes without forcing, and stand the laptop upside down in a tent shape on a towel so liquid runs out through the keyboard, the way it went in. Don't lay it flat on its back; that sends the liquid across the whole board. Blot the keys and any visible liquid with a paper towel.
This is the one everyone breaks. The laptop may well power on and look fine, and every minute it runs wet is more corrosion. If it worked before you pressed the button, it will still work after a technician has cleaned it. If it doesn't, you've just found out the expensive way.
The repair for a spill is a teardown: remove the board, clean the liquid and any early corrosion off with isopropyl alcohol and a brush (an ultrasonic bath for bad ones), check every connector, and replace what's damaged. The sooner that happens, the less there is to replace. Bring it to the shop powered off, with the charger, and tell me what was spilled.
Plain water is the best case: no sugar, no acid, and a laptop that was powered off fast and cleaned quickly often survives with nothing more than a new keyboard. Coffee and tea leave a film that attracts moisture and conducts. Soda, juice and energy drinks are sugary and acidic, which means sticky keys and corrosion that moves fast. Wine and beer are acidic and stain. Milk goes rancid inside the case. If it wasn't water, assume the keyboard is done and the board needs cleaning regardless of how the laptop seems to behave.
A keyboard replacement is the minimum on almost every spill, because the membrane under the keys wicks liquid and the keys start doubling or dying within days. On many modern laptops the keyboard is riveted into the top case, so "keyboard" means the whole palm rest assembly. Beyond that it depends on what the cleaning finds: a corroded memory slot, a damaged charging port, a trackpad that no longer clicks. Boards where the liquid reached the processor's power circuitry are sometimes not economically repairable. When that happens the drive is nearly always fine, and data recovery gets your files onto a new machine. My older post on saving a laptop after water damage has a customer question that covers a typical case.
What breaks depends on what the laptop was doing when it hit the floor.
Laptop cases are engineered to survive being carried, not being dropped. A fall of table height onto a hard floor puts a shock through the whole machine, and the damage shows up in the parts that were under stress at that moment.
| State when dropped | Risk | What usually breaks |
|---|---|---|
| Open and running | Highest | Screen (open lid takes the impact), hinges, a spinning hard drive's heads hitting the platter, display cable at the hinge |
| Open and powered off | High | Screen and hinges; drive is safer with the heads parked |
| Closed and running | Moderate | Hard drive, corner dents that stress the board, charging port if the cable was in |
| Closed and off, in a sleeve | Lowest | Often nothing; occasionally a cracked corner or a bent lid that won't close square |
Laptops with a solid-state drive lose the hard-drive row entirely, which is one of several reasons an SSD is the first upgrade I recommend on any laptop that still has a spinning drive.
If the laptop still turns on, resist the urge to carry on as normal. Go down this list:
Even if everything passes, back the laptop up today. Hairline cracks in solder joints and boards can pass a quick check and fail a week later under heat. If anything on the list failed, bring it in before using it further; a cracked board that keeps running tends to take other parts with it. If a drive was damaged, my post on dropped drives explains why you shouldn't keep trying to read it.
It doesn't take a drop. A pair of earbuds inside a closed lid does it.
Modern laptop lids are thin, and the panel behind the glass is thinner. A crack can come from a drop, but at least as often it comes from pressure: the laptop closed on a pen or earbuds, squeezed in a packed backpack, picked up by one corner of the open lid, or something set on top of it. The outer glass may look perfect while the LCD layer behind it is broken, which shows up as a dark blotch with lines radiating out, a "spider web" in one corner, or a spreading ink-blot patch that gets bigger over days.
A cracked panel doesn't heal and the damage spreads as the liquid crystal leaks from the broken layer. The laptop itself is usually fine: plug in an external monitor over HDMI or USB-C and you'll typically get a perfect picture, which is a good way to keep working (and back up) until the panel is replaced. If the external monitor also shows lines or artifacts, the drop hurt the graphics chip, and that's a different repair.
The panel is replaced with one matched to the laptop's exact model, resolution, connector and refresh rate. On most laptops that's a bezel-off, panel-out job; on machines where the glass is glued to the lid, or the touchscreen digitizer is bonded to the panel, the whole lid assembly is replaced and the price goes up. At my Somerville bench most standard laptop screen replacements run $180 to $275 installed, including the panel, labor, testing and a 90-day warranty. The full breakdown by panel type is in my screen repair cost guide, and if the laptop took a real hit I check the hinges and lid frame while I'm in there so the new panel doesn't inherit the old problem. Your files aren't touched during a screen swap.
Two related situations: black blotches without an obvious crack are covered in my guide to black spots on a laptop screen, and if you're weighing a repair against a new machine, screen replacement vs. a new laptop lays out the math.
Short version: not accidents.
Standard manufacturer warranties cover defects, not damage. Apple's support page on liquid damage says it isn't covered by the one-year limited warranty or the AppleCare Protection Plan; HP's documentation classifies cracked screens and physical damage as outside the standard warranty; Dell calls it customer-induced damage. The exceptions are the accidental-damage plans sold at purchase (AppleCare+ with accidental damage, Dell Accidental Damage Service, HP Accidental Damage Protection and similar), which cover spills and drops for a service fee per incident. If you bought one, use it. If you didn't, an independent shop is usually faster and cheaper than the manufacturer's out-of-warranty repair, and you keep your data on site rather than shipping the laptop away.
Never assume a laptop is beyond repair. Almost any damage can be fixed by replacing parts. The question is whether it should be.
The rule I give customers: if the repair costs less than about half of what an equivalent replacement would cost, and the laptop was doing its job before the accident, fix it. A $220 screen on a two-year-old laptop that cost $900 is an easy yes. A $450 board repair on a six-year-old machine that was already slow is a no, and the money goes toward a replacement plus recovering the data from the old drive.
Three things push the decision toward repair: the laptop is recent, it was fast enough, and the damage is confined to one part (screen, keyboard, hinge, port). Three things push it toward replacement: the board is damaged, the laptop still has a spinning hard drive and under 16 GB of memory, or you were already thinking about a new one. Either way, I'll tell you which side of the line you're on before any work starts.
None of this is complicated. All of it is things people stop doing after the first month with a new laptop.
Spilled, dropped or cracked in the last day or two? Power it off, don't test it, and bring it to Somerville. The sooner it's on the bench, the less it costs to fix.

Hold the power button until it shuts off, unplug the charger, pull the battery if it's removable, and unplug anything in the USB ports. Turn the laptop upside down in a tent shape on a towel so liquid drains out through the keyboard rather than deeper into the board. Don't turn it back on to check whether it works. Get it to a repair shop within a day or two; corrosion starts within hours, faster with coffee, soda or wine than with water.
No. Rice doesn't pull moisture out of a sealed laptop, it leaves starch dust in the ports, and the days spent waiting are days the liquid spends corroding the board. Drain the laptop, keep it off, and have it opened and cleaned by a technician.
Often, yes. Plain water on a laptop that was powered off quickly and cleaned within a day or two frequently survives with nothing more than a keyboard. Sugary or acidic drinks and laptops that were left running or charged while wet do worse, and sometimes the board isn't economically repairable. Even then, the drive usually survives and the data can be recovered.
Back it up today. Drops can crack solder joints, loosen the display cable, and damage a spinning hard drive in ways that show up days later. If you hear clicking or grinding, if the screen shows lines or dark patches, if the hinge feels loose, or if it shuts off when you move it, stop using it and have it inspected.
At my shop in Somerville, most standard laptop screen replacements run $180 to $275 installed, including the panel, labor, testing and a 90-day warranty. Touchscreens, high-resolution and high-refresh panels, and displays that are glued into the lid cost more.
Almost never. Apple states that liquid damage isn't covered by its limited warranty or AppleCare Protection Plan, and HP and Dell classify physical and liquid damage as customer-induced damage outside the standard warranty. Accidental damage plans sold at purchase are the exception, and those usually carry a service fee.
If the repair costs less than about half of what an equivalent replacement would cost, and the laptop was doing its job before the accident, repair it. If the accident damaged the board on a machine that was already slow, put the money toward a replacement and recover the data from the old drive.
Yes. Bring it to 75 N Bridge St in Somerville as soon as you can, powered off. I open it, clean the board and connectors, assess corrosion, replace the keyboard or other damaged parts, and recover your data if the machine isn't worth fixing. The $75 diagnostic is credited toward the repair.
Spills corrode, cracks spread and loose hinges tear. Every one of these repairs is cheaper on day one than on day ten.
