Laptops and water go badly together, and in Portobello we see more of it than in most parts of Edinburgh. A promenade coffee that gets knocked over, a glass of water beside the sofa in a Bath Street tenement, an unattended pint on a Kings Road balcony, kids running in from the beach with wet swimsuits — the surface area for spills near a laptop is much bigger than people realise. The first hour after it happens matters more than almost anything else.
The single most important thing to say up front is this: the goal is to save your data, not the laptop. Modern laptops that have taken a real soaking rarely come fully back to their original selves, and every attempt to prove otherwise usually makes the drive harder to recover from later. Slow down, don't panic, and read the next few sections before you touch the machine again.
The First Hour Is What Matters
Liquid on the outside of a keyboard is a mostly cosmetic problem. Liquid that has reached the mainboard is a chemistry problem. From the moment the spill happens, corrosion is the enemy — not the water itself. Water on a powered board starts short-circuiting things immediately; even a "dried out" board is still corroding underneath if there's residue between components. Anything you do in the first hour is really about stopping that corrosion clock as fast as possible.
That means two priorities in this order: cut the power, then get the machine into a position where liquid can drain out rather than deeper in. Everything else — insurance, backup plans, whether to try the "rice trick" — can wait an hour without changing the outcome. Those first two actions genuinely can.
What NOT to Do
The interventions that feel like the obvious thing to try are usually the ones that cause the most permanent damage. In roughly the order of how often we see them:
- Do not power the machine on to "see if it still works". Every second it's powered on with wet contacts is another second of live corrosion and short-circuits eating the board. If the spill has already made it inside, powering on will usually be what turns a recoverable machine into a non-recoverable one.
- Do not put it in a bag of rice. Rice pulls surface moisture out of open air; it doesn't reach the water trapped under a soldered chip. Meanwhile the days you're leaving it in the bag are days the corrosion is quietly progressing. It's a myth that's outlived its usefulness.
- Do not blow it with a hair dryer. Warm air pushes liquid further into the machine and drives residue deeper into the board. Compressed air is the same story on a smaller scale.
- Do not tilt it upside-down and shake it. You will move the water from where it's already sitting to somewhere new that wasn't wet before.
- Do not disassemble it if you've never opened a laptop before. Modern chassis are held together with hidden clips and fragile ribbon cables — turning a water problem into a broken-connector problem is not the trade you want to make.
What to Do Right Now
Unplug the charger and hold the power button down for at least ten seconds to force a hard shutdown, even if the screen was already off. If the battery is removable — mostly older or business models — take it out. On sealed laptops, don't try to force the back panel; leave the battery where it is and rely on the hard shutdown.
Then stand the laptop on its side in a tent shape (screen open, roughly 90 degrees, keyboard facing sideways) on top of a folded towel. Gravity does more useful work than any other single thing in the first hour. Put it somewhere at normal room temperature — not next to a radiator, not on a windowsill in direct sun — and leave it alone. Give us a call from another device and describe what was spilled, when it happened, and what the machine was doing at the time. The type of liquid changes what we plan for: sugary drinks and salt water are much worse than clean tap water because they leave conductive residue behind.
What Actually Happens on the Bench
When a water-damaged laptop reaches our workshop we always look inside first, before we ever try to power it. The board comes out, sits under a microscope, and we look specifically for the tell-tale signs — the whitish or greenish crust of corrosion around the power delivery components, discolouration near the USB-C or MagSafe connector, dulled solder joints under the RAM or CPU. If there's clear corrosion, powering up is off the table until it's cleaned.
Cleaning is usually an ultrasonic bath in isopropyl alcohol, with the board fully disassembled and shielding removed. That gets residue out of the millimetre gaps where hand-cleaning can't reach. Only after the board has dried do we test-power it, and even then only on a bench supply with current limits set so we can spot a short-circuit before it does more damage. Between roughly a third and half of the boards we treat this way come back to life for at least long enough to pull the data off cleanly, which is the whole point.
Modern Laptops Have Changed the Rules
Ten years ago, water damage almost always meant "get the drive out, put it in another machine, copy the files off". That workflow still works on most business ThinkPads, older Dells and any laptop with a removable 2.5-inch SATA drive or an M.2 NVMe stick — one of the reasons we quietly prefer those machines for people who care about their data.
On modern MacBooks (M1, M2, M3), a lot of Dell XPS and HP Envy models, and most ultra-thin ultrabooks, the NAND flash memory is soldered directly to the mainboard. There is no drive to remove. If the board is dead, the storage is dead as far as normal recovery goes — and this is where specialist data recovery becomes the only route left. It also means the machine you're carrying is more fragile than the one you had five years ago, so the "just try booting it" instinct is more dangerous than ever.
When Microsoldering Is the Only Route Left
For soldered-NAND machines that are truly beyond saving as a working laptop, the last option is chip-off recovery. That means desoldering the flash chips from the dead board with hot air, cleaning them, and reading them on a specialist programmer to reconstruct the filesystem. It's the same discipline as the phone-forensics side of things and it lives under our microsoldering service.
It is genuinely slower and more involved than a normal drive-swap recovery, but for family photos, business records or dissertation drafts that only ever existed on that one machine, it is often the difference between "gone" and "back". We always give an honest read on the odds up front, based on what the corrosion looked like when we opened the machine — no surprises later.
A Recent Portobello Story
Earlier this spring a customer working from home on Marlborough Street rang after her toddler knocked a glass of water across the kitchen table onto her three-year-old ultrabook. She had done exactly the thing everybody does — wrapped it in a tea towel, put it in a Tupperware of rice for a day, and then tried to boot it. It came on for around thirty seconds, showed the login screen, then died. She rang us the next morning.
When we opened it we could already see the pattern under the microscope: a fine green corrosion halo around the power delivery chips, exactly where the residual current had eaten the traces. The board was gone. But the NAND itself — soldered onto that same board — was physically undamaged. A chip-off session got us five years of family photos, a wedding video and a full folder of school-run drawings back, essentially intact. The laptop repair itself was uneconomic; the recovery was worth every minute.
Setting Up a Backup Before It Happens Again
Water damage is a recurring lesson in why relying on one copy of anything important is a bad idea. A basic three-copy setup solves this problem for everybody: the original on the laptop, an automatic cloud backup (OneDrive, iCloud or Google Drive, whichever fits how you already work), and an occasional copy to an external SSD that lives somewhere the laptop doesn't. If any one of the three fails, the other two are still there. If the spill also takes out the laptop's screen, at least you're only replacing hardware in our screen replacement workflow, not chasing years of lost files.
The cloud copy is the one that matters most for spills. It's automatic, off-site, and doesn't care what happened to your keyboard. If you've been meaning to turn it on and haven't, doing it this week is the single best insurance you can buy against the next accident — in Portobello, in Joppa, in Musselburgh, or anywhere else a glass of water has ever been within arm's length of a laptop.
Need Data Recovery in Portobello?
If you've had a spill and you're not sure what to do next, don't power the machine on again. Ring us, describe what happened, and we'll talk through the best next step. For Portobello, Joppa, Duddingston, Craigentinny and the wider east side of Edinburgh we can usually collect the same day if the call comes in before the afternoon. Book a recovery online or send a quick message and we'll take it from there.
