MacBook Water Damage Repair; Liquid Spills, Corrosion & No-Power

We fix spill damage the right way: component-level logic board repair, ultrasonic cleaning, and replacement of liquid-damaged parts. Free estimate, no pressure, no data / no fix = no charge. Visit our Austin lab or use our nationwide mail-in service.

MacBook liquid damage repair; mail it in or come to our store

You poured water, juice, or beer into your laptop. Don't panic; this is what we fix for a living. You'll receive an assessment of exactly what the spill damaged and what needs to be repaired at no charge. If it's not worth fixing, you can take it back at no cost. If you're local, stop by our Austin store. If you're not, mail your MacBook in for a free estimate.

Spill damage corrodes sensitive components; but it's not unfixable. At Apple, you'll often hear $750-$1600 flat-rate quotes to replace the entire board. That's a board swap. We prefer engineering: repair usable parts you already own and restore functionality at a fair price.

Important: if liquid gets inside, stop using the MacBook immediately. Powering it on lets electricity flow through wet, shorted components and makes corrosion worse. Minimizing damage early increases the chance of a fast, affordable repair.

When you come to Rossmann's, we fix it

What sets Rossmann Repair Group apart? Many shops outsource board repair because they don't have the tools or experience. That causes delays, surprises, and a game of telephone between you and a third-party lab.

With us, the buck stops here. We repair your MacBook and its logic board in-house. We've taught thousands of technicians via free YouTube content, guides and personal instruction.

Problems we fix on liquid-damaged MacBooks

  • • Not turning on
  • • Freezing / random shutdowns
  • • No light or image on the screen
  • • Not charging the battery
  • • Keys not working properly
  • • Trackpad not working properly

How we repair spill damage

  • • Component-level logic board repair (no unnecessary board swaps)
  • • Repair what's broken to save cost and time
  • • Ultrasonic cleaning of corroded components (far beyond the "alcohol & toothbrush" myth)
  • • 90-day warranty on our work

Watch: Liquid damage in real time (microscope)

This clip starts exactly where corrosion becomes visible (03:06). You'll see bubbles and "paths" form as electricity flows through moisture on the logic board; and how the reaction stops the moment power is cut. This is why we say: after a spill, power it off.

What the on-screen numbers mean

  • Upper-left: PPBUS_G3H; the main power rail on MacBook logic boards. It should sit around 12.56-12.6 V. When water hits, you'll see it jump toward ~17 V and then sag; clear evidence the circuit isn't regulating normally. Sending 17 volts to things that expect 12 volts ends bad!
  • Bubbles / movement: that's an electrochemical reaction actively corroding components. When power is cut, the bubbles stop because the reaction stops.
  • • Voltage shouldn't swing like this; moisture creates shorts and backfeed.
  • • Re-powering while wet accelerates damage and raises repair cost/time.
  • • Powering off immediately limits corrosion and improves repair outcomes.

Before & after

After: cleaned and repaired MacBook board

At the time of photographing, that board alone cost ~$750 as a part. We repaired it for $325; and it's still alive & kicking.

Typical repair pricing

Pricing depends on model and the extent of corrosion/part damage. Here's a realistic range based on thousands of successful repairs:

Keyboard
$175-$350 (model dependent)
Trackpad
$125-$250 (model dependent)
Logic Board Repair
$250-$425 (most); rare/newer cases up to ~$600 when donor boards are required
Board + Keyboard + Trackpad
$300-$600 (model dependent)

Frequently asked questions

Can a MacBook with water damage be repaired?

Yes. Most spill-damaged boards can be restored with proper cleaning and component-level repair. The sooner it’s powered off and dried (don’t keep trying to turn it on), the better your odds.

Does Apple cover water damage?

Liquid damage is not covered under standard Apple warranties. Apple often quotes high flat-rate board replacements. We repair at the component level, which is usually more affordable.

How much does liquid damage repair cost?

It depends on what the liquid damaged. Typical ranges: keyboard $175-$350, trackpad $125-$250, logic board repair $250-$425 (rare cases up to ~$600 when donor parts are required).

Will my MacBook Air work after spilled water?

Usually, yes, after proper cleaning and repair. Do not keep turning it on; that spreads damage. Bring it in or mail it to our lab for a free estimate.
