Can water cause the black screen of death?

Water damage is one of the most common causes of electronics failure. If water gets inside your computer, smartphone, tablet, or other electronic device, it can cause all kinds of problems – including the dreaded black screen of death. But can a bit of water really brick your device that quickly? Let’s take a closer look at how water causes damage, when you’re most at risk, and how to recover from a water-related black screen of death.

What causes the black screen of death?

The black screen of death, commonly abbreviated as BSOD, refers to when your computer suddenly crashes and displays a black screen. This is different from your display simply powering off – with a BSOD, the computer is still running but has encountered a critical error that prevents the operating system from functioning properly. Some common causes of the BSOD include:

Hardware failure – Faulty RAM, hard drive issues, graphics card problems, etc can cause a BSOD.

Driver conflicts – When two drivers compete for the same resource, it can crash the OS.
Software issues – Bugs, malware, viruses, and incompatible programs are common software-related causes.
Heat – Excessive heat leading to thermal throttling or shutdown can sometimes cause a BSOD.

As you can see, there are many potential causes. But when water or liquid damage is the culprit, it’s usually due to short circuiting of the components on the motherboard and corrosion over time. To understand exactly how water causes these issues, let’s break it down.

How does water damage electronics?

Water is very conductive and carries minerals that can quickly corrode metal components. Here are some of the main ways water can damage electronics:

Short circuits – Water can bridge connections and create shorts between circuits that aren’t meant to connect. This can immediately crash a system.

Corrosion – Minerals in the water catalyze corrosion reactions on metal contacts and traces.
Mineral deposits – Minerals left behind on circuit boards after water evaporates can interfere with connections.
Oxidation – Oxygen in water causes oxidation damage over time, which can break down components.

With so many sensitive electronic components packed tightly together in modern devices, even a small amount of water in the wrong place can be devastating. Short circuits and corrosion from water damage will quickly lead to unpredictable behavior, crashes, and the dreaded black screen.

When is water damage most likely to cause BSOD?

Water damage can cause immediate or delayed BSODs, depending on where the water ends up and how it got inside your device. Here are some of the highest risk scenarios:

Powered on during spill – If your device is still running when water spills on it, a BSOD is very likely.

Water on motherboard – Direct contact with the components is worse than just the case/shell.
Full submersion – Complete submersion greatly raises the risk of shorts.
Sugary/salty liquids – Contaminants exacerbate corrosion and mineral deposits.

High-voltage components – Areas near the CPU, RAM, etc are most vulnerable.

If the spill only impacted the outer case and external components, you may avoid an immediate BSOD. But if water reached the motherboard or got on components with power running through them, the odds of crashing skyrocket. Treatment and cleaning right away improves your chances for recovery.

How to recover from a water-related BSOD

If your device exhibits a BSOD or other odd behavior after getting wet, don’t panic. Here are some steps to give yourself the best shot at recovery:

Immediately power off – Don’t try to restart or force shutdown. Simply remove power sources and let it dry.
Drain out water – Carefully drain any standing water by tilting the device. Absorb remaining moisture with a microfiber cloth.
Disassemble – Take the device apart to the extent you’re comfortable. This gives interior parts the air exposure needed to dry out.

Dry components – Use compressed air to blow remaining droplets off boards and connectors. Give it at least 24-48 hours to air dry before reconnecting power.
Check for damage – Inspect components for corrosion, minerals, oxidation, etc. Replace parts as needed.
Reassemble and test – Once fully dry, put it back together and see if it works. You may need to replace damaged hardware.

The quicker you can power down, disassemble, and dry out the device, the better chance you have of reviving it and avoiding permanent damage. But if significant corrosion has already occurred, you may need to replace the motherboard or other components.

Best practices to avoid water damage BSODs

While you can’t prevent every spill, there are some best practices to help avoid or minimize water damage:

Keep drinks away from electronics.

Use water resistant cases or bags when taking devices near water.
Shut down and unplug devices before exposing them to spills or storms.
Never charge electronics near water sources that could leak, splash, or condense.

Position devices away from sinks, sprinklers, pools, etc.
Handle water damaged devices properly – power off, dry out, inspect, replace parts.

Being cautious around liquids and acting quickly after a spill gives you the best shot at avoiding the dreaded black screen of death. But even if you take all the right precautions, freak accidents can still happen.

Can rice help dry out a wet phone or laptop?

You may have heard that submerging your wet electronics in rice can help absorb moisture. Here’s the truth on using rice to dry out water damaged devices:

It helps remove liquid water – Rice can wick away droplets of water from the surface and air pockets between grains provide airflow.
It doesn’t remove moisture well – Rice isn’t very effective at drawing water out from inside components or underneath ICs.

It’s slow – Air drying is faster. Rice takes 1-3 days to dry out devices while air drying only takes 24-48 hours.
It leaves residue – Grains of rice can get stuck and leave material behind in small crevices.

So while rice can provide some benefit, it’s generally better to disassemble devices and use compressed air to properly dry out the interior. Don’t rely solely on rice to revive a wet phone, laptop, or other electronics.

Does water damage always result in a BSOD?

While liquid spills greatly raise the risk of immediate or eventual BSODs and hardware damage, they don’t guarantee it. Here are some cases where water may not cause a black screen of death:

Very small spills on the outer case/sealant.
Powered down devices that are quickly dried out.

Water that evaporates before reaching interior components.
Pure water with low mineral content.
Short exposure times before thorough drying.

For example, a few drops of water on your phone while turned off may not cause any issues if wiped off and dried properly. But again, directly contacting the motherboard or other vital components makes BSODs extremely likely. It’s best to avoid water around electronics entirely when possible.

Can condensation cause BSODs like liquid water?

Condensation can also damage electronics in some cases. Here’s how it compares to direct water exposure:

Lower volume – Usually just a thin moisture layer, not large spills.

Distilled water – No extra minerals/contaminants like tap water.
Covers larger area – Condensation can coat entire boards, versus localized spills.
Harder to see – Transparent coating, versus obvious spilled water.

So while not as immediately damaging as direct liquid water, condensation can still potentially cause shorts and corrosion over time. Electronics should not be used until all condensation has fully evaporated.

What devices are most vulnerable to water damage?

Some types of electronics are more resistant to water exposure, while others are extremely vulnerable. Here they are from most to least vulnerable:

Desktop computers – Exposed components make water spills extremely damaging.

Laptops – Small size and portability increase risk of spills.
Tablets – Less protection compared to water resistant phones.
smartphones – Water resistance is improving but still a risk.

Waterproof cameras – Designed for underwater use.
Smartwatches – More water resistance as a wearable device.

Of course, any electronic device is still vulnerable to moisture damage if exposed past its design limits. But desktops and laptops tend to be least tolerant of direct liquid exposure compared to portable devices with some waterproofing.

Should you try fixing water damaged electronics yourself?

It’s possible to revive wet devices yourself, but consider these risks before trying:

Requires disassembling down to the motherboard level in most cases.
Risk of electrocution from shorts if not fully dried.

Corroded parts may need replacement you don’t have on hand.
Incorrect reassembly can cause further damage.
May void your device’s warranty if opened up.

If you have the technical skill, proper tools, replacement parts, and understanding of the risks, repairing water damage yourself can save money. But for most average users, seeking professional data recovery is a safer choice to maximize chances of restoring your device.

When should you declare water damaged electronics dead?

Here are some signs it may be time to give up on reviving a water damaged device:

No signs of life even after thorough drying and cleaning.

Clear evidence of unrepairable physical damage from corrosion.
Cost of professional repair exceeds replacing the device.
Data has been recovered, so device functionality is no longer needed.

If you’ve made a concerted effort to revive the device both yourself and via professional service without success, it may be time to cut your losses. Though with proper care, surprising recoveries can still happen even if a device stays dead for weeks after water damage.

Can liquid damage be reversed with software or remote repair?

Unfortunately, most water damage requires physical inspection and repair. However, a few remote troubleshooting steps may help:

Updating drivers and OS in case of software issues.

Using remote access to attempt data backup and recovery.
Reinstalling the operating system as a reset.

If the hardware itself remains functional, software tools may resolve crashes and data loss issues. But they can’t reverse physical corrosion and deterioration of components caused by water. Liquid damage generally requires hands-on disassembly and repair for full recovery.

Conclusion

Water and electronics don’t mix well. Spills can clearly lead to black screen crashes and full device failure in many cases. Quick action is required to maximize your chances of reversing the damage. Air drying, full disassembly, component replacement, and professional data recovery are your best options when facing a water damaged BSOD situation. With proper care, even seemingly dire scenarios can sometimes be repaired. But prevention is most effective whenever possible by keeping liquids far away from your expensive electronics.
