Laptop won’t turn on after water spill.

A friend of mine accidentally dropped his water bottle into the pocket of my messenger bag where my laptop was sitting in. The laptop was in its own bag, but I only noticed that the water bottle was in my bag after 5 minutes or so. I took it out of the case and wiped the water off with a tissue paper, I turned it on and it was working quite well despite the slowness of my browser. After an hour, I closed the laptop and to go attend to some errands, after another 5 minutes, I plugged in my laptop to start working again, I booted it up and it while I was working it froze, so I shut it off and plugged it into a power source, then it stopped turning on. I then noticed that there was still some water on the power button. It’s been another hour and it still hasn’t turned on, any info that could help?

First, remove the power (unplug and pull the battery if possible)

Likely there is still water in it, if the button is wet. You will need to dry it out. Getting some desiccant, and putting the laptop with it, and while making there is room for some airflow and letting it dry out; it may take a few days.

Using some rice would work, as it is good to absorb moisture (put the laptop in something like a cotton pillow case, to keep the rice separate)

Sadly, the longer the time between when it gets wet and when it is dried, it can allow oxidization and corrosion of the components and is a chance that it will not work.

Hi @wolphin

This link may be of interest to you

Rice is for dinner, not repair

The best way is to open the laptop, disconnect the battery from the motherboard and clean all the affected parts with Isopropyl Alcohol 99%+

It is better than nothing... especially when you are not in a place that you can get anything else. Opening up the item would be better, I agree. I do know people have placed camera lenses in a bag then into the rice, in a 3rd world country where actual descant is not available.

Hi @othniel ,

The impurities in the water causes corrosion and provides circuit paths for the electricity which were not in the laptop’s operating design and could damage the components. The corrosion starts immediately and is ongoing until it is completely cleaned away

First do not try to charge or to turn on your laptop and then remove the battery as soon as possible from the laptop to minimize any further damage.

Then you need to dis-assemble the rest of the laptop and clean all the affected parts using Isopropyl Alcohol 99%+ (available at electronics parts stores) to remove all traces of corrosion and water. If possible do not use "rubbing alcohol" as in some cases this is only 70% IPA or less, can contain additives and is not as effective. If you do have to use it check the label to verify the amount of IPA. The higher the percentage of IPA the better

Here is a link that describes the process. Electronics Water Damage

As always with electronics, especially surface mounted pcb be gentle when handling and especially when brushing away the corrosion. You do not want to remove any components from the board. Remove the shields that may be covering some components as the water may have got in under there. The ends of any flex cables and their connectors need to be cleaned as well

Hopefully after you have done all this the laptop might possibly work correctly again.

Here is a link to the hardware maintenance manual for the laptop which will help you with dis-assembly etc

If this process seems too daunting, take your laptop to a reputable, professional laptop repair service, experienced in liquid damage repair and ask for a quote for a repair. If you decide to do this, do it sooner than later.
