Spilled water, trackpad malfunctioning?

I spilled a slight bit of water on my personal chromebook in the school cafeteria like a goof, then i looked for paper towels which were across the room, and by the time i came back everything was still fine except the trackpad. I cleaned everything off and everything was working fine, but the trackpad was still acting silly so I let it dry off for a couple of days. I came back to it, now my trackpad detects movement, but doesn't detect pressing. This isnt that much of an issue because I have a mouse and touchscreen, but it's so tedious when I accidentally touch it and now touchscreen doesnt work neither does my mouse. Any help?

Hi @coffeesandtea

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 the maintenance and service manual for the laptop that will help. Go to p.26 to view the procedure to access the touchpad so that the cable conection can be checked and cleaned. If the touchpad is faulty, search online for L14356-001 to find suppliers of the part that suit you best.

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.
