Trackpad touch and left button doesnt work after small water spill.

Yesterday, I spilled less than a teaspoon of water on my 15-ba054sa's trackpad and now the tap on the trackpad, and the left click button are out of use. I've tried using a hair dryer on low heat, and keeping my laptop upside down over night. Everything else on the laptop works normally aside from the left click and the trackpad hand motions, and tap. What can I do to try and fix this?

Update (04/14/2018)

I've cleaned it up, and it's been about 2 days since the initial spill. The trackpad left click button works sometimes, and the right one has worked perfectly fine as it initially did. Sometimes, the trackpad left click will work on its own as if it has been clicked and dragged as I use my mouse. What should I do now? Do I wait to see if it works later on, or not?

Answer this question I have this problem too

Is this a good question?

Hi @pupathaniel ,

As you know water and electronics and electricity are not a good mix.

The water causes corrosion and provides circuit paths for the electricity which were not in the laptop's's operating design and could damage the components.

First do not turn on your laptop and then you need to, with the laptop turned off, remove the battery as soon as possible from the laptop to minimize further damage.''

Then you need to dis-assemble the rest of it and clean all the affected parts using Isopropyl Alcohol 90%+ (available at most pharmacies) to remove all traces of corrosion and water. Do not use "rubbing alcohol" as in some cases this is only 70% or less, can contain scents and is not as effective. If you do check the label to verify the amount of IPA

Here is a link that describes the process.

Electronics Water Damage

As always with electronics, especially surface mounted PCBs be gentle when handling and especially when brushing away the corrosion. You do not want to remove any components from the board.

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

Here is a link to the service manual for your laptop, taken from this HP webpage .

Scroll to p.62 to view the necessary pre-requisite steps and then the procedure to remove / replace the touchpad button board. If cleaning away any corrosion etc does not resolve the problem (look for damaged components near the button board as well) then perhaps the button board will have to be replaced. You'll find the part number on p.62 as well. Just search online using the part number only to find results for suppliers of the part.

If the touchpad also doesn't work after cleaning etc., (don't forget to unplug the keyboard / touchpad cable and clean the connectors) and there are no other components obviously affected or damaged then the touchpad may also have to be replaced. The touchpad is part of the keyboard assembly so you'll have to order a new keyboard. See the manual for the keyboard part number appropriate to your model laptop.

If this process seems too daunting, take your device 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.

Hopefully this is of some help.

Hi @pupathaniel ,

It sounds as if there is a problem with the left button contacts intermittently going s/c. (appearing to operate) Whether or not it will improve I cannot say. Time will tell one way or the other.

Have you also cleaned the ends of the cables that connect to the button board, just in case the water seeped into the cable connectors and started a problem there? You'll have to disconnect the cable from the button board to do this. Don't forget to check the cable connector on the board as well for any corrosion etc.

I assume that you used IPA or similar to clean the rest of the button board etc.

If the problem is still there it may be that the actual button contacts are the problem and most probably the only way to resolve it is to replace the button board.

See the answer I gave earlier on how to do this.

Hi @Sayednowroz Sayedy,

Here's a link to the service manualfor your laptop.

Scroll to p.42 to view the necessary pre-requisite steps and then the procedure to remove the palmrest assembly.

The touchpad is part of the assembly.

Once you have access check for water damage etc and follow the information in the above answer about how to try to fix it.

If you can't fix the water damage to the touchpad, you may have to replace it.

I had this same problem; I actually touched the touchpad with slightly wet hands and it stopped working. I spread the slightest bit of baby oil/oily cream, weird as it sounds, just on the touchpad and then wiped with a towel, and this has completely worked for me. Hoping I could be of help to anyone.

It took from Thursday afternoon till Saturday afternoon, but it’s working. And it really wasn’t that much — it was HOT coffee and probably a tablespoon, but every drop on the touch pad. I did turn it off and on during the 48 hours. Checking. Had kinda given up. I set it up like a camping tent and a couple of times a day used my blow dryer on low — and swirled it around inside and on the backside where the vents are. At night, it was next to my ceramic space heater. I also gave it belly rubs a couple of times a day, and now — all seems to be well. Something kept trying to update when I’d turn it on a couple of times, but it would hang up, so this last time as it began to “update” or spin or whatever, I just decided to walk away and leave it alone and when I came back in 10 long minutes, it was working. it is still in warranty, but I just didn’t want to deal with the COVID drama of whatever I’d need to do. So, don’t despair — belly rubs.

This was very helpful. After partially spilling some water on my trackpad from cleaning dishes, I used a few belly rubs and waited a few days and it was back to normal. Everything worked fine. I didn’t need to do any software updates but I am very glad this has worked.
