ThinkPad kayboard row not working properly after water spill

I have Lenovo ThinkPad X1 Extreme Gen 2 that I spilled some water on last week. I waited a few days then tested it out and found that the keyboard was typing q1 w2 e3 r4 instead of q w e r for the entire row and a few more keys are also not working.

I tested with an external keyboard and it worked fine so I thought I would only need to replace the keyboard. Now the new keyboard is also having similar issues, although fewer keys are affected.

I uninstalled the driver and tested on both Windows and Ubuntu (dual boot) to verify that it's not a software problem.

Here's the keys not working on the new keyboard: q w e r t u y i p 1 2 3 4 5 6 7 8 0 turn into q1 w2 e3 so on. The column 9 o l . doesn't work at all.

Hi @uzebek

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 which may leave conductive residues 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

Usually with keyboards if you try to repair them you can create more problems than what you started with, so it is better to replace it.

Hopefully after you have cleaned it all thoroughly and replaced the keyboard the laptop might possibly work correctly again.

Here is the hardware maintenance manual for the laptop that will help. Go to the bottom of p.83 to view the procedure to remove the keyboard.

Here's the parts list for the laptop that will also help to find the correct replacement keyboard.

Click on Select Commodity > C-cover with keyboard (72) to find the part numbers for the 72 keyboards available for the laptop as they are country specific so depending on your location you will need to search through the list to find the correct part number. The country code is shown in the part name e.g. TUR = Turkey, THAI = Thailand, FRA = France etc. Usually the part number can be found on a sticker on the underside of the part if you wish to verify that you're getting the same one. Search online using the part number only to find suppliers 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.
