Huawei Matebook x Pro charging light flicks on and off

Hi @aairey

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

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.

First do not turn on your laptop and then you need to open up the laptop and disconnect the battery as soon as possible 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 90%+ (available from electronic parts stores), to remove all traces of corrosion and water. Do not use "rubbing alcohol" as in some cases this is only 70% IPA or less, can contain scents and is not as effective. If you do use it, check the label to verify the amount IPA.

Here is a link that describes the process.

Electronics Water Damage

You may have to replace the battery as it is very hard to recover a battery if the water damage was severe.

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 the laptop might possibly work correctly again.

Here is a link to a video that shows how to open the laptop which may be of some help.

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.

Note:

Remove the hard drive (don’t know your laptop whether it has a SSD or HDD) and carefully dry it and keep it safe as it has all your data on it. If the laptop cannot be successfully restored at least you have your data and can retrieve it by connecting the drive to another computer. There are plenty of videos online that show how to do this.
