820-01041 MacBookPro 15” 2018 - not turning on,not charging

[David82827372]

Hello, can you assist in identifying the issue and providing repair steps? authorised by apple service centres in my country don’t have best reputation and I need opinion from someone who faced something like this.

Water entered the connection between the screen and keyboard of my MacBook Pro. The power button has stopped functioning. I had to use the charger to turn on the MacBook, but now it’s not working anymore. MacBookPro doesn’t charge and I can’t turn it on.

Additionally, i saw in the battery settings, a message "service required" .

Hi and welcome to this forum. We had an initial chat at macrumors.

Do you have access to tools for the MacBook in your region? Like screwdriver sets, multimeter, etc? If not, perhaps Amazon delivers to your area?

Yes,I could buy it here,but I'm not a tech person,so I might break my Mac totally.

I think your options are limited. With liquid damage, there is always the risk that the CPU has been damaged due to the liquid travelling across higher than normal power rails. At the very least, the case needs to be removed -> logic board inspected after the battery is removed so there is no further damage. Then often, cotton swap / Q-tip with alcohol is used to clean up where the liquid can be seen. Then test again. The additional tools are required to study the power rails, etc. which may lead to soldering required to fix the fault(s). If you have a local friendly tech, perhaps consider to lean on them for help.

You must have a local cell phone tech that will be comfortable with such rework? Perhaps at a local mall? Do check around if they are ok with logic board repairs.

Thank you for such detailed instructions.
All Apple services I found in my location don't do such a complicated work as you described. They just replace everything that might cause problems : keyboard,battery.

I think your better options are to contact local cell phone repair shops. I recall on my assorted travels that some of the smallest shops in malls are doing amazing work at the component level. Was very impressed. Do give this a try. Many are comfortable with other repairs like yours. Ask them if they have macbook tools (torx, etc.) and they should to at least review the logic board with the liquid spill.
