hi, do you work on xiaomi mi notebook laptops? there is a swell on the body. if yes how much does it cost?

Call them, I'm sure they do take them. Swelling of the body sound like a battery issue and in need of replacing. They work on lots of devices.

Why wouldn't you just call them? They are open 24 hours. It seems naive and/or lazy to ask others to do this simple task for you. Earbuds out, phone down, finish your avocado toast and do something constructive. You'll feel better about yourself and begin establishing a sense of personal responsibility and accomplishment!
