So i bought yesterday a Core Book X 14,1" 2K I3-1220P 16GB/512GB with Windows 11 Home, i have noticed that the sound only comes out from the right speaker, and the sound is low and strange. Seems like under water or in tunnel.
IF you live in EU you can repair it in the German center, if not must be in Hong Kong
IF you bought in ALI, Aliexpress have many warehouses over the world. You can ask the store maybe you dont need to send to HK
Because other than that..maybe go to a repair store and ask if they can repair it. IF its not much write to Aliexpress and ask if they would pay half of the repair. Sometimes we have some flexibility.
