Calling authorized service centers showed a shortage of parts in Russia. Especially hard to find a keyboard. Hence, Huawei reported that there are only two keyboards available for the Huawei MateBook X Pro 2020 at all the company’s service centers in the country. And spare parts for Acer are waiting for 2-4 weeks. The same goes for other brands.
As for Apple, the repair situation is better, but the supply of parts for laptops is also delayed. But in “NB Service” they said they had repairs stuck due to lack of spare parts.
At the same time, there is no shortage of spare parts in unauthorized service centers. Most likely, experts use non-original components. Authorized centers also have the option to use parts from other laptops.
In other cases, you can safely place parts from used laptops.
