It is unacceptable for a company like Microsoft.
A serious company sends a defect report to its customers and then determines the maximum period for replacement.
The Covid period has led to many video conferences that heat up the laptop more and this has accentuated the problem.
Spending almost 2000 euros for a PC that after 4 years, for a problem declared irreparable by the manufacturer, must be replaced is not a serious company. And asking for 600 euros for repair is a theft. With all the emails that send advertising, one would have been enough to report the problem. Common sense zero and never again Microsoft PC.
