Two days ago I bought a laptop in your store and everything was in check with him.
But, on arrival, I found out that the operating system cannot be loaded without fatal errors.
I measured the voltage coming to the CPU and found that the third pin on it receives 4.5 volts instead of the set ones 9.
The synchronous frequency converter also apparently does not work correctly.
This shows in its turn about the obvious malfunction in the power supply unit of the motherboard.
Accordingly, this is a hardware error, and in no case is not a software error, as your employees convince me.
In connection with the above, I ask you to replace the computer I previously purchased, or to return paid money.
In case of failure to fulfill my requirements, I will be compelled to file a suit with the court.
