Hello. I bought the laptop 1,5 months ago.

When I connected the charger, the laptop began to get very hot and the fan hummed a lot. I installed the latest versions of all drivers, but it didn't help.
When I write code without a charger, the laptop is quiet and cold, but when I charge it, it starts to warm up and make noise.

Hello @granit1986 .
Do you have updated the bios of your equipment?
Is the inside of the equipment clean?
Have you serviced the fan?
Have you already changed the thermal paste to a high conductivity one?

Hello.

Yes, I installed the latest BIOS version.

This is a new laptop and no maintenance has been done yet.

Thank you for checking and commenting.

 

Power draining is suitable for a hardware restart or hard reset to be performed, and this does not erase personal information.
Many boot errors and other problems can be solved by decreasing the accumulated energy in the hardware components. This procedure of reducing stored energy is also known as a hard reset.
o Turn off the computer.
o Disconnect the computer from any port replicators or docking stations.
o Disconnect all peripheral devices, such as USB storage devices, external displays, or printers.
o Disconnect the AC adapter from the computer.
o Turn the computer over and look for the battery compartment door to determine whether or not your computer's battery is removable.
o Now to consume any residual electrical charge from the capacitors protecting the memory, perform the following as it is the basics of this:
If you see an access door to the battery compartment, your equipment has a removable battery. Remove the battery, press and hold the power button for 15 seconds, reinsert the battery back into the compartment and proceed to the next step.
If you do not see any access door to the battery compartment, your computer does not have a removable battery. On most laptops with a non-removable battery, press and hold the power button for 15 seconds to complete the restart and proceed to the next step.

1. Reconnect the AC adapter to the computer, but do not connect any peripheral devices.
2. Turn on the computer.
If a startup menu opens, use the arrow keys to select Start Windows normally and then press enter.

I did as it is written in the instructions, but nothing seems to have changed.

Sorry, my mistake. I described the situation a little incorrectly. The fan starts to make noise because the temperature of the processor starts to jump constantly from any action. I can just open a few browser tabs or open IDE and the temperature goes up to 90+ degrees Celsius.

Perform a hardware scan before Windows starts and we will be able to find out what the problem is:
