Hi Aliaksandr F,
Thank you for reaching Microsoft Community. We're sorry for the inconvenience this has caused you.
I am aware of how frustrating it may be to have a device that gets warm when in use. I am here to help.
If a Windows application or service uses lots of CPU resources for an extended period, the processor will get warm. That is expected and normal, regardless of what brand of computer you're using. You can determine this by looking at task manager in the CPU column (sort by) to see if particular application is consuming the CPU.
- Close all the apps that you are not using.
You may perform the following steps to troubleshoot your device.
Force the device to shut down and restart.
Press and hold down the power button until your Surface shuts down and restarts and you see the Windows logo screen (about 20 seconds), then release the power button.
Run Surface Diagnostic Toolkitand check Windows updates including optional updates if available.
See: Fix common Surface problems using the Surface Diagnostic Toolkit (microsoft.com).
To check for updates: Go to Settings>> Windows updates >> Check for updates.
Update drivers and firmware
Check what is the current OS Build of your Windows version. On the search box type Winver and hit the enter key. Go to Download driver and firmware for Surface, choose Surface Go. Then click the link next to Surface Go 2 then click Download on the next page. Choose the .msi file that matches your current OS Build and click Next. After downloading, run and install the .msi then Restart.
- Set up your device on a stable work surface that allows for adequate air circulation under and around it.
- Use caution when operating your device on a pillow, blanket, or other soft material, because the material can block the airflow, and this may cause device overheating.
- If the device is being used in a warm environment or in the sun, move device to cooler environment.
Surface devices adhere to all laws and guidelines related to temperature and thermal. It complies with the user-accessible surface temperature limits defined by the International Standards for Safety (IEC 60950-1 and IEC 62368). See Product safety warnings and instructions - Microsoft Support refer to sections called “Heat related concerns” and “Heat related concerns for wearable devices”.
