When I connect the internet connection then laptop automatically shutd

However I will answer this question considering the laptop as a usual Lenovo laptop. The following are some possible causes that could have been happening👇

1. Check for malware or some other unwanted stuff

# Malware are a notorious one, they can cause a variety of issues, including your laptop to shutdown when connecting to the internet. Consider running a malware scan on your laptop.

1. Try to boot in safe mode with networking (F5)

# Press the left shift button and then press restart and don't leave the shift button until you see the laptop restarted. Then go to Troubleshoot -> Advanced options -> Startup settings -> Restart -> Just press F5 once a blue screen appears after another restart. Connect your laptop to ethernet and check if it shutdowns. If yes, this indicates a deeper problem.

# Just Update your drivers

# Outdated drivers can sometimes cause issues with internet connectivity. Try checking that all your drivers are up to date, especially the network drivers.

1. Troubleshoot network adapters

# Try to troubleshoot your network adapter by going to Start -> Settings -> Update & Security -> Troubleshoot -> Network adapters -> Run the troubleshooter

1. Perform a clean boot (You need to be the administrator of the laptop)

# A clean boot disables all non-Microsoft related apps and services (3-party apps), but for this purpose you need to be the administrator of the computer. You can then identify that its a malware or something or it is just the hardware.

1. 🎗️RESET🎗️

# The most recommended as usual, this thing makes your computer a brand new one. Your compute becomes fast and Un laggy, along with fixing all the problems. I would recommend to not restore everything but to manually install apps by yourself, this way you don't download the previous unnecessary apps and you only download app that you need and is in your head, which is actually good. Have a backup and restore only for photo's and videos and for account, passwords. They are necessary and are not possible to bring back in any way without a specific backup for each.
