Re: Lenovo Thinkbook 15 , WiFi issue and battery Drain Please help

Welcome to the forums.   You need to provide a lot more information.

Start with the output of lspci and of ip link
Did the WiFi work when you booted from the installation media?

Re: Lenovo Thinkbook 15 , WiFi issue and battery Drain Please help

It looks like your WiFi device, "Network controller: Realtek Semiconductor Co., Ltd. Device c82f", is supported started in the 5.2 Kernel tree.   As a sanity check, what is the output of uname -a  ?

Also, please use BBCode Code tags around program output.  If you would be so kind as to edit your post.

Re: Lenovo Thinkbook 15 , WiFi issue and battery Drain Please help

Try the non-LTS kernel.

[This article](https://www.notebookcheck.net/Lenovo-Th … 012.0.html) suggests an intel wireless/bluetooth device:

The ThinkBook 15 also has an Intel Wireless AC 9560 module onboard, which handles network connections. This module also supports Bluetooth 5.

Strange.

What further troubleshooting steps did you take?

However studied and stilted your rant, it can never hide the base and primitve emotion that inspired it.
