Recently I've bought Lenovo Legion 7 laptop for work. I thought it would be great to highlight setup steps and potential issues with Lenovo Legion 7 laptop. I do it mostly for myself to remember how I did it.
My version has the following configuration: LENOVO Legion 7 15IMH05, 15.6", IPS, Intel Core i7 10750H 2.6GHz, 16GB, 512GB SSD, NVIDIA GeForce RTX 2070 MAX Q - 8192 Mb, Windows 10, 81YT0017RU. I bought it with a rather good $350 discount.
Please, be careful with laptop configuration and do everything at your own risk. I cannot guarantee that things worked for me will work for you.
- The first issue that I faced with was that when you just plug-in HDMI cable (without even plugging in the other end of it), Wi-Fi stops working. It happens when Wi-Fi frequency is at 5GHz. That it's not only a Windows issue, but Ubuntu Linux also has the same problem.
There are several ways advised to solve this issue:
- buy a better-isolated HDMI cable. I finally bought a HAMA Premium GOLD HDMI v2.0 1.5-meter cable and it seems to solve the issue for me!
- rollback WLAN driver to an older version shipped with Windows (not the one that is provided by Lenovo). The older driver worked for me for a while, but then I did some manipulations and this approach stopped working for me for some reason.
- switch Wi-Fi frequency to 2.4GHz. I did it both in Windows and in Ubuntu Linux and for now, I live with this solution. In Windows, it's done in driver settings (from Device Manager). In Ubuntu, it can be done by running
nm-connection-editorin the command line.
- In any Linux distribution, there will be no sound from speakers due to this bug. Note, that you'll have the sound if you plug in headphones.
- Ubuntu will not install when RST is enabled in BIOS, but if you turn it off, Windows will stop loading.
I followed this guide, but it didn't really work well for me. Windows was not loading and commands from the guide didn't work (some paths were different, etc). If I remember correctly, I loaded the command line in repair mode and ran
bcdedit /set safeboot minimalthen I loaded into the operating system in safe mode, and then I executed
bcdedit /deletevalue safeboot
I guess loading in safe mode helped to fix storage drivers.
- Also, I decided to turn off Secure Boot when installing Ubuntu to avoid all the hustle with drivers signing.
- Another minor issue that I've noticed is a quiet noise from a laptop charger. You will barely spot it during the day. But you might hear it if you are in a quiet room at night. As far as I read on the Internet, it is not considered an issue and should be harmless (at least, I hope so).
