Sorry, all of the linux stuff is just specific to my own preferences/environment - if you’re more familiar with windows it would be best to just use that for testing. Presumably it will come with windows installed?

If so, put some programs on a normal usb storage device and then install/run them from there.

• For the cpu stress loading, you can use CpuStres: https://learn.microsoft.com/en-us/sysinternals/downloads/cpustres
• For temperature monitoring, you can use Open Hardware Monitor: https://openhardwaremonitor.org/
• To test the microphone/camera, I’d just use whichever app you’ll normally be using them for

As for the rest:

1. When you first turn the laptop on, at the red Lenovo splash screen, press Enter repeatedly to get into the boot menu. Once there, it’ll give you a list of options with associated keys to access them - go to “BIOS Setup - F10” (or something similar, not sure of the specifics on the X1C 6th gen). If it prompts you for a password to enter that, it’s locked.

2. To test all the ports, plug your usb stick with the apps on it into each of the usb ports and make sure it shows up in explorer; try the same with an sd card if you have one; plug in to a wired ethernet connection and make sure you have internet access through it (disable wifi at the same time to make sure); plug headphones into the jack and make sure they work; plug into an hdmi display if you have one.

3. To check battery health, run Command Prompt with administrator privileges, then run powercfg /batteryreport to generate a battery health report

Good luck!
