I am attempting to flash Libreboot to ThinkPad X200, and my computer recognizes my Raspberry Pi Pico. But when I connect my Pico to the SOIC-16 chip of my X200, Pico disconnects.
I run ```sudo dmesg -wH```, connect my Pico to my X200, and connect my Pico to my computer, it didn't recognize; however, without Pico connected to a chip, I connect my Pico to my computer, it didn't recognize. What to to?

I assume you've flashed pico-serprog on the Pico. Anyway, you should always first connect the chip to the programmer.
Only then, connect the programmer to the host machine. The other way can damage your hardware.

It could be a short circuit somewhere. Do you get any overcurrent events in dmesg when this happens?
Double-check the pinout and wiring.

This contradicts the what you said in the very first sentence. Please clarify whether the Pico is
recognised when it is not connected to the X200.

“my X200" refers to the computer I want to flash Libreboot to.
"my computer" refers to another computer that I used to flash Libreboot.
Sincerely

I got that, but that's not what was confusing me.

Which one of these is true?
