Question did you have to go through a Jtag to read the EC information? or was it through the keyboard?

some EC can be read from the keyboard connector on the motherboard. But since it is a Lenovo thinkPad computer I’m assuming you has to use the Jtags connections and might have had to move a 10k to a different t place to be able to read the EC.
