Hello technicians,

I am trying to read the EC MEC1663-BA0 of a ThinkPad X1 Yoga Gen5, board NM-C881. I can access the BIOS, but it is not possible to change some options. I have an SVOD programmer and it supports the EC. Unfortunately, I don't know which pins on the keyboard connector are:
TDO
TCK
TMS
TDI
I have read that the EC should have two areas.
Does anyone have specific experience reading the EC with an SVOD programmer and which areas to read?

I have a Lenovo L15 Gen 1. The touchpad and trackpoint on the device are not working. Not even in BIOS, so it's not a driver issue. The touchpad is enabled in BIOS. When I run Lenovo Diagnostics for Windows, the touchpad is not even recognized. I have already updated BIOS, without success. VCC is present on the touchpad connector.
Does anyone have any ideas?
Thanks
