Lenovo also possibly sabotages SuperIO chip when the charging port breaks and pins come in contact or standard repair diagnostics is attempted[1]. Considering this is not widely spoken about, I guess this is limited to lower end models available only in developing regions of the world(which makes it altogether more sinister if done on purpose).

- 05 5y agoI would take the video with a grain of salt - the guy says himself he doesn’t have the schematic, there might very well be an inline ESD protection IC connected to the pin..
- Abishek_Muthian 5y agoBut he demonstrates on camera, the pin from charging port leads directly to the SuperIO pin without any protections in between? Besides there are several accounts of this on the comments of that video with similar Lenovo models. Sorin's viewership base in majority comprises of laptop repair technicians and he's quite respected in the community(Like Louis Rossmann).
