For Badcaps Readers, Please note that I am hopefully going to present this same message to Lenovo to see if they have any insight to the matter as well and figured to share the entirety here for clarification. The System is out of warranty as it is but does have the option to have it extended.

Hi,
I want to remove the Bios Password of my Lenovo IdeaPad U330p with the Lenovo autopatcher. I have the CH341A Black and I'm using NeoProgrammer.
