I own a thinkpad S1 yoga laptop (core i3 processor and 4 GB RAM).
It suddenly stopped charging using 45W adapter (20V, 2.5 A). However, it is charging fine using a 90W adapter (20V, 4.5 A) which I got with my previous Lenovo laptop
Any recent windows or system updates caused this? Is there any solution other than using a 90W adapter which I am scared to use as it may charge 47W battery too rapidly casuing a quick death of battery or explosion in the worst case. Please help

Welcome to Lenovo Community! And happy to have you here.
As I understand that you have query regarding your 45W AC Adapter is not charging your ThinkPad S1 Yoga
I believe the AC Adapter has gone bad as you have mentioned that its charging fine with 90W Adapter
I don't think so it is caused due to software or Windows updates. You can also check whether its getting charged in shutdown mode or not to confirm.
I hope the above information helped you.

The same adapter is working fine on any other device in our office. So there is absolutely no issue with the adapter. I have also tried with other 45 w adapters that my colleagues are using and nothing is working
