Thinkpad S1 Yoga stopped charging with a 45W adapter

Hello

 

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

Hi Chaitanya,

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.

Please feel free to post in Lenovo Community Forums if you have any further queries!

 

Regards,
Prabhansh

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
