HELP ASAP - Lenovo 45W powerbank not working with YOGA s740 15.6

2020-07-29, 19:38 PM

I tried using the powerbank when laptop's power is at 98%,  58% and 10%  however it's not charging the laptop. I have also used the dongle both for usb-c and usb-A output but none of them works. I also have a power brick usb-c that has an output for 100W with 20v but even that isn't working even using the dongle to the power connecter that comes with the lenovo powerbank. 


2 problems:

i - lenovo 45w powerbank isn't charging the laptop although works with my mobile devices

ii - my charger that is 100w output doesn't work with the laptop using the powerbank's dongle to the power connector even it meets the requirement 20voltage.

I don't have such a Yoga and I guess I don't understand exactly how you're trying to charge the laptop...


I can't find any indication that it charges via any port other than the slim-tip charging port.  Also seems that it needs 135W.






Please clarify what port you're trying to use to charge the laptop.

The PowerBank has PD capability? If not, you will not be able to charge!
