Ideapad s740 charging via thunderbolt 3

2019-11-18, 2:49 AM

Hi! I bought Ideapad s740 several days ago one of the main reason is it provides two thunderbolts 3 ports. I tried to charge mine using 2018 Macbook Pro 13inch wall charger but failed. Does s740 support charging via thunderbolt 3? I know it's slower than 135w charger, but usb-c will be more portable. 

 

Thanks!

Based on the Lenovo Product Specification Reference, it doesn't support USB Power Delivery.

If it does, shouldn't it be listed here?

The other thing I could think of is the Apple adapter refusing to charge anything else but Apple devices.

Hi All,

 

As mention from Lenovo web site here.

 

 

The IdeaPad S740 comes with two Thunderbolt™ 3 ports. Up to 8x quicker than USB 3.0, they are the fastest and most flexible way to hook up to displays, docks, and storage—and double as a power source, too.

 

This make's the machine a good candidate for for a docking bay.

Do you perhaps have another USB Type-C charger at hand with a high power output that you could test? Apple-proprietary hardware is known to not always work with other devices.

I don't have another other Tybe-C charger in this moment. Maybe I should buy one to try?

I would rather lend one from a person that might have one. Otherwise you could order one off Amazon or another store and return it if it doesn't work. But when Lenovo says it works, it should work. I just assume incompatibility with Apples proprietary hardware.

Hi DonDon,

 

    I tested anker 60w type-c charger, it doesn't work with Ideapad S740. I know P1 Gen2 does support thunderbolt 3 charging, maybe Lenovo block this function in S740? Maybe? Also, I found someone online says S740 doesn't support thunderbolt 3 charging. If the charging function is blocked, is there anyway to unlock it?

 

 

Best,

Huhanhai

The port has to support it, but it apparently doesn't. Otherwise it would be mentioned in the Product Specification Reference, and it isn't listed there. Thunderbolt doesn't automatically mean Power Delivery, either.
