Re: USB-C Compatibility (including Power Delivery)

Hello curryfishball,

 

normally we can't say anything to the compatibility of options from other brands, as we have not tested these.

 

According to the ASUS website the Power Consumption (Typical) is <7.5W, using a normal USB 3.0 port.

The X270 has two such ports (Two USB 3.1 Gen 1 (USB 3.0, one Always On), USB 3.1 Type-C Gen 1):

Therefore I don't se a reason why it shouldn't work.

If in doubt, you can use the powered USB port ("Always On"), as it is probably the port with "more juice"...

 

But like I said: Not tested... Therefore we can't guarantee it.

Re: USB-C Compatibility (including Power Delivery)

Dear OEM Chen,

 

Do you know if ThinkPad 13 supports DP alt Mode?

 

From an online website (Laptopmag) is state only data and charging is supported on the USB-C port.

 

Thank you!

Re: USB-C Compatibility (including Power Delivery)

Is the USB-C meant to deliver what it can to stabilize battery usage? I have a P27h connected to an X1 Extreme and there is no power delivery between the two. The X1 came with a 135W charger, but I have a 90W charger that came with an older laptop that does just fine, it just charges more slowly. My expectation was that USB-C would deliver the ~100W and I'd get similar performance to the 90W charger, but that isn't at all the case. In fact, battery use is REALLY high when plugged into the monitor (as in I've lost 6% while writing this message). Is this typical behavior? Other than the need for the power cable, I love the setup.

Re: USB-C Compatibility (including Power Delivery)

@headphones54321:

The X1 Xtreme really needs the 135W PSU.

The power output from the USB-C Port is simply too low for this model, so this situation is to be expected.

I guess you will have to continue using an additions power source...

Re: USB-C Compatibility (including Power Delivery)

Hello CliffBau,

 

according to the specs ( http://psref.lenovo.com/syspool/Sys/PDF/ThinkPad/ThinkPad%20P1/ThinkPad_P1_Platform_Specifications.p... ), this ThinkPad has these ports: "Two USB 3.1 Gen 1 (one Always On), two USB Type-C / Thunderbolt 3, ...".

If the Thunderbolt USB-C Ports are used, then Alt Mode for video output is no problem...

(whether the two Non-Thunderbolt ports support Alt Mode, I can't tell... but that won't be relevant, right?)

Re: USB-C Compatibility (including Power Delivery)

What's about Yoga Book C930.

 

The PD profile is not mentioned here https://psref.lenovo.com/syspool/Sys/PDF/Lenovo%20Tablets%20_%20Convertibles/Yoga%20Book%20C930/Yoga...

 

The supplied delivered wallcharger outputs 9V/3A, if I'm refering to that https://www.st.com/content/ccc/resource/sales_and_marketing/presentation/product_presentation/group0..., it should be profile 3 (36W).

 

So my question is : does the Yogabook accept 12V input voltage (for example, from a power bank unable to deliver 9V/3A but 12V with less intensity).

 

I use a wallcharger delivering 9V/12V/20V at 3A, it works fine with the Yoga Book C930, but I don't know it the laptop makes use of voltage over 9V.

 

Best regards.

And we're back...
