Yoga C930 - power questions

Yoga C930 can be powered using one of the USB type-C port using the provided 65W adapter.

1. If I plug in the adapter cord in the other USB type-C port (which is not made to be used as power port) what happens?

2. Can I use a Lenovo USB type-C 45W adapter with C930?

Thank you

1. Nothing. USB-C ports are allegedly "smart" in that they know what's connected them and how to react. 

 

2. Other than charging speed, no big deal. I interchange USB-C chargers all the time. Only the USB-C phone chargers aren't of much use. 5V just doesn't get the job done.

Re: Yoga C930 - power questions

I purchased a Lenovo Yoga c930 last week and it got delivered today. I have been experiencing issues with the sleep and power options. As soon as I click the button to eject the pen, the laptop goes into sleep mode where I have to sign in again. The situation gets worse because sometimes the laptop would shut down randomly when the pen is ejected out or it is inserted back into the laptop. Does anyone have a solution for this issue or anyone faced a similar issue?

I think i know the answer to your question. The pen has nothing to do with the sleep mode. What happens instead is that the location of the power button is rather idiotic and you accidentally press it while putting the pen in.

That's also just a 5v charger. It might work, but not nearly as fast as one that'll do higher voltages.  

 

Note: any charger with USB-A ports will only supply 5v. SOME chargers with USB-C ports may supply higher voltages, but you'd need to look at the specs. I've seen some that do 5v and 12v. If you connect a 12v charger to a computer that's looking for 19v, it'll fall back to 5v and likely nothing or not much will happen. The best ones will have a hard-wired USB-C cable and list several voltages including one that matches the spec of the laptop. Even then, it's possible a third-party charger is only compatible with a few brands.  Best to use Lenovo chargers.
