Charging ThinkPad P51 Notebook via USB-C

2020-08-17, 12:28 PM

Hello,

 

I've tried to research this on Lenovo FAQs/forums/etc. but I am finding conflicting answers.

Is is possible to charge ThinkPad P51 via USB-C port, or is it just for charging external devices?

 

If it's possible to charge the notebook via it's USB-C port, and if so what would be the power requirements for the charger/dock station?

Hello,


The ThinkPad P51 shipped with a 170 Watt Lenovo SlimTip adapter.  The most power a USB-C power delivery connection can provide is 100 Watts, which is 70 less than the P51 needs to charge.  Therefore, a 170 Watt (or the higher 230 Watt) Lenovo SlimTip adapter needs to be used.  Note that using a higher-wattage adapter will not cause any problems, as the laptop will only draw the amount of current it needs from it.

 

Regards,

So that's a "No" then.

Good to know before buying anything.
