I forgot my charger at home, so i went looking for alternative ways to charge my laptop.

Laptop: HP Probook g7 (Without touchpad, and keyboard lights)

Lets get to the problem..

I got a bright idea:

My phone can charge from USB-C cant laptops aswell?

i quickly googled: HP Laptops can chargw from USB-C, i tried and it worked. But only when 100% powered off, After POST (After leaving the bios) it would stop charging.

 

This problem is only with USB-C, But i havent tried with the standard AC as i forgot it at home.

 

But then it stopped charging from USB-C after running out of battery after one charge. i began googling found it can blow capitors in the pc with low-wattage usb-c, But then i found HP says its fine:

TLDR:

 

Is it bad to charge hp probook g7 with a low wattage USB-C (can i blow the capitors)? or is hp correct or did hp mean that i needed a power brick?
