YSK: If your laptop has a USB port with a lightning symbol next to it , you can use it to charge your phone or accessories without switching the laptop on .

If the symbol is there but it doesn’t work, check your BIOS, you’ll have an option to enable usb power delivery . You can enter the BIOS only during startup (before you see the windows icon) by pressing a key specific to your system manufacturer. It’s usually one amongst the function keys or DEL key in some cases . You’ll have more information in your instruction manual .

Note: Was posted to LPT but the mods said it wasn't fit to be a LPT and removed it. Thought you guys might find it useful.
