Hey Chandu,
Check if ‘USB Powershare’ option is available under BIOS settings. If it is there. You can enable this option and can check if you are getting power via USB port in power off state. Thanks for stopping by.
I tried in DELL Lattitude 3340, it worked only when I connect the laptop in AC.
Hey Arundev,
Glad that you made it. It may also depend on the hardware configuration of your machine.
Thanks for stopping by.
I tried it as well, works only when connected to ac power, Dell Latitude E6440.
Is there a way to let it charge when not connected to power?
Hey Geofrey,
It should work when laptop is on battery backup. However, these features are model dependent. May be your model is designed to work that way only.
Thanks for stopping by.
