Sometimes your smartphone battery is drained out or your iPod battery is drained out and an AC power source is not available or an AC travel charger is not available. In such a situation, you can use your laptop to charge your phone or other device of course via a USB data cable. But what if you do not want to turn on your laptop to charge your phone? Or you don’t need to open your laptop screen?

Enabling USB power settings may lead to faster laptop battery drain. So use these settings as per your requirements and priorities. The settings and features explained in this article can be model/Windows version dependent, hence you should test and apply only what works for your setup.

Charge Smartphone even When Laptop is Powered Off

First thing you need to make sure that eSATA/USB port is available on your laptop. You can easily figure this out by noticing the following image like port on your laptop.

So eSATA/USB port is available on your laptop, right?

That’s good news.

Don’t be sad if eSATA/USB is not available on your device. You can check if USB Powershare option is available for regular USB port under your BIOS Setup, if it is there you can follow the next steps.

Next, you need to check in your “BIOS Settings” whether the necessary setting is “Enable” to get power through eSATA/UBS port even when laptop is powered off. Follow these steps to enable USB Powershare option under your device BIOS setup:

Step 1: Turn off your laptop.

Step 2: Turn it on and press F2 key to enter into BIOS Setup.

(In case of DELL Devices F2 is the key to enter into BIOS Setup, if your laptop is of other make, after pressing power key to turn it on, keep your eyes on the screen and see which key is to be pressed to enter into BIOS Setup. You can also Google the procedure to enter into BIOS setup of your device. For example BIOS setup of DELL xps 14, BIOS setup of HP 14S, etc.)

Step 3: Navigate to Advanced tab using the arrow key & select the USB Powershare option and Enable it. If it is already not Enable.

Step 4: Save Changes and Exit BIOS Setup. It’s done. You are ready to go.

Now Turn Off your laptop and plug in phone’s USB data cable to eSATA/USB port and connect it to your phone. Your phone should start charging.

Using this port you may also charge other devices like iPads, Tablets, etc, the devices which can be charged using a USB data cable.

I have tested this method with DELL XPS 14 and DELL Inspiron 14, and it works like a charm. I hope this guide will be useful for you. Please share your experiences in the comment section below and also mention Brand and Model of your device.

    • 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.

    To those who have it working but need the AC power plugged in, have the laptop in sleep mode (not shut down). Worked for Dell G5.
