In this article, I’ll tell you about my experience of using the Dell USB PowerShare feature on my Dell Inspiron N5110 laptop. If you look into the BIOS settings of this laptop, then it appears that this laptop supports USB PowerShare feature. When I actually tested it, I found that this laptop doesn’t supports USB PowerShare feature.
First, let us try to understand what exactly is USB PowerShare feature.
What is Dell USB PowerShare feature?
This feature essentially allows you to use your laptop battery as a power bank to charge your external devices like cellular phones, tablets, etc.
You might be thinking, hey I can do that, what’s new in this. I would just use my phone’s data cable to charge my phone while my laptop is powered on.
Well, this PowerShare feature doesn’t need that your laptop is powered on for your phone to charge itself. You can safely charge your phone while your laptop is powered off. This makes your laptop work as a power bank.
If your laptop supports this feature, then you can also set how much your laptop battery is allowed to discharge itself while charging your phone.
How to find out if my laptop supports USB PowerShare feature?
If any of the USB port(s) on your laptop has a lightning or battery symbol, then your laptop supports this feature.
Does Dell Inspiron N5110 supports USB PowerShare feature?
As I’ve written earlier, this laptop doesn’t supports USB PowerShare feature. Here is what I can see in BIOS settings on my laptop (see Figure 1). If you don’t know about BIOS settings, it is what you see when you press F2 after you have just powered on your computer.
As you can see, you can only enable or disable it. There is no other option.
Why Dell Inspiron N5110 doesn’t supports USB PowerShare feature?
Your laptop BIOS settings have an option to enable the USB PowerShare feature, but your laptop wouldn’t charge your external devices when it is powered off. What can be the reason?
When I googled about this problem, I came across this topic on the Dell support website. I’ll quote here:
Different Dell models have implemented PowerShare differently. On my older XPS 15 9530 for example, PowerShare works even when the system is fully shut down and disconnected from AC. On my newer Latitude E7440, PowerShare only works while on battery if the system is asleep, not shut down. When the system is on AC power, it works while asleep or fully shut down.Dell support community
So, the reason for the USB PowerShare feature not working on Dell Inspiron N5110 is that this feature is configured differently. On my laptop, I can charge my phone while my laptop is fully shut down and also on AC power. It only works on the USB 2.0 port on the left side of my laptop. Sometimes, this also doesn’t work. So, what I do is perform these steps:
- Shut down the computer.
- Remove the AC power.
- Press the power on button once.
- Press the power on button again when the Dell logo appears so that computer is powered off again.
- Connect the AC power.
- Connect the data cable of my phone.
If we speak strictly, then the Dell Inspiron N5110 laptop doesn’t supports USB PowerShare feature. We want to charge our external devices using the charge from the laptop battery while it is powered off. But this laptop only charges external devices when the laptop is powered off and AC supply is also present.
