Problem 3: Peripheral Devices Connected With Your Dell Laptop:

Sometimes, if you have connected any external device with your Dell laptop, it will start consuming more battery from the machine.

Any output device such as an external monitor, printer, scanner, or USB will make your laptop suffer in these regards.


If you have connected these devices and see quick drain-outs in your laptop’s battery, take a quick note and remove such external devices from the laptop’s ports.

Problem 3: Keyboard’s Backlit Problem:

In most cases, if the laptop is showing faster battery dropouts, you must consider whether your laptop has a backlit keyboard or not.

Magic or backlit keyboards have buttons embedded on them that work with the Function key or Alt Key combination.

You can find this button for the keyboard light and turn it off if it is on, causing your laptop to drain more battery.

Problem 6: Multiple Networks Connectivity:

Sometimes your laptop might be connected to more than one network to ensure faster and better internet performance.

Or you might have arranged these connections in case of emergencies. When you do that, a laptop takes a good amount of power to change its network connectivity from one source to another.

So, you must always have a solution for this.


You can manage this Network connectivity by searching for Network Connection in the Windows Search Bar. A new window will be in front of you, just like the one below.

You can remove the unneeded networks and make sure that your laptop should not lose its battery on these connections.

Problem 7: If The Battery Is The Problem:

Usually, laptops start draining batteries not because they are doing multiple activities or have something special running on them.

But a battery itself might be an issue. In that case, nothing works out even after applying all the solutions stated above. The problem could be with the battery of your laptop. Batteries get defective and start losing power more quickly.


Order a new battery and check it on your laptop to see if this one performs better than the previous one. In this case, if it does, the problem with draining was with your battery. It will be fixed by doing this.
