How to Reset a Laptop Battery That Isn’t Being Detected or Charging?

Plugging in one’s laptop would seem to be the logical thing to do when there’s a problem with it. But what happens when you press the power button only to find that your device is completely dead? You plug in the cord and wait for it to start charging, but nothing happens.

What should you do now? Should you just rush out and buy another battery since your current one is clearly “dead” even though you swore yesterday that it was working fine? Well, it may turn out that you are, in fact, just dealing with a faulty battery.

The solution, of course, will be to take your product in for a simple battery testing to see whether the problem is being caused by a faulty product rather than something else entirely (unnecessary or otherwise). It’s important to rule out this possibility because when you’re unsure as to what is causing the error; you may end up buying a brand-new battery. Only for it to become apparent later that this was an unnecessary action and ultimately one step farther away from finding the real root cause of your issue.

The best way to deal with a malfunctioning computer or any other seemingly broken device is by resetting the system first before going overboard and buying more components – which may just be another waste of money!

Possible Reasons of Undetected Battery or Battery Not Charging

Laptops that show a flashing red light are often confusing to people. Before you panic or run for the Dell laptop battery replacement, make sure you have checked the possible causes. Maybe you could find a way to make your laptop work with little effort. Some of the potential reasons are listed as follows:

  • The battery may not be properly seated in the laptop.
  • A power surge or fluctuation caused damage.
  • The battery may be faulty due to being overcharged.
  • Battery removed from the laptop during charging or other causes.

Solution for Undetected Battery or Battery Not Charging

You might just need to reset your system’s ability to detect the battery in certain cases. Unfortunately, many of Dell’s technical support staff are unaware of this process, quite possibly too busy (or pressured) to tell you this. Instead, they want you to replace the battery. Of course, it is somewhat hard for a technician thousands of miles away to know the difference between a truly failed battery and a faulty one misidentified as such by being unable to be detected properly by said machine!

Therefore, help yourself and try one last resort – a full discharge cycle and then recharge again before even thinking about throwing away your current battery.

  1. Turn off the charging and remove the cable from your laptop.
  2. Let your laptop battery be fully drained
  3. Now turn around your laptop and remove the battery simply by pushing the battery release button.
  4. Turn your laptop around and plug it in again. Let it boot completely and again turn it off completely.
  5. Remove the cord again.
  6. Flip your laptop upside-down and re-install the battery.
  7. Attach the charging cable.
  8. Turn it on.
  9. Let it charge and boot again.


If the issue was the battery sensor, then after this reset, the laptop should now detect the battery correctly. Unfortunately, if you are still having trouble with your battery, there may be further problems with the computer, or even a new battery may need to be installed.
