How To Get A Dead Laptop Battery Working Again

Laptops, just like other electronic devices, have batteries that typically last for about a year. But if your battery starts dying on you before then, what should you do?

At one point or another, all of us have run into the problem of our laptop’s battery dying. This is a frustrating experience when you have a paper due at the end of the week and need to be able to plug in your laptop to get your work done.

This article will tell you all the steps to take to get a laptop battery working again and Increase Laptop Battery Life In Easy Steps.

The Basics of a Dead Laptop Battery

If you find yourself with a dead laptop battery, there are a few basics you need to know in order to get it working again.

First of all, make sure your laptop is plugged into an outlet and the power cord is connected. If the battery is completely dead, this may not be the case, so try turning on the laptop and seeing if it comes on. If it does not, then your battery may be completely dead.

Another basic step is to make sure that you have charged the battery recently. Laptops use a Lithium-Ion battery which will lose power over time if it is not regularly charged.

To charge the battery, plug the charger into an outlet and plug the cable into the laptop. Once plugged in, wait for the laptop to say “charging” before unplugging it. It should take about 3 hours for a full charge.

How to Jumpstart a Dead Laptop Battery

When your laptop battery dies, you can’t just plug it in and expect it to start up. Your computer needs some help to get going.

Here’s how to jumpstart a dead laptop battery:

  • Remove the battery from your laptop.
  • Place the battery in a metal container that is large enough to fit all of the batteries’ terminals and screws. Make sure that the container has a lid or cover so that the batteries don’t touch each other.
  • Connect one end of an electrical cable to the negative terminal on the battery and connect the other end of the cable to an outlet or another power source.
  • Put the battery back into your laptop and turn it on. You will now see a green light on the charger indicating that it is charging.

If this will not work then you may have to change your laptop battery.

What are the Challenges of Jumpstarting a Dead Laptop Battery?

There are a few challenges when it comes to jumpstarting a dead laptop battery. The first is figuring out whether or not the battery is truly dead.

If the laptop is turned off and not plugged in, the battery should be able to take a short burst of current to test its condition.

If it’s still dead, you may need to remove the battery completely and try to jump-start it that way. If the laptop is plugged in, you can try using a power adapter or USB cable to give it a short burst of current.

Another challenge is that batteries can occasionally leak corrosive chemicals that can disable a laptop battery. In some cases, this may only require rinsing the battery with water and drying it off. However, if the battery is severely damaged, you may need to replace it.

There are a lot of factors that can make jumpstarting difficult. For example, is your laptop in the middle of an OS upgrade? Does it have a defective battery? Is the battery old and weak? Are you sure there’s enough voltage to apply to the battery?

Ease of jumpstarting is a factor too. Does your battery have an easy-access jumper or connector? If it does, an expert could simply connect the jumper to start the laptop and then switch it back off to let the battery recharge.

If not, you might need tools like a multimeter or an ohmmeter that can measure voltage in order to figure out how much power is flowing through your laptop’s battery.
