Check Battery Health

If you’re not sure if your laptop battery is dead or just needs a charge, follow these steps to check it out.

  1. If the laptop is plugged in, turn it off.
  2. Unplug the power cord
  3. Hold down the power button until the laptop starts up again and then release the button.
  4. Look at the battery gauge on the bottom of the screen to see how much life is left.

If it’s less than 20 percent, the battery is likely dead and needs to be replaced. If it’s more than 80 percent, you can probably just charge it up and keep using the laptop.

Identify the Problem

If you are having trouble recognizing when your battery is low, there are a few things to test.

You can do a quick check of your laptop’s battery status by pressing the power button and then holding down the F2 key at the same time until the BIOS screen appears. Then go to the general panel -> battery health information, this will show the battery charge level in percent.

If you’re getting low on battery life, then it’s time for a new battery.

But if you just notice that your laptop isn’t lasting as long as it used to, there are a few things you can do to troubleshoot the issue and get your laptop back up and running:

-Make sure you’re using the correct power adapter. Many laptops use a specific type of adapter that requires being plugged into an outlet specifically – make sure yours is compatible.

-Check to make sure that your laptop has been properly charged. A full charge will give your laptop more power to work with, which means longer runtime.

-Disable any unneeded programs or features that may be using up resources. This includes programs like antivirus software, graphics drivers, and streaming services.

The Difference Between Original and Rechargeable Batteries

If you’re like most people, your laptop relies on a battery to keep it running. But what’s the difference between an original battery and a rechargeable battery?

And why should you care? we’ll discuss the different types of batteries, how to tell if your battery is dead (or about to die), and some tips for getting your laptop up and running with a fresh battery.

When it comes to laptops, batteries are king. Yes, the computer itself is powerful, but without a good battery, you won’t be able to do much. So how do you know when your battery is about to expire?

What to do if you have a laptop that won’t charge

If your laptop battery won’t hold a charge, there are a few things you can do to check it out.

  1. Try plugging in your charger and turning on your computer. If the computer starts up but the battery isn’t charging, your battery is probably dead.
  2. If the computer will start up but the battery isn’t charging, try unplugging the charger and turning on the computer. If the battery now charges, your battery is probably just low on juice and can be recharged with a standard power adapter.
  3. If your laptop won’t turn on at all, it might be time for a new battery.

FAQ’s

Q. How many percent of battery health is good for laptops?
A. 40% to 80% of battery health is good for laptops.

Q. When is the best time to charge a laptop?
A. Either when you first use it or when you receive it from the manufacturer. Lithium-Ion batteries (the most common type) take about 4 hours to fully recharge, so start charging during that period.

Q. Should I charge my laptop to 100?
A. No, charge to 80 percent or less.

Q. Is it ok to let my laptop sit with the battery fully charged?
A. Yes, as long as you don’t leave it sitting for extended periods of time. Battery life is measured in cycles, so if you need one full cycle (48 hours) to complete your task and you let the battery drain down to 20 percent, then you only get 20 cycles out of a full charge. If this happens on a regular basis, then consider purchasing a new battery.

Q. Will my laptop work at 4% battery health left?
A. Your laptop should still function correctly with 4% or less health left; however the longer a battery sits idle the less effective it will become and the shorter its life will become.

Conclusion

Assuming that your laptop battery is not dead, these are the few things you can do to determine whether or not it’s just drained and needs to be charged, or if it’s actually broken and needs to be replaced.

If you don’t have access to a power outlet, you can try connecting your laptop to an external battery pack (or use a power adapter) to see if that will help.

If you don’t have access to either of those options, then you’ll need to take your laptop in for repair or replacement.
