The laptop battery is an instrumental component in the entire laptop system. The battery is much expensive to replace; thus, care measures must be taken. The laptop battery is attached to the computer's system; hence the system plays a significant role in its maintenance. Sometimes, your battery might zoom from half full to nearly empty in a short period. Sometimes, you might plug in your charger then unplug, and only to see what you thought was 100 percent is 95 percent.
The above scenarios occur when your laptop battery is reporting incorrect charge information. Thus, meaning that your battery might not be adequately calibrated. It is always essential to have your battery calibrated to know the condition of your battery. However, the way you handle your battery doesn't matter; its capacity will decrease due to unavoidable factors such as usage, age, and heat.
Therefore, we need to know what battery calibration means, methods of calibrating the battery, and the effects of failing to calibrate your battery. This article will answer all your questions, thus follow through and learn.
There is no reliable method that you can use to find your battery's exact capacity at a given time. The only reliable way to determine it is to fully charge the battery and then fully discharge it and measure it. Thus, this is one method of calibrating the battery. Battery calibration is a method of resetting the battery's system to make it give accurate readings.
Calibration helps keep the estimates correct by setting new full charge and full discharge anchors in the battery system to avoid guessing. Always make sure that you allow the battery to run from 100 percent to 0 percent. This helps in keeping the battery's power meter in check, thus giving accurate readings.
Manufacturers usually advise users to calibrate their batteries every 2-3 months to keep the battery's reading accurately. Failure to accurately calibrate your battery can lead to a laptop dying suddenly without any warning. The process of calibrating the battery is not challenging.
How do you calibrate your laptop battery·
The process of calibrating the laptop's battery is straightforward. However, there are various methods of calibrating the battery. You can use this most straightforward method of charging the battery to 100 percent. Then, allow the battery to run from 100 percent to about 0 percent. The battery's power meter will measure how long the battery lasts and get a correct idea of how much capacity the battery is left with.
Some laptop manufacturers add a utility that will calibrate the battery for you. These tools ensure that your laptop has a full battery, disable power management settings, and permits the battery to run to empty. It allows the battery's internal circuitry to get an idea of how long the battery lasts. Check the manufacture's web for information on using any of the utilities that they offer.
You can also calibrate the battery manually, using BIOS or using third-party software. Therefore, let us look at how to calibrate the battery with these methods.
Calibrate the battery manually.
It is a good idea to use any included utilities or follow instructions given on your laptop. The necessary process is simple:
·Make sure you charge the battery to full – that is a full charge to 100 percent.
·Allow the battery to stay for a minimum of 2 hours, leaving the computer plugged in. This will ensure that the battery is cold and not still hot from the charging process. You can use the computer freely while it is plugged in, but always check to ensure it does not get hot.
·Visit the computer's management settings and set it to hibernate at 5% of the battery automatically. To find these options, head to Control Panel>Hardware and Sound>Power Options >Change plan settings>change advanced power settings. Then go to the "Battery" category for the "Critical battery action" and "Critical battery level" options.
·Unplug the charger and leave your laptop running and discharging until it automatically hibernates. You can continue using the computer while this happens.
If you want to calibrate the battery while you are not using the computer, ensure that your battery is not set to automatically sleep, hibernate, or turn its display off while idle. If your battery enters power-saving mode while you are far, it will save power and won't discharge properly. Visit the Control Panel>Hardware and Sound>Power Options>Change plan settings to get these options.
·Make the computer to sit for five hours or so after it automatically shuts down or hibernates.
·Plug back your computer into the outlet and charge it back up to 100 percent. You can keep using your computer just the usual way while it is charging.
·Make sure that any power management settings are well okay at their average values.
Your laptop should now be giving a more exact amount of battery life than before. It won't give you surprise shutdowns and will offer a better idea of how much battery power you have at a given time.
Calibrate Laptop Battery Using BIOS
Your laptop must have a built-in Battery Calibration program (in its BIOS) to you this method. Follow the following steps:
·Switch off your laptop and power it on again.
·Enter the BIOS by pressing the “F2” key at the boot menu.
·Use the keyboard cursor keys to select the "Power" menu.
·Circumnavigate to "Start Battery Calibration" and click on the "Enter" key (this action will change your screen background to blue). start battery calibration
·Trail the on-screen command and plug in your laptop charger.
·After your laptop‘s fully charged (100%), disconnect the charger.
·Let the battery drain (discharge) from 100% to 0%; until it automatically powers off.
·Connect up the charger (do not boot your system while it is charging).
·Once it’s fully charged, the calibration procedure is complete.
·You can then disconnect the charger and restart your system.
Failure to calibrate your battery can lead to sudden shut off of your laptop. Your laptop's battery can die before you even notice at all. It is good to know the condition of your battery earlier so that you can increase its lifespan.
Always monitor your laptop battery to ensure that it lasts for an extended period. Do not wait until your battery dies. Do your part and leave the rest to the computer system.
