Should I remove my laptop battery when using the AC adapter?

When you’re using your laptop near a power outlet, it’s a good idea to plug in the AC adapter to power your laptop .

 Your laptop battery takes full advantage of power outlets and saves battery power when no power outlets are available. You can leave the battery connected to the laptop while using alaptop AC adapterto power the laptop.
Benefits of keeping the battery in your laptopThere is no need to remove the battery, there are benefits to keeping it.


First, if the battery is not fully charged, connecting it to the AC adapter will allow the AC adapter battery to fully charge over time.
Secondly, having a backup battery is helpful in case of power outages and brownouts. If either happens, you won’t lose any data because your laptop will switch to battery backup.


Finally, even when fully charged, keeping the battery connected while using the AC adapter will not damage the battery. Over time, all batteries eventually lose their ability to power your laptop and need to be replaced. This is normal for the battery and not a side effect of using the AC adapter with the battery connected.

When and how to remove a laptop battery while plugged in
If you have a removable laptop battery, sometimes removing it while the laptop is connected to an AC outlet can actually optimize your AC adapter battery life. However, if a power outage occurs while your laptop is plugged into an outlet without a battery, there is a risk of data loss.


Given the inconvenience of a power outage and the risk of data loss, is removing the battery worth it? In some cases, yes. We’ll look at when you should remove the battery from your laptop to optimize battery life, and explain how to do it.
Thermal issues and battery lifeOverheating is one of the worst things that can happen to your laptop battery. Battery life may be negatively affected when a battery is fully charged and heated for an extended period of time (such as when a laptop is plugged in and used).


If your laptop is on your lap, you may feel the heat generated by the battery. Placing pillows or blankets between you and your laptop will only exacerbate the problem, interfering with air circulation and the laptop’s ability to cool itself.
Resource-intensive tasks such as gaming and multimedia editing may further increase the heat generated by your laptop.


When to Remove a Laptop BatteryIf you’re going to be using your laptop connected to AC power for an extended period of time, especially if you’re performing heat-intensive tasks, removing the battery is a worthwhile step to take to extend its life. However, if you have frequent power outages at home or there are storms outside that may cause outages, keep your laptop battery connected and avoid the risk of data loss.
If you have an uninterruptible power supply (UPS) plugged in, no need to worry, just remove the battery.


If you’re on the road and plan to only keep the power on for an hour or so before needing the battery again, leave the battery connected. The process of shutting down the laptop, removing the battery, then restarting, then shortly powering down again to reconnect the battery (and turning the laptop back on again when reaching the next stop) is very inconvenient and time-consuming. When moving, keep the battery plugged in for short periods of time.
If you won’t be using your laptop for an extended period of time, such as on vacation or even on the weekends, it’s a good idea to remove the battery. This allows the battery to rest and potentially extend its life.


Do not remove or reinsert the battery while the laptop is running or even in sleep mode. Whenever you want to connect or disconnect the battery, it’s best to turn it off.
How to remove a laptop batteryWhen removing the battery from your laptop, be sure to perform these steps in this order.
Close the laptop.
Unplug the power cord from the laptop battery AC outlet.
Remove the battery.


Reconnect the power cord to the AC outlet.
Power on your laptop.
Storage Laptop BatteriesThe most common advice for laptop battery storage is to charge it to about 40% (or between 30% and 50%) and then store it in a dry place. Some manufacturers recommend storage temperatures between 68 and 77 degrees Fahrenheit (20 and 25 degrees Celsius), not too cold or too hot.
Some people keep batteries in the refrigerator, but this is risky and unnecessary. Doing so may damage the battery when it is exposed to moisture and condensation. Moisture and computer components don’t mix well.


You only need to remove the battery from your laptop if you need to perform a hard reset to power the laptop or replace internal hardware. Apart from this, the battery should always remain inside the laptop.

Why does my Laptop AC adapter not work?

If you’re having trouble with your laptop’s AC adapter not working or not working properly, there are a few things you can check before buying a new one.


Verify that the adapter is plugged into the wall outletMake sure the AC adapter is firmly plugged into the wall outlet. Although it sounds obvious, adapters can become loose without your knowledge. If it’s partially plugged in, it may make the adapter look like it’s not working, but it may not be getting power from the wall outlet. When in doubt, a good way to ensure proper insertion is to disconnect and reconnect the plug.
Check the adapter lightMany laptop AC adapters have a power light on the adapter block. Check this light and make sure it lights green if there is one. The power light indicates that the adapter is receiving power.


Check the wall socket itselfSome wall outlets require the light switch to be in the on position to activate the outlet. Many newer homes, condos, and condos come equipped with this type of wall socket. If the light switch is on, verify that the wall outlet is working properly . Use a voltmeter to measure power output and verify that the outlet is functioning properly. Alternatively, you can try another wall outlet. Also, double check your circuit breakers to make sure nothing has tripped or turned off.
Check adapter block connectionsMost laptop AC adapters come in two parts. Make sure the two parts are firmly connected. The two pieces are joined at rectangular box pieces (often called bricks). You can verify the connection by disconnecting and reconnecting all cables.


Adapter not plugged into laptopAlthough it may seem obvious, the   laptop adapter can easily become disconnected from the laptop. The metal tip on the adapter cord needs to be securely connected to the laptop for the laptop to receive power from the adapter. Additionally, there is usually a small metal pin on the tip of the adapter or where the laptop connects. Make sure this pin is not bent or broken, as this may cause problems with the laptop receiving power from the adapter.


Laptop power connection portThe power connector usually connects directly to the laptop’s motherboard via one or more solder joints. If the solder joints are damaged or detached from the motherboard, the laptop will not be able to power from the AC adapter. Fixing this problem requires very precise work, either soldering the power connector back to the motherboard or replacing the power connector itself if it’s defective. Sometimes, such problems cannot be repaired and require replacement of the motherboard or power strip.


If you think this might be your problem, it’s best to leave it to a technician, who may need to take the laptop apart to check the hardware.
alternativesIf you determine that your laptop AC adapter is not working properly and needs to be replaced, you can obtain a replacement from your laptop manufacturer.

Works with many laptop brands and models. Make sure the adapter you buy matches the specifications of your existing AC adapter, including voltage and amperage.You also have the option of purchasing a universal AC adapter from a local or online electronics retailer. Chicony is a brand to look for, it’s a quality brand and a popular choice. Chicony AC Adaptersmake high-quality adapters Also, check the packaging to make sure it fits your laptop make and model.
