The most common reason this happens is that the battery ran out of power completely. If your original battery still charges and discharges but your Xtend replacement battery will not, the new battery may have run to 0% or it may be a defective unit. This may be an indication that you need to replace your AC Adapter.

Make sure you are connected to the Internet, the check for updates. If your battery isn’t fully charging, the first thing you can try is the Battery troubleshooter in Windows 10. Complete the wizard then restart your device to see if the problem is resolved.
If the battery on your computer is only charging to 80% this is likely because Battery Life Extender is turned on. Battery Life Extender sets the maximum battery charge level to 80% in order to extend the life of your battery.
If your system can only be charged to 55-60%, it may due to conservation mode or the custom battery charge threshold may be turned on. Go to Device, My Device Settings, Battery. If you are using Lenovo PC, set conservation mode to off. If you are using Think PC, set the custom battery charge threshold to off.
To extend the lifespan of your battery, if the battery gets too warm, software might limit charging above 80 percent. Your iPhone will charge again when the temperature drops. Try moving your iPhone and charger to a cooler location.
If the battery is charging only to 99% all the time it could be the battery wearing down . It could be background running apps that are draining enough power from the battery to interfere with the trickle charging so the battery does not reach it’s full signal for cut off .
Laptop Battery Power Cycle: Power down the computer. Unplug the wall adapter. Uninstall the battery. Press and hold the power button for 30 seconds. Re-install the battery. Plug in the wall adapter. Turn on the computer.
If the battery continues to charge for not more then 85% then please update the BIOS via this link. You may perform the following steps from this HP document to test the battery and also calibrate it. Test the AC adapter using the UEFI Hardware Diagnostic tests. Troubleshooting the notebook battery.
The classic Control Panel will open to the Power Options section – click the Change plan settings hyperlink. Then click on the Change advanced power settings hyperlink. Now scroll down and expand the Battery tree and then Reserve battery level and change the percentage to what you want.
As we mentioned, you can increase your battery’s lifespan by only charging your máy tính to less than 100%. Don’t leave your computer anywhere where the temperate is over 86℉ since high heat can damage your battery and decrease its lifespan.
The best thing you can do is try to keep the battery level between 40 percent to 80 percent. Make sure that your máy tính doesn’t get too hot and your cooling fan is working properly. Your máy tính battery can’t “overcharge” and harm itself due to excessive charging. It’s smart enough to bypass the charging energy.
Overheating a battery will shorten its life, so some computers stop charging at 99%. Macbooks in particular are known to fluctuate between 97% and 99% when plugged in to “condition” the battery. If it stays at 99% even after long use unplugged, you may need to recalibrate it. Some computers let you do this in the BIOS.
This could be due to a hardware component failure. Try the following options to troubleshoot: Clean the charging port of the phone to remove any dirt or debris stuck in the port. Charge the phone using the original charging cable from a wall charger.
Effective ways to maintain an Android device’s battery health Make use of ‘Power-saving mode’ Restrict app usage on your Android Smartphone. Turn off ‘location services’ Enable ‘optimized battery charging’ feature. Use the ‘Auto-brightness’ feature. Don’t use the iPhone in extreme temperatures. Use ‘Low-power mode’.
If the amps or watts is normal, then the phone is charging normally but the phone is doing something that uses a lot of electricity so the battery percentage remains the same or only slowly goes up. Like bailing out a boat with a leak.
Android devices have a lot of threads running while iOS kills tasks more efficiently. This drains the cells fast and causes cell reversal. Cell reversal leads to quick drainage, longer charging times and more demands more ionization energy.
It takes a lot of physical energy to increase the charge from 99% to 100% since there is already a large amount of charge in the battery. One contributing factor is the amount of electric/magnetic field strength inside the battery, essentially making it “saturate” with electric charges.
This is normal. The batteries used in these computers are designed to avoid short discharge/charge cycles in order to prolong the overall life of the battery. To allow the adapter to recharge the battery to 100%, simply allow the charge to drop below 93%.
Go to BIOS setup of your máy tính → Advanced Tab → Battery life cycle extension → Change the “ Enabled “ to “Disabled”. If battery goes to 80% in few minutes and then goes back to 10% in few minutes, replace your battery as soon as possible to avoid damage to your SSD. Check the battery/ power settings.
Laptops are designed for portability and battery life plays a great giảm giá in achieving this. Without a battery, your máy tính is in no way different from a stand-alone desktop PC since you will always need a power outlet. Many of us, if not all, have come across the “n% available, battery plugged in, not charging” message on the battery meter icon. The percentage charged may vary and can be anything between “0% plugged in, not charging” to “99% plugged in, not charging.” Unplugging your AC charger when the charge is less than 5% will turn off the máy tính. This article seeks to give reasons why this issue occurs and give known solutions to the problem.
There are numerous reasons why your battery would not charge. You might want to try your charger on another máy tính (same make), or switch your battery to another máy tính (same make) in order to diagnose the problem. Also, try charging with your OS shut down; if it does not charge then the Windows OS is not the issue. If your charger is genuine and works on another máy tính, try swapping the battery, if that works too then your charging system might have a problem and can be anything between mild to a severe issue that might need component replacement on the motherboard circuit.
Most of the time, this issue occurs because of a misalignment between the battery and charger. Discharging and resetting your máy tính will work for such cases. If you are using the wrong charger or the wrong battery for your system, then you will definitely get this problem. Some laptops like Dell give a warning message at startup indicating a wrong charger wattage, or battery voltage. The battery drivers (yes, they have drivers too) might also be a culprit in this issue and will need an update or reinstallation. The problem might also be related to out of date BIOS or BIOS configuration. Those people that use power conditioning equipment (e.g. surge protectors) have also experienced this problem. Some laptops have intelligent charging systems and will stop charging when charged to 100% then resume charging when the battery level falls down to 80% or 90%; so don’t be alarmed when you see this.
Below are the solutions to the ‘battery plugged in, not charging’ problem. We will begin with simple solutions and advance to more complex solutions.
By simply unplugging your AC charger and plugging it back in after a few seconds, you can get your battery to charge again. The charging system will recalibrate and realign your battery with the charging system and have it charging again.
Power surge protectors or other power conditioners can change the sinusoidal input of the mains AC hence your charger does not function as anticipated. Most systems can pick these irregularities and refuse input from the charger to the battery. Try connecting your charger directly to your socket without going through a power surge protector or an extension plug. Also, check the connections between the outlet and your DC port.
You must at least have some power on your battery for this. Remove your AC charger, boot your system until all icons are displayed, and then plug in your charger.
Some batteries do not charge if they are not locked into their port. This is because the battery release lock is incorporated into the charging circuit somehow. Simply turn your máy tính over and make sure the release lock is flipped to the locked position.
Charging your battery to 100% and leaving your charger still plugged in significantly reduces your battery lifespan. Storing your battery at 0% and can also do the same other than being an inconvenience when you want to head out. Most laptops have now incorporated an intelligent charging system to handle charging cycles.
If your computer says that the battery is not charging at around 80 to 97%, then this is not a defect or a problem. Your battery firmware or software driver is probably configured to forego charging when the battery is very near to 100%. Remove your AC adapter, let the máy tính discharge for a while to below 80%, or 50% for some laptops, and then plug in the AC charger. It should resume charging automatically below a certain threshold.
If you are not pleased by the intelligent charging system, you can disable the behavior on your computer. Remember that this will affect your battery longevity. Simply look for you a battery life extender app on your máy tính and change the behavior to normal.
For Samsung laptops, you can find it here: Start > All Programs > Samsung > Battery Life Extender > Battery Life Extender and then change it to normal mode.
Some like the Sony VAIO lets you choose a life extender percentage or turn it off completely.
For Lenovo, you can switch it to optimize runtime rather than lifespan.
Other laptops can also toggle this behavior from within the BIOS; just press F2 or F10 during booting in order to enter the BIOS.
This will discharge the capacitors on the motherboard, and force the battery to be recalibrated and realigned with the charger.
If the problem is related to the firmware settings, you can reset the BIOS by:
You can also try updating your BIOS since this controls charging too. You can find our guides on this here.
The drivers control the charging meter and how your PC charges when you have booted into your operating system. Uninstalling them will let Windows reinstall the correct drivers from its repository.
WARNING: Do not remove the Microsoft AC Adapter driver or any other ACPI compliant driver.
Try disabling then enabling your drivers in step 4 above instead of uninstalling.
Updating drivers will install newer drivers that are compatible with your OS. You can search for drivers from your manufacturer or:
You can also try updating your BIOS. You can find our guides on this here.
Most laptops let you check the health of your battery from the BIOS advanced tab. They can also tell you if your charger is identifiable. Just press F2 or F10 during boot to go into BIOS; you can find battery and charger information in the ‘system’ or ‘advanced’ tab. If your charger is unknown or unidentifiable or indicated as the wrong charger, you might need to replace it. If your battery is indicated as ‘failed’ or of poor health, then you might also need to replace it.
If you are absolutely sure that your charger and battery are in prime condition and are the correct ones for your máy tính, then you might want to have the charging system on your motherboard checked out.
Tip: Batteries usually need replacement after 3-7 years. The battery should be stored at 50% when not in use for a long time to prolong the life of the battery. It should also not be drained to 0% often. Maintain a good recharge cycle to give your battery a longer life. If your máy tính does not have an intelligent charging system, do not leave it plugged in all the time. Let the battery discharge a little before charging it again to 100% in order to enhance its life length. Do not let your computer or battery overheat especially when playing games or running software that needs a lot of power.
Run a battery test of HP: open the HP Support Assistant –> Troubleshoot –> Power, Thermal and Mechanical. In the Power, tab click on Battery check. If you do not get a pass or OK on the battery check, then contact HP Total Care for warranty service.
