How to Fix ‘Plugged in, Not Charging’ on a Windows Laptop

Laptops are designed for portability and battery life plays a great deal in achieving this. Without a battery, your laptop 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 laptop. This article seeks to give reasons why this issue occurs and give known solutions to the problem.

Why your battery does not charge when AC is plugged in

There are numerous reasons why your battery would not charge. You might want to try your charger on another laptop (same make), or switch your battery to another laptop (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 laptop, 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 laptop 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 The problem might also be related to out of date BIOS or BIOS configuration.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.

Method 1: Unplug and plug back your AC charger

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.

Method 2: Connect directly to AC source without a power surge protector

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.

Method 3: Do not plug in till the system has fully booted

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.

Method 4: Flip the battery release latch to the lock position

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 laptop over and make sure the release lock is flipped to the locked position.

Method 5: Let your computer discharge for a while

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 laptop 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.

Method 6: Turn off battery life extender

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 laptop 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.

Method 7: Discharge your motherboard

This will discharge the capacitors on the motherboard, and force the battery to be recalibrated and realigned with the charger.

  1. Shut down the system.
  2. Disconnect any external peripherals (flash drives, printers, external hard drives, mouse, keyboard e.t.c.) from the computer.
  3. Disconnect the AC Adapter and remove the battery from the laptop. If your computer does not have a removable battery, there is usually a tiny hole at the back that you can poke with a paper clip to simulate a removed battery (press and hold the pin in position).
  4. Press and hold the power button for 20 to 30 seconds to release the residual charge from the laptop. Blowing compressed air into all holes and ports on your laptop might help to remove charged dust particles.
  5. Reconnect the AC Adapter.
  6. Once the system is powered on and booted properly, re-seat the battery. Check if you still get the error or not.

Method 8: Reset BIOS to default settings

If the problem is related to the firmware settings, you can reset the BIOS by:

  1. Shut down your PC
  2. Press the power button and immediately press F2 or F10 to enter the BIOS
  3. Press F9 to load the defaults, press F10 to accept changes or exit while saving changes. You can alternatively exit with defaults.

You can also try updating your BIOS since this controls charging too. You can find our guides on this here.

Method 9: Uninstall and reinstall your ACPI-Compliant Control Method battery drivers

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.

  1. With your AC charger plugged in, Press Windows + R to open Run
  2. Type devmgmt.msc and hit enter to open device manager
  3. Expand the Batteries category.
  4. Under the Batteries category, right-click the ‘Microsoft ACPI Compliant Control Method Battery’ listing, and select ‘Uninstall’.

WARNING: Do not remove the Microsoft AC Adapter driver or any other ACPI compliant driver.

  1. Confirm that you want to uninstall the driver
  2. Remove your battery, wait around 10 seconds and then plug it back in.
  3. On the Device Manager toolbar, click ‘Scan for hardware changes’ or, go to Action > ‘Scan for hardware changes’. Your computer will find your battery and reinstall your drivers (this might take a while). You might need to restart your PC and check if your battery is now charging.

Try disabling then enabling your drivers in step 4 above instead of uninstalling.

Method 10: Update your ACPI-Compliant Control Method battery drivers

Updating drivers will install newer drivers that are compatible with your OS. You can search for drivers from your manufacturer or:

  1. Press Windows + R to open Run
  2. Skriv devmgmt.msc og trykk enter for å åpne enhetsbehandling
  3. Utvid batterikategorien.
  4. Under kategorien Batterier, høyreklikk på listen 'Microsoft ACPI-kompatibel kontrollmetode batteri' og velg 'Oppdater programvaredriver'.
  5. Med en aktiv internettforbindelse, klikk på “Søk automatisk etter oppdatert driverprogramvare” i neste vindu. La PC-en søke etter en oppdatering og installere den automatisk på datamaskinen din.

Du kan også prøve å oppdatere BIOS. Du finner guidene våre om dette her.

Metode 11: Få en ny lader eller et nytt batteri

De fleste bærbare datamaskiner lar deg kontrollere helsen til batteriet ditt fra BIOS-avanserte-fanen. De kan også fortelle deg om laderen din er identifiserbar. Bare trykk F2 eller F10 under oppstart for å gå inn i BIOS; Du finner informasjon om batteri og lader i kategorien "system" eller "avansert". Hvis laderen er ukjent eller uidentifiserbar eller angitt som feil lader, kan det hende du må bytte den. Hvis batteriet er indikert som "sviktet" eller har dårlig helse, kan det hende du også må bytte det ut.

Hvis du er helt sikker på at laderen og batteriet er i god stand og er de riktige for den bærbare datamaskinen, vil du kanskje sjekke ut ladesystemet på hovedkortet.

Tips: Batterier trenger vanligvis utskifting etter 3-7 år. Batteriet bør oppbevares med 50% når det ikke brukes i lang tid for å forlenge batteriets levetid. Det bør heller ikke dreneres til 0% ofte. Oppretthold en god ladesyklus for å gi batteriet lengre levetid. Hvis den bærbare datamaskinen din ikke har et intelligent ladesystem, må du ikke la den være koblet til hele tiden. La batteriet tømme litt før du lader det igjen til 100% for å forlenge levetiden. Ikke la datamaskinen eller batteriet overopphetes, spesielt når du spiller spill eller kjører programvare som trenger mye strøm.

Kjør en batteritest av HP: åpne HP Support Assistant -> Feilsøking -> Power, Thermal and Mechanical . I kategorien Strøm klikker du på Batterikontroll . Hvis du ikke får pass eller OK på batterikontrollen, kan du kontakte HP Total Care for garantiservice.
