Check to make sure the power cord is firmly in place in the power adapter. The power cord sometimes loses contact with the receptacle in the power adapter.

When you’ve found that your laptop battery is plugged in but not charging, one of the first troubleshooting steps is to check your hardware faulty and make sure the hardware components work properly.

  1. Make sure that you power cable is not damaged. If the cable is not working, you won’t be able to charge.
  2. A bad AC adapter may cause your battery charging issue even if you’ve plugged in your battery. So you can try another AC adapter and see if it makes changes.

If your Lenovo is not charging even plugged in, you can also try power resetting your laptop, and this method works for many people who have the same issue. Here’s what you need to do:

  1. Shut down your laptop.
  2. Unplug your charger (power cable).
  3. Remove the battery from your laptop.
  4. Press and hold the power button for 30 seconds, then release it.
  5. Put your battery back in and plug your charger into your laptop.
  6. Turn on your computer, and it should start charging now.

A missing or outdated battery driver in your Lenovo can also cause the “plugged in not charging” issue. So you should make sure that your battery driver is up to date, and update it if it’s not.

You can go to the manufacturer’s website, and download and install the latest version of your battery driver.

Remove the battery and the AC adapter (charger). Press and hold the power button for 3 - 4 seconds with these removed. Pop your battery back in, along with the AC adapter. If it still refuses to charge, you could be looking at a bad battery or possibly a bad charging circuit on the motherboard.

I took my x230 apart, checking the small yellow AC connector for the adapter, plugged in several times in confusion and looking bamboozled at the orange

battery (which is the original btw) LED.

How in god's name does one come to get to know something like that, which isn't even mentioned in the manual.

I'm a happy x230 customer but that lock is bizarre and just effin stupid

Live long and prosper,

Greetings from Germany


Does anyone know what process the comment from hyphenpoint is talking about? It does not seem like he is talking about the process mentioned in the answer above but sounds interesting and I can't figure out what they mean and what they did.

You took the computer apart and then what did you check on the small yellow adapter? What lock did you find? How did you unlock it? Maybe I'm misunderstanding the comment but it sounds like they are talking about something different than any of the other solutions but I cannot figure out what lock he unlocked after taking apart the computer.

Any thoughts?

If you're having problems with the battery life of your laptop, you might want to check out the control panel. Generally, the battery charging icon will have a red X in the center. Sometimes laptop battery won’t charge even plugged in and the red X is also in the center, the problem is most likely related to the power cord. You can fix this problem by shutting down your laptop and restarting it. If these steps don't work, you should contact your laptop manufacturer for assistance.

If you've tried resetting your laptop to factory settings, it may have messed up the battery. If this is the case, try removing the battery and resetting it. A new battery may fix the problem, but you're better off trying to find a solution than spending hundreds of dollars on a laptop repair. A better approach is to troubleshoot the issue from the inside out, and then try to identify the source of the problem.

If you've tried all the steps above, but still no luck, your laptop's battery may be dead. It's best to replace the battery as soon as possible, but you can always replace it if the problem persists. If you've tried everything else and still have trouble, try using a portable charger. These devices will work in any kind of situation. If they don't fix the problem, you should contact a computer repair center immediately.

If you've tried these steps and still have troubleshooting to no avail, you should get a new battery. Sometimes the battery itself is the culprit. A damaged or defective power socket or adapter can damage the circuit on the motherboard. Changing the power cord and the battery will resolve the problem. The battery will have to be replaced if it doesn't work. However, if you've followed all these steps, your battery is still dead.

The problem is most likely the battery. Clean the battery compartment and remove any foreign matter. The battery should be inserted properly and the contacts should line up correctly. If the battery doesn't charge, replace it. Otherwise, you'll have to purchase a new laptop. You can try the troubleshooting steps again. If you're still not successful, you may need to contact an electrician. You can try the steps above in case your battery is dead.

The problem could also be the battery. You should check the battery compartment and make sure that it's clean and free of any foreign material. If the battery is dead, it might be due to an improperly installed power adapter or a faulty battery driver. If the battery is still dead, you should replace it. You can try removing it. If it still won't charge, you should try the steps above and try a new power adapter.

I work at a school - we have a bunch of Lenovo A485. Many of them not charging. The solution this time was.

  1. Turn on laptop while battery and charger was connected.
  2. Login to OS
  3. Unplug battery while laptop turn on with charger connected.
  4. Wait a few secs. (15 aprox.)
  5. Connect battery again.
  6. Confirm that laptop is charging or repeat from step 1. Usually works in first try.

Good day to all

Usually this is due to bad charging circuit in Thinkpad.

If you have a meter, remove the battery and you will see a set of connector from Thinkpad to battery.

The first 2 slightly longer connector pins is Negative. The next 3, you should get 3.3v when power adapter is plugged. If one of them is missing, your battery would not charge.

The battery pack of x230 is wired in 3 groups. Each is charge via the 3.3v supply via the connector.

If this voltage or part of them is missing. Battery will not charge or return to full charge. You will need to have the main board serviced. Usually this is due to one or more MosFET chip or fuse on the board go defective.


@cscs1956 On 2020 i had a similar problem, the middle pin was giving no voltage, but recently it started giving a voltage, and the battery started working but now it has again stopped.i am not sure what the voltage from middle pin was when the battery started working again, but currently it is giving 1V (but my meter is not accurate, soo....)


What could be the problem/ solution if 9ne if the pins is not giving 3.3v?

I want to add one more way here by which your laptop battery won’t charge. You should apply it and check whether it’s charging now or not.

Minimize the resources use:

Running apps and software keep draining the battery of the laptop. Your laptop battery won’t charge In case of apps are consuming power more than charging. Might be possible your charger is charging the laptop and the battery is also working, but consumption is high. In that case, apply the below steps to fix the issue:

  • Open the windows process taskbar by tapping Ctrl + Shift + Esc.
  • Find the list of programs from the window open.
  • Right-click on the programs and click end process which one consuming high CPU and memory.
  • Also, uninstall the not useful software from the PC.

You can change some more settings like power management and stop windows features. To know about their steps open fix Windows 10 laptop not charging issue. The article written here is my own and contains detailed information.

Laptop not charging usually is charging circuit or battery has problem. Next to suspect is under wattage charger.

As laptop charging circuit and supply circuit to CPU, or GPU is separated. They should not affect each other.

What worked for me for a while:

  • Turn the laptop on with charger plugged in (or plug it after the next step)
  • Login to the OS
  • Close the laptop
  • Open it
  • Now, it should detect you have it plugged in

It worked like a charm for a few weeks, now the battery doesn’t seem to work properly. But hopefully it may help someone.

The battery health information is stored in a chip installed in the battery assembly, not the laptop.

Unless you have access to some engineering program. You cannot factory reset this battery health information. Same even you reinstall the OS.

Some laptop eg ThinkPad has power management utility which allow you to recalibrate the battery status. This is simply by discharging then charge the battery again so the chip will measure the actual battery capacity again. This does not reset the battery charging cycle count and more then often, you will find after calibration, the new capacity reading will be lower then before or reflect battery as defective.

I discovered that it has to be powered on in order for it to charge HTH.

Well I will suggest you to check all power connections, and remove any power strips and surge protectors to connect the AC adapter directly to the AC power outlet. And also Check for any physical damage to the adapter, cables, and plugs, and ensure the power cable is properly attached to the adapter brick and the system.
