When I plug the charger to the laptop, it doesn’t charge, while it is turned on. Though it does charge when, the laptop is turned off (I know this from the LED indicator on the computer). I thought the problem might have been from the charger cable because there was a little plastic piece that had snaped off. This might have caused a bridging between plus and minus.

I then changed the cable on the charger by soldering on a new one. This didn’t help. I borrowed a multimeter from a friend to check if the port in the laptop was getting the right voltage, which it does. It might be important to ad that before I changed the cable on the charger. I was sometimes able to charge it while turned on, if I moved the cable a bit. Though this was quite a while ago, because I haven’t the laptop for a long time. Is there anything else I can do to maybe fix it?

Hi, Create a Win 10 battery report to check the status of the battery. Compare the Design Capacity to the Full Charge Capacity values in the report. If there is a big difference it may be that the battery is failing and the charger cannot do both, i.e. run the laptop and charge the battery at the same time. Update (01/14/2021) Hi @Rasmus Lorenzen The battery is only at 72% effectiveness when fully charged but I would have thought that even at this value it should be able to start the laptop without the charger connected, unless it is faulty and cannot handle the load. Since you have changed the charger cable and measured the voltage at the input to the laptop the only way to tell now is to replace the battery as then you will know that you are using a known good battery. Here’s the hardware maintenance manual for the laptop. Go to p.36-37 to view the necessary pre-requisite steps and then the procedure to remove/replace the battery pack. On p.91 Item #14 you will find the part number for the battery. Search online using only the part number appropriate to your particular model variant to find suppliers of the part.

Did you uninstall the battery and reinstall it in Device manager with the latest drivers after you changed it?
