After a new battery in my Samsung notebookNP900X4C, the battery is 100% fully charged. If I remove the power adapter, the notebook turns off immediately - in the logbook: unexpected power failure. If the power adapter is plugged in, 0% is first reported (not connected to the charger), after a few minutes 100% fully charged. Where do I fix what?

Hi Lars,

If your battery is not charging, please use the below steps to fix the issue.

Step 1: Check the AC adapter and verify removable cord is fully inserted.
Make sure that the battery is properly seated in its compartment, and that there is nothing wrong with either the battery or laptop contact points. Finally, find out whether the problem doesn't lie with the laptop at all: Try plugging the power cord into a different outlet to see if you've got a short or a blown fuse.

Step 2: Check the Connector
When you plug in the laptop's power connector, the connection should be fairly solid. If it's suddenly wobbly or loose, or if the receiving socket gives when it should stay firm, the power jack may have broken inside the chassis. Are there discolorations or any sort of burning smell? If there seems to be any damage to the power connector, repairs will be in order.

Step 3: Check Your Settings
  1. In the Control Panel, open up the Power Options.
  2. Open the plan settings and visually check that all are properly set.
  3. Be on the lookout for incorrect settings for the battery, display, and sleep options.
  4. For example, your battery settings may cause trouble if you set the computer to shut down when the battery level drops too low or set the low battery level at too high a percentage.

You can also assign actions like sleep and shut down when your lid is closed or the power button is pressed.
If these settings have been changed, it's easy to suspect a power malfunction even though there's no physical problem with the battery or charging cable.
The easiest way to make sure that your settings aren't causing problems is to restore the power profile to default settings.

Step 4: Update Your Drivers
  1. Open the Device Manager.
  2. Under "Batteries" you should see three items, one for the battery, another for the charger, and a third listed as "Microsoft ACPI Compliant Control Method Battery".
  3. Open each item, which will bring up a Properties window. Under the "Driver" tab, you'll see a button labeled "Update Driver."
  4. Go through the driver update process for all three.
  5. Once the drivers are all up to date, reboot the laptop and plug it in again. If this doesn't resolve the problem, uninstall "Microsoft ACPI Compliant Control Method Battery" completely and reboot.

Step 5: If all the above steps are not working, then the battery is faulty and it needs to be replaced.

I hope this helps.
