I reviewed your post and I understand that the battery is not getting charged completely and the light beside the charger is blinking.
Don’t worry, I assure you I will try my best to get this sorted.
What is the product number of your computer?
If the light beside the charger is blinking it means that the battery is not working correctly. I recommend you update the BIOS from the below link and check whether the issue is resolved.

If you continue facing the issue, then reinstalled Microsoft ACPI-Compliant Control Method Battery under device manager.
Here is how you do it.
Step 1: Click the Windows “Start” button and right-click “Computer.”
Step 2: Click “Manage,” then “Device Manager.”
Step 3: Click the “Batteries” section. A list of devices will appear.
Step 4: Right-click the “Microsoft ACPI-Compliant Control Method Battery” device and click “Uninstall.”
Step 5: Click the “Action” menu item and “Scan for Hardware Changes” to reinstall the driver.
Restart the computer and the issue should be fixed.
Let me know how it goes and you have a great day!
