The laptop I bought has served me for about 5 years. Now, Its at 9% and not charging. Whenever I unplug my laptop, it immediately shuts down. I went through many videos trying to fix this but nothing works for me. I can't even turn on my laptop without charging. My laptop is a Samsung R420. Its running Windows 10. Please answer as soon as possible as I have a project soon.



Please Help.
Thanks !


I didn't find the right solution from the internet.
