You can test the battery: Open an Administrator CMD prompt (CMD, run as Administrator).Paste this command, and then press Enter:powercfg /batteryreport That will show a figure for the designed battery capacity (when new) and the current ("full charge") capacity. Your laptop is five years old. If that is the original battery, it is near end of life and failing. It may also be swelling, which can cause touchpad and keyboard issues. I recommend that you open the laptop to check the battery. If it is swelling even a little, you must remove it and safely dispose of it. Please do not throw the battery in the garbage. Take it somewhere that it will be properly disposed of. In many places, stores such as Best Buy and Staples will accept old "tech" for proper disposal/recycling. A recycling depot may also accept batteries. These links should be helpful to you: Swollen Battery Information and Guidance | Dell Canada How Do I Recycle or Dispose of My Dell Battery | Dell US Whenever touching components or working inside a computer, wear a grounded wrist strap, also called anti-static wrist strap, ESD wrist strap, or ground bracelet. It's a cheap and sensible precaution. Rest the laptop on an anti-static mat or at least a reasonable alternative such as corrugated cardboard. (Repeatedly touching a metal case part is not sufficient mitigation with modern components.)
When i connect the charger without battery the laptop is working normal. But when connect the battery & plug in also that time orang light continually blinking. And when plug out (Only use battery ) the laptop is shut down
