If the laptop charging light is blinking it could mean the battery is dead or the battery sensors need to be recalibrated.

1. Simple battery reinsertion: just shut down the laptop , remove charging cable, remove battery, if there is dust build up , remove it . Reinsert the battery And try booting it. Maybe it will work. Otherwise try next method.
2. Recalibration: Remove battery , connect charging cable , start the laptop. Once you are in search device manager -> batteries . you will see 3 names in the field opened like Microsoft acpi compatible battery and some other names. Select all 3 and one by one uninstall them. If it asks to restart simply ignore and shut down.(don't restart, I repeat.) Now insert the battery back and the charging cable and boot the laptop. You will see it working normally and charging light stops flickering. If this too doesn't work try next method.
3. Google battery health view by nirisoft and download it. Once downloaded , extract the .zip file and launch battery state view. You will see a lot of data ignore it and move down to column of designed capacity and current capacity and battery health. If battery health is below 30 ,it means battery is weak and needs replacement soon.
4. Try to check the charger for damage. Also check the charging socket on your laptop. Some laptop check if the charger is original and give problems if it isn't.
