That blink code indicates a bad battery and you will have to replace the battery. Taking out the battery, if for too long, can actually shorten the battery lifespan. Better to leave it in while connected to the adapter and periodically disconnect from the adapter and let the battery run down to about 50%. To check the battery health you can run diagnostics on the system. Restart the computer and at the Dell splash screen start tapping F12. Run system diagnostics paying attention to the adapter and battery results.
