Battery light blinking red during charging

\015 Dell laptop battery light blinking red during charging and even if the battery is full.\015

Answers :

Dell or Panasonic? Your post has both listed.

If the blinking light on a Dell is yellow or amber or orange (somewhere in that color range) and continues to blink the entire time it is plugged into AC power (wall outlet) and when you unplug it from the wall the laptop immediately dies .... then you battery is dead and needs replaced.

If the blinking light stops after a while (perhaps a minute?) and then turns green while plugged into AC power, then it is successfully charging - or so it thinks.

When you unplug it from the wall, does it stay up and running?
If it runs, it's OK - just ignore the light and plan on getting a new battery one day, start browsing now. :)
If it dies immediately upon unplugging, then your battery is dead and needs replaced.
