#1- Try a full reset

Unplug the power from the charging base, then remove the battery and let both the battery and power adapter stay unplugged for 10 seconds. After 10 seconds re-plug both back in and you should now see the charging base start flashing green again under the battery light.

That’s it! Your battery should now be charging again.

#3- The charging contacts could be bent

On the charging base where your headset charges is copper charging contacts. If these are bent at all your Plantronics CS540 will most likely stop charging. Try taking some pliers to bend the contacts back in place and see if this fixes it.
