Battery 0% available - not charging

[John_Fraser]

Greetings -

I have an HP Pavillion dv 6500. I am having a similar battery issue that has been discussed in other posts. The original battery "died" a couple of Months ago, and I purchased a new one from HP.

Now the icon in the System Tray shows "0 % available (Plugged in, not charging)". I installed the HP Support Assistant, and ran the Battery Test, The result was: Status: "Calibrate" and Current State: "Unknown".

Problem is that part of the "Calibrate" procedure is to allow the Battery to charge-up (to 99 to 100% charge), but I am unable to accomplish that, since the battery is not charging - the charge remains at 0 %, and never seems to charge.

Am I missing something? Any suggestions from the Forum will be appreciated !
