HP Battery Pack won't charge.
I ordered this online. The cost was decent for an HP brand power pack for my laptop. Shipping was as promised, it arrived on time. I wasn't able to unbox for a week or so. No booklet with it and It won't charge. Its power source is c-cell. plus it has a usb and another c-cell port. I have even tried to charge with use of other ports. It also has a button to push to show you what level charge through a row of 4 small lights on the side. These lights flash when it is plugged in for charging, but one doesn't light up of the 4. No lights light up with the button. I plug into my laptop and there is no charge to laptop. It appears to be well made. I will return.
