Our HP laptop's battery keeps losing power from the battery. The fully charged icon on the bottom right of computer was showing it going down, down & down, then message said to plug in the power cord. We changed where it was plugged in the power strip and into different wall outlets, still the same. So, we purchased a new battery and after one day and evening, the same thing happened with the newly installed battery. Is the computer shot and/or what! Does anyone know what we can do, or is nothing we can do??
