I have an hp pavilion dv9350ea. Over a couple of years the battery became defective and I installed a new one. It showed 30% charge. I disconnected the charger to discharge the battery before re-charging it. After a while the computer went off, and I re-inserted the charge lead. The icon says "0%, plugged in, charging", but the icon does not show the battery level being charged (although removing the lead for a second and replacing it runs the icon through four (increase charge" cycles - around 8 seconds before the charge motion stops), and the battery is not charging at all - even when left overnight! When the power lead is removed, the battery powers the computer for around 1 minute before it dies out. Please help!

I already thought of that one myself, but what clarification do you need? If it is indeed the new HP battery, then there must be a way of proving or confirming it.

As you can see in the write-up, I installed the new battery, and it went up from 25% to 30% max in the computer. (First step of re-calibration) I removed the charger lead and it discharged slowly until the computer closed down. (second step) That is as far in the re-calibration process I got. Now the battery does not charge as explained above.

When I normally look at a problem, I define ways to apply specific tests to prove the location of the fault or problem. Following this analysis, I devise ways to correct that fault. That is what I was hoping for from this forum.
In the event, I did the following: -
1) Check the battery in another computer for charging. It did!
2) I charged it to 10% in order to overcome any discrepancies in the low voltage charging inhibition between computers and attempted a re-charge again on my own computer. Result - about 1-2% increase in charge in the battery indicated before cutout of charge again. By this method of removal and replacement of the battery it now stands at 26% charged and rising slowly as re-booting etc takes place.
3) I then referred to the HP website, and learned that I may have a problem with corrupt software in the charging circuit somewhere, and I ought to re-install Vista on a clean disk to ascertain whether or not that is the problem. if it is, then at that stage it will be solved.
Any comments please?
