Hi, I am suffering the same symptoms with my new battery.

I have a Compaq Presario 900US and one day while working on battery, the computer suddenly entered on hibernation to save battery when it was supposed to be almost full. After this, the battery did not charge anymore and the LED just blinked red the whole time, with the meter stuck at 99%.
I was told it was the battery (even though it was barely one year old), and after a long time of using the laptop without battery, I decided to buy another one. I couldn't find one like the original of 14.8 V, but in many places 14.4V ones were listed as compatible with my model, so I tried one of them.
The symptoms were similar to AndyA's, except that after the minute of solid light and blinking, the LED turned off altogether. Unlike AndyA, I never got the battery to charge to the point where I could plug the computer off and not lose energy, although perhaps I wasn't patient enough.
Yesterday, I had the battery changed for another one (still 14.4 V), but less capacity (3.2 AHr, not 4 AHr as the original) and it still can't charge. If I try to charge it while the computer is off, the same thing as AndyA happens, but if the computer is on or on standby, the LED stays on with the solid red light, however, even after leaving it overnight, it still has no charge.
On the other hand, the laptop has no problem running with an already charged battery and I think it is even able to charge a partially charged one, since I saw the meter go up one percent or two after plugging it in for a while.
Is it more probable that my charging circuit is defective or that I just had the bad luck of getting two defective batteries in a row? If it's the former, does anybody know about how much would the repair cost?
Thank you.
