New Battery for R51 Not Charging

[D-Man]

I picked up a new battery for my R51 - it's the Panasonic version 92P1091.

When I put it in, the battery indicator turns orange and flashes. I left it in overnight, and still have 0% charge in it.

The older batter still does charge, so I know that the laptop itself seems to be working properly.

Any ideas?

Edited to add the Battery MaxiMiser doesn't seem to even recognize the battery (says Error).

Well after about 20 times of putting the new battery in and taking it out trying to get things to work......the battery light stayed orange, and it is finally charging.

I'd guess it was the battery, as the older battery always would show up and charge when inserted, but since it's working, I'm not going to worry about it.

There is a bug "Battery sometimes does not charge" in older R51 Embedded Controller firmware. Updating to the latest one (together with new BIOS) has solved it for me.
