windows 7 - Dell Vostro 3560: 3NB8W3 battery not recognized, problems with charging

I've been using standard battery for a while, but finally I bought extended battery (3NB8W3, 11.1v 8700mAh 97Wh). Sadly, my Vostro 3560 does not recognize battery properly.

I always have "Plugged in and charging" icon in tray when I plug power adapter. When I unplug it, I get empty battery icon without information about power level.

Besides that battery works fine (about 4-5h), but:

• It is not charging when I plug in power adapter when computer is suspended (charging icon suggests it's charging, but it's not, at least not always)


• when it's completely discharged I have to plug in power adapter (while I'm logged in to Windows), then remove battery and install it again; then repeat this again later because it will only charge about 50% without it

I did what I found about ACPI driver (uninstall, restart computer etc), but it does not work. BIOS updated to latest version.

I have tried resetting like here but it did not work too.

Any suggestions?
