Windows 7: Battery Fully Charged turns off AC

Battery Fully Charged turns off AC

This problem started 3 weeks ago.

When battery charge reaches 100% the AC LED indicator is turned off and the laptop runs from battery (decreasing it's performance even selecting High Performance power plan).
If the AC plug is disconnected and reconnected the AC LED indicator is turned on until battery is fully charged again, as soon as the battery is fully charged windows battery notification icon changes from "99% available (plugged in, charging)" to "Fully Charged" and then the AC is turned off and the laptop starts to run from battery again.

I didn't update any laptop specific software nor BIOS.

Does anyone know how to fix this? I want the laptop to run from AC when AC is plugged in, even if the battery is fully charged.

Thanks!

If there is not a setting in the advanced power settings, pull the battery out when not using it mobile...my laptop battery stays charged and on the shelf...

That is not ideal because I need to use the laptop on battery very often. Besides that was not happening before.
