LENOVO ERROR BATTERY NOT INSTALLED

[FRITZINC]

FRITZM: I HAVE A LENOVO T410s LAPTOP AND OUT OF NOWHERE I GOT THE MESSAGE "BATTERY NOT INSTALLED." I WAS USING THE LAPTOP EARLIER IN THE DAY ON BATTERY POWER FOR ABOUT ONE HOUR WITH NO PROBLEMS. WHEN I GOT HOME AND PLUGGED IN THE AC ADAPTER I WAS WORKING AND THAT ERROR MESSAGE JUST POPPD UP. THE COMPUTER IS NINE MONTHS OLD AND HAS AN ACCESSORY BAY BATTERYINSTALLED AS WELL. LENOVO IS NO HELP ABD THE ANSWERS FROM THE IBM WEBSITE IS IN A LANGUAGE I DON'T UNDERSTAND AS IT REFERS TO VARIOUS DLL'S AND OTHER THINGS. WHAT IS THE LAYMAN'S ANSWER?

First, turn the CAPS LOCK off.
Second, remove the accessory battery and try rebooting with the original battery only.
