Battery cannot be determined

Hi,

Can someone help me? Have a Dell laptop-Inspiron N5030. Running Win7 home prem. Having battery cannot be determined or charged issues. 

Sometimes on boot up I receive the message "battery cannot be determined" and it says press F1 to continue, F2 for setup, or F5 for diagnostics. 

I've gone into setup to check the battery information. States battery life is at 0%, battery health says its not a Dell battery. But the battery came with the Dell laptop and is original.

Sometime it makes through the boot process and when Windows boots to the desktop I get the error message "The model number for primary battery cannot be determined. This will prevent any battery present from recharging. Please insert a Dell laptop battery, blah, blah blah.

I've tried to update the bios, but it won't let me. It states that the battery and AC adapter must be connected, or something similar to that. I also have a Dell Latitude laptop and tried swapping out my AC adapter and got the same error messages.

Is there something else I should be doing or does anyone have any recommendations? Sure would appreciate any help.

Thanks
