Unplug the system, remove or disconnect the battery and hold the power button for 30 sec. Remove the reserve (CMOS) battery and replace it with a new one (if you need details, we'll need to know what system model you have -- i.e., Inspiron N5110, 5521, etc.).
Then power up and see if the error clears -- if not, replace the mainboard with a new one.
