Hello,

Given the age of this notebook (some six years old) it is likely the internal battery which backs up the BIOS settings to CMOS memory and powers the real time clock has failed. Dell has a manual here on their web site explaining how to replace the 'reserve' battery (some disassembly required), You can probably find a replacement reserve battery through your favorite search engine or price comparison shopping web site.

Regards,
