New thrift sore pickup wont stop beeping at me while on

(Stock reference image because im terrible at taking pictures)

I got this dell laptop for 10 dollars at a thrift store and it powers on but i beeps 5 times at me before reaping the beeps. I oped up the laptop to give it a light clean but to notice this model has the storage and ram embedded into he board. I took a gamble with this laptop, im thinking the cmos batters need replacing but im unsure. What would you advise? This is a dell inspiration 11 3000 series from 2010.
