I’d suggest that you follow the steps mentioned below and check if the beep pattern repeats.
Switch off the computer.
Disconnect the AC adapter from the system.
Remove the battery from the computer.
Press and hold down the power button for 15 seconds.
Then connect back all the peripherals and check if the beep pattern repeats and reply us with the beep count.
5 Beeps on the system means’ Real Time Clock (RTC) power fail’ and the cause of the issue is ‘CMOS battery failure’. I’d suggest that you update BIOS and chipset driver on your computer to check for issue resolution. Please enter your service tag # on the link below, then download the BIOS from BIOS section and chipset from chipset section onto the system and install it.

5 beeps means a weak or missing reserve (CMOS) battery, or a faulty CMOS clock chip.
Replace the coin cell battery.
