Acer aspire 5733 on booting makes beep sound on booting-RESOLVED

My laptop on booting makes continous beep sound and after 1 min it starts normally without showing any error message.

Update (07/22/2020)

Problem solved. Problem is with the keyboard. One of the key was short and on booting it creates beeping sound. After changing keyboard everything works fine.

Try taking out the battery and just use the power supply.

Does beep go away?
