What do I need to do before LWD at Infosys?

My LWD is on 17th Jan. What are the procedures I need to complete before it (like i have recieved the mail to submit ID card on LWD, but nothing on returning the laptop, charger and mouse)?

Also what activites should I absolutely keep in mind before leaving (like do i need to get any clearance certificates or any other documents)?

I have already downloaded the payslips. Should I also get the experience letter?

Please advice the best practice and absolute necessary things I should do (i dont have any job lined up yet, so do i need to take care of anything else like EPF or something else)?

I dont know, please help.
