Urgent advice Techm exit LWD

Today’s my last day at Tech Mahindra (early release). I’m returning my laptop and ID card, but I want to be super sure I don’t miss any crucial steps.

Can anyone tell me:

• After returning the laptop, should I get a confirmation email or acknowledgment from the asset team?
• Is there any form or sign-off needed from HR or my manager?
• Do I need to update anything in the timesheets or portal on my last day?
• Any tips to avoid delays in my F&F or relieving letter?

Would really appreciate some quick guidance from anyone who’s recently left TechM. Thanks!
