Don't worry, no physical invoice needed. Warranty is linked with your laptop's serial number.
Although some parts may have different validity for warranty, like battery & charger may have maximum 1yr or 6months of Warranty
You can install Lenovo Vantage app from Windows Store, it will show Laptop's warranty details & Battery's warranty details in Power settings
Thanks for the information bro. Yes, have already installed the vantage app and it shows warranty period for both. 36 months onsite and 1 year carry in for laptop. For the battery it shows 3 years!! Don't know if that is to be true..
If you go to the Lenovo service centre's, they should most likely not need the invoice if the warranty already shows as active.
If they are asking you to activate the warranty with an invoice, that could be a different tricky situation.
I asked for the same but he said I will get the warranty and shouldn't worry, hence wanted to double confirm.

Where did you buy the laptop from?
OLX
I the seller is using any type of Account / invoicing software, he should be able to produce soft copy of invoice any time.
