Buying Laptop - Need advice

I am working as an SAP Developer. Been using company laptop for every thing for quite long now. Now I want to buy a personal laptop to:

• Store multimedia content offline
• use Obsidian for notes
• simply watching video/movie etc
• maintaining Kindle books library
• if in any rare case, office laptop stops working, would like to install SAP GUI or some IDE on it to resume with temporarily.

So basically I'm looking for a laptop that has a good battery life, good memory storage, doesn't have to be the best at performance (not much of a gamer, if basic games work that's enough), good service at Hyderabad, future proof (it doesn't get 'outdated' too soon), with a budget not more than 40-50k.

Please suggest.
