1) budget - 35 thousands rupees
2) mainstream - 15"-16" screeen
3) for normal purpose such as internet surfing, sending receiving mails, watching movies and that's it.
4) configuration should be i5, 500 GB hard disk, 2 GB graphics card and 4 GB RAM
Brands - priority to HP, Lenovo and dell
Screen resolution should be full HD.
Battery backup should be normal..
Purchase place- depend on best price. And country - obviously India.

you want FHD at 35k
lenovo Z50 is your best catch. Its possible to get it around 35k in exchange of course. 40k without exchange.

NEVER buy a normal 768p screen laptop when you have option of FHD one at the same price.

buy this Error 500 Server Error
lacks dGPU

But should be enough for @OP's needs
IMO still get the FHD one with 820m. (atleast some games will run on it)
