nothing to hide here...these are customs' rules. basically, you can't have 2 laptops on you. i can't say if customs changed the rule in last 10 months. even if you get your work laptop registered (don't know the exact term) with customs before leaving india, their rule of no-two-laptops while returning to india still holds true. they did this to me twice.
i had stamped my work laptop with customs on 1st occasion and while coming back i proudly said yes, "i am carrying 2 laptops", when they enquired me. after a little argument, they pulled out the printout and brought in higher ranking officials. i felt cheated because i took the pains to declare my work laptop beforehand. anyways, i asked them to keep my work laptop and let me go with the new one

. but they wanted money. i don't think they were indicating bribes. after a lot of argument in polite english from both the sides, they let me go without any charges. they didn't touch any of my baggage, which was full of goodies.
15 days later, on my way out, i never bothered to do any formalities regarding my work laptop. after 3 months, i came back with 3 laptops (2 work + 1 for a friend). they asked me again and i said i wasn't carrying anything dutiable. basically, nothing belonged to me so i was ready to let them confiscate my stuff. i was allowed to go without any further checking.
they caught me once more on another occasion and because i was already pissed off due to several issues during the journey, i asked them to talk to my dad. i had already told them that i had 2 laptops but they let me go without any asking anything else.
on rest of the occasions, i had less electronics but loads of bodybuilding stuff. protein powders, light weight gym equipment etc. they scanned the stuff, made me eat the powders as well but couldn't figure out what to do next, so they let me go.
following things helped me:
1) talking to them respectfully. they are just doing their job.
2) late night flights. my flights used to land after midnight. this was to ensure next day off in india

. i found customs officials sleepy and tired during this time. that helped a lot in my arguments with them.
3) to look like an idiot or student

i was caught only those times when i was dressed/looked like a software professional.
this is an excerpt from
www.cbec.gov.in/trvler-guide_ason22may2013.pdf, a printout of which was shown to me:
One laptop computer (notebook computer) over and above the said free allowances mentioned above is also allowed duty free if imported by any passenger of the age of 18 years and above.
according to customs officials, this rule mentions one laptop, so it has to be one. of all the text printed on that paper, only this line was highlighted.
