I know you said you don't want any discussions around pricing in your FS thread but I couldn't resist.
Ain't nobody here gonna shell out 1.5lac for a 2nd hand laptop
specially when similar specs to yours can be had for 1.6lac aside from ram. And 64gb being as useless to the vast majority it is and being cheap af.
And I'm not even gonna get into your lack of invoice for the laptop which makes warranty claims outright impossible, Anyone who has the kind of money to shell out 1.5lacs for a laptop and are present here would have done their research and would know just how hard it is to maintain gaming laptops and pretty much how essential warranty is.
you said your laptop is 1 month old in your original post and now it's more than 2 months old, you have a fast depreciating asset and the more you don't sell it, the more it's value drops and your chances of actually selling it for decent money.
Now, ending this, you have two options:
1. Drop the price aggressively and hope someone buys it from you (highly unlikely unless you go 1L or below)
2. Just use it yourself personally and just not sell it or sell to someone in tour family for a deep discount since you anyways would need to drop price a lot (which is what I would done and did when I wanted to sell my 2 week old s23)
