If you can afford it, a small or medium ecoflow battery and one or two 200W solar panels with solve a ton of your issues in India, if nobody steals it. I'm in Africa and have frequent load shedding too, and I've replaced so many devices in my home with rechargeable/outdoor variants that can be recharged/powered by solar if needed.
Also, don't buy asus again. If you are looking for repairable laptops, dell, hp and lenovo are the only decent brands when it comes to repairs & parts (make sure the not to buy the cheapest consumer models).
If you want a fixed installation, EcoFlow products seem rather expensive. You look to pay a huge premium for the portability, which is actually less convenient than the traditional inverter design if you don’t need it. Simplifying things to a single number for their cheapest vaguely-comparable products, 1 kWh, LiFePO₄, solar-capable: EcoFlow Delta 3 1000 Air is ₹60,000, Livsol L-iON1500 is ₹27,500.
The only reason why I mentioned the brand, is because most of their battery systems have the yellow solar port - so you can plug solar directly into the system, some have two ports. They also have built-in inverters, so you can plug the laptop directly into that. There are probably other brands that offer a similar setup.
If your laptop can be powered by USB-C, even better. If the battery system doesn't have usb-c output, buy a GaN charger (mine is a 140W GaN charger and its amazing). They are super efficient and don't generate much heat.
Fixed-installs (or grid tie-in) requires electricians and sometimes rewiring some parts of your home's circuitry. Huge operation if done right but generally not needed if you only have one or two panels and a portable battery system.
There are very good benchmarks on youtube with the portable solar + battery setups.
