Read the op post wuji... Op doesnt want to play games on it, just watch videos and do some non-computational heavy hw
No games - then look to get a better cpu ram and ssd at the cost of weaker gpu, perhaps integrated cpu-gpu. Get it big and thicc, don't go with touch screen - that's crap, basically the bigger it is the easier to get work done. Who cares if a notebook or something is 1kg lighter than a normal laptop, that hardly matters, get the real thing. You say you won't use it for games but what will be your assignments? If they are coding or using engineering programs that calculate aerodynamics of a model or something you might as well get a gaming laptop equivalent. Those programs are more resource hungry than games.
Huawei mate 10 phone would work as a "computer" Hook up Bluetooth keyboard/mouse and wire/wireless projection to a monitor, 3.5 jack for speaker hookup Then take the phone with you when you go outside It's basically a "chrome book" without the book part of it, specs of the phone similar to chrome book too Since it is last years model, the price has come down on it too
Get a used Dell Precision Mxxx from eBay with dedicated graphics and 16 gbs of ram running on powerful i7 cores. Some sellers even do a 1 year warranty for the laptop. You really can't go wrong with these refurbished systems. Great for video editing, graphics, 3d cad, and power computing (50+ tabs open at once).
HP with next parameters: i5 or i7; 8 gb ram or more 500 hdd with 128 ssd or above or just ssd with 256gb or above
At that price range you can get a brand new i3 or 2nd hand i5. If you can find and IPS panel display then it would be better for your eyes since you will use it for studying. Less eye strain
Laptops for students usually have pretty good specs and an affordable price. if you can snag one with i5 or i7 core and 4gb ram, it's good enough for your purpose. you can still run photoshop pretty nicely and play some games. nothing too heavy, just nice.
