If it was the battery it should boot with the charger connecter still if its not its most likely the adapter. You can try getting a universal laptop connecter at walmart for cheap and try that
Not possible for that price range you are looking at the cheapest laptops out pretty much the best you will get with those games is about 30-40 fps on medium with a 500$ laptop. If you can only spend that much your best bet is to build a 500$ desktop
Any entry level laptop will meet those needs just look at any laptop in your price range and you cant go wrong . Just so you know its not called a cpu its called a PC(personal computer) a CPU is a central processing unit.
Do you work for google? Chrome os in every way is worse then windows its a no brainer if cost is the same. With windows no matter what program or anything you decide to do you will be able to do it. With chrome os you are extremely limited its not worth it

Sounds like your battery died from impact, your only solution is to replace it which roughly costs about 80-120$ depending on the battery. Look up your model of laptop with the keywords replacement battery and buy what's cheapest
lenovo have a way better build quality than Hp. If you have to pick between Hp or lenovo pick lenovo hands down. Go for the best specced lenovo laptop you can afford you wont be disapointed
For league of legends it'll be fine any other game not so much. Its best to stay away from u version CPUs they are low powered CPUs meaning lowered performance and the 840m isn't a mobile gaming graphics card really its more for streaming and movies and such, its better than integrated but not great
