Laptop disconfigurated, prolly numblock

Oi! Mom's laptop. Hp Windows 7, basically a cat tap danced on the keyboard and from what ive gathered its a numbbloq problem. Issue is, ive tried around 5 of the solutions and its still not fixed, fn+bloqnum, fn on the osk, uninstalling, ticking off sticky keys etc and taking out the battery. Its a laptop for work too so- and it does have a separate side for the numbers. Specifically the keys that arent working are y(+*y) u(i+u) i (same) h(/) j and k (kj) n(N and enter) m(,m) On the numpad 9 makes n an enter, when bloqnum activated makes the same but adds 9, 6 does the +*y thing and 3 or fn make <6. Thanks for reading and any help is greatly appreciated
