Keyboard Issues

[Sweet_Feet]

I've been using a standard laptop kb for almost a year now but I seem to be dropping a lot of notes lately (misses or goods) and it's getting really frustrating when I'm in the middle of a good run. The problem happens at random.. difficulty of the song doesn't necessarily matter (see replays below) but the keyboard tends to drop notes more often on denser songs.

Here's a couple replays if you don't get what I mean by dropping notes. I don't really care about these songs in particular since I just start over and usually get the AAA but I did miss out on oni about a week an a half ago because of this problem.

I'm looking for any kind of suggestions and wondering if it's because my kb is fried or if it's my key set-up that still needs to be worked in (ERUI.. getting on to 2 weeks now).
