Hmm. Well, I got an HP, and at least on the model I got, when the keyboard went, all I had to do was buy a replacement keyboard online and it was a fairly simple task to pull the current one out and replace it. Three screws under the battery and I was able to pop the old one out and the new one in, and it only cost me $20 online.
Of course, on my new laptop, there isn’t a removable keyboard, so...
But on the other hand, I wish I’d gotten a warranty on my FIRST laptop, way back when they were expensive. The screen blew out and it cost a good $600 to replace.
Where did you find keyboards online?
