I also have an Aspire v3771g, but I am experiencing these problems with the 9, o, p, l, ;, and . keys. It was intermittent at first, but after searching online and finding others with the same problem (maybe with different keys, but the same intermittent key operation), I noticed that some people said that their keys became functional after moving the laptop. So, putting it to the test, when my keys wouldn't work, I lifted and rotated my laptop around and what do you know, they started working again. I called customer support and they walked me through uninstalling and reinstalling the keyboard drivers, but that didn't help at all. They also walked me through a power drain test, which was equally useless. I have a USB keyboard that works fine with no problems, so, based on the information gathered from tech sites and other forums, it seems that the keyboard itself is at fault. Even after learning this, I'm having a hard time sending my computer to Texas to have the repairs done with an average turnaround time of 3-4 weeks and paying shipping charges, so Im looking into replacing the keyboard myself (which I've found online for around $30 USD) with a little Youtube help or, possibly, buying the keyboard and walking into a computer repair facility to have the replacement done within a few days.
