You can check by unscrewing the bottom of the laptop. I don't specifically know how to disassemble this model, but clicking on the device you listed you can see instructions on how to do it. For me, I usually unscrew all screws (there might be some under the rubber feet (The rubber strip under your laptop to keep it from sliding, yes they're called that) and make sure to find the gap. That's where you want to pry it open carefully.
Once you get the laptop opened, locate the ribbon cable for the keyboard or inspect the entire device for any damage.
***''Make sure to keep ALL screws separated and labeled in order to assure you put the laptop back properly.''***
You can search online for a new keyboard, or get a USB Keyboard and Mouse if you want to go that far. If you don't want to do that, I suppose downloading all of your data on a high capacity USB/SD Card and get a new computer.
Hope this helps!
