Laptop keyboard hardware problem or Virus?

OK, I did the error checking overnight. I didn't really see it to completion because it was getting late. Seems like it finished I'm assuming.
I don't know if I should replace it. Perhaps it's time for a NEW laptop anyway to be honest (my cdrom/burner drives are down/broken, there's a chipped corner of my laptop along with a few dozen scratches, my removable battery is drained/dead (2nd one dead now; I run straight from AC power) and now my keyboard has crapped up). Rarely is it a software problem oddly and the little replacements add up $$. It's been a good 5 years with this one. I'll wait until the end of the year/Christmas maybe and see how long I can take it with the USB keyboard. I have my eyes set on another Lenovo and their employee pricing events online are pretty decent.
Back to the problem at hand, maybe I'll take out the keyboard to take a look at it and do some cleaning. Usually I don't like taking things apart unless I have to. I'm ready to move on to the next step.

I can't determine if it's the keyboard itself that has gone bad or whether the software running it has gotten corrupt But from the description of the system, it sounds like you should consider putting pennies in a jar and when there are enough, replace the system. What is confusing is that the USB keyboard gets the right keys, so my 'guess' is that it's the hardware keyboard itself gone bad.

You could also look on the manufacturer's site for model number and get some idea of what replacement keyboard would cost. Or maybe even a used one would do. I'm sorry I can't help you more- I'm not a hardware person!.

no problems Bobbye! I'll take it apart this weekend to see what's up with it.
You mentioned a script a few posts back to take out some foistware? Will I need that still?

Yes, I can still write the script for you to run through Combofix. I'd rather wait until you have finished opening the system and checking- so let me know when that's done.

Just did the take apart last night with a buddy who knows more about hardware. She's not exactly sure what the cause is but she mentioned something about it looking slightly warped. When we took out the keyboard it was sort of bent up so something might have caused that to happen. We did a good clean and a diluted wipe down. The keyboard still does NOT work; everything is the same still. I've looked into replacing the keyboard through ebay. They're going for about 20$ a pop. Fair enough and hopefully it'll work. Regardless, I'm probably going to get a new one come September.

The warped keyboard isn't going to work. Trying to use it is only going to frustrate you. Do you have access to another computer you can use til Sept? And you could start backing up your files.

I've got a USB one I can use for now which is fine. I have a desktop I can use.
School term starts in September so I'll definitely need one for teaching purposes. I just ordered the keyboard part from ebay for 20$. It'll take about 15 business days. I'm waiting for the back-to-school sale in August before I get a new laptop.
I backed up everything before I took it apart to have a look (just in case it didn't turn back on)

Good decision! To commiserate with you: I ordered a Dell Mini last summer. Couldn't understand why I always had a line of ggggggggggg when I typed that key. So I started checking it out and realized it had no 'push' to it- so it didn't 'push' and release. That key is right smack in the middle of the keyboard- easy to hit partially. I ended up having Dell replace the entire keyboard! Wouldn't touch it until it was fixed.

I hope the new keyboard works out for you.
