Keyboard Not Working Properly

glenncarr74 · Sep 27, 2017

I have a keyboard issue on my Toshiba satellite. I have replaced the keyboard and did a system restore. I have tried all tips I could find online. The issue is when I press the a the cap lock comes on. When I press it off a capital a appears. When I press the x it places a symbol before it. When I use the m it switches places with the letter before it. I have reset bios. Did a hardware scan to find any changes, uninstall the keyboard and did updates. These are also the same issues I had with the other keyboard before replacing it. I also replaced the motherboard as well. I'm at a total loss.

have you checked to make sure the cable (or flexible PCB cable) is plugged in properly (and undamaged)? also make sure the connection and socket are clean.

I have. It has me really stumped.

I guess it's possible the keyboard controller failed. Other than that I haven't a clue.

Where would the keyboard controller be at

190221 · Sep 29, 2017

from https://en.wikipedia.org/wiki/Keyboard_controller_(computing)

Today the keyboard controller is either a unit inside a Super I/O device or is missing, having its keyboard and mouse functions handled by a USB controller and its role in controlling the A20 line handled by the chipset.

So it's on the motherboard, not replaceable, generally part of another chip but can still fail.
Your best bet is a clean reinstall of windows, or a new PC.
But since we're at it, does a USB keyboard work okay? better yet, does your laptop have a ps/2 port that you could try a keyboard in as well?
since you replaced the motherboard it may not be the KB controller, a reinstall of windows may do it.

If that's the case. Why would I still have the same problem when I got a different motherboard. I can use a USB keyboard and don't have a problem. I have put a good amount of money into this laptop to try and sell it. At this point I might be better off breaking it down and selling it in pieces on eBay.

Selling for parts is always an option. It probably isn't the mobo.
Try reinstalling windows if you can, otherwise burn a linux livecd of some sort to test the keyboard outside of windows.

I have reset it to factory and reinstalling windows. Where can I go to burn a Linux livecd

190221 · Sep 29, 2017

linux mint can be burnt to a dvd and booted off. the livecd functions as an OS, so it has several programs where you can type (to test the keyboard).
linuxmint.com
if the laptop is 64 bit download 64 bit otherwise get the 32 bit.
i would recommend the 'cinnamon' distro.
when you boot off the dvd you might get a prompt asking if you want to install linux mint. just say 'no' as you're only using this to test the keyboard.

to burn the iso to a DVD use a free program like IMGBurn: http://www.imgburn.com/
