Keyboard Issue on a Toshiba Satellite c55t-c5300 Laptop

I am no longer able to type double letters/numbers or even use the backspace or arrow keys properly. If I try to type double letters (for example, the t's in letter), I have to either hit the space bar and then the backspace key to get the cursor back to the proper position after the first t to continue typing the next t or I have to arrow back to just before the first t that I typed so that it will allow me to type the second t then hit the END key to get the cursor back to the correct position to continue typing. (Hopefully that made sense!)

But the really strange, and frustrating, part about this is that this issue does not happen if I hold down the shift key while I type.

I have already tried the following in hopes of correcting this issue:
Adjust my key's typing delay speed - no change
Turn of my filter/sticky keys - no change
Clean out my keyboard - no change
Uninstall my keyboard driver and reboot - no change
Perform a system reset - no change

Anyone have additional ideas to solve this problem or what the issue may be?

If the same happens when using an external USB keyboard, it could be a software or setting issue. Then go back to factory conditions and try again.

If an external keyboard functions OK, try replacing the keyboard in the laptop.

I did a system reset. No change to the issue.
I haven't tried the external keyboard approach yet simply because I do not have one and am trying to avoid buying on just to test this theory. If I don't come up with any other suggestions, I will definitely try that before contacting Toshiba to repair the laptop (Thankfully it's still under warranty).

Most repair shops have externals.

Here these are a 10 buck item but the service counter is 150USD min charge. For me, it's cheaper to DIY repair (buy the keyboard for testing.)

I understand folk do not want to buy a Volt meter too but when you are getting into repair, basic gear is needed unless you want to take a chance.

In this case it's not a big loss either way. 10 buck keyboard for test or 15 dollars for a keyboard at

I see the keyboard removal at the 2:30 mark at so it looks like a 10 minute job once you get your new keyboard.

So there it is. About 15 to 25 dollar job.

ONE LAST THING. Is it in warranty?

PS. Forgot to write about the odds.

In reply to: Most repair shops have externals.

From my past experience I always test with the external first. If the external works then a new keyboard has fixed it up hundreds of times. The only two times it did not was when the laptop had been flooded with juice or soda. This is still worth trying yourself since the OOW (out of warranty) costs tend to run well over 100.
