Sure enough, the Ctrl key on an external USB keyboard worked. Since the driver re-install didn't fix the Ctrl key on internal keyboard <b>AND </b> the Ctrl key on the external keyboard did work, I'm thinking it's a hardware issue. Agreed? (The fact, however, that both Ctrl keys quit at the same time makes me a little skeptical that it's the hardware.) Your thoughts?<br />

I have a Toshiba Satellite C855 where both Ctrl keys simply quit. Here's what I've tried so far. <br />
<br />

<div class="bullet">
I tried pressing Ctrl + Alt + Fn (Numerous websites suggested this for a Toshiba machine.)

I tried re-installing the keyboard drivers (by uninstalling the driver in the Device Manager and rebooting).

I tried rebooting in Safe Mode to determine if a particular app was causing the problem.

None of these steps fixed the issue.

Windows 8 is a personal computer operating system developed by Microsoft as part of the Windows NT family of operating systems, with an emphasis on improving its user experience on tablets. In particular, these changes included a touch-optimized Windows shell based on Microsoft's "Metro" design language, the Start screen, a new platform for developing apps with an emphasis on touchscreen input, integration with online services, support for USB 3.0, Advanced Format hard drives, near field communications, and cloud computing. Additional security features were introduced, such as built-in antivirus software, integration with Microsoft SmartScreen phishing filtering service and support for UEFI Secure Boot on supported devices with UEFI firmware.

A laptop or notebook is a portable personal computer with a clamshell form factor, suitable for mobile use. Although originally there was a distinction between laptops and notebooks, the former being bigger and heavier than the latter, there is often no longer any difference. Laptops are commonly used in a variety of settings, such as at work, in education, and for personal multimedia. A laptop combines the components, inputs, outputs and capabilities of a desktop computer, including the display screen, speakers, a keyboard, and pointing devices (such as a touchpad or trackpad) into a single unit. The device can be powered either from a rechargeable battery or by mains electricity from an AC adapter.
