Have you tried disabling the fn key in bios?
</div>


<div>
Thanks. &nbsp;I just checked the BIOS settings and there is nothing for Fn key. &nbsp;This is an American Megatrends 2010 BIOS.

Try to change your keyboard layout from control panel &gt;&nbsp;Region and language &gt;&nbsp;keyboards and languages &gt;&nbsp;change Keyboards &gt;&nbsp;check if English (United States) is selected.

Try an external keyboard to see if the issue persists there. Also, you can try a bootable DVD to see if the keyboard works from some different OS environment.

Thanks. &nbsp;Did the external keyboard and all keys work on external fine.

I didn't see any Windows 10 supported driver for your laptop in Toshiba Support website, &nbsp;and this means that your computer drivers are not set exactly for Windows 10. you had to check this before upgrading to Windows 10.<br />

Its possible to be a Win 10 driver issue, &nbsp;but it could also be a coincidental hardware failure. &nbsp;Try booting the laptop from an external source: &nbsp;old windows install disk, or a linux boot disk, or any bootable device that will accept keystrokes. &nbsp;If the laptop keyboard works there, then its very likely a win 10 driver issue. &nbsp;If the keyboard fails, then its a hardware issue. &nbsp;Could be as simple as the ribbon connector jarred loose or maybe you need a new keyboard (they are not expensive and usually easy to replace on windows laptops).

Are you talking about the upper numeral keys or about the numpad at the right?<br />
Have you checked if this tip works for you?<br />
<br />
Click on Start --&gt; Control Panel --&gt; Ease of Access --&gt; Ease of Access Center --&gt;<br />
<br />
Click on &quot;Make the mouse easier to use&quot; --&gt; Under Control the mouse with the<br />
<br />
keyboard, uncheck the check box &quot;Turn ON Mouse Keys&quot; --&gt; Click on OK.

<div>
When was the last time you clean the keyboard with some compressed air, something maybe sticking or you just might need a new keyboard
</div>


<div>
Natty &nbsp;Thanks. &nbsp;The problem key's work fine when I push in the Function Key. &nbsp;Don't think it's a sticking key problem. &nbsp;Since it's a questionable Windows installation (meaning missing drivers for other processes) I decided to redo the windows installation. &nbsp;That led to other problems during the install. &nbsp;such as: &nbsp;the windows 10 install freezes at the very early stages of the install process. &nbsp;This leads me to wonder about the condition of the hard drive.

<div>
Fred, &nbsp;Will do the diagnostics on this. &nbsp;It's become a low priority issue and will try to get to it later this week. &nbsp;Now I have a bigger issue to solve.<br />
<br />
See my next question<br />
<br />
Thanks, Dan

On a Toshiba Satellite L675, with Windows 10. &nbsp;I'm having trouble using the 1, 2, 3, 4 keys and the space bar. &nbsp;When I push and hold the FN key they work, Without pushing the Function key they do not work.<br />

This is a Windows 10 upgrade from Win 7. &nbsp;All worked well before the upgrade.<br />

I've uninstalled drivers and rebooted. &nbsp;I've downloaded and installed new drivers from the Toshiba site. &nbsp;None of that works. &nbsp;Any more suggestions to make these unusable keys work again.?

Toshiba Laptop Function Key

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.
