Keyboard is not working

Hi everyone,
I was hoping someone could help me with a question,
My laptop keyboard is not working, it was working until I plugged in a usb connected wireless keyboard that I was working on a projector with, after I removed the usb connection it would not work not just the keyboard but also the mute button and the wireless button as well. I have already tried restarting the computer, checking device manger to see if the usb keyboard was somehow still connected, it was not. No, nothing was spilled on the laptop at all, I have a three feet zone of no liquids or food around my laptop at all times. It is less than a month old, a Zbook 15.
Any sort of help would be great thanks.

All of a sudden my keyboard and trackpad don't work on my Macbook. USB keyboards and mice work fine. I took off the keyboard and tried it on another Macbook and it worked fine. Don't know if any recent updates or firmware changes have been done. Any ideas of how to fix or is this a motherboard issue?

Apple USB keyboard does not work with one internal usb port

Hi everyone,
hope someone can help me to solve my problem. I have a MPB13 retina late 2013 since something like 3 months. I have additional screen (dell), usb wired keyboard (apple) and BT magic mouse.
Since a few days, my usb keyboard does not work well. It only want to work properly when plugged to the rights side usb port internal port and not anymore on the left one. It also work on a usb external concentrator. Before, I had no problem, it worked perfectly. There was no problem such as cofee on it...
After searching the web on such problem, I tries a few things such as:
I tried the keyboard on another computer (windows): works fine
I tried usb stick and external DVD reading on the left internal usb ports: works fine
I switch the MPB off and turn it back on: the usb keyboard still does not work on the left usb port
I tried the SMC and PRAM reset : nothing
Any idea ??
Thanks
Guillaume

Hi and welcome the forum!
Try uninstalling all USB hub devices from the device manager and reinstalling them again, particularly the keyboard's.

Hp Mini 110 1013tu Keyboard is Not working after upgrade to win 7

Hello need help on weird happenings to my keyboard..
Before i upgrade the Operating System From Windows XP to Windows 7 the Hp Mini 110 is working fine..
All keys on keyboard is working and touchpad is also working.
But after upgrading to windows 7 some keys on keyboard are not working like z,x,c,v, left ctrl and other more keys..
what do you think is the problem??
Hardware Issue? or Driver Issue?
please help thank you..

Hello @MysticDragon ,
Welcome to the HP Forums!
I understand some of the keys on your keyboard are not working after installing Windows 7.
I do not see any drivers available for your notebook for Windows 7 on the HP website, so their might be some compatibility issues as it's going to rely on Windows update to find current drivers. This doesn't mean it will not work, but I cannot say for sure that it will.
Try this:
1. Click Start.
2. Click Control Panel.
3. Click Clock, Language, and Region.
4. Click Region and Language.
5. Click the Keyboards and Languages tab.
6. Click Change keyboards...
7. On the General tab, make sure English (United States) - US is selected in the Default input language field.
8. Click on any other keyboards in the Installed services list.
9. Click Remove.
10. Repeat for all other non-English (United States) keyboards.
You may also want to try rolling back to Windows XP and see if the issue persists. It is possible the issue is coincidental and not the direct result of the update to Windows 7.
Let me know if this works!

You might have activated a Windows accessibility feature that requires to hold down a key for a longer time to make it work.

Some have reported that pressing F9 and the Windows key simultaneously one or more times has worked to fix issues with the keyboard not working.

Keyboard does not work after using Support Drivers

I have a Macbook Pro 4,1 15" 2.4GHz C2D, and managed to get Bootcamp installed on it with Win7 Home Pro. I have verified that it runs correctly, but it is missing many of the drivers needed to make things run smoothly. I no longer have my Leopard disks that the machine came, so I figured the WindowsSupportDrivers would be the way to go.
When I install them and reboot, the keyboard does not work. When I hit capslock, I get the caution notice indicating underneath my password field indicating the capslock key is on, so it's not like my entire keyboard is disabled. The system is unusable right now, since I have to enter my password to login, and it does not take any keyboard input. Using an external keyboard did not resolve this issue.
I did a system restore to get it back to a usable state for the time being.
Is there an alternative to the BCA support drivers or the Leopard disk? What's going on with my keyboard after the driver update?

Maybe you have installed obsolete drivers. If you have Lion, open Boot Camp Assistant (Applications > Utilities) in OS X and download Boot Camp drivers

After Recovery with CD Satellite C660-1FE keyboard does NOT work

Hello,
A month ago I purchased a Toshiba C660-1FE. After three weeks my HD broke down. I bought a new HD from Western Digital and replaced the broken HD. As I did not make an recovery image of my HD, I had to order the Product recovery discs off the Toshiba website (3 discs, of which disc 1 and 3 were the only one's required for installation).
Now, I have the problem that my laptop keyboard does not work. I am currently using a USB keyboard and mouse to replace my keyboard and touchpad of the laptop.
The laptop keyboard works fine in BIOS. Therefore, I hope it's just a driver problem.
I have:
tried finding and installing lots of drivers on from the toshiba website, no result.
tried changing settings in the bios (usb enable/disable).
tried to fix the problem by re-installing the entire computer again several times.
The keyboard seems to work until windows loads. When the system is starting up I can press caps lock and num lock and the green lights come on. This all stops working once the windows startup symbol appears.
Perhaps a second problem in the device manager: under the display-adapter, 2 subcategories have exclamation marks: it says Mobile Intel(R) 4 series express chipset family twice! I can't seems to fix these with any drivers I can find either. When I check the settings I have this message (google translate since it was in dutch):
+The digital signature for the drivers for this device is required, can not be verified. Possible after a recent hardware or software change a file that is installed incorrectly signed or damaged, or is malicious software installed from an unknown source. (Code 52)+
+You need to restart the computer to this device changes to take effect.+ (obviously I tried that too)
Can someone please give me some help? I am at the end of my wits.
Sincerely,
Daniel

Hi MisterX,
thank you for your response. I have tried these things and there is no such thing as PS2/keyboard in device manager. It's as if the Hardware is not even recognizable in windows. I am starting to doubt whether I got the right Backup CD.
I wrote the following e-mail to [email protected]:
+Dear Toshiba,+
+after receiving the recovery CD's for my toshiba c660-1FE, it turns out that the drivers for the keyboard and touchpad are not installed. I have tried many things to get around this but it seems to me that I have received the wrong product recovery CD's. The chipset drivers are not the right ones, the overall layout of this version of windows 7 is different from before and when looking for answers in the toshiba forum I have concluded that the recovery CD's could be the wrong ones.+
+My laptop: Satellite C660-1FE+
+serial: 5B378048K+
+Part-nr: PSC0LE 02M0TU26DU+
+Recovery CD's I received are CD's 1-3 with serial R14254DU+
+Would you be so kind to check whether these CD's should be 100% compatible with my laptop?+
+This would be greatly appreciated,+
+Daniel+
MisterX, do you know any other emails I can forward this too? Or anyone who could perhaps tell me if I got the right CD's? They are taking their time to respong to this...
Kind regards,
Daniel

My mac's keyboard is not working with my mac.the green light blinks and i cannot get onto my mac. everything on the support questions does not help because i cant go on the mac and i cant sign in

my mac's keyboard is not working with my mac.the green light blinks and i cannot get onto my mac. everything on the support questions does not help because i cant go on the mac and i cant sign in

If you can't sign in, then you can't troubleshoot and/or pair the keyboard until after that........ so, for that, you will need to borrow someone's USB wired keyboard in order to get signed in and to the Keyboard Bluetooth Preferences.

HT3917 My apple wireless keyboard is not working after new batteries installed

My apple wireless keyboard is not working after new batteries installed.

Do you get a steady green light to say there is a connection. If not, are the batteries the right way round. Do you have a monitor to tell the batteries strength. Is there a reading. Are the batteries good quality ones, Duracell, Energiser or Apple rechargeables.

A row from cap to return on Keyboard is not working.

It is for 17' Apple PowerBook G4 1GHZ. I bought it used off craigslist for cheap. The only wrong with it is one row on keyboard is not working from caps lock to return. Other than that, everything is working. Why? Is there a way to get a row on keyboard to work before I go ahead to order a used keyboard replacement off ebay? Let me know and thank you!

About the only thing to try, really, in this case is to reseat the keyboard ribbon connectors, which may clear things up. Otherwise, a new keyboard is probably the answer, though less pricey at this link, or just Google search "922-5776 keyboard" for more options.
Not an easy process, unfortunately, as one finds in the iFixit manual pages for that machine's keyboard, but reseating the connector is definitely the thing to try first.
Not to gloat, but it is trivial on a Titanium model.

Windows 8.1 freeze on any hardware scan or changes. USB wireless keyboard mouse not working

Problem : System Freezes frequently on any hardware scan or changes.
Symptom : Wireless Keyboard Mouse not working.
Caused by : VMkbd.sys located in C:\Windows\System32\drivers.
Issue : VMware player or VMware Workstation installed on Windows 8.1 causes compatibility issue leading to system freeze
Soultion : Please follow steps below
Step 1: Start > run > regedit
Step 2: Locate to this registry HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e96b-e325-11ce-BFC1-08002BE10318}
Step 3: On the left side plane, Right click on the registry {4d36e96b-e325-11ce-BFC1-08002BE10318} and then export it as backup. Just to be safe.
Step 4: Edit the UpperFilters, The value current would be kdbclass vmkbd. Remove the vmkbd. So only value left would be kbdclass.
Step 5: Restart your system and connect your USB wireless reciever. If all is well it will not freeze your windows now.
This worked for me. Hope this works for you. Enjoy..!!
