My keyboard does not work with a code 10 error

Question

Original Title: My keyboard does not work.

I am using a Lenovo wireless silver silk 2.4 ghz wireless keyboard. The device was working fine until Thursday.

But now, in device manager, I am getting this

• This device cannot start. (Code 10)
• The device is not in a valid state to perform this request.

I have restarted my PC and have done all the updates that there were. I have troubleshooted it and updated it to the most recent driver.

I am using Windows 8.1 on a Lenovo A730.

Can anyone help me?

Only the volume buttons work and the space bar is able to unlock my computer. Also, the Fn keys work when i press the Fn button, so its not a battery problem.

Hi Eva,

I appreciate the effort that you have put to try and fix the issue till now.

Apart from corrupt, outdated or incompatible driver for the device, this issue might occur if the device configuration for the keyboard fails to load. There are certain registry entries for each device as resetting them might fix the issue.

Before following the method:

Note: This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, you can refer to the following steps to back the registry files on the computer:

• Press Windows and R keys to open the run box.
• Type ‘regedit’ and press Enter from the keyboard.
• Open the file option on the menu bar.
• Click on Export and save the file with a name on the desktop.

If you want to restore the file, you can do so by double clicking the file that you have saved on the desktop.

Hi typing on the onscreen keyboard. you have my sympathy.

last Fri some intermittent silver silk keys sticking, by midnight keyboard would let me log in & then only the volume keys worked. 2 hours with 'sarah' from the sub-continent. exhausted after the 5th or 6th time of her asking "sir, do you have F2, F3, F4 all held down ? now i want you to remove the batteries - put them back in & closing not taking your finger off. is there red light is blinking ! (meanwhile i have a finger cramp)

It's not pretty, 3rd Silver Silk- same exact keyboard problems, sign in then nothing.  "sir, may zi take your case number ?"  didn't i just do & to be sure your address, (i'd given it yesterday, wasn't with or associsted with my case #, zip code - at one point after i gave her my cell number she paused & said "& that number you just gave me is 708.556.9233?

i warned her thst would sell family to the taliban

i waiting for UPS
