I'll ask on that Subscription issue. I have asked someone more skilled than I to review this thread.

One thing you have not looked at is the keyboard itself. Has the lappy been dropped bumped real hard prior to this happening? Maybe the connection came loose?

Fairly easy to check:

Gently lift it up and make sure the ribbon cable is seated.

Hello Murf ,

Thanks for reviewing this problem.. laptop has not been dropped/knocked in any way..
I take very good care of my computers, internally as well on the outside , keeping vents and keyboard clean & dust free.

I have seen suggestions of replacing/checking keyboard , but .. I wonder if that would make any difference to the Driver issue..

My reasoning could be wrong.. but how could a keyboard with cables in place etc work if there was a faulty driver issue...?
To my understanding everything needs the correct driver to make it function..

The original problem was solved by uninstalling the driver , and everything works perfectly with a USB keyboard.. the real hassle started, when as hoped , Windows failed to reinstall the driver on reboot and all attempts to reinstall the PS/2 driver has failed.

As well as having this dialogue here.. I keep looking for solutions , today I have come across few very similar discussions..

https://superuser.com/questions/7445...topped-to-work

http://www.tomshardware.com/answers/...g-windows.html

@ Tomshardware please look at the last post by Mustak..

https://answers.microsoft.com/en-us/...9-94d4e3985947

Suggested solution : To switch back to using a PS/2 keyboard, the user needs to edit the Registry to restart thei8042prt service. To do this, InHKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Serv ices\i8042prt,, edit the Startvalue and set it to a hex or decimal value of 1. Reboot and change to a PS/2 keyboard via the Keyboards section in Control Panel.

For the record , I did look at the registry and the Start value is set @ 3.. I did not change anything , just wanted to know where it was.

I'd appreciate your and Jintan's comments on this..

Have you tried a Hardware scan to see if it detects a problem.

https://pcsupport.lenovo.com/us/en/p...30/diagnostics

Under customization you can select Keyboard.

Also may seem silly but try this:

First, shut down the computer. Second, unplug the power cable and remove the battery for a moment.Third, press and hold the power button for about 60 seconds. After that, put the battery back in and plug the power cable again. Restart your computer and see if the keyboard is working.

Also you said you tried to install the ThinkPad UltraNav Driver for Windows 8.1 (64-bit), 8 (64-bit)

Thanks Murf,

First Lenovo link "product not available " but at any rate I've done the Lenovo scan ( several attempts) few weeks ago , it had " technical" issues and couldn't be completed.

Second suggestion , unless keyboard has the correct driver it wont work , and if you read the stuff we have tried when Jintan was helping, despite our best efforts , all attempts to install a new driver , has failed.

In my previous post , the last link from MS forum dealing with similar problem stated , quote >

" PS/2 keyboard devices are governed by a kernel-level service called i8042prt, short for the technical name for the PS/2 keyboard port. When a USB keyboard is added as a replacement for a PS/2 keyboard, the i8042prt service is forcibly disabled. This is to prevent a conflict between PS/2 and USB devices, but if a PS/2 keyboard is reinstalled, the service is not automatically restarted.

To switch back to using a PS/2 keyboard, the user needs to edit the Registry to restart thei8042prt service. To do this, InHKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Serv ices\i8042prt,, edit the Startvalue and set it to a hex or decimal value of 1. Reboot and change to a PS/2 keyboard via the Keyboards section in Control Panel."

According to the above, even if I installed a brand new keyboard it still not wouldn't work .. until things are corrected in the registry.

Since this has been going on for so long and I am in the process of setting up a new Lenovo Ideapad laptop , after the relative sanity of Win 8.1 .. Win 10 making me dizzy and have a lot of adjustments to make.. I will put this issue on the back burner for a bit.

Still , I would like a comment regarding the MS forum advice from Murf , Jintan or anyone else who might have been following this saga .

Many thanks for the support !

Try editing the registry for that one value. Can't make it any worse, just don't change anything but that one value.

Curious if you ever found a solution to the issue.
