Logon impossible : no keyboard reaction

A friend has a laptop with Windows 8 (NOT 8.1), dutch language.
After problems with Windows he did a system restore which lasted more
than 90 minutes! After the restart it is impossible to logon :
no keyboard reaction! An external usb keyboard was then connected : same
result. So even the password cannot be entered.
However, the keyboard is reacting on using function keys to enter the
BIOS (UEFI). So I do not think that it's a hardware problem.
What could be the cause? And can this be repaired??
He doesn't have a repair disk or an installation DVD. Is it possible to
download such a disk?
Thank you for some help!!

I once experienced something like this when imaging some workstations to
dissimilar hardware. The solution was to wait a few minutes and the keyboard
driver was finally loaded. I am not saying this is your issue, but have you
restarted the machine and tried to be a little patient?

I drove myself nuts with that issue, reapplied the image a couple of times and
even did a repair install..... all because I was impatient. In the end, I went
and got a tall cold beer and came back 20 minutes later and it was working. Very
bizarre.




Not that bizarre, I've seen that quite a few times

No effect. We waited more than half an hour while we were using another
PC to find a solution.
A restart holding the Shift key doesn't work (probably because the Shift
key doesn't work...).

Does the keyboard work if you boot Windows into its safe mode?

Try step #5 if the boot process is slow enough to detect the Shift+F8
key combo. Don't wait until you see Windows is loading or a Windows
screen since then it is too late. At the POST screen, hold Shift and
start tapping F8 repeatedly.

Look at the laptop's POST screen. It might say to hit F2 to get into
its recovery mode (and before anything of the OS loads). Instructions
with the laptop probably tell how to create recovery CDs but your friend
probably didn't read the manual. Those are created from the recovery
partition on the hard disk in the laptop. So now you'll have to hope
the that recovery partition is still intact and usable (no corruption,
no repartitioning) if you are stuck having to restore the factory-time
image on the laptop.

How the laptop performs a recovery installation depends on brand and
model which was not divulged here.

There is System Restore (use a Restore Point), there is Refresh
and there is Reset. Each does different things...

All it takes, is interference with a USB driver, to kill HID input
on modern computers. Someone reports seeing a yellow triangle
next to a USB item, as a root cause. You would think an OEM restore,
would have exactly the right drivers for the hardware.

If the mouse was working, you could use virtual keyboard to
do the login. But you need to be able to click on this with
your mouse, and you can't get past the initial boot screen.

Even getting to Safe Mode is a pain.

You could use "Remote Desktop" to control a computer, but that
requires setup before hand too.

How long have you waited?

I'd walk away and give it a lot of time.


If that does not work

try hitting the Shift and then F8 upon booting and see if you can get
the "recovery" option

I would try switching USB ports for the external keyboard, you have nothing to
lose.



Did that, same result...

Shift - F8 : doesn't do anything.

To extract the OEM license key (since those machines
don't come with a COA sticker...)

"Extract license key from win8 OEM machine.

1- Download and create a Linux Live CD,
Linux Mint or Ubuntu for example
2- launch it
3- open the console called Terminal
4- type: ls /sys/firmware/acpi/tables

It will shows you if you have a MSDM table
The MSDM table holds the Windows 8/8.1 OEM license key

5- then type: sudo hd /sys/firmware/acpi/tables/MSDM

The license will shows up on the right of the output.
25 characters (and the characters are from a restricted
set of characters, so not all alphanumerics would be valid).

You can Torrent an MSDN subscription DVD.

Or, you can use this, but only for certain kinds of license
keys. The OEM license key might not work. Neither would
an Enterprise license key. You cannot download Starter
edition this way, either.

"mediacreationtool.exe"
http://www.askvg.com/official-tool-t...llation-media/

If you had the media, the presence of an MSDM table
automatically activates the OS. If the laptop did not
have an OEM key stored in the BIOS for some reason
(a Windows 7 to Windows 8 upgrade perhaps), there
are install-only keys that will get you past
the stage of the re-installation, where it
prompts for a license key, and it will not
accept clicking "Next" to get past it.

Windows 8.1 Pro: XHQ8N-C3MCJ-RQXB6-WCHYG-C9WKB
Windows 8.1 Co 334NH-RXG76-64THK-C7CKG-D3VPT

Windows 8.0 Pro: XKY4K-2NRWR-8F6P2-448RF-CRYQH
Windows 8.0: Co FB4WR-32NVD-4RW79-XQFWH-CYQG3

I don't expect those will work in mediacreationtool.exe,
but you can try them :-) Since mediacreationtool (or any
other Microsoft-provided download method) is tricky about
whether you're getting the 32 bit or 64 bit version,
be careful that you're getting the correct download.
Otherwise, you'll have wasted several hours of download
time for nothing.

When you use mediacreationtool.exe, you should be
getting a single-image install.esd type DVD. Regular
installation media has install.wim which can be opened
for random access with 7ZIP. The install.esd DVDs
cannot be opened with 7ZIP. The install.esd is encrypted.
A *unique* install.esd is created for each person doing
a download. So these are not exactly the same as an
MSDN subscription DVD (which has install.wim and
is a lot more flexible for PC repair people).
But if it works for the reinstallation, most
people don't care about such details.

HTH,

Try shift+f8 or just f8 before windows start loading. You can also try
ctrl+alt+del at login screen. I had that problem for a long time. Then one
day something happened and the problem was solved. I think my problem was an
update. You could uninstall last updates after that problem showed up.

I didn't see you mention anything about the mouse, is that working?

Yes, the mouse works fine... on usb-2 and usb-3

Try shift+f8 or just f8 before windows start loading. You can also try

No reaction...

ctrl+alt+del at login screen.

No reaction : once in the login screen all input on keyboard (internal
or external) doesn't work...

"Extract license key from win8 OEM machine.

1- Download and create a Linux Live CD,

2- launch it

I have several Linux Live CD's/DVD's but the machine does'n boot from
these. I thing "SaveBoot" (or something like that) is enabled in the
UEFI/BIOS but I cannot enter that UEFI/BIOS!!!

The laptop has Windows 8 (not 8.1) ; can 8.1 be installed with the same
key??
