HP keyboard KB 9970

why not buy a real keyboard. for USB?
vast types, even for $8.
hp what you never side what HP puter.??
hp made them for 33 years, 1984 to now.
endless.
my guess newer HP, like 10 years or newer
and has USB ports
then you found a USB to PS/2 adaptor (vast types exist)
but many dont work. right.
btw this is classic failure from 1999 to to now.
endless posts world wide,,,
the trouble is the PS2 keyboard, send commands very different that USB does.
Try this go to bios and turn on legacy USB>
maybe it can see he keyboad at boot (bios sees t first)
then BIOS passes this discovery to windows 10..
ive not touched or seen a PS2 keyboard, in years.
like year 2000?> 18 long years ago.
im old. worked them all.
PS/2 >>>>>adaptor >>>> USB modern system.
the adaptor must do 2 things, send power correctly to the KBD.
then translate PS/2 sings to USB sigs.
then BIOS needs to understand plug and play IDs from PS2
if missing IDs, or garbled, its born dead.

good luck there.
btw your pc is not PS2 certified so....

Things I see here.
1) The second Keyboard you plugged wasn't any good either.

2) The PS/2 port for your keyboard on your motherboard, isn't any good anymore.
Computer off, plug it into the Mouse PS/2 port, and use a USB mouse.
BIOS will reset the I/O address for that PS/2 port, and set it for the Keyboard, when the computer is turned back on.

You may have to;
A) Turn the computer off
B) Unplug from power.

C) Press the Power On button in, and hold it in for a count of 10 seconds. Let go of the Power On button. Do this same procedure two more times.

What you are doing is draining residual power, clearing CMOS Error Codes, and resetting BIOS back to the factory default settings.

Keyboard plugged in, USB mouse plugged in, plug the computer back into power. WAIT 1 minute, turn the computer on.

Still no?
Motherboard replacement.

You didn't unplug the old Keyboard, WITH the computer on, and plug the new Keyboard in, did you? It isn't a hot-swap device. The computer must be off when unplugging a mouse, or keyboard.

For additional questions please post in a Comment.

I believe that that keyboard is using a P/S2 connection, if so here is a video with a suggested solution you can try: https://www.youtube.com/watch?v=6OTjJ1yttgY
I hope this helps!

Printers drivers will sometimes lock the queue. uninstall the printer from the system and reinstall. if you cannot reinstall and get spool errors try this:

hold the windows key down and hit r on the keyboard.
in this window type in cmd and hit enter.
in the command prompt type

sc config spooler depend= RPCSS

if you can't uninstall read this article to manually remove a printer in windows

I presume it is a PS/2 keyboard one that plugs into the Green Connector at rear of PC, if so, then these ports often fault, with the mouse being OK. The best way around this is to get a cheap USB keyboard, and install it. Ensure you set the USB ON in BIOS too. You could try uninstall/reinstall of KB from device manager first.

if its a ps2 kb you prob just killed it by plugging it into a computer with power on. if usb than its ok to do that. if its not lighting up than its dead. get another kb

install the utility program of that new HP KB n Mouse

Uninstall the keyboard driver and let windows driver manage it,Should work fine.

i put my logiteck kb on sleep mode. Computer shut down next moring would not work for nothing Is there a power up sequence or somehting i need to do. Used to work, very strange.

Try External USB keyboard - If that works -
remove usb kb

Open the chassis and reseat the kb connector. Try again.

If that fixes it, you're set. If not replace the kb.
