good morning and very happy new year to all

 

please, i have a strange problem with my genius ps2 keyboard

 

every time i rebooted my pc or after some setting changes in the bios the keyboard is not working

 

when i unplug the keyboard and plug it gain everything is ok

 

the keyboard is just two years old and i think my problem might be either a corrupted bios or some windows corrupted files

 

no virus, no malware or any other suspicious software on my pc

 

many thanks in advance

 

happy new year to all

If you have a spare keyboard, try that first.  It does sound like the keyboard is not geting reset properly on power down, OR this may be one of those with a hot key on it to turn things on and the BIOS isn't resetting it properly.  If so, disable the hot key function and see what that results.

hi to all,

 

sorry for my return again but unfortunately i still have problem with my keyboard

 

the keyboard is still not working after bios settings !

 

i have all ready clean the keyboard with air pressure but nothing done

 

the strange thing is the keyboard is working absolutely fine after reboot but is not working after any bios settings (including bios defaults)

 

certainly i can buy a new and better keyboard than this (genius ps2 kbr) but i have to know what is going on...

 

thanks

Try a new CMOS battery. After replacing it reset your BIOS to default. Only replace the CMOS battery if your new keyboard also has the problem. If your new keyboard is working fine then you do not need to replace the CMOS battery.

good morning dear JohnC_21

 

i thank thank you for your reply

 

as far i remember my cmos battery is almost two years old so i think is still have life

 

i have all ready cleared my bios 

 

the strange thing about my keyboard is not working after bios setting changes !

 

i haven't noticed any errors while the pc is rebooted

 

the only think i have to check is to remove the battery from the motherboard for an hour and hoping for the best

 

thanks again

For the price of a CMOS battery if it's the standard CR2032 I would give it a try.

good afternoon dear JohnC_21

 

thanks for your kind reply

 

the price of a cmos battery is just euros 1.75 but i still do not think that my problem is the battery...

 

the pc clock is not yet loosing time

 

i will try to remove the cmos battery for an hour or longer and i will check again

 

the strange here is the keyboard is working absolutely fine and only when i enter bios and make some different settings the keyboard is not working

 

i will try to remove the cmos battery for an hour or longer and i will check again since i believe now that my problem have to do with bios 

 

thanks

If removing the CMOS battery does not work you may want to purchase a USB keyboard but you would need to determine if it's worth the extra cost vs unplugging and reattaching the PS2 keyboard.

 

If you go to the System Log in Event Viewer it may give a clue if it lists any errors related to the keyboard.

 

If you right click the keyboard in Device Manager, does it show any problem.  There may be a problem with the keyboard driver or some other system file not functioning. Have you tried using sfc /scannow at an elevated command prompt to correct any system file errors?

Glad it worked out for you. Thanks for the update. I am not sure but if you have a jumper on the motherboard that would clear the BIOS so you would not need to remove the battery for that length of time. I think holdiing down the power button with the CMOS battery and power cord removed would also cut down the time in case you ran into this keyboard problem again.

good evening dear JohnC_21

 

i thank you once again for your kind reply....

 

it seems that i still have problem 

 

i have tried another ps2 keyboard and is not working again after any bios setting changes !

 

yes, i have placed the jumper to the correct setting

 

i do not think that the motherboard's ps2 port have any problem since the keyboard is working

 

the only think i will try next is to update my bios to a newer version 

 

i think that my problem have to do with the bios, possibly a partial corrupted bios ?

 

i thank you for your kind help

Updating the BIOS may help. Just be aware that a bad BIOS flash can brick the computer. If you update the BIOS within windows disable any antivirus software and put the program on the root of C:\. Some motherboards like ASUS let you flash through the BIOS which is the safest way.

Try a cheap USB keyboard and see if that solves the problem.
