KeyBoard Fails in BIOS ,Dellgx270

Kaldeep types faster than I do.

And please don't double-post the same question.

Hi NoorTanwri,

You may try the following steps.

• Disconnect any external peripherals (flash drives, printers, external hard drives, keyboard, and mouse) including power cables from the computer.
• Press and hold the power button for 15 seconds.
• Reconnect only the monitor and keyboard and boot to BIOS screen to see if the keyboard works.

Also try reseating the coin cell battery to load BIOS defaults.

Keep me posted with the results. I will be glad to assist you further.

Try clearing BIOS:

1. Power off, unplug
2. Press/hold power button for ~15 sec
3. Open case and remove motherboard battery
4. Press/hold power button for ~30 sec
5. Reinstall battery (right-side-up!)
6. Close case and connect keyboard to one of rear USB ports

Ok , Cleared BIOS  , as you told me in 6 Steps , everythingz okay now , but i can use PS2 keyboard only in BIOS , and USB keyboard allow me to press just a single key , after that USB keyboard freezes , whenever i press any one key in BIOS , its my Habit to Switch Num on and off again and again in bios by waiting , and this time whenever i switch it off (if its on ) it freezes , i left to do so ,BIOS screen moved me to 'F1 to continue or F2 to setup ' now if i press f1 its fine , it goes to OS , but if i go to BIOS setting , it freezes , what should i do , should i change my USB keyboard , should i use PS2 , or Any SOLUTION for SOLVING the PROBLEM .

I want to use USB keyboard in BIOS as well as windows.

Waiting for reply from you

I have followed your steps , its fine now , but the only problem is , i can not use the USB keyboard in BIOS. just after pressing any one key of usb KB in BIOS it gets stuck . what should i do , Dell-Kuldeep M ,

Make sure USB Emulation is ON in BIOS setup, and try all the rear USB ports.

yes , USB Emulation is ON , and i have tried all USB rear ports , but just at a single re-start , should i check all by re-starting the pc .

STILL I AM FACING THE SAME PROBLEM , i am not solved yet  , i Cleared the BIOS , twice , in last 24hours , but still keyboard freezes in BIOS , USB and PS2 Both !!!

" i heated up each part of CPU "  and likely permanently damaged the motherboard.:emotion-3:

I Heated up ( I PLACED ALL PARTS IN SUNLIGHT FOR HOURS ) :( ,

Hi NoorTanwri,

As you have tried all the necessary steps, it seems that the issue is with the motherboard.

As suggested by RoHe and SpeedStep, it could be a result of the parts being exposed to heat.

However, before replacing the motherboard you may try downgrading the BIOS as an alternate to see if that works.

Note: Downgrading the BIOS may cause permanent failure of the motherboard. It is at your own discretion to try downgrading the BIOS.   

Please feel free to reply for any further assistance.
