How to clear cmos HP Pavilion 500-023w Desktop PC

HP Recommended
HP Pavilion 500-023w Desktop
Microsoft Windows 10 (64-bit)

Front and rear USB are disabled in the BIOS and pulling the battery does not clear it. I also  tried changing the jumper I thought would do it but after leaving it over night the bios seemed to require input but the USB keyboard could not be used.  I need to know,  if you can help me, how to clear the bios to get the usb back on so i can use the keyboard at boot time please. Thank you in advance for any help.

Hi,

 

When did your issue start?

 

Why do you suspect that the USB ports are disabled in the BIOS?

 

Why do you think that input was required after removing the battery and also using the CMOS jumper?

 

Perhaps the keyboard is bad?

 

Try a wired unpowered USB2 keyboard in the back USB2 port.

Because I  disabled them.

 Because it  was a time needs to be set prompt

Hi,

 

 "Because it  was a time needs to be set prompt"

 

What does that mean?

lol When you boot up with say a  dead battery and it asks you to set  the time. Or tells you  it is not set.

For your information i disabled the front and rear usb in the bios. Was testing a couple add in cards. Well when i rebooted without turning the internals back on i have no access to a keyboard untill the add in USB cards load a driver, SOOO i can not  use the  bios I can not  fresh install windows. that sort of stuff. Hope that clears it up  for ya.

Hi,

 

Interesting response. lol

 

Read thru this thread.

 

 

 

 

BTW--I can pull the battery in my PC and I don't get a prompt to set time and date.  Not every BIOS will cause a prompt.

Thank you for  a pointer but I am not password locked, i simply need to  ENABLE front and/or rear usb. I cant seem to find an HP WMI Provider that works with my machine so i can use  the  BiosConfigUtility64.exe utility and write a corrected bios.

Unable to connect to HP WMI namespace: 'root\HP'/

Hi,

 

Perhaps booting a BIOS flash from CD might work.

Great idea. This machine never got a bios update as far as I can tell so if someone knows where to get this bios in a flash setup i would be grateful.
