Hewlett-Packard HP Compaq Pro 6300 SFF: Graphics Card Not Being Detected

@1L1mited,

The reason why you got this loss-of-battery-power message is because you followed the CMOS reset procedure.  There is likely nothing wrong with the onboard battery.

Just enter the correct time and see where it gets you.

Thanks for your reply. How do I do that? I can't get access to anything because nothing is happening when I press F1 on my keyboard. I tried using a different one and it didn't work.

I only get the black screen with battery message. It does not boot to Windows...unless I need to leave the computer on with the black screen longer than 2 minutes. Not sure what to do next.

@1L1mited,

Is your monitor connected to your graphics card, or are you connected to your desktop's DisplayPort?

If your graphics card is still fitted in your desktop, power down, unplug from power, hold the power key for 4 seconds, and remove it.  Connect your monitor to the DP video port and start 'r up again.

You should be able to boot up -trust me, I have done this a few times. Give it about 5 minutes if necessary.

Kind Regards,

Same issue; trying the CMOS battery reset and we'll go from there.

Still getting this screen after removing the graphics card, even tried removing the battery and resetting the CMOS again. Any other steps to take?

@1L1mited,

For Zeus' sake, this is an issue I haven't experienced yet with my HP Pro 6300 SFF.  So, if you happen to have a new CR2032 3V Lithium coin cell battery available, it may well be worth-it to try that.  (Some Dollar Stores sell them, or any grocery store likely sells them too.) 

Kind Regards,

@1L1mited,

Other approaches worth a try: rather than hitting the F1 key -which you said doesn't work, have you tried hitting the Enter key and/or the Esc key, and/or Ctrl-Alt-Del?

Alrighty, I will get new batteries soon.

Nothing seems to work with that either.
