F1 on startup

[dbelfield]

I removed the back from my HP 27 K300a AIO to clean the dust out. I didn't touch or replace any hardware. After the back was put back on the Bios screen appears asking to press F1 every time on startup. I noticed it loses time and I have replaced the battery to see if this was the issue, however, the F1 prompt still appears.

@dbelfield Welcome to HP Community!

I understand that you are having to press F1 every time that you start the system to continue to boot.

Generally, this should happen only once when you make a hardware change or clear the CMOS. If it is continuous, this indicates that something may not have been connected or re-seated properly when you change the case. Could it be possible that the RAM or the RTC battery may not be fully engaged? Have you taken a look at all connections to ensure that everything is fully seated/attached? Is the date and time in the PC correct?

You might try to restore your BIOS default settings to see if this might resolve the issue. Also, do you have any bangs in the Device Manager?

To perform the BIOS recovery, follow the below steps:

Press the Windows key and then followed by the key "B" this time and then the power button for around 3-4 seconds, then release the power button and continue to hold windows+B for 3-4 seconds more.

If you really would like to disable your post messages, you can go into your BIOS, under the Advanced tab, select Power-On Options and disable your Post Messages and disable your Bypass F1 Prompt on Configuration Changes.

I hope this helps.

Thanks for that. 

I have tried to reset the bios but no change and disabling the post messages doesn't work either. 

The system time is lost at shut down. I have replaced the battery and checked its in properly. Ram is secure.

Still no change.

Cheers
