Black screen before login, ”Time and date not set, F1: boot”.

[Fredrik5]

Hello,

I know black screen is a highly asked question here, however non of the answers I’ve seen here has been successful in solving my problem.

I have an HP Pavilion Desktop running Windows 10. When I try to boot it I first get a black screen with some system information and it days ”Date & Time not set. F1: boot”. When I press F1 it leeds to the windows logo for and a circle for a minute then proceedes to a black screen with a cursor.

I’ve changed the CMOS battery, without any difference. I can’t reach Task Manager, and still get black screen when I try to boot it in safe mode.

Does anyone have any idea on fixes/causes? The CPU is just half a year old, the harddrive is a year old SSD. The rest of the computer is from 2015.

Thanks in advance,

Fredrik

The message ”Date & Time not set. F1: boot” usually originates when the CMOS battery has died and needs to be replaced.  Since you have already replaced the battery did you then set the BIOS to defaults and save? That needs to be done also.

Since pressing F1 does not actually help in this situation, try to run the Diagnostics routine.

To run the Diagnostics routine, Start tapping the Esc key BEFORE starting the PC and then press the start button.
Keep tapping the Esc key until a popup menu shows. Then pick Diagnostics from that popup menu, F2.
Report back with the results.

Also you can set the BIOS to defaults by picking F10 and then saving , then exit.
