F1 message when the laptop starts

What is the way to remove the “Press F1 to continue” message when the laptop starts. I got its processor replaced. Since then I am getting this message. The machine is Dell 1525.

I usually find more detail than F1 to continue.

Usually this points to an incorrect bios setting or a low, dead BIOS battery.

The Dell 1525 service and documents are at

Page 12 of shows the BIOS battery is the usual under one dollar part. If this was mine I'd measure that voltage and it under 3.0V it would be replaced. Then I would enter the BIOS to set date and time then save and exit (the manuals tell this.)

Hi thanks for the quick reply...

I think it cannot be the BIOS battery. If it was so, my laptop time and date would often mess up, but that never happens. Is that right?

If it is because of the hardware change that I made, for example, due to the processor that I got replaced and upgraded, how, then, I can get to the root of the problem and successfully fix it?

I don't want to upset you

But a new technician might write that. I ran repair shops and so I share what I do with you.

Your new screen error message is troubling. I did see such when someone tried to replace the CPU with an unsupported model. The fix was to put in the original CPU.

Did you try loading the BIOS defaults and saving? I can't tell what you know or did yet. seems to vet my answer.

screen error message...

by the way, this is exact error message that I get...

*** Processor SSDT data not found ***
Operating system power management for multi core processors will be disabled.

Strike the F1 key to continue, F2 to run the setup utility
