DL380 Gen7 Bios Password: Difference where to type numbers

Hi,

I found something funny / stupid.

We have 9 HP DL380 Gen 7  servers in one application. All have the same BIOS Password Containing letters and numbers.

However, on some machines we have to type the number on the numeric keyboard (on the right side under the NumLock key)  on the other we have to type the numbers on the top part of the aflanumeric keyboard. All machines have the same keyboard installed.

Any taught about this. Can this be solved?

Thanks for the advice.
