How to reset IPC 847 bios password

Hello,

How can i reset  IPC847 bios password?

I try to remove battery more then 1 hour but it's not working still have a password.

Hello valmet,

I'm not aware of any procedure, that would lead to that result. Maybe your BIOS-chip has to be replaced.

I guess Siemens Technical Support can help you. Try to create a support request at https://support.industry.siemens.com/tf/ww/en/header/supportrequest/.
