Let us know how it goes; it's clearer now from below why you need this.

Ah yes. I guess you might have to try the freebsd-acpi list about that,
after reading the ACPI debugging section of the Handbook, providing your
dmesg and probably an acpidump of your ASL as shown there.
I don't know the current status of suspend/resume on amd64, nor anything
about your HP Probook 4510s. The freebsd-mobile list might be a better
place to start, at least to ask whether anyone else shares your problem?
