The Evo N800 has some known issues with its DSDT (an ACPI table in the ROM). If it is possible to override the DSDT under FreeBSD, you might want to try the one on this website: http://acpi.sourceforge.net/dsdt/view.php?id=3D24 Now, I know this is a Linux website, but it might give you some clues as to the ACPI issues with that laptop: http://website.atix.de/dt/notebook/linux-compaq-evo-N800v.htm Keep in mind that the Linux ACPI stack is slightly ahead of FreeBSD's, so someone's success with that laptop under Linux (with a modified DSDT) may not translate to the same success under FreeBSD today. > -----Original Message----- > From: Georg-W.
