What does 'sysctl debug.acpi' say? There are some settings there re the EC, especially perhaps the default 750ms timeout, however I don't think you can update these settings until after boot (ie in /etc/sysctl.conf) > ACPI Error (psparse-0633): Method parse/execution failed [\\_SB_.BAT0._STA] > (Node 0xffffff000269d740), AE_NOT_EXIST > ACPI Error (uteval-0318): Method execution failed [\\_SB_.BAT0._STA] (Node > 0xffffff000269d740), AE_NOT_EXIST > ACPI Error: No handler for Region [ERAM] (0xffffff0002694180) > [EmbeddedControl] (20100331/evregion-487) > ACPI Error: Region EmbeddedControl(0x3) has no handler > (20100331/exfldio-383) [..] > ACPI Error (psparse-0633): Method parse/execution failed [\\_SB_.BAT0._BST] > (Node 0xffffff000269d6c0), AE_NOT_EXIST > ACPI Error: No handler for Region [ERAM] (0xffffff0002694180) > [EmbeddedControl] (20100331/evregion-487) > ACPI Error: Region EmbeddedControl(0x3) has no handler > (20100331/exfldio-383) These are trying to get the battery status from the battery, which is connected via the EC (as is common), but which is failing to respond.

Have you checked the HP site to see if there's a later BIOS and/or EC flash update available? If so, please try that before aything else. If not, can you boot 8.0 again (from dvd, disc1, the fixit disc, or the USB memstick.img) to be sure that it still works properly on 8.0, ie to be sure that your hardware hasn't failed around the same time? If it still works right on 8.0 but not on 8.1, try to get a full verbose dmesg from both OS versions, and submit a PR showing both of those and a link to a dump of your ACPI AML according to the Handbook section 11.6: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/acpi-debug.html cheers, Ian
