I've placed copies of the dmesg.boot from each of RELENG_6, RELENG_7, and HEAD in www.catwhisker.org:~david/public_html/FreeBSD, as well as copies of the kernel configs (joining the ASL/DSDT stuff). I just added output from "sysctl hw.acpi" from each, as well: bunrab(4.11-S)[3] ls -l laptop.i8200.* -rw-r--r-- 1 david staff 91343 Jun 29 17:22 laptop.i8200.asl -rw-r--r-- 1 david staff 28033 Jun 30 06:51 laptop.i8200.dmesg.boot.6 -rw-r--r-- 1 david staff 30401 Jun 30 06:54 laptop.i8200.dmesg.boot.7 -rw-r--r-- 1 david staff 34133 Jun 30 07:41 laptop.i8200.dmesg.boot.8 -rw-r--r-- 1 david staff 12622 Jun 29 17:22 laptop.i8200.dsdt -rw-r--r-- 1 david staff 975 Jun 30 08:55 laptop.i8200.hw.acpi.6 -rw-r--r-- 1 david staff 974 Jun 30 08:57 laptop.i8200.hw.acpi.7 -rw-r--r-- 1 david staff 976 Jun 30 09:08 laptop.i8200.hw.acpi.8 -rw-r--r-- 1 david staff 9502 May 7 15:05 laptop.i8200.kernel.6 -rw-r--r-- 1 david staff 9154 Jun 8 2007 laptop.i8200.kernel.7 -rw-r--r-- 1 david staff 9399 Jan 12 17:26 laptop.i8200.kernel.8 bunrab(4.11-S)[4]=20 >... > Had a quick look at your .asl, doesn't mean much to me, but I wonder >=20 > . are you running the latest BIOS/ACPI upgrade available from Dell? > "Project: DELL Mojave", > "Date: 01/28/1998", > "Ver: 1.00.04" Errr... hmmm?

My settings under "Power Management" (in the BIOS config/setup menus): BATTERY AC _______ __ Brightness: [XXXXX ] [XXXXXXX ] Power Management: Enabled Enabled Display Time-Out: 4 Minutes Disabled Disk Time-Out: 3 Minutes Disabled Suspend Time-Out: Disabled Disabled 22D Time-Out: Disabled Disabled Smart CPU Mode: Enabled Enabled Display Close: Active Active=20 Ring/Event Resume: Enabled Alarm Resume: Enabled Wakeup On LAN: Disabled Intel SpeedStep(tm): Enabled CPU on AC: Automatic CPU on Battery: Automatic Auto On Mode: Disabled Auto On Time: 00:00 Most of the above are defaults; I disabled Suspend & S2D on battery, as well as told it to remain active on battery if I shut the lid. Everything else should be a default setting. > . not running it in a dock are you?

I did remove the keyboard, and it appears that the keyboard acts as a secondary heat sink for the video card; I did clean both surfaces (the chip & the underside of the keyboard) and place a thin layer of thermal compound on the chip before re-seating the keyboard. That does not appear to have had a noticable effect either way. Thanks for the help so far. I'm getting the distinct impression that it's likely that some of the hardware is failing, and that I either need to have the machine repaired by someone competent to do so (as opposed to me) or I need to consider replacing it. (There are, after all, significant parts of the machine that are over 5 years old. And I've been tracking various FreeBSD branches on it just about daily as long as I've had it and it's been working.) Peace, david --=20 David H.
