ACPI problems on Lenovo 3000 N100

[Krasznai András]

Good afternoon!


I have been using FreeBSD since 5.3. Nowadays I am using FreeBSD-7.1-PRERELEASE on my Lenovo 3000 N100 laptop.

I tried to use the suspend function (I want itt o go to suspend when I close the display) and the laptop behaved strangely; closing the LCD-display it eventually switches off but never wakes up; the only thing I can do is to switch it off and on, and wait for fsck finishing...


The laptop is installed as a multiboot machine and the suspend function works correctly in Windows VISTA so the hardware is able to perform suspend.

After reading the FreeBSD handbook I tried various settings with acpiconf, but no success:

acpiconf -s S3 and acpiconf -s S4  caused various crashes on the machine,

and the computer did not accept acpiconf -s S5 : said that level 5 is unsupported ACPI mode.

Has anybody any success with this type of laptop regarding suspend functionality?

I get other messages from ACPI similar to the following, which - by the handbook - mean that the ACPI may be broken.

(ACPI-1287: *** Error: Method execution failed [\\_SB_.PCI0.LPC0.FIGD._STA] \\
     (Node 0xc3f6d160), AE_NOT_FOUND)



I attach some diagnostic information according to the Freebsd handbook; pls. I also attach my kernel configuration (GENERIC_K).

Give some advice how te get this machine perform suspend.

Best regards

Andras Krasznai
