Thank Bykov Vladislav and Kevin Oberman's recommendations. Later I received an 
e-mail, 

immediately compile the kernel (make a note #options VESA).But the problem 
persists, dmesg 

Information Reference url http://url.cn/SQ0vXD. 

 

Even worse thing is, I do use "acpiconf -s 3"debugger, resulting in a notebook 
can not boot 

until yesterday afternoon for a good notebook motherboard, now do not dare to 
use “acpiconf 

-s 3” testing. 

 

Do you have suggestions for me? Thanks you~

Can you please try to install video driver for your card and remove VESA device 
from kernel configuration?

Hello,

       I am having a problem.

       My laptop is lenovo's zhaoyang K47A series HM65.

       I used ati graphics CARDS, Use the url (
<https://wiki.freebsd.org/Graphics> https://wiki.freebsd.org/Graphics) the
method of normal driving the graphics card.



      After set "

sysctl debug. Bootverbose = 1

sysctl debug. Acpi. Suspend_bounce = 1

sysctl debug. Acpi. Resume_beep = 1

acpiconf -s 3

"

The laptop can't resume, the screen no display, no beep sound.



Disabling ACPI not helps to fix the problem. All files downloaded from
http://url.cn/WVISGF.

Have you tried building the kernel without VESA? Many laptops won't resume if 
you leave VESA in the kernel build.
