Thank you quickly solve this problem. 
Last night successfully compiled kernel, but the problem is still not resolved 
after recovery sleep, the phenomenon persists, restore the notebook when there 
is energized action, but the hard drive lights under no response, the screen 
does not display, only the shutdown restart.

Run the patch through 'dos2unix' (/usr/ports/textproc/unix2dos package):
[root@ajenkins-hplaptop /usr/src]# file atrtc.c.patch 
atrtc.c.patch: unified diff output, ASCII text, with CRLF line terminators
[root@ajenkins-hplaptop /usr/src]# dos2unix atrtc.c.patch 
[root@ajenkins-hplaptop /usr/src]# file atrtc.c.patch 
atrtc.c.patch: unified diff output, ASCII text
(I had to fake a DOS-ified patch file for this example by running it through 
unix2dos first), but Hotmail likely converted it to DOS line endings.

1. Install FreeBSD source tree.
2. Download patch file.
3. 'cd' to /usr/src.
4. Execute 'patch -p0 < path/to/atrtc.c.patch'
5. Rebuild and install kernel ('make kernel 
6. Test suspend/resume.

Thanks so quick reply, for the use of patch files I have no experience, from 
the freebsd manual and the Internet did not find a reliable upgrade process, 
you can tell me how to use this patch file to upgrade atrtc.c it? For the use 
of the code, I was a rookie, needs your help. 

Or tell me which part of the contents of the manual freebsd can guide me to 
upgrade atrtc.c code, thank you.

No problem... attached.  And amd64 doesn't matter - works for x86-based 
computers with the basic CMOS RTC chip (PNP0B00).  Hopefully your 
suspend/resume problems are due to your ACPI BIOS needing to read/write info 
from/to CMOS and not finding a CMOS handler.

immediately compile the kernel (make a note #options VESA).But the

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?
You could dig up my kernel patch (Google "FreeBSD ACPI CMOS region support 
atrtc.c.patch") to play with, it works to enable suspend/resume on some laptops 
and should be safe to try.  I still need to clean it up (style, other 
suggestions) for submission to FreeBSD, haven't gotten around to it yet.

Thanks you~

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

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