The pwrtest.efi is an UEFI Shell tool that help developer to confirm RTC wake function from a system(Support on both Intel and AMD platform).
最近在幫忙ODM看一個RTC Wake 問題，所以就順便寫了一個TOOL來驗證一些東西。原本遇到的問題也解決了，所以就順便把這個小TOOL分享一下給有需要的人使用。
Usage:
pwrtest -s3 -t 10 -w 60 ; 系統會在10 sec delay 後進入S3，然後在60 sec 後喚醒(Wake up)
pwrtest [-h|-s3|-s4|-s5|-s|-ss|-sx|-cb|-r]
-h help
-s3|-s4|-s5 ;選擇系統的Sx State (Intel platform)
-cb ;做coldboot ，我是透過 gRT->ResetSystem() 方式去做的
-ss ; 做Shutdown，我是透過 gRT->ResetSystem() 方式去做的
-sx value ; 支援AMD platform去做Sx State，因為填的SLP_TYP值不同.
value = 3/4/5 for AMD platform(S3/S4/S5)
value = 5/6/7 for Intel Platform (S3/S4/S5)
e.g,
pwrtest -sx 4 -t 5 -w 30 ; For AMD Platform, Put system to S4 after 5 sec, then wake after 30 sec.
pwrtest -sx 6 -t 5 -w 30 ; For INTEL Platform, Put system to S4 after 5 sec, then wake after 30 sec.
pwrtest -s3 -t 5 -w 30 ; For INTEL Platform, Put system to S3 after 5 sec, then wake after 30 sec.
pwrtest -r ; Warm boot
pwrtest -cb ; Cold boot
[註]
- S3 功能只能喚醒系統，喚醒後會當機，因為我沒有支援Reset Vector(Not support)
- 有些系統S4/S5 並不支援RTC wake up，所以請跟你們的BIOS/EC確認，因為這個工具只是去填RTC Enable bit & RTC Alarm interrupt而已。

如何透過DevCon.exe 去開跟關你的Device Manager內的設備
如何透過DevCon.exe 去開跟關你的Device Manager內的設備
當你安裝WDK, Visual Studio 或是Windows SDK時，這些安裝檔裡面就會包含DevCon.exe。
我的DevCon.exe是在底下這個路徑內找到的:
C:\Program Files (x86)\Windows Kits\10\Tools\x64\DevCon.exe
當然，如果你想要自己Build source code的話，你也可以從底下的路徑找到這個source code:
https://github.com/Microsoft/Windows-driver-samples/tree/master/setup/devcon
我自己也用VS2013 成功建構出來這個執行檔，只是有個小地方要注意，就是你build code之前，要用command prompt(Build environment)先執行底下的指令，先把msg.h 建立出來，不然你沒辦法用專案檔案去compiler , 因為會出現會找不到msg.h的ERROR.
C:\DevCon > mc msg.mc 會產生msg.h
底下就是一些基本的指令操作:
1)先找你要開關的Device的HWID(我是存到一個文字檔慢慢找):
devcon hwids * > D:\hwids.txt
2) 使用底下指令去disable , 記得在HW ID前面加@
devcon /r disable "@ACPI\DELL0812\3&31FF937C&0"
3) 使用底下指令去enable, 記得在HW ID前面加@，然後HWID要用" "包起來.
devcon /r enable "@ACPI\DELL0812\3&31FF937C&0"
4) 使用底下指令去重新scan hardware
devcon rescan
5) 使用底下指令可以做重新開機動作
devcon reboot
至於其他跟寫driver時會用到的指令功能，大家就看底下微軟的詳細說明囉~
