Questions regarding registry settings in custom OEM

[Ryan07]

I have a HUGE custom RGU file that pretty much makes my 6700 ready to go when I hard reset. There are only two things that I can't get to work and I'd like some advice.

First, in Start > Settings > System > Power > Advanced
I want to uncheck the On External Power box. I have the backlight settings working properly to dim the screen after one minute on AC power. I do want the device to suspend on battery after 1 minute and that is working.

[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Power\Timeouts]
	"ACResumingSuspendTimeout"=dword:0000000f
	"ACSuspendTimeout"=dword:00000000
	"ACUserIdle"=dword:00000000
	"BatteryPoll"=dword:00001388
	"BattResumingSuspendTimeout"=dword:0000000f
	"BattSuspendTimeout"=dword:0000003c
	"BattUserIdle"=dword:00000000

The ACSuspendTimeout shows as 0 which should be unchecked but on a hard reset it is set to 30 minutes and remains checked. Am I in the right place for this? Can I add a value called "ACTimeoutChecked" like in the backlight settings perhaps?

The backlight settings work fine. It is disabled for battery and blanks the screen without suspend for AC power.

[HKEY_CURRENT_USER\ControlPanel\BackLight]
	"ACTimeout"=dword:0000003c
	"ACTimeoutUnchecked"=dword:00000000
	"BatteryTimeout"=dword:00000000
	"BatteryTimeoutUnchecked"=dword:0000001e
	"QKeyLedOnOff"=dword:00000001
	"QKeyLedTimeout"=dword:0000000a
	"DefaultACBrightness"=dword:0000000a
	"DefaultBrightness"=dword:00000008
	"ACBacklightOnTap"=dword:00000001
	"BacklightOnTap"=dword:00000001
	"ACBrightness"=dword:0000000a
	"Brightness"=dword:00000008
	"AutoMode"=dword:00000000
	"OnOffBatt"=dword:00000001
	"OnOffAC"=dword:00000001
	"OnOff"=dword:00000001
	"BatteryTimeoutChecked"=dword:00000001
	"BatteryTimeoutTemp"=dword:00000000
	"ACTimeoutChecked"=dword:00000000
	"ACTimeoutTemp"=dword:00000000

The last question I have is about the Start > Settings > Personal > Menu
I would like to know if I can uncheck all of the boxes through the registry or rather set a value to uncheck them for me. I have no idea where to look for this portion.

Thanks for the time.
