GPS stays on after going into standby

[joshkeller77]

This would be really useful if it works, especially for those people who can't get aGPS so they don't have to lock after backlight goes out.

Could someone test and see if these settings actually work? I am going to be busy tomorrow and won't have any time, but would love to see if it actually works.

If you don't know what you are doing please be careful, at least back up your registry keys before deleting them.

In the registry I found these settings for power management.

[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Contro l\Power\Interfaces]
"{EB91C7C9-8BF6-4a2d-9AB8-69724EED97D1}"="Power-manageable display"
"{98C5250D-C29A-4985-AE5F-AFE5367E5006}"="Power-manageable NDIS miniports"
"{8DD679CE-8AB4-43c8-A14A-EA4963FAA715}"="Power-manageable block devices"
"{A32942B7-920C-486b-B0E6-92A702A99B35}"="Generic power-manageable devices"

Each one of the {} strings are an IClass for other device including the GPS. The one found in the GPS was this "{A32942B7-920C-486b-B0E6-92A702A99B35}. When I deleted the IClass string out of the following keys, you are now able to put your phone to standby and the GPS will keep running.

[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\GPSID]
"IClass"="{A32942B7-920C-486b-B0E6-92A702A99B35}"


[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\SerialGPS]
"IClass"="{A32942B7-920C-486b-B0E6-92A702A99B35}"
