Best Practices for Faster Suspend Times (Windows Embedded CE 6.0)

1/6/2010

Only after passing the battery level test are devices that consume significant power turned on by Power Manager.

Do the following to achieve faster suspend times:

• After suspend is initiated, ignore the suspend button until a PBT_RESUME notification arrives.
• In the battery driver, implement the cache flag in the GetSystemPowerStatusEx2 function.
• Choose a high enough battery critical level so that the system does not reduce power unexpectedly if a device is turned on.

You can configure the system to return from PowerOffSystem, and then go right back to sleep if the battery is critically low.
