Resolving the endurance of WinRT 8.1 after re-stacking

Surface RT users did not go smoothly during the update of Windows RT 8.1. In addition to the initial withdrawal of Windows RT 8.1 by Microsoft, Microsoft has now discovered Surface RT ( Now I should change the battery life after the Windows RT 8.1 update, and give the repair steps. Currently, I only found the user who installed the RT 8.1 preview to upgrade to the official version.

Microsoft has released the reason for this battery life problem: "In the upgrade process, the wireless adapter power policy has not been migrated to the new environment, but is set to the default policy (incorrect settings), This will consume more power when using or online standby. Here are the steps to fix the battery life problem provided by Microsoft:

1. Start button position in the lower left corner, right click, select “Command prompt (admin) ”

2. Enter The following command is executed:

powercfg -setdcvalueindex SCHEME_CURRENT 19cbb8fa-5279-450e-9fac-8a3d5fedd0c1 12bbebe6-58d6-4636-95bb-3217ef867c1a 3

3. Enter the following command to enter:

powercfg -setactive scheme_current

Oddly enough, the method Microsoft gave is hidden in the battery and power support page of Surface RT. It is not easy to find. At present, Microsoft has not released a system update. Fix this problem.
