So try this Group Policy method to see if it works for you. Some users have tried adjusting the settings in the Group Policy (gpedit.msc > Computer Configuration > Windows Settings > Security Settings > Local Policies > Security Options, Microsoft Network Server: Amount of idle time required before suspending session) and found that adjusting this setting didn't fix the problem for some users but it did fix the problem for a few. This is because of an addition of email accounts to the Mail app in Windows 8, causing certain security policies to be enforced by Exchange and resulting in the computer locking after a few minutes of inactivity. The first solution involves resetting your security policies (User Accounts > Reset security policies). While Microsoft hasn't clearly identified this as a bug or offered a solution just yet, there are a few methods that may work for those of you who are experiencing the same problem. Microsoft's solution to this problem is to do a system refresh or complete reset of the device, which isn't a practical idea. A few suggestions appeared on the support forum asking users to change the power plan, and even disconnect/reconnect the power supply, to no avail.
Windows 8 sleep mode settings pro#
No matter what the power plan is configured to, the Surface Pro seems to enter sleep mode within a few minutes. I double checked my power options I have my current power plan (based off Balanced) set to put my Surface Pro to sleep (while plugged in) after 30 minutes of being idle!" one user stated on an official Microsoft support forum. I noticed this when reading some news on the internet.
Windows 8 sleep mode settings software#
"One of the software issues I've been experiencing is that when my Surface Pro first goes to sleep after a restart and I wake it up, it then begins going into sleep mode every like 1-2 minutes of being idle. However, Surface Pro owners are still experiencing a bug that causes the device to sleep after a few minutes of idling, even when the power options clearly specify a different power plan. Microsoft has been consistent with firmware updates for the Surface Pro since the release of the device back in February of this year, with the exception of just one month.
