Fault symptom:
The Instant Go technology, originally called Connected Standby, is a brand new power management system for Windows 8 and Windows 8.1. That is, when the system enters sleep state, the application is in the suspend state, but it will still be connected to the network. That is to say, applications on the Metro UI will continuously update and receive new information, so that users can update information or applications on the device instantly and at any time, for example, e-mails and text message notifications, while traditional applications temporarily stop for Instant Go for power management purposes. The advantage of this new feature is just like that of a smartphone. Although the screen is closed or sleep, other applications continuously connect to the remote end with low power consumption, so that information will not be omitted or delayed. For example, mobile phone WeChat and QQ can still receive messages even if the mobile phone is locked.
Connected Standby is a logical power supply. Sleep is the Sleep status within the system. In Sleep state, the system does not execute any program. However, in the Connected Standby status, some applications, such as downloading files and playing music in the background, can still be executed under certain conditions.
Cause analysis:
TPM 2.0 is a prerequisite for InstantGo (Connected Standby, connection status Standby), allowing Windows 8.1 to extend device encryption to all versions of the operating system.
The new amd apu also supports Microsoft InstantGo technology, which can wake up the computer in a shorter period of time and ensure that data such as emails are continuously refreshed in standby mode. The two new processor families have also integrated the AMD development platform security processor based on ARM® Cortex®-A5 for the first time.

How to check whether the computer supports
1. How to identify whether the Windows 8 computer supports InstantGo? You only need to go to the device manager to check whether there are security devices.
Obviously this is 1.2, so it is not supported, but if it is 2.0, your Windows 8 computer will have the InstantGo function.
2. Run the powercfg/availablesleepstates command in the CMD window to determine whether your machine supports InstantGo.
When we execute this command on our computer, we will get an error message: "The system firmware does not support Standby status" (The system firmware does not support this standby state .). The host does not support this function.
Solution:
Turn off the computer with InstantGo
With InstantGo, you can use the latest applications and data to immediately wake up your computer from sleep. If you purchase a Windows 8.1 or Windows RT 8.1 computer with InstantGo, you can continue using the battery for a whole day without shutting down your computer completely. If you want to achieve this, you can perform this operation in a faster way:
1. Close all opened desktop applications, and the system will prompt you to save the work.
2. Long press the power button on the computer (about four seconds) until you can see "close the computer by sliding" on the screen ".
3. Then, slide down or drag the screen lock down with the mouse. If you have changed your mind, you can sweep up or drag the screen lock up with the mouse to return to the task being executed on your computer.
Lenovo and Microsoft supported models
Lenovo C445 uses amd apu and GPU, and supports Microsoft instantgo. AMD's product technology enables your device to instantly wake up within 500 milliseconds when you need it, this allows you to quickly return to your work status.
Surface Pro 2 supports the InstantGo function. However, InstantGo requires that the computer have TPM chips, while the Surface Pro in mainland China does not support InstantGo because it does not contain TPM chips for some reasons.
Winodws 8.1 Application
When the computer is completely shut down, the alarm will not sound. However, if your computer has InstantGo, the alarm clock can sound when your computer is asleep. Even if your computer is muted, your alarm will still sound.
To enable the alarm to sound when the computer is asleep, set the following permissions:
Turn on the "alarm clock ".
Sweep from the right edge of the screen to the center and click "set ".
(If you are using a mouse, point to the lower right corner of the screen, move the mouse pointer up, and then click "set ".
Click or click "permissions ".
Set "notification" and "lock screen" to "on ". This allows the application to display notifications, run in the background, and display the quick status on the screen lock.
