The specification describes a Microsoft proprietary standard for Windows 8 software and hardware that developers and hardware vendors can optionally comply with to enable devices to be turned on and off instantly. It also allows the
operating system to continue performing background tasks, such as updating content from apps, when a device is not being used. Devices must be able to turn on in less than 500 milliseconds. The hardware requirements extend to battery life, in that systems must not drain more than 5% of battery capacity while idle over a 16-hour period. It requires the following: • A firmware flag indicating support for the standard • The boot volume must not use a
hard disk drive • Support for
NDIS 6.30 by all network devices • Passive cooling on standby •
Trusted Platform Module 2.0 • CPU, chipset and BIOS support for
S0ix "Low Power S0 Idle" power state • All peripheral devices and drivers must support D3cold On Windows 8.1, supporting InstantGo and having a
Trusted Platform Module (TPM) 2.0 chip will allow the device to use a passive
device encryption system. Compliant platforms also enables full
BitLocker Device encryption. A background service that encrypts the whole system which can be found in 'Windows Security'>'Device Encryption' page in
Windows 10 and 11. ==Limitations==
