Microsoft released an update today to Surface Book and Surface Pro 4 users that users of these devices have been longing for for months now.

An example of the power management issue is when the user puts the device to sleep, puts it in a bag, and when he removes it from the bag, the device is piping hot as if it had been used the whole time. This issue also drains battery life.

I know that everyone is very excited about this update, so without further delay, here is what got updated in the Surface Book firmware update:

Microsoft also notes:

When Surface updates are provided via the Windows Update service, they are delivered in stages to Surface customers. As a result, not every Surface will receive the update at the same time, but the update will be delivered to all devices. If you have not received the update then please manually check Windows Update later.

Many fans flocked to the Surface Book when it came out. It was Microsoft's first laptop. They flocked to it for the same reason that Android fans flock to Nexus devices. Having a first party device makes you feel like you're experiencing the OS in the way that it was meant to be.

After spending anywhere between $1,499 and $3,199 on a Surface Book, many were disappointed with the experience that they received for the hefty price tag. Hopefully, this update will fix the issues that users of both Surface Book and Surface Pro 4 have had.
