Accessories The Surface Pro 3 is the third-generation Surface-series 2-in-1 detachable, designed, developed, marketed, and produced by Microsoft.

[9] On October 6, 2015, Microsoft released its successor, the Surface Pro 4 with a bigger screen with a higher resolution and reduced bezels, faster CPU options, a thinner body and improved cooling system.

The Surface Pro 3 has a body made of magnesium alloy giving a gray matted finish to the back of the device.

It includes a USB 3.0 port and a Mini DisplayPort on the right, an audio jack on the left, and a hot swap microSD slot on the back of the device.

The Surface Pro 3 is one of the first 64-bit Windows devices that features InstantGo (formerly Connected Standby),[14] allowing for smartphone-type power management capabilities.

This allows for Windows Store apps to update info (such as email) while the device appears off, and for the operating system to run automatic maintenance when connected to AC.

David Pogue suggested "The upshot is that, with hardly any thickness or weight penalty, the kickstand and the Type Cover let you transform your 1.8-pound tablet into an actual, fast, luxury laptop".

Pogue also stated that the new multi-stage kickstand, 3:2 screen aspect ratio, and new Type Cover 3 detachable keyboard made it a competent laptop.

[25] The Surface Pro 3 received a repairability score of 1/10 from iFixit because of the use of a strong adhesive material throughout and the difficulty in removing the display.
