Contents 1 History 2 Features 2.1 Hardware 2.2 Software 2.3 Accessories 3 Reception 4 Timeline 5 References History The Surface Pro 4 was announced on October 6, 2015 alongside the Surface Book. Both devices were available for pre-order the following day and available for customers beginning on October 26, 2015. The device initially exhibited failure to sleep properly, which drained the battery very quickly. Microsoft subsequently developed a fix that was made available on February 17, 2016. Features Hardware The Surface Pro 4 is the same size as the Surface Pro 3, but has a thinner screen bezel which allows for a display of a slightly greater size of 12.3 inches ( 31 cm ). The screen resolution is also greater than the Surface Pro 3 's, at 2736x1824 at 267 PPI, with the same aspect ratio of 3 : 2 and 10 - point multi-touch. The chassis is 0.03 inches ( 0.76 mm ) thinner and 0.03 pounds ( 14 g ) lighter than the Surface Pro 3. The cooling system of the 2 - in - 1 has been redesigned and dubbed hybrid liquid cooling system. It includes heat pipes with a flowing liquid, which is meant to avoid the use of the internal fan when the device is used for less demanding tasks such as web browsing. All Surface Pro 4 models feature 6th - generation Skylake Intel Core processors -- m3, i5 or i7 -- which are more powerful and run cooler over its Intel Core Haswell predecessors found in the Surface Pro 3 and 2. The maximum clock rate of the most powerful CPU option ( i7 - 6650U ) is also greater at 2.2 GHz, with up to 3.4 GHz in the Turbo Boost mode. The m3 - powered model is completely fanless. RAM and SSD options available are 4, 8, 16 GB and 128, 256, 512, 1024 GB respectively ; the top options are two times as capacious compared to top options of the Surface Pro 4 's two recent predecessors. The common traits, inherited from the previous generation device, are a continuous kickstand, magnesium casing with a silver - colored back side, 802.11 a / b / g / n / ac Wi - Fi radio, Bluetooth 4.0 Low Energy, full - size USB 3.0 port, microSD card reader, headset jack, Mini DisplayPort, Cover Port, and a renamed SurfaceConnect, a port on the side to connect a wall charger, Docking Station or Surface Dock accessories.

Windows 10 comes pre-installed with Mail, Calendar, People, Xbox ( app ), Photos, Movies and TV, Groove, and Microsoft Edge. With Windows 10 the Tablet mode is available when the Type Cover is detached from the device. In this mode, all windows are opened full - screen and the interface becomes more touch - centric. The device also has a Windows Hello - compatible camera. It combines the use of a regular and infrared cameras to authenticate the user. Accessories The Surface Pro 4 is backward compatible with all accessories of its predecessor. At the Windows 10 Devices Event on 6 October, 2015, alongside new Surface 2 - in - 1s, new accessories were announced. The Surface Dock is a redesigned docking accessory in a brick form factor. It is compatible with all past and future Surface models with a SurfaceConnect side port, previously used to connect a wall charger or Docking Station accessory : Surface Pro 3, 4 and Surface Book. The Surface Dock will have 2 Mini DisplayPorts, 1 Gigabit Ethernet, 4 USB 3.0, and 1 audio out ports. Although Surface Pro 4 is backward compatible with Type Cover accessory of Surface Pro 3, an attachable keyboard which doubles as a screen protector, the Surface Pro 4 Type Cover has been announced with and without a fingerprint ID sensor. The new Type Cover is thinner and lighter than its predecessor, has improved magnetic stability for lap use, a mechanical keyboard with improved key spacing, as well as a larger touchpad. An updated version of Surface Pen is included with the Surface Pro 4, which has 1024 levels of pressure sensitivity and is heavier with a rubberized tip. However, the new pen has only one button on the side rather than the previous pen 's two. There is a eraser on the end that doubles as a button, which may perform different tasks, like opening the OneNote app or activating Cortana, and can be customized using the Surface App. Reception The Surface Pro 4 received generally positive reviews from technology critics. Most praise a sharper and larger display compared to the one found in the predecessor, redesigned cooling system, improved technical specifications, and an improved Type Cover. The common disadvantages found by reviewers were that the Type Cover is still a separate purchase, the relatively modest performance of the Intel Core m3 chip, and modest battery life.
