The Redmond-based company’s upcoming Windows 8 OS will have to build upon a power efficient system, especially when most developers and manufacturers plan to place the operating system on tablets.

With that in mind, Microsoft intends to create Windows 8 apps that do not dissipate the juice out of the laptop battery for Toshiba if these are only running in the background.

Based on the company’s statement, Windows 8 is set to enhance code execution of background applications, which allegedly will reduce the rate of power consumption while keeping the multitasking function in hand.

“Minimizing the power consumption of your PC while maximizing the responsiveness and utility (making it “fast and fluid”), is a significant engineering challenge,” said Sharif Farag and Ben Srour, Lead Program Managers on the Fundamentals and User Experience teams of Microsoft, respectively.

“While it starts with the work we do in Windows to provide support for the right level resource usage, this work requires developers to take resource utilization into account as they develop their apps.”

Microsoft built a new set of APIs (application programming interfaces) dedicated to background processes that will give multitasking abilities for users to minimize power consumption. Laptop battery for HP.

Both managers said that the company’s aim is to get the processor into much lower power states for most of the time, which means suspended apps will stack away in cache.

“Power efficiency applies to all form factors and all usage scenarios—using less power is the right thing to do for everyone. This is an area of significant innovation for Windows 8 PCs, and builds on the foundation of the new runtime model in WinRT—it is not the sort of thing you can retrofit onto existing desktop applications while still maintaining functionality and compatibility,” they added.

According to Microsoft, the switch for a suspended app happens automatically such that it saves the last state for the next use.

However, not all applications will go to the main memory’s cache because of storage space limitations, so the memory manager of Windows 8 will have to choose on sticking seldom-used applications back to the disk, which is likely to be a solid-state disk (SSD) instead of a conventional hard drive for tablets.

Farag and Srour said, “To this end, we have added a new component to Windows 8 called the “Desktop Activity Moderator,” which only runs on these new connected standby-capable platforms. This component is designed to help reduce the resource utilization of desktop apps when the device goes into connected standby. If we allowed apps to continue running unchecked in this low-power mode, the PC would run down the battery more quickly. Instead, we suspend desktop applications, stopping their resource use and maximizing battery life. From the applications’ perspective, it will appear as if the PC has simply been put to sleep. When the PC is woken from connected standby, the app will resume as if the PC had been woken from a sleep state.” Laptop battery for Acer

To maximize the Windows 8 potential, Microsoft needs to find the right tablet makers who can unleash the full potential of its upcoming OS in order to rival the Apple iPad and Android tablets.
