Solution to the Win8.1 surface power consumption too fast

How to solve Win8.1 make surfacert power consumption too fast? This question baffled a lot of surfacert users, Since the Windows8.1 beta release many users can not wait to try, because the beta version will have such a problem, because Surfacert also encountered embarrassing things, Win8.1 surfacert power consumption too fast, how to solve? Microsoft's work: Open Bluetooth can solve the problem of surfacert power consumption too fast.

How to solve Win8.1 so surface power consumption too fast to open Bluetooth can be solved

How to solve Win8.1 make surfacert power consumption too fast? This question baffled a lot of surfacert users, Since the Windows8.1 beta release many users can not wait to try, because the beta version will have such a problem, because Surfacert also encountered embarrassing things, Win8.1 surfacert power consumption too fast, how to solve? Microsoft's work: Open Bluetooth can solve the problem of surfacert power consumption too fast.

Does turning on Bluetooth really solve the problem of surfacert power consumption too fast? Fortunately, the tested Surfacert have said they can solve the problem. Here, small knitting to ask, why Win8.1 make surfacert power consumption too fast? I believe this is also a lot of netizens doubt it.

Microsoft's staff, of course, answered the question, according to Microsoft, explaining that Win8.1 causes Surfacert to consume too fast and how Bluetooth works in WIN8.1, in networked standby situations (such as screen closures), A specific UART controller will prevent the CPU from entering a low-power state, which is connected via Bluetooth. If you turn off Bluetooth in your PC settings, the system will continue to consume power.

So, turn on Bluetooth can solve Surfacert power consumption too fast problem.

OK, here's a review of the history of this issue:

Not long ago, the Windows8.1 preview has been on the test for some time, and some of the new adopters have installed the latest system on their Surfacert tablet machine. Because it is a test version, encountered problems will be unavoidable, so someone reflected, Surfacert upgraded to Windows8.1 after the battery power consumption too fast phenomenon.

Soon the Microsoft Support Forum also has the user response Surfacert this phenomenon, after installs the Windows8.1 preview version, own tablet machine even if in the standby situation also can consume 2%-3% electricity per hour. What led to the power consumption so fast is a drive: Microsoftuartv2driver (_SB. UAR3).

Then Microsoft Technical support staff suggested that the Surfacert Bluetooth can be turned on to solve this problem. The user then accepted the suggestion to enable the wireless Bluetooth of the tablet machine, and the problem of battery power consumption was solved.

Microsoft then explained why, because in a networked standby situation (such as a screen shutdown), Powerfg/sleepstudy would report to the system all problems that prevented the CPU from entering a low-power state, while a specific UART controller would prevent the CPU from entering a low-power state. This UART is connected via Bluetooth. If you turn off Bluetooth in your PC settings, the system will continue to consume power.

Microsoft is now aware of the problem and will be fully resolved in the Windows8.1rtm version.

"Summary of Small series"

OK, so far know how to solve the Win8.1 so that surfacert power consumption too fast phenomenon, the most effective and easiest way is to open Bluetooth can be solved. In fact, all software or system beta or preview version will have a lot of problems, for the sake of safety, we recommend waiting for the release of the official version, of course, eager to eat hot tofu students can also take the risk of using, but it is necessary to prepare for various problems.
