Open up the Power Management Control Panel and select Change Power Settings, Then select Change Advanced Power Settings, and look under PCI Express...expand under Link State Power Management.... and look under On Battery and make sure that it is set to Maximum Power Savings. The was a bug in one of the updates that made Power Savings set that setting to Off. If that is the case it would manifest the symptoms you're describing...
Guys, i just downloaded the January2014SurfacePro2.zip 158.1 MB but no idea how i can manually install this.
Can i get some help?
Maybe a manual installation will fix it!

Ok. Create a new Power Plan:
- Start > type: Power Option > Enter
- Then click on Create a power plan on the left side column
- Select Balance, and Enter a name like "Extended Battery Life" or something.
- Then click on Next and Create.
- Then click on Change plan settings for it, and then change advance power settings.
Now, configure the power plan to be extra power saving for every option.
Once done, set it, and see if your problem is still there.
