Last month, we reported that some of the review units of Surface Pro 3 are facing a battery charging issue in which the device won’t turn on even when connected to the charger. Microsoft then acknowledged the issue and confirmed that Microsoft is working on the fix that will be delivered via update soon. Today, Microsoft delivered this update via Windows Update. Mary Jo Foley confirmed that her review unit received this update today. Microsoft told her that this update fixes the power issue and also contains number of performance improvements as well. The device will be available in the retail in US from tomorrow.
