According to ZDNet’s Mary Jo Foley, a Microsoft spokesperson confirmed that the update fixes the battery charging issue that some Surface Pro 3 units had since last month, while also adding overall performance enhancements. The update should be available to new Surface Pro 3 owners as soon as they set up the tablet.
Microsoft will offer the Surface Pro 3 in five different configurations: 64GB / Intel i3 ($799), 128GB / Intel i5 ($999), 256GB / Intel i5 ($1,299), 256GB / Intel i7 ($1,549), and 512GB / Intel i7 ($1,949). Only the Intel i5 variants are shipping this month, with the other three expected to arrive in August.
Running Windows 8.1 Pro and featuring a 12-inch display with 2,160 x 1,440 pixels, the Surface Pro 3 is marketed by Microsoft as a tablet that can replace your laptop.
