The Surface Pro 3 has been a steady product except for the several times it hasn’t been. This is another time that Microsoft’s updates have made it not a steady product.
The Windows 10 Anniversary Update has been going out to the Surface Pro 3 for a few weeks and what it left for those owning the convertible with an LG Chem-made battery.
What’s supposed to have been a firmware improvement has turned into a degradation as users found that the computer was not charging when plugged. Furthermore, when a Surface Pro 3 came off the power supply, it would instantly turn off. One user was reporting a full charge capacity of 144mAh compared to the design capacity of more than 42Wh after the update.
Some Surface owners with batteries supplied from SIMPLO have had tangentially similar problems with their cells for more than a month.
The issue has been acknowledged by Microsoft for nearly a week. No word on any solutions just yet.
