While Microsoft’s response to the SIMPLO issue has been restricted to “working on a possible software fix”, customers are starting to report that even when plugged in, their SP3 tablets shut down. In essence, they can’t use their Surface Pro 3’s at all. This seems to happen when the amount of usable battery fully charged falls below a certain point, and as the days continue without a fix, more and more customers will have unusable devices. I don’t see that they will be able to keep their devices running long enough to even apply a software fix, should one actually become available. These customers are trapped. Microsoft won’t swap them out, and some are paying the usurious $450 out of warranty exchange fee. Note that Microsoft committed to a $200 battery replacement program on a Reddit AMA https://www.reddit.com/r/IAmA/comments/26m9cu/we_are_panos_panay_and_the_surface_team_at/chsei5u but has refused to honor this or even comment on it. (And as an aside, Apple charges $129 to replace an out of warranty battery.)
Microsoft told customers in the same Reddit AMA https://www.reddit.com/r/IAmA/comments/26m9cu/we_are_panos_panay_and_the_surface_team_at/chse7pn that “the battery can get charged daily (5 days a week) for over 4.5 years and still maintain 80% capacity”. Again, customers are responding in the thread that they can’t even use their devices while connected or docked.
I checked my sent email and note that as a Community Forum Moderator that I brought it to the attention of Microsoft on March 3, 2016. And a couple of times thereafter. I saw the trending that early.
And as of Saturday, March 6, afflicted Microsoft customers have not had a single update on the situation since the initial “we think we can fix in software and are working on a fix”.
