Piling on here - exact same issue that just took a while longer to emerge. Shameful that Msft didn't immediately recall all these
Sur-feces or even notify customers about this well documented and proven design flaw, Not surprising though from a bad faith company like Msft.
I thought I was doing something wrong till I reported frequent shut downs to my IT folks and they classified my ticket under "expanding battery". Turns out ALL the many thousands of these SB2's we bought eventually had the same problem. My non-Msft replacement is on the way and I hope we're able to get some resolution from Msft though I highly doubt we will.
