It seems that some new Surface Pro owners have been troubled by a bug that is causing their Surface Pros to randomly enter sleep mode without warning, resulting in lost data for the owners.
ZDNet writes that reports first started to emerge about the sleep issue a short time after the new Surface Pro was released, with users posting on Reddit and on Microsoft’s support page that their new Surface Pro tablets were prone to powering down suddenly when being used. The first person to actually report the issue on Microsoft’s support forums said that they lost schoolwork because of the sudden shutdown.
Someone from the Microsoft support team has now posted on the official forum about the issue, reassuring those affected that a fix is on the way soon:
“We believe we have identified the issue, and are currently testing a fix that will be delivered via Windows Update,” said the Microsoft official.
This comment was then followed up by another post that said that the fix is still being tested and therefore was not ready for this week’s Patch Tuesday update.
