It seems Microsoft’s newly announced Surface Pro laptops are giving users a hard time. More than 300 customers have taken onto Microsoft’s support forums complaining about unexpected shutdowns. Microsoft says it’s aware of the problem and ‘is investigating this issue’.

We are aware of a small group of customers reporting a scenario with their new Surface Pro in which the device inadvertently hibernates,” said Microsoft in a statement.

Sources indicate that many users are experiencing the same type of problem on a frequent basis. It has been long known that issues started cropping up since the time Microsoft adopted Intel’s Skylake processors in 2015.

After which, complaints started flooding in about laptops suddenly shutting down and crashing displays. That time, the company tried to fix those issues by detailing temporary solutions to the problem, though they did not work effectively.

But having said that, some users were constantly exposed to problems while others users had no problems whatsoever. However, there still are a lot of questions over reliability and credibility of Surface laptops.

And it seems some Microsoft Surface Pro owners are now facing the problem of sudden shutdowns. However, Microsoft suggests that the Surface Pros are hibernating instead of shutting down.

Microsoft MVP Barb Bowman now recommends Surface Pro users who are facing the issue to return the device as soon as possible, while they’re still in a brand new condition.

It has historically taken Microsoft months and months to identify issues and come out with a fix,” she writes. “[If you don’t exchange the device now] 6 months down the road, Microsoft will exchange for a refurb if they determine it is a hardware issue and the quality of the refurbs has not been consistent,” further adds Bowman.

Put simply, Microsoft will readily replace the affected Surface Pro unit while they’re still new with a brand new unit. For users who are experiencing the same issue and purchased the Surface Pro a long time back, they’ll be entitled to get a refurbished unit of the Surface Pro.
