SurfaceBook Crashes/Shutdowns During Sleep

My unit was manufactured in April and has the Sleep of Death issue.

Hardware was my gut feeling and became my hope when able to exchange for a late-model.

As I said, having had a few friendly visits to the same MS store helped in that they knew I was at least reasonably proficient at thoroughly testing and have product knowledge, but ultimately I believe the factors in an exchange for a new-new SB are:

1.) Buy Surfaces from a MS Store (or at minimum, direct from Microsoft online) as MS Stores are the only places to provide more-or-less full service for this product line. That would include the possibility of insisting on a new-new Surface and having a chance at actually getting one.

2.) Be nice. Be friendly. The store employees, like all retail folk, are bombarded by ignorant, rude people demanding things they have no or little understanding of all day, so strive to show the opposite even when you're frustrated.

3.) Prepare to offer a detailed and thorough analysis of what you've experienced, prior efforts to resolve, and have your machine's logs to show in case they should like to look. Willingness to show even just Event Viewer logs helps illustrate you might know what you're talking about. I'd recommend having the event logs illustrating the sequence of events surrounding the issue you're experiencing, which should look near-identical to what has been posted here and many other forums/threads. Your SB Serial Number should lead to your manufacture date. After making your case, request what you'd like firmly but politely...possibly while holding a rabbit's foot.

4.) Be thankful you live near a MS Store. I'm not sure what to advise if you don't, but we all have a 1 year warranty from date of purchase, so theoretically I'd like to think it's not impossible to do the above via telephone. https://www.microsoft.com/surface/en-us/support/warranty-service-and-recovery/surface-warranty

SB i7 with dGPU. I could easily buy that it's a, if not THE, culprit. Not sure if I bookmarked the source, but seem to remember reading somewhere about the custom GPU being updated at pretty low level (not sure if it was hardware level or otherwise).

From all this evidence, it seems to me that this sleep-crash issue is coming from a hardware issue, since Microsoft has not been able to fix it for months. How were you able to acquire a replacement that was newly manufactured? I really need a surface book that doesn't crash overnight.

Does your SB have the nVidia GPU or not?

When I disconnect my screen, things are much better (almost perfect). Only when the GPU is involved in things do I have issues (sleep, external display issues, etc.).
