Surface Book 3 completely bricked after Windows Update — no resolution, no response from escalation

Hi,

I'm posting here because I've completely exhausted private support channels and received no resolution — or even a response — from Microsoft.

My Surface Book 3 (13.5", i7, 16 GB) became entirely unresponsive immediately after a Windows update. No display, no fan, no sound, no reaction to any buttons. The only sign of life is the light on the charger. This is the second time such a failure happened after an update — the first time it eventually revived after several days. This time, nothing.

I've contacted Microsoft support, and the case was escalated on July 3rd. I responded to the escalation team, laid out the full history, and proposed either a repair subsidy or a trade-in with meaningful credit toward a new Surface device.

Since then: complete silence. I’ve sent polite follow-ups — nothing.

I know this is a known issue with Surface Book devices — there are many reports online of firmware or UEFI corruption following updates. My device was working perfectly before the update. I’ve already had to replace it once due to a battery failure under warranty. I’m not asking for anything unreasonable — just a response and a fair resolution for a problem caused by Microsoft’s own update.

If anyone from Microsoft Community Support can help push this case forward, I would deeply appreciate it.

Case reference available if needed.
