My ThinkPad W541 crashes and restarts on an almost daily basis now.
In Windows 10, if I go to View Event Logs -> Windows Logs -> System I see Critical events with Kernel-Power is the source:
I'm also seeing lots of WHEA-Logger entries:
A corrected hardware error has occurred. Reported by component: Processor Core Error Source: Corrected Machine Check Error Type: Internal parity error Processor APIC ID: 4 The details view of this entry contains further information.
https://social.technet.microsoft.com/wiki/contents/articles/3567.event-id-18-microsoft-windows-whea-... discusses this error some but pretty much says the error can come from anywhere.
I tried to do a ram test with Windows Memory Diagnostic Tool and that didn't show any RAM issues so I have no clue. I was thinking the easiest thing to do now would to send it to the depot for diagnostic / repair (it's still under warranty).
The problem I have with that proposal is two fold.

I'm wondering if it could be that the CPU is just overheating. I used CPUID HWMonitor Pro and it seems like it's running fairly hot pretty consistently, as the attached image shows for a random 5 minute interval.
The CPU utilization averages at around maybe 17% with a few one off peaks up to 50%. I'd post a pic of that but it looks like I can only do one attachment per post..

Temperatures look too high, but I think they are not high enough to cause your symptoms

If you open the Lenovo Solution Center, it will tell you how much of your warranty is left:
