I bought a little system to run as a router/firewall by Jetway that had a Celeron N2930 CPU a couple years back. This system was pretty great, silent and more than fast enough for my 1Gbps internet speed. Then, it all of a sudden shut off and would no longer power on again.
I've since replaced it with a HP T620PLUS and happy with that. But as I was thinking about what to do with the dead N2930 system, I thought I'd do a search online to see if someone else might have had a similar failure, and then I came across some posts about various CPU failures including the N2930. And then, I found this document by Intel:

Anyone with J1800, J1900, N2807, and N2930 may want to take notice....

The mention of LPC sounds familiar... Atom C2000 AVR54?Page 11, section 5.0:
5.1 VLPI1. System May Experience Inability to Boot or May Cease Operation
Problem: Under certain conditions where activity is high for several years the LPC, USB (low speed and full speed) and SD Card circuitry may stop functioning in the outer years of use.
Implication: LPC circuitry that stops functioning may cause operation to cease or inability to boot. SD Card or USB circuitry that stops functioning may cause SD Cards to be unrecognized or Low Speed or Full Speed USB devices to not function. Intel has only observed this behavior in simulation. Designs that implement the LPC interface at the 1.8V signal voltage are not affected by the LPC part of this erratum.
Workaround: Firmware code changes for LPC circuitry and mitigations for SD Card & USB circuitry have been identified and may be implemented for this erratum. Status: For the steppings affected, see the Summary Tables of Changes.
