SG-5100 cold boot issue
-
By default it should immediately power up an boot from cold. However there are BIOS options to control that behaviour. You might try defaulting the BIOS setup options to be sure. I could just about imagine something got set somehow. It seems unlikely though.
-
@stephenw10 it looks like it is a failing eMMC (the mmc test utility returns that the life time estimation is '0x0b' for both type a and type b. Am I right in understanding that the only solution is to find someone who is able to remove the eMMC from the board?
-
Yes, as far as I know that's the only solution if the eMMC has failed entirely.
-
I did not know that removing it would work. I will keep that in my back pocket in case my 5100 eMMC fails, although I installed an SSD early on and it boots from it, so I don't know if there is much danger of it going belly up.

@Phizix If you are using the SSD for storage then you cannot be using the eMMC and you needn't be concerned.

@stephenw10 I've found someone who has been able to use a reworking station to remove the eMMC, and I've installed a SATA SSD, put the power back in and tried switching the power switch (both with and without the PFSense install USB inserted) and am getting no console output, and the power switch LED is staying red. The status LEDs are not illuminating. Any idea what I am doing wrong, or what I should try? Thanks again.
-
Does it eventually power on? Or power on as expected from cold as it did before?
I have no solution here. It sounds as though it may not have been the eMMC. Or that other damage was caused during the removal.
-
@stephenw10 It's infuriatingly intermittent and confusing. It does not ever get to the booting stage on its own (or at least not as long as I've left it). Just after posting this, I tried holding the reset button down for 30 seconds without power, then holding it and the power button down for 30 seconds once the power cable was in, and then after that it booted and I was able to install to the SSD! Then it went to reboot back into the system, the power switch stayed green, but I got no more console output, and the power switch wouldn't allow a graceful shutdown. I pulled the power cable, and I'm back to square one.
-
@Garbo (the trick just seems to be holding the power button for 30 seconds, and then pressing it again. I'll see how long this works! Any idea what that would be about?)
-
The behaviour sounds like a bad capacitor in the power circuitry but that's just a guess. I would check for any obviously bad caps though.
