Hello. Recently I have installed an intel 530 series 120G ssd into my ASUS ROG G550JK laptop instead of the built-in hdd. I did a clean windows 10 install, installed all the necessary drivers and updates. The problem is my laptop reboots on resuming from sleep mode. It doesn't show a BSOD, so no memory dump is created. It just reboots. The laptop does go into sleep mode since the led periodically blinks as it should when the laptop is in sleep mode. The event viewer shows a critical event (Source: Kernel-Power, Event ID: 41, The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.) I can provide any additional info if necessary. The BIOS is of the latest available version. I'm not sure if it's a malfunctioning ssd, or a firmware bug, or maybe this ssd is incompatible with this laptop model. Thanks.

Dmitry.

UPDATE

I asked the same question on the intel ssd support forum and I got a response saying that "... The Intel® SSD 530 Series has new low power features designed for Ultrabooks and low consumptions PC's, this includes the DevSleep functionality.

The SSD itself does not require any special driver nor configuration, however, some older systems may not be fully compatible with newer power saving features. We advise you to check the Computer Manufacturer Support Websites, confirm that you are using the most recent BIOS available for your PC, as well as updated chipset/storage controller drivers, also, check with them if your system supports Devsleep.

In some cases, you may be able to prevent this type of issue by disabling fast boot or other similar technologies in the BIOS. ..."

Can DevSlp support be enabled by a BIOS update and if so, can we expect such an update?

P.S. Disabling FastBoot didn't resolve the issue

UPDATE #2

Check out this (https://communities.intel.com/thread/97372) post. Although, I can't check if it helps myself now.

Did you ever contact ASUS support regarding this issue? I'm sure there's a way for ASUS to create a BIOS to fix the compatibility issue for this SSD and it may also fix the issue for other low power SSDs.

Yep, I did. I'm waiting for a response now. I hope it can be fixed with a BIOS update.

This is what I've read on the wiki page (https://en.wikipedia.org/wiki/DevSlp) today. " ... Due to the way they work, DevSleep-enabled drives may not be suitable for most desktop PCs and some notebooks with the 3.3 V voltage present in their SATA power connectors; the presence of 3.3 V results in DevSleep-enabled drives remaining in DevSlp state. An incompatibility between a desktop mainboard and a SATA SSD may be resolved by disabling the DevSleep feature using a power connector adapter that does not pass the +3.3 V line. ... ". I guess it means this issue cannot be resolved by a BIOS update and the only way is to disable the devsleep using the way described here (https://communities.intel.com/thread/97372) or am I wrong?

I have solved the issue. Turned out it was completely unrelated to the DevSleep functionality of the SSD. All I had to do was to downgrade BIOS and then upgrade it back (even though I had the latest available version flashed). The instruction is here (http://www.ahowto.net/windows/downgrading-asus-notebook-bios/).
