How to turn off devsleep function so my 535 SSD can be recognized in BIOS?

[AMill27]

Didn't have this issue until a few months ago, everytime I need to start my computer and recognize my boot drive, I need to either clear CMOS, or restore default settings. I noticed another closed thread that apparently had a link to solve this problem, but Intel sent it out in private messages. The link seemed to work for some people, and I would like it as well if possible.

Thanks,

Andrew

Hi Andrew,

Thank you for posting in the Intel® communities.

Below are the instructions to flash your drive with a new firmware version that will disable the DevSleep feature. Please follow these steps and let me know if it worked.

1. Download the issdfut_2.0.15.iso file from the following site: https://downloadcenter.intel.com/download/25348
2. Go to the following site and download the Rufus software https://rufus.akeo.ie/
3. Connect an empty USB flash drive to the PC.
4. Open Rufus and change only the option Device and select your USB. Then go to ISO image, click on Search and select the issdfut_2.0.15.iso image.
5. Go to your BIOS -> Boot -> Boot priority and select the USB flash drive as primary boot device.
6. Re-boot your PC. It should boot from the USB flash drive and enter into the firmware update tool for your SSD.
7. Update the firmware and then boot windows.
8. If it does not boot into the USB flash drive or it gives you an error, please go to BIOS and change the boot mode to Legacy Only. Then try again.

Please try this process and let me know the results.

Have a nice day.

The first time I tried to reboot, it said "an operating system isn't found" but I have a purchased copy of Windows 10 installed. Get Outlook for Android<https://aka.ms/ghei36>

Hi Andrew,

Make sure the ISO image I indeed flashed into the USB flash drive. Otherwise, the system won’t find any OS to boot from.

Additionally, make sure you set the USB flash drive as the primary booting device.
