I installed Windows 10 onto my Intel 750 400GB(SSDPE2MW400G4R5-2.5" SSD version) last night and everything seemed fine but then this morning I
noticed that the HDD activity LED was on all the time. After spending about 4 hours on the problem I figured out that the LED works fine on other hard
drives but when I plug in the 750 the LED it appears that it reverses itself(on for no activity and off for activity). I tried messing with the LED connectors
on the motherboard and at the front panel but nothing works.
I used to have the AHCI version of the Samsung SM951 512GB M.2 SSD in the slot and the HDD activity LED functioned correctly.
Except for that the 750 works just fine.
For the record, my setup;
Asus X99 Deluxe with most current bios
32GB Crucial Sport Ballistix DIMMs
1TB Seagate HD
Intel 750 400GB 2.5" SSD with most current firmware
Nvidia GeForce Titan graphics card
Asus Hyper Kit NVMe adapter
Is this a problem that will be fixed with future firmware or should I just return it and hope the replacement doesn't do the same thing?

Ok, sounds good.
I went and ahead and did a replacement RMA with Newegg, if the new drive does it I will keep it and just wait for updates and hope it's something that can be fixed with firmware.
There are a few things you can check in order to make sure the SSD is configured properly.
Make sure you are using the proper BIOS settings in your system. You can check this with the Motherboard Manufacturer, and also, you can find some configuration examples in the following document:
http://www.intel.com/support/ssdc/hpssd/sb/CS-035481.htm Intel® High Performance Solid-State Drives — Booting an NVMe* PCI Express* Solid State Drive
Also, install the Intel® Solid-State Drive Data Center Family for PCIe Drivers, current version is 184.108.40.2062, it can be downloaded at the following location:
In this case, we recommend you to review the BIOS settings and make sure you are using the recommended driver as mentioned in the previous post.
Also, you might want to check with the http://www.intel.com/support/oems.htm Computer Manufacturer Support as well, to know if they have any additional recommendations for this behavior, or system updates to prevent it.
Well an update since my last post on this thread. New Intel 750 firmware and drivers have come out since then, I've upgraded both. The light seems to behaving more like normal. It's not constantly on anymore although it still seems reversed(LED on=no activity, LED off=activity). I believe this is some specific problem between my Asus X99 Deluxe motherboard and the Intel 750 SSD.
Definitively LED activity was reversed in one firmware or driver updates that Intel offered.
I've a DC P3700 HHHL driver almost from its launching and with the first firmware and drivers, the activity amber LED was off most of time, going to on only with some desktop activity.
After a firmware or driver update, this behaviour reversed, and now my drive amber LED is almost all time on, with only small blinks.
I dont know which update reversed the behaviour, because the activity LED on HHHL device is on back of computer case, and I noticed this only recently, after several firmware and drivers updates.
I suppose this applies to 750 SSD since the firmware and drivers are the same for both drives.
But the drive itself is OK and a very fast one.
My motherboard is an ASUS X99 Rampage V Extreme.
Engineering has confirmed that the current LED behavior for Intel® SSD 750 series is: LED is ON in idle mode and is OFF when drive is active. We would like to inform that the LED behavior for the 750 series will be modified/fixed in next FW update (which will be released later this year).
Thanks for confirming that behaviour, and having a DC P3700 drive, that (LED is ON in idle mode), I can confirm this also applies to DC P3XXX series, at least.
