Detection Error 2100 - M500 SSD in Lenovo X240 laptop

Question

I have a new Lenovo X240 out of the box.  I immediately upgraded with a Crucial M500 SSD 240mb drive.  The computer is running a fresh install of Windows 7 64-bit. The BIOS on the laptop is the most current.  The firmware on the M500 is the most current.  It seems that every several times I start or reboot the system I receive "DETECTION ERROR 2100".  After powering off the machine and powering it on again the computer will boot to Winddows. I have seen numerous posts about this issue between Crucial vs. Lenovo.  I've tried every suggested fix to no avail.  I have tried the configuration using an identical, brand new M500 SSD with the same results.  Am I missing something?
Thanks in advance for your suggestions,.

Hello mrtree and welcome to the Crucial forum. I spotted your post yesterday and spent some time Googling for info from the Lenovo support forum last night. I found several things you are probably aware of. First, this Detection Error 2100 is not limited to just the X240 series laptops, there are quite a few other models affected in the same way. Second, it is not limited to only Crucial SSDs, there are people with Samsungs, Toshibas, Intels, and even conventional drives that have experienced this same problem at system boot. These two observations indicate to me that problem is probably related to BIOS/firmware/driver issues. Since you have stated that you already installed the latest BIOS(v. 2.23?) and firmware(chipset v. 9.5.22.1760?), that leaves one area: drivers. From what I can see, the latest Intel RST drivers available are version 12.8.10.1005, dated 1/26/2014. Please be aware that there are seperate downloads for 32 and 64 bit systems. There is also a Solid State Drive Firmware Update Utility listed, but I do not recommend using it since Crucial M500s are not listed in the "Read Me" notes. Which brings up the question of SSD firmware, do you have the MU03 or MU05 firmware installed on your Crucial SSDs? Also, just to double check, do you have AHCI mode enabled in your BIOS settings? You'd be surprised at how many people overlook this. I suppose that Lenovo will get around to releasing updated software addressing this issue, as they have for the other brands of SSD drives, it's just a question of when. Edit: Two more things I thought of after my initail post. First, did you order your M500 directly from Crucial? When I ordered the M500 for my Lenovo T400 Thinkpad, I went to the website and used the advisor to find the M500 part number for my machine. I called to order several days later, and when I gave the part number to the customer representative, she immediately replied "that's for a Lenovo T400, correct?". That tells me there is a part number that is specific to the T400 series, and this may also be the case with the X240 series. Ordering from an online retailer or purchasing the M500 from a store may not have given you the correct part. Second, does your machine have Intel's Management Engine firmware installed, and do you have it enabled? Try entering BIOS and disabling it, just to see if this problem persists. I've noticed that on my T400, when I boot from the DVD drive or a USB stick, I see a brief warning message from the Management Engine stating that I'm not using the normal boot device, but then my machine boots regardless. Perhaps it's causing some sort of grief for your machine.
