T450s Thinkpad - ERROR 2101: Detection error on SSD1 (M.2)

2015-08-03, 18:13 PM

Model: T450s

Equiped as:

Intel i5

4+4GB RAM

256GB SSD (M.2) Configured as boot disk running Win 7 x64

500GB HDD as additional storage

 

Issue:

Seemingly at random, approx once every one to two weeks while PC is on and at the desktop but not actively being used (meaning no user is sitting in front of it performing tasks) it will error and crash.  The error is a black screen with the following error:

 

2101: Detection error on SSD1 (M.2) 

Press Esc to continue.

 

According to the user Esc does nothing and the only escape is to long press the physical power button until a power down occurs.  On reboot the system comes up without issue.  No user has actually seen the crash take place. 

 

MY QUESTION(S):

1st.  Is this most likely an issue with the T450s not being able to reliably boot from the m.2 slot or is this more likely an issue with the SSD installed in the m.2 slot?

2nd.  Is this something altogether different?  Any (knowledgeable) advice or info appreciated.

It is hard to diagnose without seeing it, but my experience has been that the Gen4 and later CPUs (like yours) support a very low power state that is incompatible with some devices. (that would make it a problem with the card) Make sure you have the latest BIOS and power manager software installed. Look in the device manager and find the M.2 SSD. There should be a power management tab. Turn off the option to allow the system shut the device off to save energy.

Ah of course, great idea.  I didn't even think about that Haswell power saving feature.  Makes sense why it would only occur when not receiving direct input from a user.  I will try and report.  Thanks again.

Hey I'm having this same issue and in my m.2 drive's properties window, I don't have the power managment tab (as admin). Is there a way to access and disable it through the registry?

 

T450s

Windows 10 (Preloaded)

Intel(R) Core(TM) i7-5600U CPU @ 2.60Ghz

2GB(4/MB+8/DIMM) DDR3L_1600

500GB HDD 7200rpm

128GB M.2 SSD [MyDigital] *As my OS Boot Drive

 

[Additional Info]: BSOD happens at exactly 120 minutes of idle

Same issue on my T460s.  Lots of 2101 errors, especially coming out of hibernation, or after it sits idle for a while.  I updated BIOS, Lenovo drivers, removed the M.2 and cleaned the contacts, unchecked power management & disk sleep, wore garlic around my neck...everything I read.  I was getting that error, and some random BSOD's several times a day.

 

I was about to buy a new SSD M.2 and decided to take one more shot at cleaning.  This time I took a look with a loupe.  Look at this white corrosion bridging the contacts where the M.2 socket is soldered to the mobo.  Socket on the left is unused and there's a big difference.  I tried air - lots of it.  It didn't move it at all.  So its some corrosion, and its not on the contacts the M.2 touches.  I just sprayed contact cleaner on a toothbrush, and brushed it like your dentist tells you to brush.  It took several applications, but it now looks just like the un-used socket on the left.  I haven't had a 2101 for 3 days now.

Well, ^^that^^ was over a month ago. No 2101 errors, and no Unexpected_store_exception BSOD's. I felt like a genius.

 

They came back a couple weeks ago, now its several times per day. M.2 slot is still very clean. So now I saved an image and put it on a new SSD drive. This is a Samsung 256 with an NVMe interface (My T460s will go either SATA or NVMe...not true of all computers). If it's been a few months and I haven't posted back here, you might assume the new drive was the fix.
