2101: Detection error on SSD (M.2)

I get the following message when I turn on the laptop:


2101: Detection error on SSD (M.2)


The laptop (T560) is new and was only received on the 13 May 2016.  When it occurs I run the

diagnostics and can usually get the machine to boot up.


However, the error then reoccurs at a later stage, usually if the machine has been idle for a while. 


I have lodged a service call with Lenovo but thought I would share my experience here and see if anyone else has the same issue?

Re: 2101: Detection error on SSD (M.2)

Have you tried updating the BIOS ?

Had the same issue on T460s Laptops. 

Error occurred when laptop is put into hibernate mode and then borught out of hibernation.

Resolved it by updating the BIOS to the latest available one here on Lenovo Support.

Re: 2101: Detection error on SSD (M.2)

I have a client who is experiencing this issue on multiple T560's. Another symptom is that the hard drive is not being detected.  Since Windows is not booting, what is the best method for updating the BIOS?

I would update using a DVD drive connected via USB

Re: 2101: Detection error on SSD (M.2)

I too had the same error on my T550s while using the 16 GB caching SSD. I run Windows 7 Professional and have the latest BIOS. I called Lenovo Warranty support and they sent out a replacement SSD which resolved the issue but they neglected to provide any details how to activate the SSD as a caching drive.


It seems from reading through various threads that quite a few users are experiencing m.2 SSD drive issues. My drive is installed in the WWAN slot, if that makes a difference.


As an aside, I contacted Transcend and asked about premature drive failures installed in Lenovo Thinkpad m.2 slots. They confirmed that had received several reports of drive failures but that they appear to be sporatic and no specific cause has been determined.

Re: 2101: Detection error on SSD (M.2)

I have a new x270 images just a week ago. I have the same problem. While in idle for a while, it shuts off and won't boot - 2101 detection error on storage device. Unknowingly, I ran the diagnostics, it booted fine. Then the same error after staying in idle f okr few hours. Again. Unknowingly. I ran the diagnostics. It booted again fine. The error repeated again, while I was using it at a meeting and probably was not use for about 30 mins or so. I was not able to boot at all. It simply does not detect the ssd. This time, I disabled the CPU power management in bios and still did not boot. I ran the diagnostics again. It booted fine. I have a scheduled appointment wit the linovo tech support to replace the ssd. 


Wondering how did you solve your problem as I see it was reported almost a year ago.

Re: 2101: Detection error on SSD (M.2)



Not sure if you ever received a response to the 2101 Detection error on SSD M2. / windows freezing or crashing,


When you have examined the windows event viewer and there is no evidence of a software fault then consider the hardware.


I believe this symptom can be caused by moisture/contaminants between the SSD drive connections and its interface with the motherboard. I won’t go into the detail but here is what I have done a number of times to fix this problem with 100% success in different machines. My X1 Yoga has been the latest candidate of this process.




-First I would recommend doing a backup of data on the SSD.

-Purchasing a specialist electronics contact cleaner (WD 40 Specialist electronics contact cleaner £7).

-Purchase latex gloves (£2).

-Purchase specialist grade buds for electronics £2 (they look like cotton buds).




-Do this on a dry day and have access to an outside space

-Be clean about everything you do

-Put the gloves on. 

-Remove the SSD from the motherboard.

-Spray the contact cleaner directly on to the SSD’s contacts and use the buds to clean and remove any dirt/oxidation/moisture that you may not be able to see with the naked eye so clean well.

-Allow the contact cleaner to dry (5 mins max)

-Spray the screw that was used to hold the SSD in place and use the bud to remove dirt and allow to dry.

-Replace the SSD back into the motherboard and ensure the SSD is pushed all the way into the motherboard, be firm.

-Hold the SSD in place while using the screw to resecure the SSD and make sure the screw is tight (Don’t over do it)

-Wait for 5 mins before switching on the machine.
