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

2017-09-23, 17:01 PM

Hi Team.

So my thinkpad t450s just crashed in the midst of playing some music.

Then it rebooted and said 2101: Detection error on SSD1 (M.2)

I cant come back to my OS because it is installed on the said SSD.

Already read the manual and opened the thing up and cleaned and reseated the SSD. But does not help.

Guess the SSD is broken? OR does anyone have any other ideas??

Thanks a lot!

Has anyone found the fix for the SSD1, M.2 error on T450? I have an out of warranty ThinkPad and I've updated BIOS and Windows. Also just updated MS Office. Have also turned off hibernation and sleep modes. Stays "on" all the time now.

Lenovo T450s

On bootup I'm getting an ERROR 2101: Detection error on SSD M.2

ESC gets me past the error message and OS boots OK

I do not and have never had a SSD M2 card installed in my T450s

Nothing in Device manager

How do I resolve this error?

Thank you

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 4 days now.
