Problem (solved) with some machines

I have already installed MX100 3 512 and 2 M500 in different machines and I am very satisfied with these choices.
However, I was surprised by a problem with the MX100 last 512 mounted in a portable ACER.
It worked great until you spent battery by disconnecting the power to the laptop.
the computer crashed (freeze). I was about to return the equipment when I found the solution on a US forum. It seems that this phenomenon exists with other brands Acer ... and perhaps other SSD.
The solution is very simple, just turn off the disk cache (uncheck in the Crucial drive properties) ... and everything works fine then (The cache is not necessary a priori for an SSD).
