I upgraded my Aspire S5-391 to Win 8.1. I originally had Win 7, then upgraded to Win 8.0 no problem. Now, having upgraded to Win 8.1 I am getting an error message (blue screen). Searching online, I found a post that said some solid state drives had trouble with Win 8, and I should get an updated firmware. Acer does not seem to have posted one under the downloads section. With the Intel tool, I was able to find that the drive was a LITEON SSD (a mini mSATA). I found the drive mentioned, but they did not have drivers (they mainly sell OEM). Can Acer post a firmware upgrade for this?
