My SSD uses software (drivers are software ) dating 2006 according to device manager, I never updated the firmware and as it looks now won't do it very soon even though there are some available, and device manager says it is up to date.
Device manager isn't the best way to check for driver updates, rarely it does update drivers.
The best way to update drivers is by downloading the drivers from Acer (in your case), double click (or single click, depending on your settings for opening a file) the executable and follow the on-screen instructions for installation.
It is pretty much the same as with other software you would install,
You open the executable
You follow the on-screen instructions and sometimes you need to be careful that you don't install something that comes with the installation but is unwanted. With driver installations you can usually quickly go through the installation as there is nothing else coming with the installation.
