Power saving and the kernel on a Dell Vostro 200

The power saving features on the Dell I've been using for a while have been bothering me for a while.  Its running Mint 17.1 cinnamon and has always had a few issues with sleep.  I tried all sorts of permutations but left on its own the machine always crashed after a while: when going into power saving mode.

I've not totally sorted it: but I have found a parameter to add to the kernel startup which helps quite a bit:

quiet splash acpi_backlight=vendor

You'll probably find using grub customizer the easiest way to test this parameter.
