Vostro 420 powers off when Start->Sleep selected in Win 7 Pro
I've been having problems with unexpected power off when coming out of sleep since Oct 2013. This particular problem began after the start of the year. I've updated the BIOS to the latest, v1.3.0, & installed 3 video patches (3 others were not appropriate for my configuration).
Since there are many other patches recommended would anyone have a suggestion which group to try next?
