Vengeance RAM is performance RAM. It will not work in your laptop, due to aggressive timings. The diagnostic light pattern of 2 amber and 5 white signifies "Invalid memory installed", so that confirms the incompatibility. Here is RAM that Crucial guarantees compatible with your laptop. Whenever touching components or working inside a computer, wear a grounded wrist strap, also called anti-static wrist strap, ESD wrist strap, or ground bracelet. It's a cheap and sensible precaution. Rest the laptop on an anti-static mat or at least a reasonable alternative such as corrugated cardboard. (Repeatedly touching a metal case part is not sufficient mitigation with modern components.)
    Hi there!  I own an Inspiron 16 7620 2-in-1 Tried an upgrade from Corsair with Vengeance Sodimm DDR4 32 GB (dual 16), 3200 MHZ. Originally were fit 8 gb @ 3200 from Kingstone. As per specifications, my system shall support 32 GB dual, but not. Tried to disconnect the battery, no results. On another laptop (toshiba), these memories are working well. There is any clue on?  Observed that after 15 seconds, battery led is blinking 5 times white and 2 times red then a short pause, this is consecutively.  Thanks for any suggestion!
