This isn't a motherboard that I bought... it's a laptop.
Sure, the various motherboards I've bought myself over the years for the several home-built machines I've constructed came with a very detailed manual. And in particular, the documentation regarding memory is typically quite extensive. but motherboard documentation is a different kettle of fish, intended for a system builder and it needs to provide very explicit details about lots of things. In contrast, a laptop user guide is generally intended for a different category of user.
I agree with you insofar as motherboard documentation. But we're not discussing a motherboard here.
You're talking about a motherboard here. This isn't how a laptop interior looks.If the manual tell you nothing does the motherboard have 2 colored ram slots.
If so most likely two of the same color will be the proper slots to use for two sticks of ram.
Just try two of the same color and see what happens. It won't hurt anything.
If those two colored slots don't work try the other color.
If that don't work just fill all slots. That has got to work if all the ram module and motherboard slots are working properly.
Yes, that's the hardware maintenance manual for the P70. But you're misinterpreting what you've pointed to. There are two RAM "bays", not two RAM "slots". And each "bay" has two "slots", thus producing a total of four memory "slots".What I find here you only have two ram slotsand two m.2 slots.

Am I looking at the same computer?
Page 74 describes one of the two memory bays, in particular this is the one on the underside of the machine accessed simply by removing the bottom cover. This bay has TWO SLOTS... which I've empirically discovered to be #2 and #4.
Page 78 describes the second of the two memory bays, in particular this is the one under the keyboard which must be removed (with three screws) in order to access it. This bay also has TWO SLOTS... which I've empirically discovered to be #1 and #3.
So, two memory bays, each of which has two SODIMM sockets. Total of four memory sockets available.
The M.2 bay is completely separate, and is described starting on page 72. This bay has two PCIe sockets, supporting either one or two PCIe M.2 SSD/NVMe devices (configured either individually or as RAID). This thread is not concerned with the M.2 bay.
Anyway, once I get the second Crucial memory card I will do the requisite "corrective surgery" as I've previously described. Once I've got these identical matching two cards in "paired sockets" #1 and #3 (under the keyboard) I'm sure I will get "dual".
