My current laptop has 4gb of ram installed from the factory. The specs on my current ram are:
Memory speed: 1600mhz
configuration features: 1 x 4gb
technology: DDR3L SDRAM
installed size: 4gb
max supported size: 8gb
form factor: SO-DIMM 204-pin
slots: 2
empty slots: 1

One of the old computers that I would like to rob the ram from specs are:

Max Supported Size 8 GB
Technology DDR3 SDRAM
Speed 1333 MHz
Slots Qty 2
Empty Slots 0
Memory Speed 1333 MHz
Configuration Features 1 x 4 GB + 1 x 2 GB
Technology DDR3 SDRAM
Installed Size 6 GB

The other computer I could get ram from has the following specs:

MEMORY
Max Supported Size 4 GB
Technology DDR2 SDRAM
Slots Qty 2
Empty Slots 0
RAM
Configuration Features 2 x 1 GB
Technology DDR2 SDRAM
Installed Size 2 GB

Would either of these work in my new laptop. Also, one of the laptops has a has this processor:

CPU Intel Core i5 (3rd Gen) 3210M / 2.5 GHz
Max Turbo Speed 3.1 GHz
Number of Cores Dual-Core
Cache 3 MB
64-bit Computing Yes
Features Intel Turbo Boost Technology 2.0

My current laptop has this processor:
CPU Intel Core i3 (5th Gen) 5015U / 2.1 GHz
Number of Cores Dual-Core
Cache 3 MB
64-bit Computing Yes

Would it be a good idea to replace the newer i3 with the older i5?

Thanks for reading and your advice.

DDR2 <> DDR3 <> DDR3L RAM. Assuming you could even get the DDR3 RAM to fit into the DDR3L slots in your laptop, it wouldn't work because it wouldn't be getting enough voltage.

CPUs won't work, either. the i5-3210M is a Socket G2 CPU, while your current one uses Socket BGA 1168...assuming you could even remove the CPU, as they're generally soldered to the board. Best bet would be to check the manufacturer's support site & see if the CPU can be removed...but again, even assuming that it's not soldered to the mainboard, taking apart & putting a laptop back together is extremely difficult & time-consuming, as all of the pieces are so tightly fit that just about any slight misstep is going to pretty much ruin it.

The processors won't drop in no matter what you do simply because of the vast difference in the platform/socket/architecture. Pertaining to the ram, it's bad practice to mix and match two(or more) different sticks of ram to get a cumulative amount. If you must upgrade your ram, you must do so with a kit or a pair of identical rams.

One other thing to note is that DDR3/DDR3L are also vastly different than DDR2 ram.

FYI, specs mean little if you passed on the SKU for your current laptop.

Contrary to that line, you can drop in DDR3L ram into a DDR3 slot so it will fit, the point is that DDR3L where L stands for low voltage means that it operates at 1.35v as opposed to DDR3 which operates at 1.5~1.65v.

Last time I checked Intel made sure that you can drop in a 4th gen processor into a 3rd gen socket let alone a 5th gen processor into a 3rd gen socket.

Except that his current laptop is using the DDR3L, & he wanted to add regular DDR3 from an older system.

And, no, they've never made it so that the 4th- or later generation chips could fit into the same sockets. His current laptop's Broadwell chip uses a Ball Grid Array ("BGA 1168"), which means it has balls of solder along the bottom of the chip. The i5 he wanted to use is the older Pin Grid Array ("Socket G2/rPGA 988B"), where the chip has pins on the bottom (like AMD chips do). Those aren't compatible technologies. All of the Ivy Bridge mobile i5 CPUs were either built for Socket G2 or Socket BGA 1023 systems, so they won't work. If he wants an i5, he's limited to a Haswell-ULT (i5-4200Y/4202Y/4210Y/4220Y/4300Y/4302Y), Haswell-ULX (i5-4200U/4210U/4250U/4260U/4300U/4310U/4350U/4360U), or a Broadwell-U (i5-5200U/5250U/5300U/5350U) chip...& again, that's only if a) it's not soldered to the board, & b) the motherboard will support the chip.
