You have 2GB old stick and 4GB new stick from transcend.  Do you have the transcent part number?  Could you type in the information shown on the stickers of each stick, or just post a picture of each stick. 

Example:

BRAND NEW RAM

OLD RAM SAMSUNG

The OLD/Samsung is pc3, 1.5v.

The NEW/Hynix is pc3L, 1.35V.

http://www.memory4less.com/hynix-4gb-sodimm-pc12800-hmt351s6efr8a-pb?rid=99&utm_source=bing&utm_medi...

If 1.5V works, the new stick needs to be 1.5V.

Crucial shows 1.35v for your system.

Based on that, your Hynix should work and your Samsung should not work.

If you use one stick of memory, it goes in the bottom slot (slot 0).

Reference HMM, page 46.

P.S. crucial might be showing the wrong voltage for your machine????

Page 102, item 15 of your HMM lists five 2GB memories and five 4GB memories.

Your Samsung 2GB stick is listed:

11200340 Lenovo Sodimm 2G M471b5773dh0-ck0 Ddr3 1600Mhz (samsung)

 Of the five 2GB all are 1.5v except:

11200396 Lenovo Sodimm2g Sm321nh08iaf Ddr3l 1600Mhz1.35v (micron stick).

Again, the HMM is for several machines.

If your machine came with Samsung 1.5 volt, any new memory should be 1.5 volt.

Your Hynix PC3L stick is not usable in your machine. Crucial needs to review their specs for your machine.  It could be different models of the G580 uses different memory voltages, ie 1.5 vs 1.35.
