    Hi,
    Insert the memory, go to BIOS and move to Main tab, press F9 button, then press F10 button to save and exit, leave the laptop switched on for 10-15Mins and try to start again, it may take few minutes for the system to recognise the new RAM.

    What make you think both RAM chips are the same type?

    From the pictures, the 4GB stick has DDR3L marking. The 8GB has DD3, I believe it stands for DDR3.

    DDR3L and DDR3 sticks use different voltage.

    I think you may want to return the 8 GB stick and change for another 8GB stick with DDR3L 12800 spec.
