Ideapad Y40 and Y40-80 memory upgrade

This 8 GB DDR3L SODIMM is built for the Lenovo Ideapad Y40 and Y40-80 series. It runs at 1600 MHz with CL11 timing and a low 1.35 V operating voltage. The single 204-pin module installs directly into the notebook memory slot.

System-specific compatibility guaranteed

The module is validated for Lenovo part numbers 5941xxx and 5942xxx. Buyers with a different laptop model or a system that requires a different memory generation cannot use this module. Non-ECC unbuffered operation suits standard consumer notebooks.

What is the correct way to seat this 204-pin DDR3L stick so it locks in properly?
