Internal layout Overview

By the looks of the internals, the only easy-to-access components are the M.2 drive and the HDD. The memory SO-DIMM DDR4 slots are kept under a metal casing with a plastic tape over it. The Y700 had a better internal layout as the RAMs were hidden under a metal foil which protects having any possible contact with the casing.

Cooling System

The cooling system dual fan system which sucks the air in from the underside and pushes through the bare copper heatpipe and heatsink array. The galvanised portion draws the from the base covering the i7 7700HQ and the GTX 1050 Ti. This is a typical design for a gaming notebook, but what always matters is the effectiveness of the fans while having a least possible amount of noise.


The primary drive storing the operating system is the 128GB Samsung MZVLW128 M.2 drive and the 1TB 7mm Seagate ST1000LM035-1RK172 2.5-inch mechanical HDD.


The memory packaging the on the Lenovo Y700 was sealed with a metal tape, making it easier to access. This needs a little care as there’s a thick plastic adhesive stuck over the metal enclosure, hiding away the 2x DDR4 slots. As per Intel HM175 chipset, the SO-DIMM DDR4 slots support.

Edit 08.06.2017: Lenovo provided a statement regarding the metal enclosure:

Due to increased component density on PCB, RAM slots are concealed under a metal cover to minimize RF noise that can potentially interfere with operability of system memory. The cover can be easily removed by wiggling and lifting it up from the PCB.


For wireless access via WiFi and Bluetooth, the Lenovo Y520 uses Intel Dual-Band AC 8265 chip which is an M.2 2230 chip working on both 2.4 GHz and 5 GHz band with 802.11 AC support, MIMO support and Bluetooth 4.2 enabled.
