Inside Lenovo Ideapad S540 (15) – disassembly and upgrade options

This is one of the great laptops in terms of price to performance and efficiency ratio. Let’s see how is it able to push for more than the expected performance of a ULV hardware.

1. Remove the bottom plate

First, if you want to get inside of this laptop, you need to remove 10 Torx-headed screws. Then, carefully pry the bottom panel up with a plastic tool and you should be able to meet the internals of this notebook.


2. Battery

Lenovo has equipped the Ideapad S540 (15) with a decent 52.5Wh battery pack, which can drag the device for 11 hours and a half of Web browsing and 12 hours of video playback. If you want to upgrade one of the components, you would want to unplug the battery first. However, if you want to swap batteries, you can remove this one by unscrewing the three designated screws.


3. Memory and storage

As you can see from the images below, there is only one RAM DIMM available for upgrades. This is because there are aleady 4GB soldered directly onto the motherboard. Additionally, you can put a PCIe x4 drive in the M.2 slot or a 2.5″ SATA drive on the left side of the battery.


4. Cooling system

Last but not least – the cooling. We are happy when we see more thought from manufacturers when designing their cooling solutions, rather than slapping a single heat pipe and a fan and calling it a day. Here, Lenovo uses two heat pipes, as one is shared between the CPU and the GPU and one is dedicated for the graphics card only. Moreover, there are some plates surrounding the dies, which help with cooling the VRAM chips and the VRM modules. Then, at the end, you can see two fans blowing out the heat of a very long heat spreader. You can see how the Ideapad S540 (15) fared in the Temperature tests section of our review.
