How to open Lenovo ThinkBook 15 Gen 4 – disassembly and upgrade options

To pop this laptop open, you need to undo a total of 10 Phillips-head screws. Then, pry the bottom panel, starting from the front. It is best to use a plastic tool.

2. Remove the battery

Our configuration features the smaller 45Wh battery pack. It lasts for 7 hours of Web browsing, or 5 hours of video playback. To remove it, unplug it from the motherboard, and undo all three Phillips-head screws that keep it attached to the chassis.

3. Upgrade memory and storage

This machine comes with 8GB of DDR4 RAM soldered to the motherboard. You can further expand it by up to 32GB via the single SODIMM slot. Storage-wise, there are two M.2 PCIe x4 slots, both of which support Gen 4 SSDs.
