How to open Lenovo ThinkPad T14s Gen 4 – disassembly and upgrade options
Step 1: Accessing the Internal Components
- Ensure the Lenovo ThinkPad T14s Gen 4 is powered off and placed on a soft, clean surface to prevent scratches or damage.
- Remove the 5 captive Phillips-head screws from the bottom of the laptop.
- Begin prying the bottom panel off with a plastic tool, starting from one of the top two corners.
Hint: Be gentle during this process to avoid damaging the internal clips or the laptop casing.
Step 2: Removing the Battery
- Disconnect the battery by unplugging its connector from the motherboard.
- Remove the 4 Phillips-head screws securing the battery to the laptop’s chassis, then lift the 57Wh battery away from the device.
Caution: Handle the battery and its connector with care to avoid any damage.
More info: The 57Wh battery provides up to 11 hours and 7 minutes of web browsing or 8 hours and 20 minutes of video playback, showcasing efficient power usage.
Memory
The Lenovo ThinkPad T14s Gen 4 comes with soldered 16 or 32GB of LPDDR5x-4800MHz RAM. Unfortunately, it’s not upgradable but it is enough for multitasking and productivity tasks.
Storage Upgrade
