How to open Lenovo ThinkPad P14s Gen 4 – disassembly and upgrade options

Ensure the Lenovo ThinkPad P14s Gen 4 is powered off and placed on a soft, clean surface to prevent scratches or damage.
Unscrew the seven captive Phillips-head screws from the bottom of the laptop.
Use a plastic tool to gently pry the bottom panel off, starting from one of the top two corners.

Hint: Be careful during this process to avoid damaging the internal clips or the laptop casing.

Step 2: Removing the Battery

Wear gloves to safely handle the built-in battery connector and avoid any potential short-circuiting.
Undo the 6 Phillips-head screws holding the battery in place, then carefully remove the optional 52.5Wh battery from the laptop.

Caution: Handle the battery and its connector with care to avoid any damage.

More info: The optional 52.5Wh battery provides up to 9 hours and 5 minutes of web browsing or 6 hours and 40 minutes of video playback, offering a solid battery life for productivity.

Memory Configuration

Depending on the model, the Lenovo ThinkPad P14s Gen 4 comes with either soldered-only memory up to 64GB of LPDDR5x-7500MHz (operating at 4800MHz due to platform limitations), or a combination of 16GB soldered memory and a SODIMM slot that supports an additional DDR5-5600MHz stick (operating at 5200MHz), for a total of up to 48GB.

Storage Upgrade

Identify the M.2 slot compatible with Gen 4 SSDs for storage upgrades. Consider installing a new NVMe SSD to enhance the laptop’s storage capacity and performance.
The NVMe SSD benefits from additional cooling provided by a metal shroud with a thermal pad on the inside, as well as another thermal pad placed on the mainboard beneath the SSD.
Choose and purchase a new drive when needed. Don’t forget to check out our Top M.2 SSDs Performance Rankings.

Examining the Cooling System

Inspect the cooling system, which includes two heat pipes shared between the CPU and the GPU, one heatsink, a single fan, and a couple of heat spreaders, designed to efficiently manage the thermal output of the device.
