日本How to open Lenovo ThinkPad L15 Gen 4 (Intel) – disassembly and upgrade options
Opening the Laptop
- Undo the 10 Phillips-head screws securing the bottom panel of the laptop.
- Eject the SIM card tray using a SIM eject tool or a small pin.
- Use a plastic pry tool to gently separate the bottom panel from the chassis. Start from one corner and work your way around carefully.
Caution: Be gentle to avoid damaging the clips that hold the bottom panel in place.
Removing the Battery
- Disconnect the battery connector from the mainboard by gently pulling it out with a plastic tool.
- Undo the four Phillips-head screws that secure the battery to the chassis.
- Lift the battery out of its compartment.
More info: The laptop comes with three battery options: a base model with a 46.5Wh unit, an optional 57Wh model, and a top model with a 63Wh capacity. The 57Wh variant offers up to 8 hours and 20 minutes of web browsing or 6 hours and 15 minutes of video playback.
Upgrading the RAM
- Locate the two SODIMM slots next to the WWAN slot on the motherboard.
- Remove any existing RAM by gently pulling the clips on each side of the RAM stick outward. The RAM will pop up and can be pulled out.
- Insert the new DDR4-3200 MHz RAM modules into the slots at an angle, then push down until the clips lock them in place.

Maintenance of the Cooling System
- Locate the cooling system components – one fan, a pair of heat pipes, one heat sink, and a heat spreader.
- Remove the screws securing the fan and heat sink to the motherboard.
- Clean the fan and heat sink with compressed air. If replacing the thermal paste, clean the old paste off the CPU and the heat sink, then apply a new thin layer.
- Reattach the fan and heat sink, ensuring that the screws are tightened securely.
Caution: Ensure the thermal paste is applied thinly and evenly to prevent overheating.
More info: Although not massive, the cooling system is deemed sufficient for a laptop equipped with an integrated GPU (iGPU), ensuring stable performance under normal usage.
