Step 1: Accessing the Internal Components

  1. Ensure the Lenovo IdeaPad Slim 3 (15, Gen 8) is powered off and placed on a soft, clean surface to prevent scratches or damage.
  2. Remove the 10 Phillips-head screws from the bottom of the laptop.
  3. Use a plastic tool to gently pry the bottom panel off, starting from the back.

Hint: Be careful when prying to avoid damaging the internal clips or the laptop casing.


Step 2: Removing the Battery

  1. Disconnect the battery by unplugging its connector from the motherboard.
  2. Remove the 2 Phillips-head screws securing the battery to the laptop’s chassis, then lift the 47Wh battery away from the device.

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

More info: The 47Wh battery provides up to 11 hours and 7 minutes of web browsing, or 8 hours and 20 minutes of video playback, offering good battery life for daily activities.


Memory

  1. The device comes with 8GB, 12GB, or 16GB of soldered DDR4-3200MHz memory. The configuration determines whether the memory operates in single-channel or dual-channel mode.

More info: While memory is not upgradable due to its soldered nature, the available configurations should meet the needs of most users for multitasking and productivity tasks.

Storage Upgrade

  1. Identify the single M.2 slot on the motherboard that supports 2242 Gen 4 SSDs. Note that due to AMD platform limitations, the slot operates at Gen 3 speeds.
  2. Consider upgrading or adding an NVMe SSD to enhance the laptop’s storage capacity or improve overall system responsiveness and load times.

More info: A thermal pad beneath the preinstalled NVMe helps manage heat, ensuring sustained performance.
