 Hello, this is Nick from Laptop Media and today we will show you how to open the Intel version of the Lenovo ThinkPad L15 Gen 4. To access the laptop's internals, you have to undo 10 Philips head screws. This screw is captive, so it'll slightly lift the panel up so you can easily start popping the bottom plate. You also need to eject the SIM card tray before prying the bottom plate with a plastic tool. Please remember, it would be of great help to us if you just hit the like button and subscribe to our channel. That would motivate us to make even more and better videos for you. The battery here is the optional 57 watt hour model. The base version is a 46.5 watt hour unit. And the top variant has a capacity of 63 watt hours. To take out the battery, pull out the connector from the main board and then undo the four Philips head screws that keep the unit fixed to the chassis. The optional unit has enough juice for 8 hours and 20 minutes of web browsing, or 6 hours and 15 minutes of video playback. For future memory upgrades, there are two Sodims for up to 64GB of DDR4, 3200 MHz RAM. Next to the two Sodims is positioned the W1 slot for optional 4G connectivity. Storage wise, there is just one M.2 slot for 2242 Gen4 SSDs. The pre-installed NVMe is protected by a metal plate that has a thin thermal pad on the inside. Another pad is placed on the motherboard right below the SSD. The cooling isn't massive, but it looks sufficient for a laptop with an IGPU, one fan, a pair of heat pipes, one heat sink, and a heat spreader.
