 Hello, this is LaptopMedia, and today, we will show you how to open the second generation Lenovo ThinkPad T15G and what's inside of it. Upgrading this laptop is pretty easy. First, on the bottom panel, you will find a service lid. Undo its single Philips head captive screw, and pry it with a plastic tool. This will reveal two Sodom ports for memory expansion, and two M.2 slots for storage. To continue, you need to undo a couple more screws, which will set the keyboard loose. Then, turn the device around, open the lid, and slide the entire keyboard upwards. After that, pull it away together with the secondary touchpad buttons. Be careful, as there are two ribbon cables that you need to unplug. Then, you will see a metal cover, held in place by three Philips head screws. Undo them, and slide the cover upwards to remove it. Ultimately, this leads to the rest of the upgrade options. Here, you have two more Sodom slots, that combined with the two on the other side, support up to 128GB of DDR4 RAM. Also, you can see a third M.2 slot for storage. If you want to continue with the teardown, and take a look at the cooling, you need to remove the entire bottom panel. After you undo all of the visible screws, remove the SIM card tray, using an ejection tool. Then, pry the bottom panel with a plastic tool and lift it away from the device.

The battery inside has a capacity of 94W hours. It lasts for 10 hours and 30 minutes of web browsing, or nearly 8 hours of video playback. To remove it, unplug the connector from the motherboard, and unscrew all three Philips head screws. As far as the cooling goes, there is one huge heat pipe cooling the CPU, while another one is shared between the processor and the GPU. The graphics card also gets two more heat pipes. As you can see, there are four heat sinks, and two fans, as well as a couple of heat spreaders, meant for the graphics memory and the VRMs. If you'd like to see more disassembly videos of the latest notebooks we would highly appreciate if you hit the like button and subscribe to the channel.
