Inside Lenovo ThinkPad T15g Gen 2 – disassembly and upgrade options

Accessing all of Lenovo ThinkPad T15g Gen 2’s upgrade options is an adventure. However, it is well worth it.

1. Service lid

Upgrading this laptop is pretty easy. First, on the bottom panel, you will find a service lid. Undo its single Phillips-head captive screw, and pry it with a plastic tool. This will reveal two SODIMM ports for memory expansion, and two M.2 slots for storage.


2. Take out the keyboard

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 Phillips-head screws. Undo them, and slide the cover upwards to remove it.


3. Remove the bottom panel

Ultimately, this leads to the rest of the upgrade options. Here, you have two more SODIMM 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.


4. Battery

The battery inside has a capacity of 94Wh. 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 Phillips-head screws.


5. Cooling system

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.

Lenovo ThinkPad T15g Gen 2 in-depth review

Ah, we love it when business computers offer more than simply business computing capabilities. The ThinkPad T15g Gen 2 is one such device that shares a lot more with gaming computers than with its "regular" ThinkPad cousins. However, it should not be considered as a laptop made to play games, but more of one that could help you create games. To ensure you would have no trouble doing so, Lenovo paired its machine with some Tiger Lake CPUs, and even their Xeon iterations. Respectively, the latter options support ECC memory, which would be very helpful in every developer's work. Okay, but wha[...]
