Inside Lenovo ThinkPad L15 – disassembly and upgrade options
Quite honestly, this laptop is not too far from being an ordinary business notebook. However, it supports up to 64GB of DDR4 memory in dual channel, which is still something rarely seen on the market.

1. Remove the bottom plate
In order to make changes on the inside of this device, you have to undo 9 Phillips-head screws. They stay attached to the bottom panel even after you unscrew them, which means it would be difficult to lose them. Before starting the prying process, make sure you remove the SIM card tray.
2. Battery
Unfortunately, the 45Wh battery pack in this notebook is glued to the chassis, in addition to being secured by three Phillips-head screws. We don’t really see a point of Lenovo doing so, other than preventing customers change their batteries, should the die after the warranty period ends.
3. Memory and storage
In terms of upgradability, we see two RAM SODIMM slots, which support up to 64GB of DDR4 memory in dual-channel mode. Additionally, our model comes with a single M.2 PCIe x4 slot.
4. Cooling system
Looking at the cooling solution, we see a long and reasonably thick heat pipe. By the way, our model features only a processor with no dedicated GPU, however, you can clearly see the mounting spot, where it would sit, should you order your laptop equipped with the Radeon 625.

can we change the processor if we want later?
Of course not, that option has pretty much disappeared around 7 years ago, mainly thanks to Intel.
Why does my laptop have no connection to this slot?
It’s so frustrating that you can’t add a 2.5″ SSD. There’s even room for it, but it’s blocked off!
