Its disassembly method is very simple. Like ThinkPad T470, you only need to remove the external battery first, and remove all the screws on the bottom case, then use the guitar pick to slowly open the bottom case, and there are many snaps on the back cover to securing the case to the laptop body, be careful do not break the snaps.
With the bottom case removed, you can get access to the internal battery, M.2 SSD, RAM, CMOS battery, hard drive, Wi-Fi card, heat sink, cooling fan and motherboard.
Lenovo ThinkPad T480 has two available RAM slots each supporting up to 16GB of DDR4-2400 memory, that mean you can upgrade the RAM to 32GB. The unit we’ve tested comes with one 8GB DDR4-2400 RAM from Samsung.
Amazingly, it is equipped with a 2242 PCIe NVMe 128GB M.2 SSD from Toshiba with a number of KBG30ZMT128G, Lenovo P/N: 00UP650, SSSOL24702.
The laptop also comes with a 500GB mechanical hard disk, if necessary, you can replace it with a larger capacity hard disk.
Another version of T480 has a M.2 2280 SSD and installed via a adapter. Please see the ThinkPad T480 review here.
