Lenovo ThinkPad T480 Disassembly (SSD, RAM, HDD Upgrade Options)


In this guide, I will disassemble a Lenovo ThinkPad T480 laptop. I will remove the bottom case to upgrade the RAM, SSD, and HDD for my T480.

For the freshest produce, find us on Facebook for the latest teardown news.

Its disassembly method is very simple, just like the ThinkPad T470, you only need to remove the external battery first, and then remove all the screws on the bottom case. Use the guitar pick open the bottom case slowly, and there are many snaps on the back cover to securing the case to the laptop body. Be careful do not to 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, which means 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 part 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.

  1. Two things:

    1. you should disguise at least your serial number (S/N: PF-xxxxx at two places 1. at where also the CE logo is 2. at the sticker between RAM 1 and RAM 2) in the inside under-the-hood view photo, so it is no more public visible. 🙂

    2. here my inside under-the-hood view photo of my T480 i5 MX150 campus model with pre-installed WWAN antennas, for the comparison: https://www.reddit.com/r/thinkpad/comments/83838h/inside_the_german_t480_i5_mx150_campus_model/

    At my T480 the Samsung PM981 512 GB SSD with the part number MZVLB512HAJQ in the 2282 M.2 format is located inside the 2.5″ slot with a proprietary M.2 NVMe adapter.

  2. I’m falling back to options for the T480 because of this year’s disaster of a design T490.

    On Lenovo web site, I see T480 with two separate drive slots
    1. traditional 2.5″ slot for magnetic hard disk or M.2 2280 SSD.
    2. M.2 2242 SSD.

    How would I know, if I first buy it with a traditional disk, then replace it later with a M.2 2280 drive, that the adapter cable will be there? Or do I have to source for that cable component separately?
