Changing Ram Slots

admin

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.

As for repairing it, technically yes, it could be repaired, but you would need to find a new RAM slot and know how to solder the connections onto the board. Chances are you would be cannibalizing another board to get the part and if you had the skills required to repair it, you wouldn’t need to ask. Upgrading memory is easier later, when memory slots are available. Some PCs have a pairing requirement. The memory slots are organized in pairs, and every pair must have the same DIMM size. For example, you can have 3GB of memory in a PC with four memory banks. That’s two 1GB DIMMs in two slots and two 512MB DIMMs in the other two slots.

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.

Here’s the internal battery, 11.4V, 24Wh, Lenovo FRU: 01AV489.

Update
Another version of ThinkPad T480 has an M.2 2280 SSD and installed via an adapter. Please see the ThinkPad T480 review here.

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?

If the reported memory size isn't correct or if your Mac mini repeatedly plays three tones, it may be having trouble recognizing a memory module. If this happens, shut down your Mac mini, verify the module specifications against the requirements for your Mac mini model, and then repeat the memory installation instructions to make sure that the modules are installed correctly. If you still have issues, remove the memory and consult the support information that came with the memory, or contact the vendor who provided the memory.
