Hello,
My name is Thiago and I'm Brazilian, I own a Lenovo ThinkPad T480 (20L6S5TQ00) since 2018, that I've already made some modifications to and I'd like to share my experience here:
First upgrade was to add more RAM memory, it originally came with 8GB (1x slot only) and I increased it to 16GB (8GB + 8GB) putting the same brand and specifications (2400MHz DDR4) as the existing one. With twice the amount of RAM, I confess that using it, was smoother in certain office activities, I noticed a good difference when I made this modification.
Second upgrade, was to put a SSD M.2 2242 256GB PCIe nvme in place of FIBOCOM L830-EB. After some time using the T480, I noticed that I rarely used 4G mobile internet, there is wifi practically everywhere. Out of curiosity I researched and found a crazy person who had done what I was very tempted to do, replace the 4G with an SSD and put it as primary to run the operating system (Win 11 Pro). Of course, I did a very deep research on which models of ssd M.2 2242 are reliable, which would not overheat due to the large capacity (512GB, 1TB, for example), arriving at the verdict that the 256gb brought me the best cost benefit, and safity.
Third upgrade, was to eliminate HDD/Sata 256GB for a monstrous SSD SAMSUNG 870 QVO with 4TB capacity. Before making this modification, I had spent a few months with the configuration of the ssd m.2 2242 with the operating system and the HDD/SATA as a secondary. But I confess that the agility and fluidity of the operating system running on the ssd m.2 2242, was not so free, because of the HDD/Sata tying up some processes, mainly when I was going to load files that were on the HDD/Sata. Faced with this situation, I purchased a 4TB SAMSUNG 860 QVO SSD and replaced the HDD/Sata. WOW, the T480 literally turned into a rocket, I turn it on in seconds, I put all the big files on the secondary and practically leave the primary with just Win 11 Pro, and when I have the possibility, I install the programs on the secondary, so as not to compromise the 256GB of the SSD M.2 2242.
My recent experience was playing Forza Horizon 3 through the Microsoft Store using the XBOX App, and amazingly, the NVIDIA® GeForce® MX150 with 2 GB GDDR5, in terms of the game itself, was not meant to run at high graphics settings, however, for some reason, I don't know if on the part of the T480 or the Win 11 Pro, when opening the game and putting everything in the extreme, at the maximum, at the highest of the highest of the highest, the game works! Of course I'm not going to have a fluid game with 60FPS, it runs but depending on the part of the scenario it stays there between its 28FPS falling sometimes to 19FPS, KkkkkkkkKKkkkk... Anyway, I selected the lowest resolution that it accepts to stay in full screen (without black borders on the sides), 48hz and in the high quality option (with possibility two more options until you reach the extreme), and for me, it ran satisfactorily to be able to play well.
I searched the internet for something related about the video card using part of the RAM memory or the SSD, as being VRAM, and I tend to believe that in this specific case of the FH3, this is happening. I say this because in the Task Manager screen, in the GPU part 1 (NVIDIA GeForce MX150), dedicated GPU memory = 0.0/2.0GB / GPU memory = 0.0/9.9GB / GPU memory shared = 0.0/7.9GB , that is, I don't have the technical knowledge to explain why, but I'm super satisfied with my T480!
My T480 has the following settings:
i7-8650U CPU @ 1.90GHz 2.11GHz
RAM 16.0GB (15.8 GB usable)
Windows 11 Pro (22H2)
Primary SSD M.2 2242 256 GB (with Windows)
Secondary SSD 2.5" SAMSUNG 870 QVO 4TB
