* **Get 16GB of RAM**: tihs is basically a given, make sure you have at least 16. 8 will bottleneck the CPU, and 32 is too much for ost tasks.
* If youre lucky and get a T480 with the 2280 SSD bracket, you will see a boost in disk speeds, but if you only do tasks such as office work/programming, a normal SATA SSD will have an identical performance. If you want, you can put an ***M.2 A+E key 2242 SSD*** into the WWAN slot for extra storage.
* ***AVOID TN PANELS LIKE THE PLAGUE***: If buying used and you are not planning to upgrade the panel, please avoid the TN panels, because they will make your T480 experience horrendous and near unbearable. I recommend the following panels if you upgrade it:
- * NV140FHM-N61: **no mounting brackets**, has enough clearance and is 100%sRGB, 30pin eDP, non-touch, IGZO low power, 400 nit and is 1920x1080. Supports 60 and 48hz and is quite bright
- * N140HCG-GQ2/GR2: **no mounting brackets**, has enough clearance, 100%sRGB, 30pin eDP, non-touch, IGZO, has pretty damn bad backlight bleed, is 400 nit but quite dim, and is 1920x1080.
- * B140HAN01.0/.1/.2/.3: has mounting brackets, has enough clearance, and is 45%NTSC, 30pin eDP, non-touch, not low power, 250~300 nits and is 1920x1080. Colors are quite washed out and is okay-bright. All "compatible" panels are acceptable, much better than a TN.
+ * NE140FHM-N62: **no mounting brackets**, has enough clearance and is 96%DCI-P3 (1.07 billion colors!), 30 pin eDP, non-touch, IGZO low power, 500 nit and is 1920x1080. It should have 60 and 48hz support. I have not tested it, but in theory this should be the best panel.

- you could go for more exotic options, like the NV140FHM-N62, or even 2/4k panels like the B140QAN02.0 (which I used, but swapped out, because it has clearance issues and creates 2 bulges on the bezel. Colors are amazing though). Any panel higher than 1080p requires a 40 pin cable; and swapping the cable out is quite painful as you have to disassemble the hinge.

- * **Make sure you have the internal battery!** the PowerBridge system is extremely useful, and even if you do not intend to hotswap batteries, the extra mileage you get is quite important at times. I have a 72wH (in reality, 68 due to it being aftermarket) external 6 cell and an internal 24wH 3 cell, which gives me 9 total cells around ~90wH. My T480 did not even come with an internal battery because Lenovo did not ship these batteries in colder countries due to _chemistry™ reasons_.

For daily tasks, the T480 smashes all of them, and most definitely can handle video editing, even with just the iGPU. Speaking of which, it gets over 80fps on 22 ren/22 sim chunks medium settings with sodium in a Minecraft Singleplayer world. It is portable, quite light, definitely 1-handable and is a great daily driver.
