01/08/2025 Update: Unfortunately after a few hours of using the laptop on battery, it only lasts for 10 minutes before shutting off. I would understand if it came with OEM batteries, but it was third party. Shipping a laptop with a old third party battery that barely holds a charge is not OK, and now I have to spend more money on replacements.My ThinkPad T480 laptop arrived very quickly and looked brand-new cosmetically, with the screen and keyboard completely free of dust. It came preloaded with Windows 10, but I opted to install Linux instead for a faster and more secure experience. I noticed two differences compared to the listing:- The listing mentioned an i5-8250U processor, but I received the slightly faster (by about 5%) i5-8350U instead. The 8350U also supports virtualization, which could be useful if needed.- The listing also mentioned a fingerprint reader, but my unit did not include one. However, this wasn’t an issue for me since I prefer password logins over biometrics.The T480 also includes Thunderbolt 3, but it’s worth noting a critical firmware bug discovered a couple of years ago. This bug could cause the controller chip to fail over time, resulting in issues such as the inability to charge the laptop, effectively bricking it since it relies on USB Type-C charging. When I powered on the laptop for the first time, I checked the Thunderbolt firmware version on Windows, which showed version 14. The bug was fixed in version 20 and higher, so I recommend updating the firmware as soon as possible to avoid potential problems. I recommend following guides and using Ubuntu (via bootable USB)Overall, despite the slightly differing specs and outdated firmware, this is a really good laptop with plenty of upgradability
