    I am looking for a T14 amd gen2 or a L14 amd gen2, and I would love to see the article

    I saw some nasty things about the L14 on Linux, and seems that a bios update solved at least the majority of issues.. like laptop doesn't wake up from suspend, some keyboard keys, press themself, or not respond the keyboard and such..

    Here is the major thread: https://bbs.archlinux.org/viewtopic.php?id=269449
    For that price, I would buy one for sure..

    Is there any problems with the site , because previous articles [Featured], doesn't show in my browser recently, I don't know why :/

The reason they were popular is because they were also repairable as well as reasonably well supported with legacy ports (mainly RS-232) for interfacing with enterprise and hobby hardware. Lenovo is has been trashing the Thinkpad brand with these low end consumer grade hardware tricks wrapped in a formerly proud business lineup. Wouldn't touch the newer Thinkpads with a 10 foot pole.
      L14 maybe the answer to you, however the LCD display/speaker quality may not be as good as T14; also there are some issue reported with linux previously.

        I bet it's black friday price.

          Wasn't on Black Friday but a few days after, but don't recall exactly how they advertised it as what sort of Christmas special. Apparently it was even $1200~1250 on Black Friday itself.

            $1,187.40 for 20XF0030US (5650U, 8 GB RAM, 256 GB SSD)
            $1,493.40 for 20XF004UUS (5850U, 16 GB RAM, 512 GB SSD)
            Maybe that was Black Friday or something.

              Meh, not really: it's just a blit, same as any other, and even on an igpu the cost is basically zero. You can (and do) burn a ton of SHADER ops trying to make the low-res source "look better", via noisy resamplers etc, but the blit ITSELF is pretty much free.

              Back on topic: I like the power usage on this a LOT. If you're compiling code all day, having to worry about power in the late afternoon is a pain in the ass.

                You wish! The GPU literally has to fill 4 times as many pixels (in the case of 4K on FHD), apply textures and shaders 4 times as often, and this costs a lot of performance. Do compare it! Try running a game at the display's native resolution, then at super-resolution, and watch the frame rate drop. It is a neat feature, but it is certainly not free of cost by any means. Only in your dreams.

                  Hey, thanks for the link. It actually does offer a real 4K display with a native 4K resolution (for a higher price). Nice to know it is not just another fake 4K offer.

                  Still, this brings me back to my initial concern about the benefits of a 14" 4K display. The 4K display option does however also come with HDR400. So there is that.

                    No mention of battery drain during sleep/suspend? my T14 looses 10% overnight in both s3/sI0x sleep modes

                    Don't listen to anyone recommending an L14, 250nit brightness in 2021 is a joke

                      5.5 W is not really good, on Windows these laptops reach idle times of 14h and more and work times around 8-10 hours.

                      I am still happy so far (have a P14s with 5850U and a HP ProBook x360 435 G8) but the power consumption on Linux is really bad compared to Windows. It has gotten better with kernel 5.15 and now 5.16 but it is still very far away from the numbers that are possible on Windows.
