Lenovo ThinkPad 25 Repairのヘルプ: 自分で修理する方法を学ぶ

ThinkPad is a line of business-oriented laptop computers and tablets originally sold by IBM and then by Lenovo. ThinkPad computers had a distinct black, boxy design that was inspired by a Japanese bento lunchbox. The first ThinkPads were released in October 1992. For many years, ThinkPad laptops were the only laptops certified for use on the International Space Station.

Lenovo released the 25th-anniversary Retro ThinkPad 25 in October 2017. The ThinkPad 25 model is based on the T470 but includes the seven-Row “Classic” keyboard with the layout found on the ThinkPad —20 Series. The ThinkPad logo also received a splash of color that is reminiscent of the IBM-era ThinkPad laptops. In 2011, the last ThinkPad models with the seven-row keyboards were released.

Like the ThinkPad T470, the ThinkPad 25 uses 6th- and 7th-generation Intel processors with options for a Core i3, Core i5, or Core i7 CPU. The devices use Intel’s integrated graphics or an optional Nvidia GeForce 940MX graphics card for heavier workloads. Behind the back cover, the laptop has two slots for up to 32 GB of memory. The machine can be equipped with a 2.5-inch drive or an M.2 SSD, both of which are replaceable. The wireless card is also accessible along with the optional WWAN cellular card. To complement this, the machine has an optional micro-SIM slot inside the bottom battery compartment.
