How long is the warranty of Lichuan Education Bureau's all-in-one machine?

All-in-one machine enjoys a three-year limited warranty.

All-in-one office machines can be scrapped in about five years. Generally speaking, the life of computer LCD is 5-8 years, but it turns black after 5 years. The integrated machine is placed on the desktop for a long time, just like a monitor. As time goes by, the appearance will naturally become less and less beautiful. Therefore, the service life of all-in-one office machines is about 5 years, which explains why many large enterprises will replace office computers every 3-5 years.

Configuration life. One to two years, especially the motherboard and CPU. The average speed of hardware update is 1.5 years, which leads to system and software update. Therefore, some brands with good after-sales service will provide a certain period of warranty service for those CPUs and motherboards. For example, M24B 1 of onebot, this all-in-one machine enjoys a three-year limited warranty service, providing three-year free warranty service for main components such as CPU, motherboard, graphics card, memory, hard disk, power adapter and display screen, and one-year free warranty service for peripheral components.

The heat dissipation of an all-in-one office machine has been criticized because its heat dissipation space is as small as that of a notebook computer. So pay attention to ventilation when using it, and turn it off when not using it for a long time. However, in recent years, the heat dissipation design of all-in-one machines is good. For example, onebot's latest M24B 1 uses pure copper heat dissipation module. As we all know, the thermal conductivity of aluminum is 735KJ/(M.H.K), while that of copper is 1386KJ/(M.H.K). Other things being equal, copper is used.
