The average life of a notebook is about 3-5 years (this is suitable for software updating). The general computer/kloc-0 is updated once every two years, the software is updated once a year, and the antivirus software is updated every day. If the computer is used for too long, many software can't use the new version, and the computer must adapt to the hardware.

If it takes a long time for the notebook to break down, it can be used for about 10 years (just without big software and new software), and it can also be used to process some documents, play old games and watch network TV.

1. If you want to adapt to the use of new software, you usually need to change it every 3-4 years.

2. If it can't be used all the time, then 8 years, 10 years will be fine.
