People who know computers come in to see the detailed description?

1. Because I have come into contact with many Lenovo notebooks at work, especially thinkpad x250 series. There is something wrong with the structure of this notebook. The hard disk and memory in the motherboard are not fixed well, which is very easy to lead to blue screen.

2. Then there are the ThinkPad computers newly bought by two colleagues, which often have problems. One can't be charged, and the other can't be turned on or off.

3. Lenovo can be so big and has its advantages behind it, but it is said that Lenovo's R&D investment is not high.

Personally, I think Dell's computer is better than Lenovo's, and Dell's desktop chassis structure is particularly creative.
