问HN：有哪些Linux工具可以用来诊断系统频繁挂起的问题？
我有一台运行Ubuntu的笔记本电脑。在运行一段时间后（有时是5-10分钟，有时更长），系统会卡死，无法响应键盘或鼠标输入。在我打开系统或将其送到可以检查硬件问题的技术人员那里之前，我想知道是否有方法可以使用Linux工具来诊断系统。
这个问题是否可能是由于分区中的坏块引起的？这个问题是在我对硬盘使用fdisk之后开始的？有没有办法确认这一点？

I have a laptop which runs Ubuntu. After running for a while (sometimes 5-10 mins, sometimes more), the system hangs and stops responding to keyboard or mouse inputs.
Before I open the system up or take them to a technician who can look at the hardware issues, I was wondering if there are ways I can diagnose the system using linux tools.
Can the issue happen due to bad blocks in the partition? The issue started after I used fdisk on the hard drive? Are there ways to confirm this?
