I have a fresh installed laptop, DE is lxde. It is a clean system, no more tweak.

Recently I found a strange problem: after I close the lid about 5 minutes, laptop will shutdown itself!

I donot remeber I have do some setting about power management, and I have installed pm-utils, but not acpid.

Is it a default feature of archlinux on laptop?

Hi Zhao.

"Is it a default feature of archlinux on laptop?" No it's not, for sure.

My laptop will automatically shut down when it overheats (it's a good way of telling me that I just blocked the air vent), so I'm guessing that's what you're seeing. Don't test it too much if you're on a Macbook, I hear they can melt when overheating with a closed lid! - Bryan

Do you have installed any of power management tools like cpupower/cpufreq, pm-utils, acpid and laptop-mode tools? If not please check your BIOS settings for anything related deep energy saving settings. I neve use LXDE before so I don't know anything of that DE but you might want to check for any built-in energy management system it could have.
