I like Ubuntu, but it has been a problem for me for a long time: the hard disk temperature at the palm in the lower right corner is much higher than that of XP.

The reason is that there are many claims on the Internet, some of which are due to fingerprint recognition and wireless network interfaces. However, after the test, the possibility of Hard Disk connection is higher.

Ubuntu in AC mode, the hard disk is in high performance, the head is not in place, the hard disk does not slow down, so the temperature is higher than in XP. however, when a battery is used, in order to reduce the speed and save power on the hard disk, the head will return to the normal position, and the temperature will naturally fall down, but the head's return value will be as high as that in Windows 7 and Windows XP systems, it has a certain impact on the hard drive life (a tradeoff ).

If you want to reduce the hard disk temperature, you can use this solution:

1. Install laptop-mode-Tools

 sudo apt-get install laptop-mode-tools

2. Modify Power Management Configuration: laptop-mode.conf

 sudo gedit /etc/laptop-mode/laptop-mode.conf

Modify the configuration file:

 # For parameter descriptions, refer to the notes in the file.
Enable_laptop_mode_on_ac = 1 # enable laptop-mode when the notebook uses AC power.
Enable_laptop_mode_when_assist_closed = 1

Minimum_battery_charge_percent = 11
Disable_laptop_mode_on_critical_battery_level = 7

Control_hd_idle_timeout = 0
# Archlinux/Debian: The default value is 20. As a result, the hard disk is often stopped and switched. The default value of Ubuntu is 60. It took a few days to get started. In short, I disabled this feature.
Lm_ac_hd_idle_timeout_seconds = 20
Lm_batt_hd_idle_timeout_seconds = 20

Control_hd_powermgmt = 1
# Archlinux/Debian is disabled by default, and Ubuntu is enabled by default. I also set it to enable, but modify the following three values.
Bat _ hd_powermgmt = 192
Lm_act _ hd_powermgmt = 192
Nolm_ac_hd_powermgmt = 192

After the test (on ThinkPad), the hard disk temperature remains below 40 degrees after modification.
