Main features of Notebook Hardware Control
G o o g l e l i n k s
In the status section you can see the actual status of the notebooks hardware.
You can also start, stop and adjust the NHC monitoring function in the status section.
The NHC status section will show you the actual:
- cpu clock, cpu load, cpu speed and cpu voltage
- battery charge rate and life time
- cpu, case and hard disk temperature
- graphic card's core and memory clock or system memory information
- System power-on time
The NHC monitoring function allows you to draw the current hardware status. You can select to draw transparent or with background; on the desktop or on top.
You can also save the data on the hard disk.
You can enable to monitor the cpu clock, cpu load, cpu voltage, battery charge, battery charge rate, cpu temperature and hard disk temperature.
CPU Speed Control (CPU policy)
This section allows you to change the speed of your processor and change the Windows Power Scheme. This following cpu speed settings are supported:
Keeps the CPU at maximum speed.
(i.e. a Intel Pentium Dothan 1600MHz runs at 1600MHz continuously)
Keeps the CPU at the minimum speed.
(i.e. a Intel Pentium Dothan 1600MHz runs at 600MHz continuously)
Keeps the CPU at the minimum speed and allows further throttling depending on remaining battery power.
Switches between the minimum and maximum speed according to current CPU utilization.
(i.e. a Intel Pentium Dothan 1600MHz switches automatically between 600MHz and 1600MHz)
Custom dynamic switching allows you to change easily the default dynamic switching behavior of your CPU.
The possibility of changing the minimum and maximum multiplier and changing the minimum and maximum CPU load vales gives you
full control over the CPU dynamic switching steps. Custom dynamic switching also doesn't have short Voltage drops like on default
dynamic switching if CPU Voltage Control is enabled.
To show the custom dynamic switching steps click on the
icons in the cpu speed section.
With CPU Voltage Control you can change the default CPU Voltages to reduce heat dissipation, power consumption and prolong the battery lifetime.
When you set new Voltage, Notebook Hardware Control will make a short CPU stability check to test, if the CPU is stable on this Voltage.
If the CPU Voltage is to low, the System can stop responding and you have to restart the Computer.
If the CPU is stable in the short CPU stability check there is not guarantee that the CPU is stable over a
longer period of time. to be safe it is recommended to use the full
NHC CPU stability check
or programs like
Hot CPU Tester Pro
With the ACPI Control System you can visualize and control and hardware components like LCD brightness, WLAN,
notebook temperature or fan of the notebook.
The ACPI Control System use open source classes and so it can be adapted easily from each user to to every notebook with ACPI.
If the ACPI Thermal Zone is available on your notebook, NHC will show you all available temperature information
like CPU temperature. To avoid overheating you can set the CPU temperature on which the notebook should reduce the CPU clock or
shut down the computer.
ACPI control system details
The ACPI Control System option window will show you the actual configuration of the ACPI Control System.
The ACPI Control System is controlled by open source classes with the programming language c#.
For each manufacturer and notebook model it is possible to define a new class and adapt it to the notebook hardware easily.
More information on how program the ACPI Control System you will find in the section:
Programming the ACPI Control System
If you have some programming skills it is not difficult to write an ACPI Control System class for your system.
If you have created a working class for your system please publish this new class in the
Every user with the same system as yours can then use this new class and will be happy :-).
I will also add the source file in the next NHC release.
For example on the Samsung P40 Notebook it is possible to control with the ACPI Control System
and the open source class "SP40S" a lot of hardware components like:
- Change the LCD Brightness level (Graphic section)
- Switch on and off the wireless LAN
- Control the FAN speed and the turn on/off temperatures
ACPI Thermal Zone information
Advanced Battery settings
In the Advanced Battery settings section you can customize the appearance of the battery icons in the taskbar and system tray.
The option Hide the 'Default System Battery Icon' on battery operation
will remove the normal windows battery icon.
The option Use alternative function to detect the actual 'System Power Status'
is a workaround.
Use this option if you have problems with the keyboard or touchpad when using NHC.
For example when you type, the keyboard misses some keystrokes.
Example of the battery icons in the taskbar and system tray:
LCD Brightness Control
NHC allows you to set different LCD Panel Brightness levels on AC Line operation and Battery operation.
On Battery operation you can define tree different brightness levels.
The first brightness level from 0 to 33%, the second brightness level from 34 to 66% and the third brightness level from 67 to 100%
Hard Drive SMART Information
NHC utilizes S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) technology to monitor your hard drive's internal
S.M.A.R.T. attributes and drive temperatures, to predict possible drive fail and prevent data loss.
NHC lets you know about a potential disk health problem before you lose valuable data.
The Power-On Time Count will display you how much time your hard drive was already switched on.
If the reported time is wrong or not possible you can correct the time with the Correction value
and Power-On Time reference
With the NHC profile editor you can add, move, rename and remove NHC profiles in a easy way.
You can set different icons for each profile to differentiate the profiles easily.
If you create a new profile, NHC will copy the settings of the active NHC profile to the new profile.
You can open the NHC profile editor by clicking on the edit button in the NHC settings section.
The profile editor is only available on the Professional Edition.
