I'm trying to find out if the application is running on a laptop or on a desktop, any ideas on how to achieve this?
我想知道应用程序是在笔记本电脑上运行还是在桌面上运行，有什么想法可以实现吗?
Note: I'm interested only in API's written in Delphi and/or C++.
注意:我只对用Delphi和/或c++编写的API感兴趣。
EDIT: my target platform is Windows XP+, even Windows 7 only is OK.
编辑:我的目标平台是Windows XP+，即使只有Windows 7也可以。
LAST EDIT: thank you all for your help, I have created a unit with helper methods(In Delphi) feel free to translate to C++ or other languages and/or help extending(or fixing possible flaws). The unit can be found here http://www.delphigeist.com/2011/02/laptop-specific-functions.html
最后一次编辑:感谢您的帮助，我创建了一个带有helper方法的单元(在Delphi中)，您可以将其转换为c++或其他语言，或者帮助扩展(或修复可能的缺陷)。单位可以在这里找到http://www.delphigeist.com/2011/02/laptop-specific-functions.html

Use this struct : SYSTEM_POWER_STATUS, and check the value of ACLineStatus field.
使用这个struct: SYSTEM_POWER_STATUS，并检查ACLineStatus字段的值。
- ACLineStatus = 0 => The system is not using AC power > Laptop + battery
- ACLineStatus = 0 =>系统没有使用交流电源>笔记本电脑+电池
- ACLineStatus = 1 => The system is using AC power => Laptop + AC
- ACLineStatus = 1 =>系统使用交流电源=>笔记本+ AC
- ACLineStatus = 255 => AC power status is unknown => Desktop
- ACLineStatus = 255 =>交流电源状态未知=>桌面。
Disclaimer : Try experimenting with these. I'm not claiming if they're reliable. But they're almost correct.
免责声明:试试这些。我不是在说他们是否可靠。但是他们几乎是正确的。

Use GetSystemPowerStatus to get the value of the above mentioned structure.
使用getsyst力气获取上述结构的值。
By the way, you can also experiment with the other fields of the structure; maybe you can find some useful pattern, giving you some combination of values of different fields to help you reliably detect if application is running on laptop or not.
顺便说一下，你也可以对结构的其他领域进行实验;也许您可以找到一些有用的模式，提供一些不同字段值的组合，以帮助您可靠地检测应用程序是否在笔记本上运行。

I don't think there's a standard way to check whether the application runs on a laptop, but I think there's also no standard rationale for needing to know this.
我不认为有一种标准的方法来检查应用程序是否在笔记本上运行，但我认为也没有标准的理由需要知道这一点。
The point is also that a laptop is no so much different from a desktop: there are laptops that get never moved, and I guess it would be possible to build a desktop with an embedded UPS (seen as a battery?)
问题的关键在于，笔记本电脑和桌面电脑并没有太大的不同:有些笔记本电脑永远不会被移动，我猜有可能用嵌入式UPS(被视为电池?)
I think you should find out if it's a laptop using the features you need to check in a laptop:
我认为你应该弄清楚这是否是一台笔记本电脑，使用你需要在笔记本电脑上检查的功能:
-
Do you want to know if it's a laptop because your application needs to behave differently if the computer may be moved around? Then check if it has got a battery plugged in.
你想知道它是否是笔记本电脑吗?因为如果你的应用程序需要移动电脑，那么它的行为就会有所不同。然后检查它是否插上了电池。
-
Do you want to know if it's a laptop in order to see whether hardware can be modified? In this case check the motherboard model or ask with a dialog box.
你想知道它是笔记本电脑还是硬件可以修改?在这种情况下，检查主板模型或询问对话框。
-
Do you need to check it in order to know if it will burn to death if used too intensively for too long? Just monitor the temperature...
你是否需要检查它，以知道它是否会烧到死亡，如果使用太久?监控温度……

Apparently, the hidden problem is that the company laptops typically have not enough memory, but the company desktops do. To address this specific problem, compare memory used against memory installed: EnumProcesses() and GetProcessMemoryInfo tells you the first; GetPhysicallyInstalledSystemMemory() tells you the second.
显然，隐藏的问题是，公司的笔记本电脑通常没有足够的内存，但公司的台式机却有。要解决这个特定的问题，请将使用的内存与安装的内存进行比较:EnumProcesses()和GetProcessMemoryInfo告诉您第一个问题;GetPhysicallyInstalledSystemMemory()告诉您第二个。
If they're too close, you can inform the user that there are 73 running processes using 2.5 GB, but only 2GB RAM is present. This is a valid reason for your program not to start.
如果它们太接近了，您可以通知用户有73个运行进程使用2.5 GB，但是只有2GB RAM存在。这是程序不启动的一个有效理由。

You could also check other things like:
你也可以检查其他东西，比如:
- Is battery connected
- 电池连接
- Is track pad connected
- 跟踪板连接
- Is PC Card installed Is
- 电脑卡是否已安装
- Has a certain type of CPU (low power, Atom, etc)
- 具有一定类型的CPU(低功耗、原子等)
- Has a screen unique to laptop.
- 拥有笔记本电脑特有的屏幕。
- laptop hardrive is 3.5"
- 笔记本电脑hardrive是3.5”
If a certain number of the above is true then you can assume laptop.
如果上面的某些数字是正确的，那么您可以假设是笔记本电脑。
You could also just ask the user at installation....
