我在使用Windows 7时遇到了一些问题，但我仍然经常将它与我的MacBook Pro一起使用。最近出现的一个新问题与屏幕保护程序和电源选项有关。我将屏幕保护程序设置为在 10 分钟后启动，但没有任何反应！我还将我的电脑设置为在 1 小时后进入睡眠状态，并在 30 分钟后关闭显示器。由于某种原因，显示器会在 30 分钟后关闭，但计算机从未进入睡眠状态！
如果您的显示器无法关闭或您的计算机无法按照您设置的时间间隔进入睡眠状态，这可能是由许多不同的问题引起的。在本文中，我将尝试向您介绍我尝试过的所有不同方法，希望其中一种方法对您有用。
此外，请务必查看我的其他帖子， Windows 和Windows 7中的睡眠问题故障排除终极指南将不会睡眠以获取其他可能的修复。
方法 1 – 拔下鼠标/键盘
如果您有其中一款精美的USB或蓝牙(Bluetooth)或无线鼠标/键盘，请尝试拔下或断开它们，看看问题是否消失。很多(Lots)人都提到，一旦鼠标断开连接，问题就消失了。似乎有些鼠标即使在不使用时也会继续向计算机发送信号，因此会阻止计算机进入睡眠状态。显然，这不是理想的解决方案，因为不在桌面上使用鼠标会有点烦人。但首先，您至少可以弄清楚这是否是问题所在。如果是，请尝试方法2。
方法 2 – 更新驱动程序
如果您运行的是64 位Windows 7，那么您应该尝试为您的鼠标或键盘找到并下载正确的 64 位驱动程序。使用较旧的驱动程序可能会导致此问题，因此最好通过访问制造商的网站并下载它们来自行更新这些驱动程序。确保驱动程序适用于您的键盘/鼠标的特定型号。
方法 3 – 拔下所有 USB 设备
与方法 1 相关，您应该尝试断开所有USB设备并检查问题。这包括USB 记忆(USB)棒、外部硬盘驱动器或其他USB硬件。有些人注意到通过USB连接的(USB)MagicJack存在这个问题。
方法 4 – 禁用唤醒功能
另一种可能解决此问题的方法是防止硬件能够唤醒计算机。通常，您会希望您的鼠标/键盘执行此操作，因此无需更改它，但其他硬件可能会导致屏幕保护程序和电源选项永远无法激活。
为此，请单击开始(Start)并输入设备管理器(Device Manager)。打开设备管理器(Open Device Manager)，然后右键单击一个硬件，例如网卡，然后单击属性(Properties)。
接下来，单击“电源管理”选项卡并取消选中“(Power Management )允许此设备唤醒计算机(Allow this device to wake the computer)”框。
请注意，您不会在设备管理器(Device Manager)中的所有项目上都有此选项卡，只有可以实际唤醒计算机的项目。您可以尝试一次禁用一项，然后查看问题何时消失。可能是系统上的某些其他硬件导致计算机从不休眠或关闭显示器。
此外，您可以通过转到命令提示符并键入以下命令来确定最后关闭计算机的设备：
powercfg /lastwake
powercfg /devicequery wake_armed
方法 5 – 高级电源选项
默认情况下，您可以在Windows 7中选择一个电源计划并在那里设置您的电源设置。但是，您还可以设置高级电源选项，有时计划和高级设置不匹配。高级设置将覆盖电源计划，因此您可能在那里设置了一些东西，但由于高级电源选项中的设置，它不起作用。
单击(Click)开始并(Start)输入电源选项(Power Options)。这将打开电源选项对话框。单击(Click)活动电源计划旁边的更改计划设置。(Change plan settings)
最后，您可以在此处转到睡眠(Sleep)和显示(Display)，并确保此处的值与您的电源计划中的值相匹配。如果他们不这样做，那么改变他们，希望你的问题会消失。
方法 6 – 关闭和打开
如果没有其他方法，您可以尝试的最后一件事是关闭笔记本电脑或计算机，取出电池或拔下计算机，等待大约 5 分钟，然后尝试再次打开计算机。令人惊奇的是，这可以解决USB端口的某些问题，这些问题可能会导致计算机上的电源设置出现问题。但是您确实必须确保取出电池或拔下计算机，而不仅仅是关机。

Windows 7 Screensaver and Power Options Not Working?
І’ve had my share of problems with Windows 7, but I still use it regularly along with my MacBook Pro. One new problem that creеped up recently has to do with the screensaver and power options. І set my sсreensaver to stаrt after 10 minuteѕ, but nothing happened! I also set my PC to go to sleep after 1 hour and turn off the display after 30 minutes. For some reason, the display woυld turn оff after 30 minutes, but the computer never went to sleep!
If you’re having issues with your monitor not turning off or your computer not going to sleep at the time intervals you set, it could be caused by a number of different issues. In this article, I’ll try to walk you through all the different methods I tried and hopefully one of them will work for you.
Also, be sure to check out my other posts, the Ultimate Guide to Troubleshooting Sleep Issues in Windows and Windows 7 Will Not Sleep for other possible fixes.
Method 1 – Unplug Mouse/Keyboard
If you have one of those fancy USB or Bluetooth or wireless mice/keyboards, try unplugging or disconnecting them and seeing if the problem goes away. Lots of people have mentioned that once the mouse was disconnected, the problem simply disappeared. It seems that some of the mice keep sending signals to the computer even when it’s not being used and therefore prevent the computer from sleeping. Obviously, this is not the ideal solution as not using your mouse with a desktop would be kind of annoying. But to start, you can at least figure out if that’s the issue. If it is, then try method 2.
Method 2 – Update Drivers
If you are running Windows 7 64-bit, then you should try to find and download the correct 64-bit drivers for your mouse or keyboard. Using older drivers can cause this problem, so it’s a good idea to update these on your own by going to the manufacturer’s website and downloading them. Make sure the drivers are for the specific model of your keyboard/mouse.
Method 3 – Unplug All USB Devices
Related to method 1, you should try to disconnect all your USB devices and check for the problem. This includes things like USB sticks, external hard drives, or other USB hardware. Some people have noted having this problem with MagicJack, which connects via USB.
Method 4 – Disable Wake Features
Another way to possibly fix this problem is to prevent hardware from being able to wake up the computer. Normally, you would want your mouse/keyboard to do this, so there’s no need to change that, but other hardware may be causing the screensaver and power options to never activate.
To do this, click on Start and type in Device Manager. Open Device Manager and then right-click on a piece of hardware, such as the network card and click on Properties.
Next, click on the Power Management tab and uncheck the box that says Allow this device to wake the computer.
Note that you won’t have this tab on all items in Device Manager, only the ones that can actually wake up the computer. You can try disabling items one at a time and seeing when the problem goes away. It could be some other hardware on your system causing the computer to never sleep or turn off the display.
Also, you can figure out which device turned your computer off last by going to the command prompt and typing in these commands:
powercfg /lastwake
powercfg /devicequery wake_armed
Method 5 – Advanced Power Options
By default, you can choose a power plan in Windows 7 and set your power settings there. However, there are also advanced power options that you can set and sometimes the plan and the advanced settings don’t match. The advanced settings will override the power plan and therefore you might have something set there, but it won’t work because of what is set in advanced power options.
Click on Start and type in Power Options. This opens the power options dialog. Click on Change plan settings next to the active power plan.
Finally, here you can go to Sleep and Display and make sure the values here match those on your power plan. If they don’t, then change them and hopefully your problem will go away.
Method 6 – Turn Off and On
The last thing you can try if you are if nothing else works is to turn off the laptop or computer, remove the battery or unplug the computer, wait about 5 minute and then try turning the computer on again. It’s amazing how this can fix certain problems with the USB ports, which can cause problems with the power settings on the computer. But you really have to make sure you take out the battery or unplug the computer, not just shutdown.
If you’re still having this problem in Windows 7, post a comment here with your setup and any additional details and we’ll try to help. Enjoy!
