笔记本电脑的屏幕在拔下电源线时关闭

从W8最近升级到Windows 8.1 Pro之后，拔下电源线后，笔记本电脑的屏幕（华硕X54H）将关闭。

重新插入电源后，它可以重新打开。在屏幕关闭时，将处理键盘和鼠标输入。我的设置告诉屏幕在电池不活动2分钟后熄灭。我以前遇到过电池问题，以前我的笔记本电脑在用电池运行5分钟后应该会掉电（尽管还剩60％），但是我认为这无关紧要。

其他信息将根据要求提供。谁能帮我弄清楚发生了什么事？我怎样才能停止这种行为？

The screen turns off when the Display Brightness is set too low and some correct driver is not installed.

To fix this issue, go into Power Options, Edit Plan Settings of the active plan, set Change plan brightness to the maximum for both battery and plugged in. You can access the same setting under Change advanced power settings, Display, Display Brightness.

You can still control the brightness using the keyboard. The control panel setting seems decoupled from the keyboard setting (I am guessing it is a driver issue that is at the root of the problem).

I had the same problem (screen turning off when unplugging my laptop from the power). It started two days after I upgraded to Windows 8.1.

I resolved this by using the Power Options control panel. I noticed that this problem only occurred for me when using the "balanced" power profile. If I switched to either the "power saver" or "high performance" profile, the problem went away.

I fixed this for the "balanced" profile by selecting "change plan settings..." and clicking "restore default power settings for this plan." I can now use the "balanced" profile without the problem reoccurring. There must be some specific setting that is causing this behavior, but I'm not sure what it is.

Windows 8.1 might use up slightly more battery, but this probably is an issue with your battery. Try going into a BIOS setup screen or something separate from Windows, then try unplugging your power cord and see what happens.

If your screen shuts off your battery won't hold any charge at all. Otherwise, it might be detecting the battery is below the 5% automatic hibernate mark, which could be a sign of an inaccurate battery reading. Try this: Go to Control Panel > Power Options > Click "Change plan settings" next to your preferred power plan > Click "Change advanced power settings" > Scroll to bottom and hit "Battery" > Click "Critical battery action" > Change it to "Sleep."

When your computer hits the 5% mark, it should go to sleep instead of hibernation. When it shuts off the screen and goes to sleep completely, power it back on and observe the battery levels. See how long it lasts before it completely shuts off at 0%.

When your computer is going into hibernation the screen shuts off immediately but sometimes mouse and keyboard input is still accepted for about 15-30 seconds before it powers off completely.

Either way, you should try replacing your battery. It shouldn't have anything to do with your upgrade to 8.1. This should just be coincidental. It is possible, but in order to test it you would have to restore to 8.0.

Just a follow-up - I contacted ASUS customer service and informed them of my issue - during a online chat with their customer service representative I was told repeatedly that my model was not designed for Windows 8/8.1 and that ASUS does not recommend installing unsupported operating systems on their hardware. So in other words, don't expect any help from ASUS.

So I restored Windows 8 to the laptop from a disk image I made BEFORE I upgraded to Windows 8.1 and I'm up and running without the battery issue. I hoped that ASUS would be more supportive of their hardware, but since a laptop bought in 2011 can't get support in 2013, I will certainly consider this in making future hardware purchases or recommendations on their hardware...

For ASUS N61 I had the same problem upgrading to Windows 8.1 (black screen/blank screen upon login and after restart during installation)

A. To complete installation I attached different additional screen (that computer did not had saved settings), so I could see last steps of installation

B. 1. To use computer after installation - find power state using Fn+Space (hot keys) that displays screen on main laptop display (removing power cable also can change state

2. When you have working power plan that does not produce black screen. Go into power plan settings and delete all PowerGear type power plans (leave only default microsoft power plan settings - High, Normal, Batery saver modes)

3. Uninstall ATK asus hotkeys from programs to avoid accidentally switching to invalid power states

Apparently ASUS power modes are not compatible with Windows 8.1 causing blank screen on laptop (although they worked for me on Windows 8)

Go to Power Options > Select Power Saver mode > Processor power management (turn them all off). Problem solved.

This is potentially a problem with your power settings for your battery. Here are some instructions to check out your settings for on battery power use:

1. Right click your desktop and click on "Personalize"
2. On the bottom right of the Personalize window click the link to "Screen Saver"
3. In the Screen Saver Settings window click on "Change power settings"
4. The Power Options window will show up
5. On the left hand side click "Choose when to turn off the display"
6. Now the Edit Plan Settings window should appear
7. Click on "Change advanced power setting"
8. There are a few options in this Power Options window that you should check on which can all be seen under the Battery option. Reserve battery level would probably be my first guess for what needs to be changed. My battery level is set for 7% for reserve yours may be much higher. Your Laptop also might have its "Low battery level" set very high which would make a lot of these battery saving settings happen much faster. There are a lot of scenarios with different combinations of settings for the battery that might cause the shutdown in this window.
9. If playing around with these settings does not fix the issue I would recommend doing a battery test. Your Laptop manufacturer should have a battery test program on their site to see if your battery is faulty. There are sometimes even repairs with the firmware updates for batteries and your model may need the update for Windows 8.1
