我不知道按了什么键，电脑一下子黑了，求高手帮忙
我女儿在电脑上乱按，不知道她按了什么键，屏幕一下子黑了，按什么键都亮不起来，因为我是笔记本电脑，要等里面的电源用完了才能重新启动，这要等到什么时候，求高手帮帮忙啊，到底按什么键能让电脑重新亮起了，画面出来
我按关机键没用啊
我有更好的答案
你看看你上边的f1到f12上边肯定有像显示屏的图案，按住Fn再按那个对应的 屏幕就能亮，要等里面的电源用完了才能重新启动，这个没必要，按住开机键几秒钟也会关机，或者把电源和电池都拔掉也可以关机，又不明白的可以HI我

把电池拔了不可以了吗？傻啊~~在不行就打电话，向你笔记本的售后问问啊！！！谢谢，希望能帮上你的忙~
你可以按到了休眠键，就是 SLEEP键，睡眠键，你再按一下开机键，不要动，过几秒就好，还有你说你的笔记本电源用完了才能重启是不可能的，你想重启很简单的，你只要按住开关机键7或8秒左右就会关机，你再按一下就又开机了，或是你把电池拿出来再装回去就好了
直接按开机键就可以了，再不行的话就重新启动
可能按到了待机键，建议像开机那样按下电源键，过一会屏幕就亮了

1.可以重启进入安全模式，在安全模式下尝试是否失灵。如果不失灵，可能是系统等软件问题，可以重新安装系统，并下载安装官网驱动。2.如果安全模式下还是失灵，可能是键盘故障，可以携带机器整机，购机发票和保修卡到服务中心做一下检测。若不清楚当地的服务中心地址和联系方式，可以通过下面网址查询距离最近的华硕服务中心：

笔记本电脑的键盘接近硬盘和CPU，这2个硬件都会发热，所以，键盘出故障是常有的事情，建议去维修店修理。当然你的电脑知识很过硬的话，可以自己拆开，将相应位置清理1下灰尘或者擦拭1下金属块。注意，笔记本比台式复杂，不要轻易自己动手哦

应该是按键坏了吧
排线松了。。。。
那请问怎么解决啊
先确定键下面有没有脏东西卡主，不行就把前面板拆下来排线重插一下，笔记本键盘没那么娇气，不可能一下子坏了2个
下面坏掉了，建议换一个新的键盘
坏了呗！！！！！！！
坏了，换一个

转载请注明出处：
要想做好android系统开发和源码定制的工作，用户输入系统是不得不去研究的部分。为什么呢？
1.&&&&&了解用户输入系统是android深度定制中定制所有与按键相关的事件响应和广播消息的第一步，真正了解了用户输入系统的整个流程，要改写相关的源码就会得心应手，不需要到处去找源码，到处去发帖子，焦头烂额了。
举个简单的例子，前两天看到有个朋友在论坛上发帖子，想要屏蔽掉android的音量键，不知如何下手。这时候如果你了解android用户输入系统，知道android的音量键定义的按键码是keyevent.keycode_volume_up、keyevent.keycode_volume_up，直接去搜索这两个keycode的响应函数，改之即可！有或者你知道这两个keycode与底层驱动之间的映射文件是qwerty.kl，而这个文件里面定义的这两个keycode的值在驱动文件中对应的是android的音量键，那么你也可以改掉这个映射文件，让其映射到其他的按键上，另音量键失效！又或者。。。。了解了用户输入系统，方案就随你自己选了。。。
2.&&&&&了解用户输入系统是android系统开发必不可少的步骤。真正了解了用户输入系统，你想定制android快捷键，在任何地方都能一键进入你的应用程序，或者定义一个功能快捷键？没问题！你想改写原有的快捷键？更加没问题！
举个简单的例子，前两天看到有朋友在论坛上发帖子，想说能在任何地方一键进入自己的应用程序，不知道该怎么办。这时候如果你了解android用户输入系统，知道按键定义从底层到上层的流程，知道android的消息机制Broadcast
Receiver，那么，随便在键盘上找一个键，把它加到android输入系统中，然后在适当的地方加个广播发送，在你的APP中加个广播接收，搞定！想要哪个键就哪个键！
行了，废话就这么多吧，下面开始进入正题。android用户输入系统分几篇介绍一下（目前只有第一篇，后面几篇会陆续补出来的）：

======================================================
按键,触摸屏流程分析
按键触摸屏流程分析:
WindowManagerService类的构造函数
WindowManagerService()
mQueue = new KeyQ();
因为 WindowManagerService.java
(frameworks/base/services/java/com/android/server)中有：&&&
private class KeyQ extends KeyInputQueue
KeyQ 是抽象类 KeyInputQueue 的实现，所以 new KeyQ类的时候实际上在 KeyInputQueue
类中创建了
一个线程 InputDeviceReader 专门用来冲设备读取按键事件，代码：
Thread mThread = new Thread("InputDeviceReader") {
public void run()
在循环中调用：readEvent(ev);
&&& send =
preprocessEvent(di, ev);
实际调用的是 KeyQ 类的 preprocessEvent 函数
&&& int keycode
= rotateKeyCodeLocked(ev.keycode);
int[] map = mKeyRotationM
for (int i=0; i&N; i+=2)
if (map[i] == keyCode)
return map[i+1];
addLocked(di, curTime,
ev.flags,RawInputEvent.CLASS_KEYBOARD,newKeyEvent(di, di.mDownTime,
curTime, down,keycode, 0, scancode,...));
QueuedEvent ev = obtainLocked(device, when, flags, classType,
readEvent() 实际上调用的是 com_android_server_KeyInputQueue.cpp
(frameworks/base/services/jni)中的：
static jboolean android_server_KeyInputQueue_readEvent(JNIEnv* env,
jobject clazz,jobject event)
bool res = hub-&getEvent(&deviceId,
&type, &scancode,
&keycode,&flags,
&value, &when);
调用的是 EventHub.cpp (frameworks/base/libs/ui)中的：
bool EventHub::getEvent(int32_t* outDeviceId, int32_t*
int32_t* outScancode, int32_t* outKeycode, uint32_t
*outFlags,
int32_t* outValue, nsecs_t* outWhen)
在函数中调用了读设备操作：res = read(mFDs[i].fd, &iev,
sizeof(iev));
在构造函数 WindowManagerService()调用 new KeyQ() 以后接着调用了：
mInputThread = new
InputDispatcherThread();&&&&&&
mInputThread.start();
来启动一个线程 InputDispatcherThread
process();
&&& QueuedEvent
ev = mQueue.getEvent(...)
因为WindowManagerService类中： final KeyQ mQ
所以实际上 InputDispatcherThread 线程实际上从 KeyQ 的事件队列中读取按键事件。
switch (ev.classType)
case RawInputEvent.CLASS_KEYBOARD:
dispatchKey((KeyEvent)ev.event, 0, 0);
mQueue.recycleEvent(ev);
case RawInputEvent.CLASS_TOUCHSCREEN:
&&& //Log.i(TAG,
"Read next event " + ev);
dispatchPointer(ev, (MotionEvent)ev.event, 0, 0);
===============================================================
KeyInputQueue.java
(frameworks/base/services/java/com/android/server):
的线程 Thread mThread = new Thread("InputDeviceReader") 本地调用：
readEvent(ev);读取按键。readEvent 调用的是文件：
com_android_server_KeyInputQueue.cpp
(frameworks/base/services/jni)中的函数：
static jboolean android_server_KeyInputQueue_readEvent(JNIEnv* env,
jobject clazz,
&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&
jobject event)
android_server_KeyInputQueue_readEvent中有：
hub = new EventH
bool res = hub-&getEvent(&deviceId,
&type, &scancode,
&&&&&&&&&&&
&flags, &value,
hub-&getEvent 调用的是
EventHub.cpp (frameworks/base/libs/ui) 文件中的函数：
bool EventHub::getEvent(int32_t* outDeviceId, int32_t*
int32_t* outScancode, int32_t* outKeycode, uint32_t
*outFlags,
int32_t* outValue, nsecs_t* outWhen)
读取按键。
class RefBase::weakref_impl : public RefBase::weakref_type
在系统启动后，android 会通过
static const char *device_path = "/dev/input";
bool EventHub::openPlatformInput(void)
res = scan_dir(device_path);
通过下面的函数打开设备。
int EventHub::open_device(const char *deviceName)
fd = open(deviceName, O_RDWR);
mFDs[mFDCount].fd =
mFDs[mFDCount].events = POLLIN;
ioctl(mFDs[mFDCount].fd, EVIOCGNAME(sizeof(devname)-1),
const char* root = getenv("ANDROID_ROOT");
snprintf(keylayoutFilename, sizeof(keylayoutFilename),
&&&&&&&&&&&&&&&&
"%s/usr/keylayout/%s.kl", root, tmpfn);
device-&layoutMap-&load(keylayoutFilename);
打开设备的时候，如果
device-&classes&CLASS_KEYBOARD 不等于 0
表明是键盘。
常用输入设备的定义有：
CLASS_KEYBOARD&&&&&
= 0x, //键盘
CLASS_ALPHAKEY&&&&&
CLASS_TOUCHSCREEN&& = 0x,
CLASS_TRACKBALL&&&&
= 0x //轨迹球
打开键盘设备的时候通过上面的 ioctl 获得设备名称，命令字 EVIOCGNAME 的定义在文件：
kernel/include/linux/input.h 中。
#define EVIOCGNAME(len)&&
_IOC(_IOC_READ, 'E', 0x06, len)
在内核键盘驱动文件 drivers/input/keyboard/pxa27x_keypad.c
中定义了设备名称：pxa27x-keypad
static struct platform_driver pxa27x_keypad_driver = {
.probe&&&&&&&
= pxa27x_keypad_probe,
.remove&&&&&&&
= __devexit_p(pxa27x_keypad_remove),
.suspend&&& =
pxa27x_keypad_suspend,
.resume&&&&&&&
= pxa27x_keypad_resume,
.driver&&&&&&&
.name&&& =
"pxa27x-keypad",
.owner&&& =
THIS_MODULE,
ANDROID_ROOT 为环境变量，在android的命令模式下通过 printenv 可以知道它为： system
所以 keylayoutFilename 为：/system/usr/keylayout/pxa27x-keypad.kl
pxa27x-keypad.kl 定义了按键映射，具体内容如下：
－－－－－－－－－－－－－－－－－－－－－－
# NUMERIC KEYS 3x4
key 83 POUND
key 55 STAR
# FUNCTIONAL KEYS
MENU&&&&&&&
WAKE_DROPPED
BACK&&&&&&&&&&
WAKE_DROPPED
HOME&&&&&&
DEL&&&&&&&
CALL&&&&&&&
WAKE_DROPPED
ENDCALL&&&&
WAKE_DROPPED
DPAD_CENTER&&&&
key 115 VOLUME_UP
key 114 VOLUME_DOWN
－－－－－－－－－－－－－－－－－－－－－－
如果没有定义键盘映射文件，那么默认使用系统的 /system/usr/keylayout/qwerty.kl
可以修改 /system/usr/keylayout/qwerty.kl 文件改变Android公司的按键映射。
device-&layoutMap-&load(keylayoutFilename)
调用的是文件：
KeyLayoutMap.cpp (frameworks/base/libs/ui)中的函数：
status_t KeyLayoutMap::load(const char* filename)通过解析
pxa27x-keypad.kl
把按键的映射关系保存在 ：KeyedVector&int32_t,Key&
当获得按键事件以后调用：
status_t KeyLayoutMap::map(int32_t scancode, int32_t *keycode,
uint32_t *flags)
由映射关系 KeyedVector&int32_t,Key& m_keys
把扫描码转换成andorid上层可以识别的按键。

Object used to report key and button
Each key press is described by a sequence of key events. A key
press starts with a key event with . If the key is held sufficiently long that
it repeats, then the initial down is followed additional key events
and a non-zero value for . The last key event is a
for the key up. If the key press is canceled,
the key up event will have the
Key events are generally accompanied by a key code
scan code ()
and meta state ().
Key code constants are defined in this class. Scan code constants
are raw device-specific codes obtained from the OS and so are not
generally meaningful to applications unless interpreted using the
. Meta states describe the pressed state
of key modifiers such as
Key codes typically correspond one-to-one with individual keys
on an input device. Many keys and key combinations serve quite
different functions on different input devices so care must be
taken when interpreting them. Always use the
associated with the input device when
mapping keys to characters. Be aware that there may be multiple key
input devices active at the same time and each will have its own
key character map.
As soft input methods can use multiple and inventive ways of
inputting text, there is no guarantee that any key press on a soft
keyboard will generate a key event: this is left to the IME's
discretion, and in fact sending such events is discouraged. You
should never rely on receiving KeyEvents for any key on a soft
input method. In particular, the default software keyboard will
never send any key event to any application targetting Jelly Bean
or later, and will only send events for some presses of the delete
and return keys to applications targetting Ice Cream Sandwich or
earlier. Be aware that other software input methods may never send
key events regardless of the version. Consider using editor actions
if you need specific interaction with
the software keyboard, as it gives more visibility to the user as
to how your application will react to key presses.
When interacting with an IME, the framework may deliver key
events with the special action
that either specifies that single
repeated key code or a sequence of characters to insert.
In general, the framework cannot guarantee that the key events
it delivers to a view always constitute complete key sequences
since some events may be dropped or modified by containing views
before they are delivered. The view implementation should be
prepared to handle
and should tolerate anomalous situations
such as receiving a new
without first having received an
for the prior key press.

kinds of input devices and sources represent keys and buttons.
Nested Classes
advanced key dispatching, such as long
value: the key has been pressed down.
value: multiple duplicate key events have
occurred in a row, or a complex string is being delivered.
value: the key has been released.
When associated with up key events, this indicates
that the key press has been canceled.
Set when a key event has
set because a long press action was
executed while it was down.
This mask is used for compatibility, to identify
enter keys that are coming from an IME whose enter key has been
auto-labelled "next" or "done".
Set when a key event has been synthesized to
implement default behavior for an event that the application did
not handle.
This mask is set if an event was known to come
from a trusted part of the system.
This mask is set if we don't want the key event to
cause us to leave touch mode.
This flag is set for the first key repeat that
occurs after the long press timeout.
This mask is set if the key event was generated by
a software keyboard.
when this event's key code is still being
tracked from its initial down.
This key event was generated by a virtual
