At last I got the solution, you can achieve this by deleting system/bin/charge_only_modefile. Please do that at your own risk and before deleting have backup of that file. I got the desired result that was boot when its connected to wall charger and now its working fine.
All the best!
最后我得到了解决方案，您可以通过删除system/bin/charge_only_mode文件来实现这一点。请自行承担风险，并在删除之前备份该文件。我得到了想要的结果，当它连接到壁式充电器时启动，现在它工作正常。祝一切顺利！

Get your device into the bootloader (fastboot) and run the following command from a computer connected over USB with Android Tools:
将您的设备放入引导加载程序 (fastboot) 并从通过 USB 连接的计算机上运行以下命令并使用 Android 工具：

I was able to get it to work by updating the init.rcfile
我能够通过更新init.rc文件来让它工作
I found the on chargertrigger and added the following lines below it:
我找到了on charger触发器并在它下面添加了以下几行：
setprop ro.bootmode "normal"
setprop sys.powerctl "reboot"
The entire trigger block ends up looking like this
整个触发器块最终看起来像这样
on charger
class_start charger
setprop ro.bootmode "normal"
setprop sys.powerctl "reboot"
You then need to repack and flash the boot image created after the updates.
然后，您需要重新打包并刷新更新后创建的引导映像。
Connect the device over USB
通过 USB 连接设备
Power on device and get to bootloader mode
打开设备电源并进入引导加载程序模式
adb reboot bootloader
To flash boot image execute the following command while in fastboot
要闪存启动映像，请在 fastboot 中执行以下命令
fastboot flash boot new-boot.img
Note: This fix will cause the device to reboot when its plugged in even when shutting it off using the power button or software shutdown.
注意：此修复将导致设备在插入时重新启动，即使使用电源按钮或软件关闭将其关闭。

I also tried replacing charge_only_mode with a sh script that rebooted the phone but only got a red circle with the M (on a Motorola Bionic). Changing the script to the below got it working...Now I get the red circle with the M for a few seconds, then a blank screen, the another red circle with the M, and it boots on up.
我还尝试用重新启动手机的 sh 脚本替换charge_only_mode，但只有一个带有M的红色圆圈（在摩托罗拉仿生上）。将脚本更改为以下内容使其正常工作......现在我得到了带有 M 的红色圆圈几秒钟，然后是一个空白屏幕，另一个带有 M 的红色圆圈，然后它启动了。
#!/system/bin/sh
su -c "/system/bin/reboot -n outofcharge"

For Lenovo A2010 phone,following worked:
对于联想 A2010 手机，以下工作：
- Use file manager phone app from playstore like Total commander(on rooted phone) to goto folder /system/bin/
- Copy file kpoc_charger and paste it there as kpoc_charger.bak
Now edit the original file kpoc_charger using total-commander, replace all lines with following code:
#!/system/bin/sh /system/bin/reboot- Save it, goto properties and change UID:0 root, GID:2000 shell and permission as 755 (same as properties of other files in /system/bin folder).
- Now shutdown phone and plug to charger.
- Bazinga!!!! battery icon shows for a sec but phone sucessfully boots into os.
- 使用 Playstore 中的文件管理器手机应用程序，如 Total Commander（在有根手机上）转到文件夹 /system/bin/
- 复制文件 kpoc_charger 并将其粘贴为 kpoc_charger.bak
现在使用 total-commander 编辑原始文件 kpoc_charger，用以下代码替换所有行：
#!/system/bin/sh /system/bin/reboot- 保存它，转到属性并更改 UID:0 root、GID:2000 shell 和权限为 755（与 /system/bin 文件夹中其他文件的属性相同）。
- 现在关闭手机并插入充电器。
- 巴辛加！！！！电池图标显示一秒钟，但手机成功启动到操作系统。

I found another way for this (thanks to DavidThompson256 http://forum.xda-developers.com/showthread.php?t=1187631)
我为此找到了另一种方法（感谢 DavidThompson256 http://forum.xda-developers.com/showthread.php?t=1187631）
First make sure your phone is rooted (which I found iRoot very good for this), then install RootExplorer.apk (or similar) on your phone.
首先确保您的手机已植根（我发现 iRoot 对此非常有用），然后在您的手机上安装 RootExplorer.apk（或类似的）。
Try to edit "/system/bin/playlpm" and replace its content with following commands: (do not forget to make a backup first).
尝试编辑“/system/bin/playlpm”并用以下命令替换其内容：（不要忘记先进行备份）。
#!/system/bin/sh
/system/bin/reboot
(I know the content is in binary, simply remove them and write those two lines and save the file)
（我知道内容是二进制的，只需删除它们并写入这两行并保存文件）
NOTE: When you modify that file, no changes will be applied on its permissions but if you are making another file remember to set permissions exactly as it was.
注意：当您修改该文件时，不会对其权限进行任何更改，但如果您正在制作另一个文件，请记住完全按照原样设置权限。
Finally, please do it on your own risk. It worked for me. (Samsung Discovery S730M)
最后，请自行承担风险。它对我有用。（三星探索 S730M）

When phone get charging from outlet, I want phone to power up automatically without hitting any power button. (Not Working with wall Socket, but working when connected to USB cable via Laptop).

You can only achieve this by modifying your phone's OS files. Basically there is boot script/binary at /system/bin/chargemonwhich you can replace with a script that does nothing. Do it at your own risk because this may result in the device being damaged permanently. Also, Manufacturer warranty will become void.
您只能通过修改手机的操作系统文件来实现这一点。基本上有引导脚本/二进制文件/system/bin/chargemon，您可以在其中替换为不执行任何操作的脚本。请自行承担风险，因为这可能会导致设备永久损坏。此外，制造商保修将失效。

i think there should be power sensor if you can add that in this code i belive it will work
我认为应该有功率传感器，如果您可以在此代码中添加它，我相信它会起作用

So I was trying to achieve this with a 3rd gen Moto G. It has a charge_only_mode file as per Rohit's answer, but simply moving/renaming it did not make the phone reboot on charge. Instead it just sat there with a Motorola logo. I got the same result when replacing charge_only_mode with either of the scripts referenced here.
所以我试图用第三代 Moto G 来实现这一点。根据 Rohit 的回答，它有一个 Charge_only_mode 文件，但只是移动/重命名它并没有使手机在充电时重新启动。相反，它只是坐在那里，带有摩托罗拉的标志。用此处引用的任一脚本替换charge_only_mode 时，我得到了相同的结果。
I did get it to work, however. I copied /system/bin/reboot into /system/bin/charge_only_mode, and that did the trick.
然而，我确实让它工作了。我将 /system/bin/reboot 复制到 /system/bin/charge_only_mode 中，这样就成功了。
