Is it possible to automatically power on the device once the charger is connected given that the device is initially turned off?

For some Samsung devices, this can be accomplished through NoMoarPowah!:

NoMoarPowah! can automatically reboot into Android when charging is done. Either when fully charged, or when the battery level reaches 15% and Android has enough juice to run.

You need root and you probably don't want to do it unless you really know what you're doing, since I would expect this to modify important system files.

any idea how's this app works ?!. it's model specific i have the code but i can't seem to understand it well, any direction to understand this code so i could get it work on my phone ?! – Muhammad Ghandour Mar 7 '12 at 18:55
@MuhammadGhandour I haven't looked at it myself, but I would assume adapting it would be quite a challenge if you're not already familiar with this sort of thing. One option is to ask Chainfire to support your device, he may be able to add it if you provide him with the info he needs. (As an aside, dev questions are off-topic here.) – Matthew Read♦ Mar 7 '12 at 18:59
i have already requested that at chainfire's channel, rather than xda-developer, Is there any other good place for Android dev questions ?!.. – Muhammad Ghandour Mar 11 '12 at 10:08
@MuhammadGhandour Stack Overflow does development questions, you'll need to ask something specific though rather than "Can you help me understand this?" – Matthew Read♦ Mar 11 '12 at 22:54
actually i was redirected from StackOverflow to here for Android specific question. anyways thanks for your help – Muhammad Ghandour Mar 13 '12 at 8:34

Kernel is loaded at a later stage in the boot-up process, so any modifications to it would not have any effect for when the device is powered off.

This functionality really depends on each device's hardware, most likely in the bootloader (more knowledgeable editors feel free to correct me.) For example, my Motorola Atrix 4G phone begins booting up when I connect a charger, while my Samsung Galaxy Tab does not - it displays the "Battery Charging" graphic and requires being powered on manually.

so what brings up the Battery charging graphic on the screen ?!...now the bootloader is called when you hit on the power button manually, but what piece of code displays the battery charging graph on the screen ?! – Muhammad Ghandour Mar 4 '12 at 9:19
