You need to remove the battery, and then Shift + Control + Option + Power Switch, by 5 seconds. Then, the placement of the battery, plugged in, boot. This trick is very useful to me yesterday for the first time with G3, visit the website at the time, I suddenly wanted to win for the keyboard, the result G3 crash pulled no use by the shutdown, so I took the battery and then loaded on boot, the machine open can not pull. Now solved the problem. Taught this trick off, remove the battery, and then Shift + Control + Option + Power Switch, by 5 seconds. Then, the placement of the battery, plugged in, boot. Thank you.

You need to do following things. If you send startup sound machine, and then no sound, and power indicator light is bright, but a black screen. Help may be the problem of adjusting the screen, the screen may also be finished. If you start the machine did not make a sound, click the switch to off, black darkness. It should check the battery and power. If you use a known good battery or reset the system / power management component still can not get the machine after the start. Check and reply.

Cause the computer a black screen now there are two main reasons, one hardware failure, and second, software conflicts, while the main difference between the two is the location of occurrence of a black screen, that is, when a black screen at boot, or after the normal start the machine, In the process of using a black screen appears.

After the sudden appearance in the boot, "black screen" when the reader first note listen to the computer whether the PC speaker alarm sound. If the PC speaker issued a warning sound, then we can determine the initial length of the sound problems that may occur in the hardware area. For example, if the computer boot a PC speaker alarm sound four short length, then according to this tip can easily determine the problem happened in the display card. If so, the reader can open the case, look at your graphics card is plugged in firmly. If you feel some loose, pull out the graphics card and then re-inserted, seated, then secure it with screws. All the best.

Some computers will not alarm black phenomenon, then the simplest thing is to under Mathematics on the "exclusive method" to analyze specific issues. First check the power strips, if there is a problem related to computer matching parts removed, replaced with some other devices can be used to check the power connection board is working correctly. If power strips, there is no failure, and then the normal procedures for checking the computer power supply and motherboard connection is between normal, that is to check whether the normal power supply board. All the best.
