macbook pro没有display...

pohose

我的macbook pro 17"没有了display, sound; 但是开机的白色light还有，为什么会这样？
不必换hardware吧？！

makyo1984

是装了windows系统了吗？建议从起进入安全模式去看一下

刚买的？开机有没有声音？是当机还是荧幕报销？如果是当机可以试用Install Disc 2(如果没有就用Disc 1)，然后按着忘了C还是D，进入Hardware Test模式测试一下是不是其他的问题。

牛牛好累

楼主的 MacBook Pro 用了多久？

如果以下 3 种动作都不能改善。就表示楼主的逻辑电板可能烧坏了。
建议还没刷机前拆出主机硬盘，看可不可以进行备份。

选择 1：

Resetting PRAM and NVRAM
1. Shut down the computer.

2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.

3. Turn on the computer.

4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.

5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.

6. Release the keys.

Your computer's PRAM and the NVRAM are reset to the default values. The clock settings may be reset to a default date on some models.

如果以上不能解决楼主的问题，这是选择 2：

Resetting PowerBook and iBook Power Management Unit (PMU)
Resetting the power manager also resets date and time settings.

1.  Force Quit (Option-Command-Escape)

2. Restart (Control-Command-Power)

3. Force Shut Down (press the power button for 10 seconds)

选择 3：

放弃所有资料，刷机。
