# 我的计算机不能开启

有多种原因造成计算机不能开启，本主题简要给出一些可能的原因。

# 计算机没有插电，电池没电或者电源插头松了

确保计算机电源插头牢固接在插座上，并且电源是通的，确保显示器接好也是打开的。如果是笔记本电脑，连接上充电插座(以免电池没电)。您还可以检查电池是否正确接入(检查笔记本的一边)。

# 计算机硬件错误

A component of your computer may be broken or malfunctioning. If this is the case, you will need to get your computer repaired. Common faults include a broken power supply unit, incorrectly-fitted components (such as the memory or RAM) and a faulty motherboard.

# 计算机报警然后关闭

If the computer beeps several times when you turn it on and then turns off (or fails to start), it may be indicating that it has detected a problem. These beeps are sometimes referred to as beep codes, and the pattern of beeps is intended to tell you what the problem with the computer is. Different manufacturers use different beep codes, so you will have to consult the manual for your computer’s motherboard, or take your computer in for repairs.

# 计算机风扇在转，但是屏幕上无显示

首先检查显示器插头是否接好，开关是否打开。

这个错误也可能是硬件问题，当您按下电源开关风扇通电，但是其他重要部分开启失败，如果是这样，请送去维修。
