<title>My computer will not turn on</title>

There are a number of reasons why your computer will not turn on. This topic

gives a brief overview of some of the possible reasons.

<section id="nopower">

  <title>Computer not plugged in, empty battery, or loose cable</title>

  
Make sure that the power cables of the computer are firmly plugged in and

  the power outlets are switched on. Make sure that the monitor is plugged in

  and switched on too. If you have a laptop, connect the charging cable (in

  case it has run out of battery). You may also want to check that the battery

  is correctly fitted in place (check the underside of the laptop) if it is

  removable.

  <title>Problem with the computer hardware</title>

  
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.

<section id="beeps">

  <title>The computer beeps and then switches off</title>

  
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.

<section id="fans">

  <title>The computer fans are spinning but nothing is on the screen</title>

  
The first thing to check is that your monitor is plugged in and turned

  on.

  
This problem could also be due to a hardware fault. The fans might turn on

  when you press the power button, but other essential parts of the computer

  might fail to turn on. In this case, take your computer in for repairs.
