Why does my computer beep when I switch it on?
Beeps at start-up are the computer telling you which part failed its check. The pattern of long and short beeps points to the part.
It usually needs a technician, but it's rarely an emergency. The checks below are safe to try first.
Does this sound like yours?
- It beeps a few times and nothing shows
What usually causes it
- Memory (RAM) loose or faulty, the most common cause
- Graphics fault
- Keyboard or motherboard fault
Most likely first. A hands-on test confirms which one it is.
What you can safely check
- Count the beeps and note whether they're long or short (for example 1 long, 2 short)
- Record a short video of it starting up
Please don't
- Don't open the case or laptop to reseat parts unless you've done it before
