For a PC keyboard, unplug before you start; for a laptop keyboard, make sure it is turned off and remove the battery (refer to your manual for how to do this).

PC or laptop

Turn off your computer. Bend the end of the paper clip outwards, so that you have a straight section of wire. Look closely at the front panel of your CD or DVD drive – you should see a tiny hole.

If your CD/DVD drive takes more than a minute to recognise a disk, or your burner is starting to fail when you create discs, you need to take action.
