STEP 2: Separate Power Button for the MonitorYou may also need to switch on the monitor in order to see what the computer is displaying. A similar power button will usually be found in the lower right hand corner of the monitor screen.
STEP 3: Push the button.
On some computers, the button lights up when the computer is on. On laptops, there’s often a light on the front that comes on. You may have to keep pushing for a couple of seconds to make this happen, but don’t worry – you’ll soon get to know how your computer works.
If nothing happens, there are a few things you can check easily:
If you’re using a laptop, the battery might be flat. So plug in the charger, plug the charger into the mains and let the laptop recharge. You can continue to use it while it’s doing this.
If you have a PC, make sure that the plug or any of the other wires haven’t become disconnected.
Ensure that the monitor is turned on. Most PC monitors have an ‘on/off’ button on the bottom corner of the screen (see below). The button often lights up green when the monitor is on.
Power Strips
Often, a computer is plugged in to a power strip, or surge protector. This helps protect the computer from power fluctuations or lightning storms, and it also allows a person to turn the computer and monitor on at the same time using the power strip on/off button.
Step
1: Find the ‘on’ button. It probably looks like this (but might be
square or oblong!): - See more at:
