How Does A Laptop Power Button Work?

..the power button prevents the electricity from going beyond a certain point…

To power on a laptop, you need to ensure there is a battery present or the system is connected to a power source. The power from either of these two sources produces electricity that flows through the circuits within the laptop.

But, the power button prevents the electricity from going beyond a certain point.

However, when the power button is pushed, the outlet opens allowing electricity to flow to the rest of the laptop. When the same button is pushed, the laptop goes back to sleep.

Can I Install A New Power Button?

Yes, you can install a new power button on your laptop once you notice that the previous one has developed a fault. If you want to carry out the installation yourself, follow these steps:

• Step 1: Take out the battery, AC adapter, and back panel
• Step 2: Remove the hard drive and RAM
• Step 3: Remove the keyboard bezel
• Step 4: Take out the keypads
• Step 5: Remove the top frame and look for the power switch
• Step 6: Remove the old switch and insert the new one
• Step 7: Reassemble the laptop

What Does It Mean When My Laptop Fails To Come On?

..If your laptop fails to come on, then it must be facing a hardware fault…

If your laptop fails to come on, then it must be facing a hardware fault. However, this hardware fault maybe as a result of power supply to the system or a fault in other components of the hardware.

Therefore, the first thing you should do is check the power sources (battery and charger) before examining other components.
