Hello Guys, Today I will show you How to Fix - When Your Laptop Won't Power On | Causes of a Laptop Not Turning On | WiFi Card Problem

How to Fix It When Your Laptop Won't Power On

1. Check and replace the power supply. This step may seem like common sense but confirm you didn't plug the wrong power supply into your laptop. Many laptop AC adapters look the same. If the adapter doesn't offer the correct voltage and amperage for your laptop, it won't work.

2. Detach from any docking stations and plug the power adapter directly into the laptop.

3. Make sure it's not a screen issue. A common mistake is when the screen itself is black, people assume their laptop is off when it isn't.

4. Make sure all cooling vents are clear. Laptops have special safety circuits to cut power to your laptop if any components overheat—usually the CPU. Overheating can happen for many reasons, but most commonly, it's if you use the laptop on a pillow or sofa—any surface that blocks the laptop cooling vents. Avoid this to keep your laptop cool.

5. Remove any bootable media drives. If you've ever booted your computer from a USB device or DVD, and forgot to remove it, it could cause startup problems.

6. Listen for beep code sounds. When motherboard components fail, often the laptop will issue a series of beeps. The number of beeps is actually a code to help you identify the failed component.

7. Remove any residual electricity by removing the battery, disconnecting the power adapter, and pressing and holding the power button for 30 seconds. Connect the power adapter again, wait 30 seconds, and then turn on the system. If your laptop starts, turn it off again and reinstall the battery.

8. Replace the CMOS battery. The laptop motherboard contains a small circular battery that powers CMOS, which allows the BIOS to load the operating system and all input and output components during bootup.

9. Replace any newly installed components. Did you recently install new RAM cards or a hard drive? If your laptop stopped booting immediately after, it might indicate the new hardware is faulty.
