The fix: When your computer won’t turn on

Well, here are some basic things to do when your computer won’t turn on when you press the power button before we move on to the more complex troubleshooting.

Initial checks

1. First, check if your computer is turned on. As simple as it may sound, you might not have turned on your computer after all if you hadn’t hit the power button or switch.

2. Check and test your diet for problems. Your computer’s power supply should be active if you see the light on the back or side of your laptop. If you press the power button and nothing happens, the most likely cause is a power outage.

3. If the computer does not turn on and your power supply is working properly, check that the charger is connected correctly and from the correct port. Since not all USB ports provide power, make sure the port you are using is compatible.

4. Make sure that your computer’s AC adapter provides the correct voltage and current. Your computer will not get the proper power if it is not the same. Be sure to plug it directly into an outlet rather than an extension cord.

5. Remove the battery from your computer and see if that helps. Changing the battery is the only solution if your computer is on.

6. Make sure your computer’s power outlet is free of dirt, debris, or damage, such as broken or bent pins, that may have built up there. These problems may prevent the computer from receiving or charging its battery.

September. Make sure that the computer’s cooling vents are not clogged with dust or debris. Overheating and sudden shutdown are possible when the openings are clogged, whether due to dust or other foreign objects.

What if the computer does not start after turning on the power?

Check your screen

Your computer black screen may make you think it won’t start. First, you’ll want to play with the brightness of your screen.

Unplug your second monitor, if you have one, and make sure your desktop is visible on your computer’s home screen. You can also try using a different monitor to see if your computer monitor is the problem.

Check display adapter

The display adapter may be the cause if the computer’s power keys and keyboard are turned on, but the screen is black. The adapter may need to be checked and replaced by an IT professional.

In addition, the Microsoft Wireless Display Adapter It must be connected to the USB charging port on your screen, and your computer must have the latest software updates installed to function properly.

Disconnect your docking station

Use an AC adapter connected directly to your computer if you are using a docking station. The power supplies and ports of the docking station may malfunction, which can cause problems when starting the computer.

The docking station must be replaced if the computer starts after disconnecting the docking station.

Remove the bootable media drive

If you used a DVD or USB drive to create a bootable drive, remove the drive from your computer and restart it. In some cases, the computer may not start properly if the hard drive is left in place.

Also unplug any other peripheral devices connected to your computers, such as a wireless keyboard and mouse, and any printer or scanner connected via a USB cable. Make sure your computer is on with nothing but a power cable, keyboard, and monitor connected before you proceed.

If you recently installed a new device, uninstall it and see if it works. Otherwise, this is a sign that the new device is not working properly.

Listen to the buzzer codes

When a motherboard component fails, your computer often starts with a series of beeps.

For example, a single beep may indicate that all is well, but a long, continuous beep may indicate that the power supply is critical.

Also, if your computer’s motherboard starts beeping, look for long or short beep codes that can help you identify the problem. Check your computer’s manual, hardware manufacturer’s website, or technical support to determine the problem based on the number of beeps.

Restart your computer

If your computer shuts down unexpectedly without warning or error message, it is best to turn it off. Under these circumstances, the motherboard’s security system may have detected a short circuit and cut off the power to protect the internal components.

• Remove the battery and unplug the AC adapter.
• Now hold down the power button for 15-30 seconds.
• Wait another 30 seconds after plugging in the power cord before turning on the computer. Finally, turn off the gadget and reinsert the battery if it restarts.

Replace the CMOS battery

The CMOS battery and main battery power all the functions of your computer.

A CMOS battery is usually the size of a coin and is located on your computer’s motherboard. In addition to booting the BIOS, the battery also has a limited lifespan and is prone to failure.

The following signs indicate a faulty CMOS battery:

Starting the computer is a chore, and in some cases the computer won’t start at all.

1. Continuous beeps from the motherboard.

2. The date and time are reset.

3. Devices that do not respond.

4. Device drivers disappear.

5. You cannot connect to the Internet.

When the computer’s CMOS battery runs out, the BIOS firmware will also shutdown and restore the system to its factory settings.

As part of the CMOS battery replacement process, you will need an ESD mat and compressed air. Remove and replace the CMOS battery following the instructions below.

Consider hiring a qualified IT professional if you cannot perform this task on your own. You can also use an anti-static wrist strap or wipe your hands with a metal surface to dissipate static charges.

1. To get started, unplug your computer from the power source by unplugging all of its wires and accessories.

2. Remove the computer case with a screwdriver. Do not lose the screws by keeping them in a safe place.

3. Remove the main battery from the computer so that it does not turn on while you are working on it.

4. The motherboard is the next item on the list. At this point, great care must be taken to avoid damaging this component and thus the computer. Ensure that other components such as motherboard cables, graphics card, RAM, and processor heat sink are properly installed on the motherboard.

5. Locate a CMOS battery, which is round and shiny like a coin or button and usually fits into a small holding socket. Note the orientation of the old CMOS battery in the holder before removing it.

6. Get the new CMOS battery and insert it into the same retaining socket in the same direction as the old battery.

September. Replace the main battery and reconnect the external computer case, tightening all screws.

8. Now turn on your computer by plugging it back into the wall outlet. Generally use the computer if it is working after resetting the date and time and reinstalling the missing drivers.

Use a live CD to scan for viruses
