Why does my Laptop not turn on?
Your laptop's power button is pressed, but nothing happens. When your laptop doesn't turn on, there aren't many technological hiccups more annoying. You are not required to accept that your laptop has died too soon. You'll discover how to identify the problem and fix it.
If your laptop doesn't turn on, the problem could be with the power source, the hardware, or the screen. In many instances, you can solve the issue by buying various replacement parts or changing the settings on your laptop.
1. Verify the battery and power source.
Check the power supply first if your laptop won't turn on even with the plug-in. You could experience a wide range of problems with the power supply.
It might, for instance, be as simple as using the wrong charging cord, which would result in improper voltage, or it might be that the power source has broken.
1. To determine if the power source is the issue, completely remove the laptop's battery.
2. After that, join your laptop to an active outlet.
3. Try plugging in a different device to see if it works; if it does, the outlet isn't the issue.
4. Your battery, not the power supply, is the issue if your laptop powers on even without the battery.
5. You can manage with AC power until you can afford a new one, which you will need to do.
6. It's acceptable to use your laptop without the battery inserted, but you'll always need to have it hooked into an outlet.
Battery for CMOS
Another test approach is to replace the CMOS battery, which the motherboard needs to store the BIOS settings. This is especially true if you're using an outdated laptop that you frequently turn off or use without the main battery. A brand-new CMOS battery can be changed at a reasonable price.
2. Identify issues with screens
You need to perform more troubleshooting if your power supply is working.
To ensure they are not preventing your laptop from starting up, turn off all non-essential external displays, including projectors and monitors.
If the power button is illuminated and you hear fans or other noises, turn the lights off to see if an image is displayed.
Once the lights are turned out, if there is still a faint image, the screen's inverter has failed, and you must replace it.
Your brightness button can also be damaged.
The LCD panel on your laptop could be damaged if it turns on but doesn't display an image. You may read our article about how to fix a broken screen here. It's not difficult. However, getting a new laptop could be more sensible if yours is an older model.
3. Remove all your laptop's devices.
If you need to remember a memory card, DVD, or USB drive, your laptop might not turn on.
The BIOS may become "stuck" because it attempts to boot from a removable storage device. After removing all USB drives and other peripherals, try restarting your computer.
4. Make use of a rescue disc
You can use a rescue disc to start your computer and fix any issues with the Windows operating system you might be having. The scanning tools on the recovery disc will locate any infections harming your computer so you can remove the offending malware.
5. Start in protected mode
If your laptop won't come on, you may be able to get it to operate in safe mode.
You can remove any new drivers or software impacting your laptop while in safe mode. If your primary user account has been taken over, you can create a new one. If you can get to safe mode, you can undo any changes that prevent your laptop or computer from booting. If your laptop won't come on, you may be able to get it to operate in safe mode. You can uninstall any new applications or programs while in safe mode.
If the current user account is corrupt, you might try creating a new one, removing any recently updated drivers, or uninstalling any newly installed apps.
6. Hardware inspection
The last step in diagnosing a power issue is to check your hardware. Your boot issues could be brought on by recently installed hardware, much as a new RAM kit. After installing your new hardware and removing your old gear, you can reboot.
Unfortunately, there are occasions when the hardware in your laptop, such the hard disc, breaks down mysteriously.
If you recently added new hardware, such RAM, your computer might not be able to boot. Remove it, then reinstall the earlier memory and try again.
If your motherboard includes an LED readout that displays POST codes, look up the meaning of the code in the handbook or online.
A newly constructed PC can frequently be difficult to boot. The best advice in this situation is to unplug everything but the absolute minimum required to enter the BIOS.
You just need a:
processor for boards (with heatsink attached)
video card (if the motherboard has a graphics output, take away any plug-in graphics cards)
a single memory stick (remove any additional sticks and leave the single stick in slot 0).
power source (make sure the switch is on)
Monitor (Check the cords properly which are connected to the monitor) (Check the cables properly which are connected to the monitor).
Conclusion:
Sometimes a computer's inability to boot is due to a difficult-to-repair component breakdown. Hard discs are a common source of issues. If you frequently hear a clicking noise or the drive continuously spins up and shuts down, it's broken.
It's time to start again with a new hard drive if you are unable to restart the drive. An SSD purchase is recommended.
