Hello Friends, hope you are all fine!
It can be a traumatic experience when you’re laptop doesn’t turn on, particularly when you rely on it as your primary device.
You need to take a deep breath in order to know what the potential causes might be. If your laptop is not starting then you can fix this problem by following one of the six steps below in which we've included information on how to hopefully get up your laptop working and running again.
Step 1: Check power supply
You have encountered one of the most common problems. Various things can go wrong such as using the wrong laptop power supply that delivers the wrong voltage to a blown fuse in the plug. So check whether the adapter is indeed the correct one you are using for your laptop that delivers the right voltage and amps. You can confirm this by stickers or markings on both sides of the power supply and laptop. You need to have some third-party chargers for your output power at a speed that is only equivalent to what your device requires to run. Particularly older devices can lose significant amounts of battery when in sleep mode and may therefore need not turn on if one of these chargers are used.

Many laptops from the same manufacturer use the same size plug and if you own more than one then it’s not too difficult to plug in the wrong power supply which might provide a different voltage or not enough current.
Check the fuse in the plug if it's the correct charger. For removing the fuse use a screwdriver and swap it for one that’s known to be good. Your spare power cable will plug into your power supply which is a much quicker way to test that it isn’t the fuse of the fault.
Check the wire itself since power supplies get beaten up, especially if you carry them everywhere. There are weak points at the ends where they join the black brick and at the plug which connects to the laptop. If you see the colored wires inside the black outer protection then it could be time to buy a new power supply unit (PSU).

Step 2: Check the screen
Disconnect external displays including projectors and monitors and make sure that they're not stopping your laptop from booting into Windows.
Your computer's power LED lights are up and you can hear the noise of hard disk or fans whirring and there’s no image on the screen then make the room dark and check whether there is a very faint image on the screen.
You may think it easy that your laptop isn’t booting but in fact, it’s your screen that’s the problem.
A faint image appears on the Windows logon screen then the inverter could have failed, however, this applies only to old laptops before LED backlights came along.

It’s crucial for you to buy the right replacement part since replacing an inverter is difficult. You can’t afford to get it wrong as inverters aren’t exactly cheap. Professionals can very well handle this job since your laptop is likely to be old and it's probably time for you to buy a new one.
Your laptop is booting fine, but there’s no image at all then there must be a fault with your LCD panel. Therefore replacing a laptop screen is possible but difficult since the screens can be costly.
Step 3: Unplug and removable USB drives or memory cards
Assuming that everything is ok with the screen and power supply your computer may get stuck before it loads the Windows. The classic culprit here is the memory card or USB drive which is left inserted into the card reader or USB port. You'll then typically see an error message such as "Operating system not found" which leads to unnecessary panic.
Most of the time, the BIOS is set to try booting from removable storage drives including the cards before the internal hard drive.
Also, check for the disc left in the DVD or Blu-ray drive.

If none of the above works then you can try booting from a USB drive or rescue disk.
If you have then use the Windows DVD or otherwise you can download it using another computer from a rescue disc image that either burns it to a CD or DVD or extract it from a USB flash drive. Then attempt to fix the problem with Windows by booting from this.
If the cause of your problem is a virus then rescue the disc from an anti-virus provider as this will include scanning tools that can find and remove the malware.
Step 5: Boot into Safe Mode
You might be able to get into safe mode even if you can’t boot into Windows. You’ll get a menu offering to boot into Safe Mode by pressing F8 as your laptop is starting up. Then you can enter into safe mode. If this won't work in Windows 10 though then you need to be in Windows before you can get into the safe mode. Then, in that case, you'll need to boot from a drive or rescue disc as described above.
You might be able to undo any changes that caused your laptop to stop booting if you can enter safe mode. You could then try uninstalling any new programs that you have recently installed by uninstalling a driver which was recently updated and then create a new user account if your account is corrupt.
Step 6: Check for faulty or incompatible hardware
If a newly installed memory or another piece of hardware might be preventing your computer from booting then remove it by reinstalling the old memory if necessary and then try again.
Your motherboard has LED readouts that show POST codes then search it in manual or online to find out what the code shown means.
It can be often tricky to get a newly built laptop to boot. The best tip we can give you is to disconnect everything except the bare minimum needed to boot to the BIOS:
· CPU with heatsink attached
· Graphics card if there's a graphics output on the motherboard then remove any plug-in graphics cards
· One stick of memory. We recommend you remove and leave the single stick in slot 0 or whichever is mentioned in the manual.
· Power supply
All other hardware is unnecessary since you don't need a hard drive, optical drive, or any other components for your laptop to start.
We hope this blog will be useful for laptop users who face problems while starting their laptops and how to fix that problem.
