A PC or laptop has several phases of “ just won’t start.” The problem is then compounded because a laptop unlike a desktop personal computer has two power sources, when DC isn’t available, electricity is drawn from the laptop’s battery.
So you incontinently know that when the laptop doesn’t turn on, you have a power source issue. However, if you have a power source issue, the laptop appears dead, below is how you troubleshoot your laptop PC:
Check to ensure that the laptop is plugged in.
Check to ensure that the battery is duly installed correctly and clicked in place.
Try removing the battery to run the laptop from just the DC power ( please note desktop personal computers do not have a battery unless you are looking at the bios battery on the motherboard but that is something for another post ).
In this case, you may have an imperfect battery that needs replacing, If it works. ( You can check our previous post here if you are wondering how to check the battery )
DC cord adapter issues
Check the power brink on the DC cord. Is it the right connection for your laptop? Other movable biases may have analogous-looking appendages, but unless they match the volts and amps for your laptop, the laptop doesn’t work. (Not that this has ever happened to me.)
Check the lights
When the laptop’s power LED is on, it shows that the laptop has some life. It means that the laptop’s inner hardware is displaying that it has power. The problem could also lie with the laptop’s interior hardware, not with the power alone.
When your laptop has separate lights for the DC power and battery, you can check both. However, it’s a battery issue, If the DC LED lights up but the battery doesn’t.
When the battery LED is lit but the DC LED remains dark, the DC power brick might be dead or the DC power from the wall might be meddled up ( fuse blown / faulty lead ) or you might have a connection issue.
Testing other hardware
Still, you can try testing some hardware, If you consider yourself to be technically competent. For illustration, if the laptop has removable drives or RAM compartments check to ensure that they’re duly connected and clicked into place.
With the laptop’s power off ( lead removed and unplugged along with the battery removed ) take out the laptop drives and put them back by again. Ditto for the PC’s memory card or RAM Turn off the laptop, remove the memory, and also put the memory back.
Laptops don’t start when they’re broken just like personal computers. I’m not being clever here, Laptop hardware can simply fail ( more so than desktop computers due to the extra heat exposure created due to design ).
Failed electronics are covered by most laptop or personal computer guarantees at least those bought from good companies. ( we offer a minimum of 3 Years on all our computers free as standard )
You need to get support by reaching the laptop manufacturer. ( If you are still within warranty, if not consider contacting a PC specialist like ourselves here )
Could it be related to the display?
Press the Caps Lock key. The Caps Lock LED on the laptop will blink on and off as you press the key, If you have power. However, the problem could be the display.
If so, check the laptop display’s brightness settings. However, the screen will be dark, especially in a bright room or in direct sun, If the brightness position is turned down too much.
Try turning up the brightness all the way to see whether the screen glows. ( Some laptops have buttons for this near the keyboard that can be accidently touched )
Plug an external display into the laptop’s display port. If this works the problem is with the laptop’s display only, not with the laptop’s display adapter or other internal hardware.
Because the laptop and display are the same things, fixing the display (or the display adapter) involves replacing major laptop factors.
You must return the laptop to the dealer for this if again you are under warranty or consider contacting a specialist like us using the live chat in the bottom right of this page.
