How To Troubleshoot A Dead Laptop

This blog will explain how to troubleshoot a dead laptop by resolving the problem. The troubleshooting tips mentioned in this blog are not model or brand-specific.

Let’s look at the different failure scenarios and how to troubleshoot them.

Your laptop is dead. 

When you press the power button by plugging it into the AC adapter, there are no signs of life since it appears dead.

In this case, what can you do?

1. Ensure your wall outlet is working and the outlet is getting power from the AC adapter. Otherwise, try for another wall outlet.
2. test the AC adapter and ensure the voltage output is correct. Then, push the adapter with a voltmeter.
3. If your adapter is suitable, then try reconnecting the battery. Otherwise, remove the battery and wait for 1-2 minutes by plugging in the adapter. Then try turning it on again.

If your adapter cannot pass the test with a voltmeter, replace it with a new one by retesting your laptop. We always recommend buying an original replacement adapter from the manufacturer and not a generic one because there could be more than one adapter available for your model.
The new adapter’s voltage output must be the same as the old one. However, amperage, on the other hand, can be the same or higher.

If your previous troubleshooting steps didn’t help you, your computer may have a problem with the DC jack or motherboard. In this case, you must disassemble the laptop and test the DC jack.

There are normal start-up noises when the computer and the LED lights turn on, but nothing appears on the screen.

Firstly, take a closer look at the screen under bright light. There may be a possibility that your screen may show a very faint image. We recommend that you troubleshoot the backlight failure in this case.

If, on the other hand, your screen shows no image at all, then test the laptop with an external monitor or TV that is connected to the VGA port, DV, I port, or HDMI port.

Toggle your video output between external and internal by using the Fn keys:
–For HP laptops, use the Fn and F4 keys simultaneously.
–For Toshiba laptops, use the Fn and F5 keys.
–For IBM laptops, use the Fn and F7 keys.
For other laptops, different key combinations are used.

The problem can also be related to the external monitor, which works fine, but the internal screen has no image at all:

– There can be a poor connection between the video cable and the motherboard or screen. Then, try reconnecting your video cable on both ends and check if this helps.
– If the screen shows failed, replace it with a new one.
– If your video cable fails, place it with a new one.
– If the motherboard fails.

If both your internal and external monitors show no image, the problem can be related to your failed memory (RAM) and motherboard.

 Then, try reconnecting the memory module, which may not connect well with the slot.
– Then try cleaning the contacts on the memory module.
–Also, try moving the memory module into another slot.
– Then try replacing the memory module with another one.

If two modules are installed, you can try removing them one by one, and if one of the modules fails, then try moving modules from one slot to another.

If reseating or changing memory doesn’t help, then you can try this:
Remove the quickly accessing components such as your battery, hard drive, DVD drive, and others. Then, try turning on your laptop without these components installed.

One of the components may have failed and is preventing the entire computer from starting up properly.

Try turning on your laptop with an external monitor while the video cable is unplugged from the motherboard.

If an external image appears after you disconnect the video cable, there is something wrong with the line, and you need to replace it with a new one.

If your laptop is still dead, try removing other internal components, such as your wireless card, modem, keyboard, etc., and test it with an external monitor after removing each part.

The last step for testing your laptop system is to remove the motherboard from the base and assemble a basic barebone system, which includes the following:
1. A motherboard that, in most cases, has an onboard graphics chip.
2. A CPU with a cooling module.
3. A known suitable memory module.
4. Power button board.
5. A known suitable AC adapter.

If your laptop is still dead and doesn’t turn on, it can be a bad motherboard or a failed CPU.
