This guide will provide information with simple steps for laptop troubleshooting in the right direction
What is Laptop Troubleshooting?
Laptops have always been convenient and can be used at different places because of their portability. Like the desktops, laptops may develop problems which need diagnostics.
It becomes difficult especially when you have no idea of what to do in case of a blank screen or failure.
The problems usually arise from both the software and hardware, and it is always important to determine the cause of the issue before determining the solution.
The laptop has been designed to operate in a similar way to desktops only that the hardware has been minimized to fit perfectly in the little space provided.
They may not be similar in appearance, but they were created to work the same in executing different functions on your device.
Laptop troubleshooting requires patience and keen observation on the problems affecting your computer.
There are several actions you can perform to ensure your laptop is running regularly and that you can use it without any problems.
It is always important to be careful when handling your laptop since it has more delicate parts just like any other computer. In this review, we will look at some of the problems you are likely to encounter when using your laptop.
We will also give you a step by step procedure of detecting and finding solutions to the problems.
Laptop troubleshooting Guide
Laptops are just the same as your desktop computers, except that they are smaller and portable.
There really isn’t much difference in the functionality between desktops and laptops either. However, many people are wary about troubleshooting their laptops because of their complex structures.
To know the importance of this guide , let us take an example , suppose your Laptop is not working, you will start checking its battery and other things but fault could be different. this is where Laptop Troubleshooting comes into use.
Laptop troubleshooting with blank screen
There are times when your laptop fails to show anything on the screen despite the fact that you switched on the power button, the LED lights are lit, and you can also hear the sound of the cooling fan.
The possible problem is the failure of a single memory module. The first step is to ensure the memory modules are in contact with the slot by resetting.
It can be done by making replacements on the memory modules. Sometimes replacing or resetting may fail to work.
You will need to dissemble the laptop before reassembling everything again.
It involves removing the modem, wireless card, hard drives, DVD drive and other hardware to the bare minimum.
Once you manage to put everything in order but still nothing happens, then you will need to purchase a new processor or motherboard.
A blank screen usually occurs with a failed processor or motherboard.
My computer is turn off completely
There are situations where you try switching the power button or connecting your laptop to its charger, but nothing works. The power LED lights are off, and the fan is also constant.
It may mean that the battery is empty and that the AC adapter has failed to transmit electric current.
In this situation, purchasing a new charger is usually preferable rather than repairing to avoid future problems.
The problem might also be that the motherboard cannot receive any power because of a failure from the DC jack. If it so happens, then you will need to purchase a new DC jack.
There are situations when the DC jack is operational, but the problem originates from a failed motherboard.
In this case, you need a new motherboard since it is always difficult to repair the problem as it needs the expertise of the manufacturers.
Laptop troubleshooting if it shuts down unexpectedly
It is often called freezing which means that your notebook goes off without giving you any warning. Before it closed, the cooling fan was a bit louder, and the bottom felt hot. The possible problem is related to your computer’s cooling system.
The reason is that your processor is not cooling in a proper way and that the dust is clogged in the fan heat sink. You can begin by cleaning the heat sink to remove the dust.
To access the heat sink, you need to remove the cooling module, but it would depend on the type of laptop you have.
You will find a lot of dust clogged inside and a thorough cleaning can help fix the problem of overheating.
Constant noise once I power on my laptop
There are moments when you turn on your notebook, and you can access anything, but you get irritated by a constant rattling noise.
The possible issue may be arising from your hard drive or the cooling fan. It can be caused by the hard drive in situations where you find the laptop makes noise, but the fan is not spinning.
To solve the problem, you first need to perform a backup to secure your important files and documents.
Start by ejecting the hard drive the reconnecting and power on your laptop. If it is still persistent, then you will have to replace your hard disk with a new one.
Ignoring the problem will cause it to shut down at some point in time, and you stand a chance of losing all your important documents or files.
A distorted or strange image on the screen
You might have powered on your laptop, but upon reaching your interface, you see a garbled image or weird colors on the screen.
A failed graphics card might have caused the problem. It cannot support the different displays or screen resolutions configured on your computer.
You can begin by performing a test using an external monitor. If the distorted images still appear then you are sure of the failure originating from a bad graphics card.
If it shows clearly on an external monitor but presents it differently on your screen then probably you have a weak connection between the motherboard and the video cable.
Several failures might have occurred in this context as it can either be a failed graphics card, screen, or the video cable.
A bad video can result from several factors, and some may prove difficult to fix. If it happens that you cannot recover the initial display, then you need to determine the parts with the problem before replacing them with new ones.
An external monitor can always be used to test the strange colors. You can also fix this issue by resetting the LCD cable connector situated on the motherboard.
The simplest thing to do when the laptop screen isn’t working is to drain any excess charge from the laptop and then restart it. It is possible that the memory chip or the ram may have been corrupted.
If that’s the case have the RAM chip changed or just change the RAM slots.
This corrects the display problem on most laptops. It’s always a good idea to have an extra RAM chip in the house for this reason if this doesn’t work, sync and external monitor to the laptop.
To do this, you can just connect the laptop to an external monitor and press the toggle key –F4-F10.
This is an emergency step, and ensures that you can somehow get your work done, even though the laptop display stops working.

Liquid spilled on Laptop
It is usually dangerous to spill any liquid on your laptop because it may cause severe impacts on different parts of your laptop.
If the liquid pours on your device, you need to switch it off immediately and eject the battery.
Never attempt to fix them until all parts have been checked for damages caused by the spills.
You can still recover your laptop after a further screening to determine whether all the elements are operational.
All parts should be tested separately before being reassembled. Some laptops usually go off completely since the damages affected most parts of the computer.
It is common for some keys to stop working and several possible issues might cause this situation. It might be a technical problem resulting from excess pressure when punching the keys.
It can also be caused by clogged dust within the keys making it difficult to replace them. In situations where most of your keys are missing, or they are not functional then the only solution to the problem is to find a new keyboard.
It is usually difficult to determine the underlying cause of the fundamental failures because of the different designs of keyboards.
Lost keyboard key
Replacing the keys is easy but could get very tedious. Get yourself a new key (you could buy one online that around $2-$5). Then carefully pry back one key and analyze how it is properly set.
Once you have an understating on how one key is set, just apply what you have learned to replace the missing key/s.
Keyboard not working
If the keyboard isn’t working, first shut down the laptop and start it again after a few minutes. Then use system restore, which solves most keyboard related issues.
If it still doesn’t work, check if there is an issue with the drivers –are they updated or not? If not, update them and then restart the laptop again.
The keyboard should work now. If the keyboard is still not working, type “device manager” in search. Open device manager.
Here you will find the keyboard icon, right click on it and use the “scan” the option. Check for hardware changes, and follow the instructions that show up on the screen.
A constant sound which beeps when booting
During startup, you may experience a problem where there is no display on your screen, but there is a sound which beeps continuously. It can be caused by pressing more than two keys at once.
The possible problem is that the keys are stuck and your laptop cannot perform different actions all at once.
You can diagnose the problem by removing the keyboard and checking to ensure all keys are in their right positions before placing it back again.
Sometimes you can re-press the stuck key for it to return it to the correct position but it is just a temporary solution and might not work in other cases.
Battery is not charging typically
There comes the point when your battery needs adjustments of the plug in the power connector to charge. It may also fail to charge completely, and the possible problem may be a weak DC power connector or a failed battery.
First, switch off your laptop before removing the battery. Connect the AC adapter directly without the battery and check if it is working. You can also remove the battery and place it back again to see if the problem persists.
If it operates efficiently when connected without the battery but shows problems once the battery is intact then you need a new battery.
In situations where the battery is charging after making adjustments on the DC power connector plug then the failure may be originating from the DC jack. A new one will be effective in solving the problem.
Laptop headphone jack not working
If the laptop headphone doesn’t work, go to the control panel, once there, go to hardware and sound and then to sound.
Here, you will find an option called mange audio devices. Now, plug in your headphone to the laptop and check if they show up next to the “mange audio devices” option.
If the headphones are not visible, then there is an issue with the drivers.
Either a driver is missing or there is a problem with the headphone jack itself. If the issue is with the drivers, use windows update. Windows update detects all missing drivers.
Next step is to go to the manufacturer’s website and get the driver reinstalled.
Laptop troubleshooting if touch-pad not working
There is simple Laptop troubleshooting step if the touch-pad doesn’t work; perhaps there is a problem with the touch-pad’s sensitivity. May be it has been set too high. So you will have to lower the touch-pad’s sensitivity first.
But the easier thing to do is simply to clean the touch-pad. Clean it perfectly using a lint free cloth.
This solves many issues, as it is often the dirt that has collected on the touch-pad that makes it doubly difficult for the laptop to detect your fingertip, often leading to very random cursor movements.
If this doesn’t solve the problem, it is possible that the problem is with the touch-pad drivers. May be they haven’t been updated yet or contain bugs that cause random movements to occur.
Check the manufacturer’s website and download the latest versions of the drivers and get them installed on your laptop.
Once common mistake people make is to turn off the touch-pad by using the laptop’s function keys. Correcting this is very simple- just hold on to the Fn key and press the function key which has an icon on it that looks like a touch-pad.
Laptop mouse not working
If the Laptop mouse is not working, first check the USB connection. Often, a loose USB connection is the reason for the mouse to stop responding. Now plug in the mouse USB to another port on the laptop and check if it works or not.
If it still doesn’t work, unplug all USB devices from the laptop and restart it. Now connect mouse to the laptop and check it works or not.
Connect the mouse to another computer as well, and find out it works or not.
There could be a problem with drivers, so use windows update to find out if the mouse drivers are not functioning. If that is indeed a case, get the drivers from the manufacturer’s website and reinstall them.
Laptop not connecting to WI-FI
If the WI-Fi is not working, then type “network connections” in the search box.
Once at network connections, you will find the icon for the wireless connection. Just right click on it and select “Enable”.
If it still doesn’t work, check the SSID as well as wireless router’s security key.
If there is still a problem, restore the router to default factory setting and reinstall the drivers for the wireless adapter. This should solve the problem, if not; get help from a laptop technician.
Laptop troubleshooting has been most common today and there are problems which you can fix them alone without requiring an expert.
It is always important to be careful with your laptop by performing occasional clean-ups and taking good care when handling it.
Most users have managed to stay with their laptops for quite a long time without experiencing technical problems because of their way of dealing with a computer.
Laptop troubleshooting involves performing step by step procedures to find the underlying problems in your computer and how to solve them.
