Laptop troubleshooting is an important operational function which every laptop owner and user should know as it will facilitate in the proper running of the laptop. 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. You yourself can solve and repair several technical snags of your laptop which will save you from laptop technicians. A dead LCD trouble may be due to the failure of video adapter, main-board, a burnt out backlight or bad inverter. Such troubles can be easily solved with the help of laptop troubleshooting manual.
There is no point is replacing a LCD if it has a minor technical problem, it is replaced when blocks of dead and burnt out pixels or physical crack in the glass appears. You might be thinking that laptop troubleshooting differs from company to company but it is not like that, fundamentals are same. If you know laptop troubleshooting, you can address technical problem of any of the laptop like HP Compaq, Toshiba Satellite, or IBM ThinkPad. Although, these laptops are equipped with AMD, an Intel CPU or a PowerPC but they all experience more or less identical technical snags because of affinity in design and structure.
Soldering Supplies
Identification of the snag is the first point in laptop troubleshooting. Suppose, if there is a snag related to power then rectify this by restoring proper power supply. Check LED, power plug and battery in this regard. If you find that all these things are working properly then check the power switch and main-board supply. This is how you can solve your problem related to power supply. If you think that your laptop battery get exhausted soon then through control panel allow the power saving modes. If you want to clean your laptop from dust, then its better to use good quality solder sucker.
If there is a problem of video failure, then your first step should be checking the power supply. If you had heard the sound of your laptop at a point of time but now there is no such sound then this could be indication of it's a power failure from the main-board instead of video failure. If there is any internal disorder of the physical connectors like the detachment of network or modem port then soldering should be done with the help of a quality solder. If you want to check mother board or internal video adapter then connect an external monitor with a regular VGA; if there is no light in the external monitor then you should check the above faults.
Even if your external monitor is working properly then also there could be problem in the video subsystem. If you notice - dead spots or columns or complete row augments gradually on the screen, then it shows that the assembly of LCD in your laptop is poor. If you find that screen glow fluctuates then most probably it is a failure of backlight or inverter. These were some of the highlights of laptop troubleshooting (one may frequently witness such snags) but you will find it useful in number of other ways.
