LAPTOP TROUBLESHOOTING
In a Laptop Troubleshooting the problem accurately is the first step while repairing a laptop. For example, when a laptop does not function people may rush to change its battery, but the problem may be a bad connector on the cord of power or a frayed wire which could be fixed with electric tape or a solder. In the same manner a “dead” LCD screen may be a video adapter failure, a mainboard , a burnt out backlight or a bad inverter. The need for LCD replacing occurs when blocks of dead pixels or a physical crack in the glass exist. In the same way there is very little distinction between troubleshooting a HP Compaq, Toshiba Satellite, or IBM ThinkPad. Even though these laptops models uses an AMD, an Intel CPU or a PowerPC the basic designs are the same. Due to wear and tear, overheating or occasional run of bad components they suffer almost similar failures.
Identifying the problem is the first step of Laptop Troubleshooting. If the problem is related to power, (whether question of the laptop not turning on or battery) first step should be related to establishing power to the laptop. You should check the LED and the power plug, next check is the battery. If battery is not the issue then it could be a switch failure. More or so it could also be mainboard failure, for this you need to test with required equipments. If your battery is running down too fast, access through Control Panel and enable the aggressive power saving modes in software.
Again, if there is complete video failure, first of all check the status of the power. If you were constantly hearing fan of your laptop and now it isn’t that means it’s a mainboard or power failure not a video failure. Next step in troubleshooting is to connect an external monitor with a standard VGA connector, if your laptop does not light up the external monitor means either the internal video adapter or the motherboard has failed. Your laptop video subsystem could be failure if the external monitor works fine. On the other hand, if the number of dead spots or columns or whole row increases slowly on the screen, it indicates that the assembly of actual LCD is bad. In the same way if screen brightness flicker it is probably failure of backlight or inverter.
Sometimes laptops are infected by inside disorder of the physical connectors, such as network or modem port may be detached within the case or the breaking of the power connector solder joint of the board. Such problem is very critical because here you need to open up the body of the notebook for soldering. Be careful to use a decent solder sucker for quick clean up.
