Diagnosing the Problem
Laptops are very sensitive and the hardware problem could be really weird. It is important to diagnose or locate the real problem. The basic repair work would consist of removing malware or any other spyware, apart from getting a check on antivirus and so on. However, the more difficult problems come up when the laptop doesn?t get powered or just runs without any display on the screen. Problems of overheating and insufficient cooling also are part of hardware problems. Sometimes, the LCD screen is faulty or there is something wrong with the circuit powering the screen. This might even require replacement of the screen.
Sometimes the booting takes place normally and the welcome sound is also heard, but there is no display on the screen. The notebook has to be disassembled to locate the problem. Sometimes, the screen itself becomes defective, with vertical bands and lines that appear on it. In other cases, half the screen works while the other half remains blank or the output is blurred and shows different patterns. These are to do with problems in the LCD panel, the connectors or the
system board. Sometimes, the LCD panel could have gone completely defective and there is no way of fixing it ? in this case, it needs a replacement screen.
Hardware problems
Other hardware problems could be to do with the power connector, such as the DC power jack getting damaged. The power jack is quite weak and sometimes sparks and heating will occur that can burn a hole in the motherboard. There are also several other signs for such problems, such as the battery not charging properly or it continues to remain at half charge even if you are using the power adapter. Sometimes, the laptop shuts down suddenly and looses power. This could be because the motherboard has started to burn and the DC power Jack may have to be changed.
The problem has to be located first and then one must start looking to fix it. Before giving it for any hardware repair you have to provide information about the exact notebook, the manufacturer, the model and specifications and other details that you can think of, including the kind of activities that you have been involved in.? A lot of practice and patience is required to repair such problems.
