There are so much damage to the laptop , especially the problem of laptop hardware damage . Pretty much difference with the PC that looks much more friendly . In this post I will summarize the problems of the most common laptop hardware and solutions respectively . That means that this article is not final and will end when all these issues been discussed.
Problem # 1. Total dead laptop.
Description of the problem: When you plug the AC adapter into the laptop, no lights turn on at all. When you press the power button, no reaction occurs. Laptop seems completely dead, no sound, no indication of life.
Possible problems: AC adapter fails and the battery is fully discharged. First, test the AC adapter. If it dies, replace the adapter.
DC jack regardless of the motherboard (or DC jack is damaged) and the laptop does not gain power from the AC adapter. In this case the DC jack should be replaced.
Laptop Motherboard damaged. If that happens, most likely not feasible laptop repaired.
Problem # 2. Laptop turns on but the screen is blank.
Description of the problem: the laptop is on, the LED lights on the laptop is on, the cooling fan is working but nothing appears on the screen. The screen is completely black and empty. No images on the screen at all, even very dim picture also does not exist.
Possible problems: This problem can be attributed to a failure of memory. Probably from the memory module failed and the laptop does not turn on because of it. In this case you can try reseating the memory module to ensure proper contact with the slot. You can try removing memory modules one by one and test the laptop with just one memory module installed. You can try replacing the memory module with the new module.
If reseating / replacing a memory module does not help, try to remove the hard drives, DVD drives, modems, wireless card, keyboard, etc ... In other words, disassemble the laptop and installed only minimal equipment and test again. If the laptop still does not turn on, most likely failure
motherboard or processor.
Problem # 3. Laptop turns on and then die again.
Description of the problem:
Laptops turn on without showing any image on the screen. After a few seconds the laptop will shut itself down. Then turns on and off again. It keeps going until we turn off the laptop completely.
Possible problems: Most likely it happened because of some kind of motherboard failure. You can try reseating / replace memory as I described in problem 2. If it does not help, mean  damage the motherboard. In most cases, it is very difficult to replace the motherboard, it's better to buy a new laptop.
Problem # 4. Laptops are very noisy.
Description of the problem: Laptop turns on and everything is working well, he made a few oddities that noise and crackling. Some laptops make noise all the time, other laptops only intermittently.
Possible problems: In most cases this noise coming from the cooling fan or laptop hard drive. You can turn on the laptop, wait until the voice came again, and then listen carefully to the bottom of the laptop. If the laptop is making noise when the cooling fan starts running, most likely damaged. Replace the cooling fan. If the laptop is making noise even when the fan is not spinning, maybe it comes from the hard drive. Back up all personal data from your hard drive as soon as possible, the total damage may occur at any time. Replace the hard drive.
Here is another technique to find out whether the noise coming from the fan or hard drive. Remove the hard drive from the laptop and start the laptop. Wait until warm and the fan starts spinning. If the laptop is still making the same sound even when the hard drive is removed, most likely a faulty fan.
Problem 5. Laptop die or crash when being used.
Problem description:
Laptop up and running properly, but after a while directly hangs or die without any warning. When that happens, the laptop feels hot on the bottom. Also, the cooling fan to work harder than usual.
Possible problems:
Most likely this is a hot issue processor. This happens because the cooling module clogged with dust and the laptop can not "breathe" properly. The laptop is turned off or j
ammed because the processor (CPU) is too hot. Clean the cooling fan and heatsink to fix the problem.
