SMK 2 Tambusai NORTH STATEThere are very much damage to the laptop, especially the problem of laptop hardware malfunction. 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 solution respectively. That means that this article is not final and will end when all these issues been discussed.
AC adapter fails and the battery is fully discharged. First of all, test the AC adapter. If it dies, replace the adapter.
DC jack regardless of the motherboard (or DC jack damaged) and the laptop does not obtain electrical power from the AC adapter. In this case the DC jack should be replaced.
Laptop Motherboard damaged. If that happens, most likely unfit laptop repaired.Problem # 2. Laptop turns on but the screen is blank.Description of the problem: the laptop is on, the LED light on the laptop is on, the cooling fan works but nothing appears on the screen. The screen is completely black and empty. No images on the screen at all, even very dim picture does not exist.Possible problems:
This problem can be attributed to a failure of memory. Perhaps from the memory module to fail and the laptop does not turn 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 the memory module does not help, try to remove the hard drive, DVD drive, modem, wireless card, keyboard, etc ... In other words, loading and attached laptops and only minimal equipment and test again. If the laptop still does not turn, likely failuremotherboard or processor.Problem # 3. Laptop lights up and then die again.Description of the problem:Laptop lit without showing any image on the screen. After a few seconds the laptop will die by itself. Then turns on and off again. This continues to happen until we turn off the laptop completely.Possible problems:Most likely it happened because of some kind of a motherboard failure. You can try reseating / replacing the memory as I described in 2. If the problem does not help, then  damage to the motherboard. In most cases, it is very difficult to replace the motherboard, it is better to buy a new laptop.Problem # 4. Laptops are very noisy.Description of the problem:Laptop is on and everything is working well, he made some peculiarities, namely noise and crackling. Some laptops are making noise at any time, other laptops only intermittently.Possible problems:In most cases this noise coming from the cooling fan or hard drive of the laptop. You can activate the laptop, wait until the voice came again, and then listen carefully to the bottom of the laptop. If the laptop is to make noise when the cooling fan starts running, it is likely damaged. Replace the cooling fan. If the laptop is to make the sound even when the fan is not spinning, maybe it comes from the hard drive. Back up all personal data from the hard drive as soon as possible, the total damage may occur at any time. Replace the hard drive.Here are other techniques to find out whether the noise coming from the fan or hard drive. Remove the hard drive of 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 the fan is broken.Problem 5. Laptop die or crash when being used.Problem description:Laptop is up and running properly, but after a while immediately hang 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 cooling module clogged with dust and the laptop can not "breathe" properly. The laptop is turned off or jammed because of the processor (CPU) is too hot. Clean the cooling fan and heatsink to fix the problem.Problem # 6. Laptop battery is not charged.Description of the problem:Laptop batteries are not charged properly. There are two possibilities; not at all or after you adjust the position of the AC adapter plug in the power connector on the laptop.Possible problems:
Damage to the battery. If the battery is completely not filled at all, try using the first battery alone. If it does not help, remove the battery and try running the laptop from the AC adapter only. If the laptop runs fine from the AC adapter but does not charge the battery at all, most likely the battery is damaged or motherboard problem. Try replacing the battery first.
Remove the DC power connector. If the battery stops charging once you adjust the position at the end of the AC adapter connector, DC jack means problematic.Problem # 7. The screen went dark while the laptop is running.Ddeskripsi problem:Laptops start correctly, but after a while the screen light off. Image still appears on the screen but is very dark. In some cases the display light never start but you can still see a very faint image on the screen. In all cases the laptop video seems to be fine if you use an external monitor or TV.Possible problems:Most likely it is both the inverter screen or screen backlight lamp (CCFL) is damaged. Both are very similar if damaged and cause a dim screen light. To trobuleshoot types of failures effectively, you need a few parts: a new job or a good inverter backlight lamp is still well known.Problem # 8. Laptops have a strange or chaotic picture on the screen.Description of the problem:Laptop flame correctly but the screen shows a picture of the bad or garbled.Possible problems:
Graphics card failure. First of all, test your laptop with an image output on an external monitor. If you see the same problem on the external display, most likely this is the failure of the graphics card.
If the problem only appears on the laptop screen, can be associated with one of the following: a bad connection between the video cable and the motherboard or LCD screens or video cable failed or failing LCD screen.Problem # 9. Some laptop keyboard keys stopped working.Description of the problem:Laptop lights up and running properly but some keyboard keys did not work at all or character typo.Possible problems:Most likely some keyboard keys fail. Laptop keyboard can not be repaired. If some keys stopped working, you have to replace the keyboard.Problem # 10.
