Laptop Motherboard Repairing

No comments :
When a laptop starting problems in performance or stopped working. If your laptop is in under warranty, there is no problem because laptop’s company will fix the error. But if it crossed the warranty date then its clear mean is that you should go for new laptop because the cost of new mother board equal to the present value of laptop.
Testing and results: firstly check the adapter and then plug in it to laptop and push the start button.
     ·       Adapter is okay but laptop not giving sign of booting means not even a single LED glow.
     ·       The LED is on, you can listen voice of spin of fan, but nothing in the screen display. And after 10 to 15 second HDD working sound also off.
     ·       The LED glow and the fan spin, but after a few movements the LED goes off.
     ·       Display dark and you can listen to a louder sound arriving from laptop computers.
     ·       Laptop just starts and takes a boot and then shut.
Troubleshoot:
Lid closed button: Check the “lid closed” button and try pressing it a frequently. It’s usually a little button near the hinges that is pushed while the lid is shut. Sometimes these buttons get jammed in the “lid closed”. So the outcome is dark screen or non-starting laptop. Also some notebooks have a magnet button that doesn't get jammed. Lots of new companies remove this button.
Test laptop with another adapter: Although not typical, the adapter can able to give required power of mother board even if it has a LED power on that lighting up when you connect it in. Even if you evaluate the outcome volts and it’s OK, the adapter may didn't work and wouldn't provide that volts under fill (typically 3.5A to 6A). You can use a worldwide adapter or go to a separate mechanic and ask them to examine it. If you can arrange a multi meter you can check adapter with it. It gives you clear information about resulting voltage.
