Laptop Motherboard Repair is that unless you have some of the latest diagnostic equipment, ESD setup workshop, an array of tools, digital multi meters,a test jig and an oscilloscope then don’t think you can narrow down your fault diagnosis to the exact component that is causing your laptop to misbehave nobody has that much time.
If you log a call for your Acer laptop which is in warranty, the technician will turn up (for onsite warranty ) with a fist full of spare parts. He will take a quick look at the machine, keeping in mind they already have a fault description and have narrowed it down prior to turning up. After looking at the machine and verifying it has a fault they will basically gut the machine and rebuild it with new internal parts. I have seen this same technique carried out by IBM, HP/Compaq, Acer and I assume most others would do the same. This excludes Toshiba who have a different system. Here are some things you can do to isolate what sort of problem you have, you may think you'll have to undertake some sort of laptop motherboard repair but quite often the motherboard gets blamed for a fault that may be somewhere else in your machine. Look closely at the symptoms, determine when the fault occurs (unless it’s constant) and try and pinpoint the function that is failing.
Whenever a problem is arises with a motherboard, one should not take the risk of repairing it themselves since if it is not done properly it can lead to irreparable damage to the entire laptop. It is usually safe to approach a dealer of a laptop for the repair of its motherboard. They have technicians who have an expertise in dealing with laptop motherboard problems and can make the right diagnosis and carry out repairs.
One can approach them to repair their motherboard, but a few things should be kept in mind. The most important is to know their experience in repairing laptop motherboards. Let them not convince and fool you by saying that they have repaired many PC motherboards since laptops and PCs are a different thing all together.
