How to Reflow a Laptop Motherboard

This article describes a reflow procedure that can be performed at home in a conventional household oven for a common laptop motherboard repair of the broken graphics chip.

What is a Reflow?

The term ‘reflow’ describes a process of briefly melting (reflowing) the solder on an electrical circuit board, in this case a laptop motherboard.

Why would you perform a Reflow on a laptop motherboard?

The solder used in laptop motherboards tends to degrade over time, becoming brittle and weak. It can change from being a solid block of solder into more of a honeycomb structure. This weaker solder joint can fracture causing tiny broken connections in the circuit, invisible to the naked eye. The idea behind performing a reflow is that it melts the solder, allowing it to form a solid block again and joining up the electrical circuit. Continue reading


CrystalDiskInfo is a great little free tool for checking the general health of your hard drive.  It works by reading the S.M.A.R.T. data off your hard disk and displays it in a simple graphical format.  It can work with internal or external hard disks, with either IDE (ATA/PATA) or SATA connectors, and it even works for hard disks plugged in via USB.

Each of the S.M.A.R.T. parameters has a threshold, beyond which it could indicate a drive starting to fail.  If CrystalDiskInfo determines that any parameter is showing potential problems, it will highlight that row in the results table. Continue reading

Why you should shutdown your computer and not just press the off button

This article explains why it is important to shutdown your computer properly.

In our repair shop, we are sometimes asked by customers if there is any harm in shutting down their computer by just pressing the power button for a few seconds, rather than going through the Windows shutdown procedure.

As far as the customer in concerned, the end result appears to be the same, the computer shuts down. In fact, from their point of view, holding the power button for a few seconds appears to shut down the computer immediately, whereas a proper Windows shutdown takes maybe 20 to 30 seconds. So is it a good idea to do this?

To get straight to the point, it is a very, very bad idea to shutdown your computer by holding the power button. Continue reading

How to Create a System Restore point in Windows 7

After installing and setting up a fresh copy of Windows, there are times when you check the Device Manager and you see the little yellow exclamation point meaning a driver hasn’t been installed for a device.

If the driver isn’t on a driver disk, and maybe you don’t have a copy of the driver because your original hard disk was broken – what do you do? The device just shows up as unknown modem, or unknown media device or something similar.

What you can do is check the properties of the device, find out its signature and look it up on a great little website Continue reading
