IBM ThinkPad Repair

In this guide, we will go through the steps on how to identify IBM ThinkPad faults and replace faulty parts or recover a system.

ThinkPads are pretty interesting machines. If you could see the motherboard you will notice that everything is so packed in such a small space. Due to the small space and almost insufficient ventilation, some of the ThinkPad models tend to get overheated. Such overheating can cause hard disk or motherboard faults. So we don’t suggest keeping ThinkPads on your bed for long spells.
 
IBM ThinkPads have the same systems as every other laptop available in the market. To perform ThinkPad diagnostics, we can use widely available tools like UBCD4WIN, Memtest, UBCD and others. Just a small disadvantage of these tools is that they must be burned on a CD before using them. So you need a working laptop or desktop computer to do this.

To perform IBM ThinkPad diagnostics, we will use a tool named Memtest, which will test its memory. This is a bootable CD which can be downloaded from here and burned. So the first step is to make ThinkPad boot from a CD. We will go to BIOS and it boot from a CD/DVD drive.

To access BIOS, simply press F2 just after you press power button.
This image shows Memtest in operation. The test progress can be seen on top at the right side.

If the memory is faulty, the program will display a message in red.

In case the RAM memory module is faulty, it must be replaced to bring the ThinkPad to normal functionality.

If the memory is good, we can go to the next step where we will test hard drive. To test the hard drive, we will use UBCD4WIN. As mentioned earlier, it needs to be compiled and burned to a CD. Now we are making our ThinkPad to boot from a CD and starting UBCD4WIN. THE UBCD4WIN BUILDER can be downloaded from here. Let’s start the software application now.

First of all, we click on HDTune. Then, we click on the Surface Scan tab. It will show a user interface like this. You don't need to do any changes here; just press the Start button and let the program run for about two hours. You will see the working progress on the screen.

After the program finishes, just check the bad sector number, which is displayed in percentage.  If it is 0%, then the hard drive is good. If the percentage is more than 0 and even if just one red dot is present on the screen, it means the hard drive has a bad sector and the best thing to do now is to replace the hard disk with another one.

Another common faulty part in IBM ThinkPads can be the CD or DVD drive.
