Hardware Components of Laptop

A laptop usually contains the following components, so the repair of it refers to the repair of corresponding parts.

  • CPU: it’s the abbreviation of Central Processing Unit. It’s an important electronic circuitry to carry out the instructions of a computer program. The CPU has been applied to computer since the early 1960s.
  • CPU fan and CPU socket: the former is used for heat dissipation while the latter is a connector on the motherboard that houses and contacts with CPU.
  • Heat sink/heat pipe: they are used to provide air circulation in a compressed space so as to avoid overheating.
  • Battery: it’s the main power source for a laptop. The CMOS battery is used to keep the time, date, hard disk and other configuration settings in the CMOS memory.
  • Speakers: obviously, it is used to create sound, so that you can hear a voice from your laptop.
  • RAM: short for Random-access memory, the RAM means the computer memory that you can access randomly.
  • Hard drive: store videos, audios, documents, pictures, photos, and other sorts of data.
  • Etc.


Among them, the hard drive is the most important component since it stores many significant data. Once you find your laptop hard disk is crashed, you must take actions immediately to restore files.

Laptop Repair Tutorial

Laptop errors can be divided into mainly two categories: hardware issues and software issues.

Hardware Error Repair

The laptop hardware repair contains mainly 2 steps.

Step 1: manufacturer maintenance.

Each laptop is provided with a warranty when you bought it. Once you find a hardware component is damaged or corrupted, you should first consider returning to the factory for repair. As long as the hardware is not broken intentionally and it’s under warranty, the manufacturer will fix it for you.

What to do with a dead hard drive?

I have found that the platter of a brand new hard drive is not 100% flawless when it comes out from manufacturers. This is because the platter is very precise and has a high requirement in the manufacturing environment. Thus, even a speck of dust or a minor collision could lead to a few to hundreds of bad sectors.

Therefore, if a hard drive is dead and it is not caused by human factors (like physical scratch and logical damage during using), users can choose to send their hard drive back to manufactures for maintenance as long as it doesn’t exceed the warranty period. But before users do this, please remember to backup hard drive data if it’s possible.

If the dead hard drive is an external one, the recovery & repair work would be much easier:

Step two: replace the damaged part.

If the laptop drive exceeds the warranty period, you can try to remove the damaged part and replace it with a new one. Under such circumstances, you need a screwdriver, such as Phillips screwdriver and hex screwdriver for taking off the cover so as to replace the broken component.

  1. Remove the screws with the screwdriver.
  2. Take the cover off carefully.
  3. Locate the component inside the laptop and take it out.
  4. Mount a new one into it and put back the screws.
Warning: You shouldn’t try this unless you have much experience; after all, ordinary users tend to make things worse. My advice is to search for laptop repair near me in Google and then send your laptop there for repairing.

Software Error Repair

To fix the software error appeared on your laptop, you should get a laptop diagnostic tool to help you settle down the problems and recover files from the hard drive.

  • The built-in Mac repair tools available for you: Disk Utility, Apple Hardware Test, and OnyX.
  • The built-in Windows repair tools you can use: System Restore, Troubleshooter, Disk Error Checking, System File Checker, factory reset, Windows Defender (anti-malware tool). These Windows repair tools also work for USB drives.

Here, I’ll mainly introduce the methods for using the Windows repair tool to diagnose and fix disk-related problems in Windows 10.

One: System Restore.

System Restore is a useful tool contain in Windows. It can help you cancel the changes and restore your system to the previous state when problems didn’t occur (the premise is you have enabled the feature under Configure System Restore).

As the name suggests, this tool will check the disk and find errors on it. You can get this tool to work in two different ways.

Way 1: check disk in File Explorer.

  2. Locate the drive which needs to be repaired.
  3. Right click on the drive and choose Properties from the context menu.

  5. Find the Error checking section and click on the Check button.
  6. If the system detects no error, it will show you a window saying You don’t need to scan this drive (you can still choose to Scan drive); if any errors are detected, you’ll be asked to check the drive so just click to scan.
  7. Wait for the scanning to finish.
  8. Follow the instructions given by the system.


Way 2: run CHKDSK in Command Prompt.

  1. Click the Start button from the lower-left corner of the laptop screen.
  2. Scroll down to find Windows System folder and expand it.
  3. Right click on Command Prompt.

  6. Type CHKDSK *: /f into the Administrator: Command Prompt window (* stands for the drive letter of target drive).

Tip: By the way, some users complained that the CHKDSK command has deleted some of their useful files. If that happens to you, don’t panic since this post will guide you to solve the problem quickly.

All in all, it’s very useful to run the error checking tool when you have corrupted file or directory or when the laptop says your operating system is not found.

  1. It fixes soft errors by rewriting the faulty data.
  2. It resolves hard errors by marking the certain section of your disk as being damaged, so it won’t be called for future use.

In addition, there’s a feature named Security and Maintenance, which is able to help monitor your Drive status.

Drive status

Four: System File Checker.

The SFC tool is built in all modern versions of Windows and it is mainly used to repair corrupted system files.

  2. Type sfc /scannow and press Enter on the keyboard.
  3. Wait for the scan. (This command will scan the protected system files; if any corrupted files are found, it will replace them with a cached copy located in %WinDir%\System32\dllcache folder.)


Five: Windows Defender.

Windows Defender is the anti-malware component built-in Microsoft Windows. It is able to scan your drive for malware, viruses, and security threats so as to protect the laptop. (How to recover files that have been deleted by virus?)

Manufacturer maintenance vs data recovery agency service:

  • One of the most serious deficiencies of manufacturer maintenance is that all data saved in the hard drive may be lost since low-level format would be performed to hard disk with parameter error or manufacturers will send users a new hard disk if the previous one has quality issue.
  • Yet, the obvious deficiencies of getting data recovery company to help you are high cost and privacy leakage possibility; you need to pay much money for the data recovery and your confidential data may be leaked out. (Curious about the data recovery prices?)
