Among the internal hardware of notebook computer, hard disk, optical drive and other components are most likely to fail.According to my experience, two of the three laptops I used could not work properly due to hard disk failure.
When there is a problem with the hard disk of the notebook computer, many people will choose to send it for repair.However, I don't think it is necessary to do this at all, because it is very simple to replace the laptop hard disk by yourself.The following is a method to replace the laptop hard disk, please refer to interested friends.
Step 1: Prepare a new 2.5-inch notebook hard disk
Notebook computers usually use 2.5-inch hard disks, which are the same size as solid state disks and smaller than the hard disks used on desktop computers.If you encounter a laptop hard disk failure, you can purchase a new 2.5-inch laptop hard disk online or in the computer city.In addition, if your notebook supports the SATA3.0 interface, you can also consider replacing it with a solid state disk.
Step 2: Remove the bottom cover of the laptop
To replace the hard disk of the laptop, the biggest difficulty is to remove the body.However, the top back cover of most laptops is relatively easy to remove. Generally, just use a Phillips screwdriver to unscrew the bottom fixing screws, and then open the bottom case to see the internal hard disk.However, some laptops have trouble removing the back cover. For example, Lenovo Z400 and Z500 models need to remove other components such as the keyboard first, which may be slightly more complicated in this case.
Step 3: Replace the laptop hard disk
1. After removing the bottom case of the laptop, we can easily find the internal hard disk.It is usually fixed to the motherboard.First, remove the screws that secure it and take it out of the hard disk interface in parallel. 2. After removing the hard disk, we will find that it is still fixed by a frame.Continue to remove the retaining screws on the frame and remove the hard disk from the frame. 3. Next, we will install the new hard disk into the frame and fix the screws. 4. Finally, reinsert the hard disk into the hard disk interface and fix the screws.This completes the replacement of the hard disk.
The last step is to reinstall the bottom shell of the laptop.In general, replacing the laptop hard disk is very simple, even for beginners.For laptops with complicated disassembly, I suggest non professionals not to forcibly disassemble them, but ask professional technicians for help or send them to repair.
Buy a sata at the insurance point, install the original mechanical hard disk to the optical drive, and install the solid-state hard disk to the original mechanical hard disk
