- 🧤 Antistatic wrist strap or gloves
- 🪙 Plastic pick for opening latches
- 📦 Container for screws divided by type
Don't neglect organizational issues. Arrange the screws in the order you remove them to avoid confusion during reassembly. Some models HP ProtectSmart The screws are different lengths, and driving a long screw into a short hole can damage the board.
Removing the bottom cover and turning off the power
The process of removing the bottom cover begins with unscrewing the visible screws. Please note that additional fasteners may be hidden under the rubber feet. Carefully pry them off with a sharp object without damaging the adhesive base. After removing all the screws, you need to release the latches around the perimeter of the case.
Use a plastic card, running it along the junction of the cover and the body. You will hear characteristic clicks - this is the locking mechanism. Do not use excessive force to avoid breaking the plastic. Once the lid is free, lift it and set it aside.
⚠️ Attention: When removing the cover, proceed slowly, as there may be hidden cables under it that were not disconnected in advance.
The next critical step is to completely de-energize the system. Find the cable that goes to the built-in battery and carefully disconnect it from the connector on the motherboard. This is a prerequisite for safe operation of components, including the system HP ProtectSmart.
Working with HP ProtectSmart security
System HP ProtectSmart is a unique feature of these devices. It consists of a hard drive with a built-in accelerometer and associated software. When disassembling, it is important to understand that the shock sensor reacts not only to a fall, but also to sudden vibrations due to careless handling of the case.
If you're planning on replacing your hard drive, make sure the new drive also supports security technology or that you're willing to reconfigure the software. In some cases, replacing a drive requires calibrating the system, otherwise it may generate errors or turn off the drive at the slightest movement.
- 🛡️ Check for a sensor on the old disk
- 🔌 Disconnect the disk cable before removing it
- 💾 Save your security driver settings
Pay special attention to securing the hard drive itself. It is often installed in a special tray with dampers that dampen vibrations. Do not overtighten the tray mounting screws to avoid deforming the dampers. This can cause the system to perceive normal laptop operation as a shock.
It is important to note that when replacing the drive with an SSD, a protection system may not be needed since SSDs have no moving parts. However, the software may continue to run in the background if it is not removed.

Removing the hard drive and installing a new one
To remove the hard drive, you need to unscrew the screws securing the metal tray to the case. Usually there are four, but in some models HP one staple is used. After unscrewing the fasteners, carefully pull the tray by the special tongue or plastic handle.
After removing the tray, unscrew the side screws holding the drive itself. Remove the drive and disconnect it from the SATA connector. When installing a new drive, follow the steps in reverse order. Make sure the disc fits snugly and does not wobble in the tray.
⚠️ Attention: Do not touch the gold contacts on the drive connector and motherboard with your fingers to avoid oxidation.
If you are installing an SSD instead of an HDD, check the drive height compatibility. Some thin SSDs may require the use of special spacers or adapters to ensure that the mounting system HP ProtectSmart worked correctly. Otherwise, the disk may move when the laptop moves.
After installing the new drive and connecting the cable, do not forget to secure the tray with screws. Do not over-tighten them to avoid damaging the drive housing. Light pressure is enough.
☑️ Check before assembly
Assembly features and performance testing
Assembling the device begins with installing the bottom cover. Before doing this, check to see if there are any foreign objects, such as screws or pieces of plastic, left inside the case. Carefully align the grooves of the cover with the body and press until characteristic clicks are heard around the perimeter.
After the latches snap into place, tighten all screws. If you removed the battery, connect its cable to the motherboard. Turn on your laptop and check if the operating system boots. Make sure the new system recognizes the drive.
- ✅ Check for HP ProtectSmart drivers
- ✅ Run the hard drive diagnostic utility
- ✅ Make sure the system does not show sensor errors
If the system does not see the disk or issues a warning about sensor damage, the cable may not be connected tightly. You'll have to take the laptop apart again and check the contact. In some cases, reinstallation of security drivers is required.
What to do if the system does not see the hard drive?
If the system does not see the drive, check the connection of the SATA cable. Also try updating the BIOS or reinstalling the disk controller drivers. In rare cases, you may need to reset your BIOS settings.
It is important to test the operation of the security system. Gently tilt the laptop in different directions and make sure that the system responds to changes in position. This will confirm the correct operation of the accelerometer and correct assembly.
Specifications and component compatibility
When choosing replacement components, you need to consider the specifications of your laptop. System HP ProtectSmart works with certain types of interfaces and disk sizes. Below is a table of the main parameters to consider.
