The digitizer is the component that converts the touch input into electrical signals that are processed by the tablet. If the digitizer is damaged or malfunctioning, it may not register the touch input correctly or at all. The technician can test the digitizer using a diagnostic tool or by replacing it with a known good one. Updating the device drivers, replacing the damaged screen protector, or performing a factory reset are unlikely to fix the issue, as they do not address the hardware problem.

The most likely reason for this error is A. The HDD is malfunctioning.

A bootable device not found error usually indicates that the system cannot access or detect the hard disk that contains the operating system files. This could be due to a physical or logical damage to the hard disk, such as bad sectors, corrupted partitions, or faulty cables. According to the web search results, some possible causes and solutions for this error are:

Hard drive connection issue: Check the cabling and power supply to the hard drive and make sure they are properly connected12.

Corrupt hard drive partitions: Use a Windows installation media to scan and repair the corrupt system files using the System File Checker (SFC) tool1.

Damaged hard drive: Replace the hard drive with a new one and reinstall the operating system2.

Incorrect boot sequence in the BIOS: Enter the BIOS or UEFI settings menu and change the boot order to make sure that the system drive is in the first position13.

Damaged MBR (Master Boot Record): Use a Windows installation media to repair the Windows bootloader using the Diskpart tool1.

Physical cabling issues refer to any problems with the cables or connectors that connect a display to a computer or a power source. Physical cabling issues can cause various symptoms, such as slow to turn on, distorted and discolored images, lines going through the image, and intermittent blank screens. The technician should check the cables and connectors for any damage, looseness, or interference.

The next troubleshooting step that the technician should attempt is to restart the smartphone. Restarting the smartphone can help resolve many common issues, such as battery drain, network utilization, app crashes, or performance slowdowns. Restarting the smartphone can do the following:

Clear the memory and cache of the smartphone, which can free up space and speed up the device.

Close any background apps or processes that may be consuming battery or network resources, such as syncing, updating, or streaming.

Reset the network settings and connections of the smartphone, which can improve the signal strength and quality.

Refresh the operating system and the user interface of the smartphone, which can fix any glitches or errors.

To restart the smartphone, the user can follow these steps:

Press and hold the power button of the smartphone until a menu appears on the screen.

Tap the option that says Restart, Reboot, or Power off and on.

Wait for the smartphone to turn off and then turn on again.

Enter the PIN, password, or pattern to unlock the smartphone.

Check the battery level and the network utilization of the smartphone.

If restarting the smartphone does not solve the problem, the technician may need to try other troubleshooting steps, such as updating the mobile OS, disabling Bluetooth, or connecting the smartphone to a Wi-Fi network. However, restarting the smartphone is usually the first and simplest step to try.
