The technician failed to properly diagnose the issue by not establishing a theory of probable cause. Instead of investigating why the network drives were accessible wirelessly but not when docked, the technician assumed a faulty network card and ordered a new laptop. Proper troubleshooting involves developing a theory of what might be causing the problem, based on the symptoms and available information, and then testing that theory. In this case, the issue could have been related to docking station settings, network configurations, or hardware issues specific to the docking connection.

References: This answer is grounded in standard troubleshooting methodologies, which emphasize the importance of logically deducing the most likely cause of a problem before proceeding with more drastic measures such as replacing hardware.

If a user consistently receives an error requesting A4 paper for print jobs, and this issue is isolated to a single user, it's likely that the user's printer settings are configured incorrectly for A4 paper size instead of the standard letter size used in the office. Adjusting the printer defaults in the Control Panel on the user's computer to use letter-sized paper should resolve the issue without needing to reinstall drivers, switch printers, or require the user to check page size for every job.

Secure Shell (SSH) is a protocol used to securely access and manage devices over a network. It provides a secure channel over an unsecured network in a client-server architecture, enabling technicians to perform troubleshooting and management tasks remotely with encryption to ensure the security of the data transmitted. FTP and TFTP are used for file transfers and do not inherently provide the same level of security or direct device management capabilities. RDP is used for remote desktop connections but is not as universally applicable for various devices as SSH.

Upgrading a power supply to add a GPU typically requires more wattage to accommodate the additional power demands. Although the current power supply is 380W, adding a GPU with a six-pin power connector suggests a mid-range graphics card, which would likely need a total system power supply in the range of 450W to ensure adequate power for all components, providing a good balance between capacity and safety margins.
