Technicians connected remotely via TeamViewer, found the graphics adapter disabled, re-enabled the device and installed an updated graphics driver. External monitor and projector output were verified after the driver/device change and the problem was resolved.

After contacting the user and coordinating a session, the workstation was restarted; the RZ616 adapter and the network connection returned to normal following the reboot and the user regained network access without further intervention recorded.

Multiple, distinct failure patterns were observed and recorded in the corpus. For Teams-related full desktop freezes, interactivity was restored when the workstation was switched to use the docking station (moving displays/peripherals to the dock), and the desktop recovered. For Dell systems that exhibited GPU/taskbar freezes alongside unexpected BIOS/firmware activity, Dell Diagnostics ran and reported all tests passed (Result Code 2000-0000 | Validation Code 94055); SupportAssist OS Recovery attempts stalled in at least one case and the incident record documented BIOS activity and diagnostics without a single software-only remediation. For intermittent no-power/extended-boot cases on new Dell hardware, the tickets recorded that applying pending firmware and driver updates via Dell Command Update and allowing extra time for large updates to complete addressed some occurrences; when updates did not resolve the problem, systems were escalated for reset/reimage. For performance-related freezes, a Dell workstation consistently showed ~88% RAM use during graphics work and with >20 browser tabs; a replacement Precision exhibited the same high utilization, crash dumps could not be opened, and the condition remained unresolved in the record. In at least one simple workstation outage, a reboot/power-cycle returned the system to normal operation.

Serial numbers were collected for Jamf verification and an on-site staff member successfully logged into the affected iMacs and then logged out. After the staff sign-out, a student was able to log in and the Macs returned to normal operation; the situation was monitored until colleagues on site confirmed the issue was resolved.

Procurement and deployment work was completed through central vendor/order channels and coordinated on-site actions. Orders and purchase approvals were placed and tracked (examples included institutional POs and vendor orders); carrier confirmations and device/order IDs were recorded and used to trace deliveries. Missing or incomplete shipments were re-sent when required. Hardware was consolidated from available inventory when needed and transported to target sites. On-site work included physical assembly of iMacs and workstations, mounting/connecting monitors (including dual-monitor setups where requested), connecting power and network cabling, and bringing lab equipment online (for example, 3D printers were connected to the network). Deployments included peripheral hookups (keyboards, mice, power strips), accessory items (mounting locks), returns/collection of surplus devices (laptops and phones) during rollouts, and basic functional tests (power/boot, network connectivity, and peripheral checks). Remaining post-deployment actions were tracked where necessary (for example, a pending Adobe Creative Cloud install on one iMac). All delivery, assembly and follow-up activities were documented in task/SubTask records and asset inventory references were noted for traceability.

Physical infrastructure blockers and inventory gaps were resolved case-by-case. Missing or inaccessible power was addressed by installing required outlets and scheduling builds after desk assembly windows; where full furniture was absent, partial installations were completed for available desks. Missing or mislocated machines were found, shipped, or reallocated: a missing iMac was shipped to the Magdeburg Medienlabor, assembled on-site, secured and updated to the latest macOS, and Excel inventory lists were updated with device details and serial numbers. Learning Area and StudyPC shortages were handled by locating available units (including one reused StudyPC) and installing them (connections recorded, e.g., to network outlet P.3); unlocated items and printers were logged as missing. Remote-support readiness was established by adding Learning Area PCs/iMacs to the TeamViewer host list with recorded TeamViewer IDs. Physical-security impediments were removed when necessary (a cut Kensington lock was removed to allow setup). Workstations requiring parity with existing desks were assembled and tested (for example, dual-monitor setups installed in Room 223). Missing replacements were noted in inventory records when no on-site substitute was available.

Affected PCs recovered after a hardware-level power cycle/reset. Technicians performed a physical hardware reset/power cycle of the device; in one case the reset was triggered by using a paperclip to press the case reset pin/button. After the hardware reset the machines completed POST and booted into the OS normally and functionality was verified.

The affected systems were rebuilt to the standard corporate image for Office 2.29. The rebuilds were completed and the task was closed; no additional post-deployment verification details were documented in the ticket.
