Probus Palm Comfort A744 Silent Wireless Keyboard and Mouse

Complete Maintenance for Quiet, Low-Profile Workspace Peripherals

A premium office setup relies on smooth, quiet, and ergonomically sound input devices. Over months of heavy typing, even robust hardware can develop sticky keycaps, unresponsive switches, or signal dropouts. IT Repair Hub provides professional, component-level motherboard repairs, key contact cleaning, and trace rebuilding. Keeping your Silent Wireless Keyboard and Mouse combo properly calibrated is essential to maintain a quiet, distraction-free environment under 22dB.

Most membrane keyboards use layered flexible circuits. When liquids, dust, or debris slip underneath the keycaps, they block the electrical contacts and cause specific keys to stop registering. If your Silent Wireless Keyboard and Mouse setup starts dropping keystrokes, our laboratory technicians can completely disassemble the chassis, clean the conductive trace layers, and realign the keycaps. For deeper system integration issues or laptop USB port failures, you can check out our dedicated laptop services link to resolve any computer-side hardware conflicts.

Chocolate Keycap Realignment and Palm Comfort Maintenance

The Probus A744 is highly regarded for its integrated wrist rest and low-profile chocolate keys. If a key begins to feel stiff or loses its soft-touch feedback, the delicate scissor-like guide rails or silicone domes beneath the cap may be misaligned or torn. We carefully service individual keycap mechanisms on your Silent Wireless Keyboard and Mouse to restore that original, effortless typing experience. This careful upkeep ensures your keyboard can easily reach its design rating of 10 million keystrokes.

In addition, we handle aesthetic wear. We thoroughly clean the laser-engraved key legends of oils and dirt, preventing key fading and ensuring the keyboard looks and performs like new.

6D Multi-Button Mouse Micro-Switch Restoration

The accompanying 6D wireless mouse features an ergonomic shell, a multi-button layout, and 3 adjustable DPI modes topping out at 1200 DPI. Intensive daily work can wear out the internal clicks, causing double-clicking issues or missed inputs. During our repair process, we desolder the worn-out switches on your Silent Wireless Keyboard and Mouse and install high-grade, silent tactile micro-switches that keep the mouse click noise well under 22dB.

We also service the scroll wheel and optical lens. If scrolling becomes jumpy or the cursor drifts across your screen, we deep-clean the optical tracking lens and rebuild the mechanical scroll encoder to ensure smooth, pixel-perfect accuracy.

2.4GHz RF Transmitter Diagnostic and Battery Optimization

If your devices keep losing connection to the USB dongle, it is usually due to a cracked USB connector, cold solder joints, or a failing 2.4GHz antenna. Our hardware repair services trace the RF signal path on the Silent Wireless Keyboard and Mouse circuit boards to resolve range drops and lag. We also clean the battery contacts and repair voltage leaks on the motherboard to ensure the keyboard achieves its 12-month and the mouse its 6-month battery lifespan.
