How it's done
What our technicians do, what it requires, and how to tell you need it.
When this needs a genuine repair rather than a reset, our technicians start with component-level diagnosis under a microscope — checking power rails, shorted capacitors, and damaged ICs with a multimeter and thermal camera — before any chip-level soldering work begins, since a wrong first guess on a board-level repair can turn a fixable fault into a dead board.
Typical time: 2–24 hours depending on fault complexity
The model
The HP ProDesk 400 G9 is HP's mid-tier business desktop line — sitting below EliteDesk, offering business features at a more accessible price for small/medium businesses.
Don't waste time on booking portals. Reach the engineers directly with Xigox. Bulging or leaking capacitors in Null Bazaar are an extremely common fault on boards older than 5 years — especially after Mumbai's humid monsoon cycles.
