How it's done

How We Perform Laptop & Computer Power Button Not Working Repair

What our technicians do, what it requires, and how to tell you need it.

1 How It's Performed

For this specific fault, our technicians test for charging while gently flexing the cable at the port (a quick way to reveal a loose internal connection), then open the chassis to inspect and repair or replace the jack itself, reinforcing the solder joints to the motherboard where that was the original failure point.

Typical time: 30–45 minutes

2 What This Requires

  • Reinforced soldering at the board connection point specifically, since the original failure is very often a cracked solder joint from repeated cable flexing, not the port itself.

3 When You Need This

  • Charging only works at a specific cable angle, or stops if the cable is touched or moved slightly.
  • The charging light doesn't come on at all despite trying a known-good charger.
  • The port feels loose, wobbly, or visibly bent compared to when it was new.

Intel NUC 13 Pro — Desktop PC Troubleshooting

“Our office Intel NUC 13 Pro started making a loud buzzing noise from the rear and the system would intermittently freeze completely, requiring a hard power reset which was not only frustrating but risked corrupting our important financial spreadsheets. The Xigox Bhayandar technician disassembled the desktop and found the CPU cooler fan bearing had failed completely and the thermal paste had dried out, causing the processor to thermal throttle severely. They replaced the stock cooler with a much quieter and more efficient aftermarket unit, applied premium thermal compound, cleaned all dust from the case and components, replaced the CMOS battery which was also dead, and updated the BIOS to the latest stable version. The computer now runs whisper-quiet even under full load and is noticeably faster since the CPU is no longer throttling. Tremendous PC repair work — Every person I have sent to Xigox has come back thanking me.”
