HP Envy x360 15 — Fan Noise Fix

“My HP Envy x360 15 fan was unbearably loud during video calls. Xigox Santacruz replaced the worn-out bearing fan with a genuine part and applied fresh thermal paste. Whisper quiet now even under load. Very satisfied.”
M Meera Pillai Santacruz · 6 Jul 2024 11

HP EliteBook 840 G10 — Data Recovery Service

“My HP EliteBook 840 G10 hard drive started making clicking noises and then completely stopped being detected by the BIOS. I had five years worth of important work documents, family photographs, and client project files stored on it with no recent backup. Xigox Santacruz team used professional clean-room recovery techniques to carefully extract the data from the damaged platters. They managed to recover ninety-eight percent of all files including ones I had forgotten existed. The entire recovery took around forty-eight hours and they kept me updated via WhatsApp throughout the process. They also helped me set up an automated cloud backup system to prevent this nightmare from ever happening again and upgraded me to a fast solid state drive. Extraordinary data recovery service — I have already recommended Xigox to three of my colleagues.”

Before any work begins, you receive a written cost estimate. Our ₹350 inspection fee is refunded if you proceed with the repair.

How it's done

How We Perform Laptop Boot Loop Fix

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

1 How It's Performed

For this specific fault, we determine first whether the system is failing before the OS even loads (pointing to hardware — RAM, drive, motherboard) or fails during Windows/macOS startup itself (pointing to a software/OS corruption cause) — this single distinction decides the entire repair path.

Typical time: 30–90 minutes

2 What This Requires

  • A clear read on exactly where in the boot sequence the failure happens (before OS load vs. during it), which changes the entire diagnostic path.
  • A backup of accessible data before attempting any boot-repair step that could risk further data loss.

3 When You Need This

  • The device powers on (fans, lights) but never reaches the OS login/desktop.
  • It's stuck on a manufacturer logo, spinning indicator, or repeated restart loop.
  • An error message about a missing or corrupted boot device/operating system appears.
