Gave to Acer service center

✅ Internal cleaning

✅ Thermal paste replacement

❌ They said charger is fine — but only did a 2-second test

✅No port damage found

✔️ Software/Settings

Clean reinstallation of NVIDIA driver (DDU method)

Verified RAM/HDD usage, system load normal

Power plans tested: Balanced, High Performance (via NitroSense)

SFC scan: No corrupted files

BIOS untouched (no undervolt or XMP)

OS not reinstalled (ruled out as unnecessary)

Battery health confirmed good via battery-report.html

---

❓ What I Need Help With

I want to confirm:

1. Is the adapter (charger brick) the likely point of failure?

2. Could this be something on the laptop’s power delivery system (DC-in port, power IC)?

3. Would upgrading to a 180W Acer-compatible charger improve stability?

4. Anyone else experienced this and solved it?

---

🔧 Additional Notes

Charger is standard barrel tip (5.5×1.7 mm)

Looking to buy 180W 19.5V 9.23A variant if recommended

I want to confirm before spending ₹2,000–₹6,000

Trying to avoid unnecessary board replacements

---

✅ TL;DR

Charger randomly cuts off during load

Brick gets hot, replugging resumes charging

Behavior repeats in cycles (20–60 mins)

Service helped a bit, but didn’t solve

Likely charger fault, but seeking confirmation before I replace it

Thanks in advance to anyone who can confirm or share similar experience 🙏

    Hi Sanjay,

    Thanks for the detailed breakdown — you’ve clearly put in a lot of effort. That said, a few key points might help clarify what’s going on and guide your next steps:

    🔍 1. SFC Without DISM Is Incomplete

    Running sfc /scannow without first refreshing the system image using DISM means you're validating against a potentially corrupted or outdated source. To properly check system integrity, use this sequence:

    DISM /Online /Cleanup-Image /RestoreHealthSFC /scannow

    This ensures SFC has a clean reference image to compare against.

    🔌 2. Adapter Heating Is Normal During Fast Charging

    All adapters heat up under load — especially during fast charging or gaming. It’s not necessarily a sign of failure. What matters is whether the heat exceeds safe thresholds or causes shutdowns.

    If your battery is not fully charged, the adapter works harder to power both the system and the battery. Keeping the battery at 100% before heavy use helps reduce strain and stabilize power delivery.

    🔋 3. Bigger Adapter ≠ Guaranteed Fix

    Upgrading to a 180W adapter won’t solve the issue if:

    • The DC-in port, power IC, or battery controller is throttling due to age or heat.
    • The BIOS has outdated power logic.
    • NitroSense or Acer Care Center (ACC) is limiting battery charge or interfering with calibration.

    If you’re using features like Battery Optimization, Calibration, or 80% charge limiting, try disabling them. These can cause erratic charging behavior, especially on aging batteries.

    📊 4. What You Should Share Next

    To help the community assist you better:

    • Post the actual battery report (battery-report.html) — especially the Design Capacity vs Full Charge Capacity.
    • Share your exact Nitro 5 model (e.g., AN515-XX), BIOS version and if you have Windows11 24H2 or 23H2 OS installed
    • Confirm whether the system is using RAID/Optane or AHCI in BIOS.

    This info will help determine whether the issue is adapter-related, battery-related, or something deeper in the power delivery system.

    Let us know once you’ve got those details — we’ll be happy to dig deeper with you!
