Acer Predator Helios DC Jack Repair in Hyderabad

Acer Predator Helios won’t charge unless the cable is held at a specific angle? That’s the DC jack — either solder cracks on the barrel (older barrel-jack models) or a worn USB-C port (newer USB-C PD models). For barrel-jack Acer Predator Helios variants we resolder the jack at component level. For USB-C variants we replace the entire USB-C daughter board or the soldered port on the motherboard. Doorstep diagnosis included — we’ll tell you which it is before quoting.

The Acer Predator Helios uses a proprietary 330 W or 230 W barrel-jack (hybrid charging) barrel connector rated for 330 W continuous. The jack PCB pad traces must handle 15 A+ current; solder joint fatigue from thermal cycling causes micro-cracks in the trace, first showing as intermittent charging (the laptop powers on adapter but doesn’t charge the battery). Some Predator Helios 16/18 configs also accept USB‑C PD for slower charging — the USB‑C port wearing out is often misdiagnosed as the barrel jack failing.

We test both the barrel jack and USB‑C ports with a power meter before opening. Barrel jack re-soldering done with high-current solder and mechanical epoxy reinforcement on the PCB pad. PredatorSense charging graph monitored post-repair to confirm both AC input and battery charge status are correct. 30-day warranty; ₹149 doorstep.
