Acer Nitro 7 DC Jack Repair in Hyderabad

Acer Nitro 7 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 Nitro 7 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 Nitro 7 uses a 180 W barrel-jack or USB‑C PD 140 W input. The barrel connector is through-hole soldered on the motherboard. Heavy adapter cables (the 180 W brick is large) lever constant mechanical stress onto the solder joints, especially when the laptop is used on a desk with the adapter plugged at an angle. The first symptom is the laptop powering off when the cable is nudged; NitroSense may show the power source toggling between AC and battery rapidly.

We test the jack with a multimeter under light cable movement to confirm it’s the jack and not the adapter cable. Re-soldering done with lead-free high-temp compound; mechanical epoxy bridge applied between the jack flange and PCB. NitroSense power input stable at 180 W post-repair with cable stress test. 30-day warranty; ₹149 doorstep.
