My 2013 MacBook Air suddenly stopped charging & these guys fixed it within 12 hours! After asking at the Apple store (who quoted me $700), I dropped in to IPD to ask for a second opinion. After quick diagnostics, they suggested it was likely corrosion over SMC chips preventing charging, & quoted $280 to fix it completely within 24 hours. I received a call later that afternoon saying it was fixed & all working fine. Unsure why I haven't found these guys sooner! Will come back & update to 5-stars once my laptop survives another 6 months! Thanks guys!

Approximate cost: $280
