Sometimes **the orange LED did not light-up** when the power adapter was plugged; sometimes a crazy loop of messages //charger plugged// - //charger unplugged// begun, which can result in phone crash. Sometimes, when the phone was plugged for the nightly charge, the orange LED turned on, but the morning after the phone was completely discharged ad the LED was off.

Clean the flux with a needle, **cotton swab and alcohol**; inspect closely to avoid short-circuits. | ||
