Recently my t7 went from 70% to 63% on overnight charge. Subsequently went to zero. Upon removing and testing the battery it was 3.48 volts. With charger connected it turned on, but then no more. Later it turned on, but only for a couple of minutes. Have you experienced this problem before? Would like to repair if possible, or at least find a way to backup data.
