Short Persian PDF of about 70.4 KB whose title translates as how to test a charging circuit. No device or board is named, so expect a general tutorial rather than a model-specific schematic. Material like this explains checking input voltage, the charging IC, MOSFETs and battery connections with a multimeter or bench power supply. It is useful context for diagnosing charge faults on phones or laptops, but confirm component values against the actual board's schematic before replacing anything.
