The BYG43 NM-601 board, I can not find a schematic for this model anywhere, if anyone could identify the PD109 and U101 elements on the FWL diode and the 5 foot transistor has the 5AF2W mark in advance, thanks for all your help.
Look for Compal BTUU1 ( NM-A381 Rev: 1.0 from Nov.2014) - rather hard, but look at other Compal solutions starting with NM-Axxx - plus applications of layouts in which the elements are sought
On the NM-A381 Rev: 1.0 board: - IT8386E-192 - TPS51716 - BQ715 - DC-DC GPU / CPU / RAM converters> NCP81172 / NCP81108 / TPS51716 - stby + 5V SYX196C1QNC (case: AR4) from SILERGY - stby 3,3V SYX196C1QNC (case: AR5)
See e.g. in LA-B102P / AIVP1 / AIVP2 LA-C771p rev: 1.0 / LA-B231P * SYX198DQNC _..... see LA-B981P
Important for Lenovo when describing the board: FRU # 5B20K41654 Link
Write in approx. What chip you have this PD109 and transistor. With the description of smd at Lenovo it is a massacre, they take components from brothers from behind the "great wall" ..... and there is different _______________________________
The discussion revolves around the BYG43 NM-601 board used in the Lenovo Yoga 700-14ISK, focusing on identifying components PD109, U101, and the 5AF2W transistor. Users suggest looking for schematics related to similar Compal boards, particularly the NM-A381 Rev: 1.0, which includes various components like IT8386E-192, TPS51716, and BQ715. The BQ24770 system is identified as relevant, with discussions on the battery socket and potential Schottky diode applications. Users share images for reference and seek further clarification on the layout and component markings. Summary generated by the language model.
