        update:after a month client came back same laptop plugged in fan spins a bit then goes off, upon checking voltages main voltages presents except for checking this 2 ics PU200 AND PU201 which is the problem both is pin9 which +3V_PWRGD for pu200 and +5V_PWRGD for PU201.And also notices pin1 of PU200 +3VBS Supposed to have +3v but measured 6.6v and same with pin 1 of PU201 +5VBS supposed to have +5v but measured 8v . anyone could help this please

                Same board, same readings, same problems: did you solve it?

                    It seems that nobody managed to fix this boards when they go bad most of the time, I have the same issues but unfortunately people do not come back to report success or failure.

                        I have this Lenovo laptop under repair with strange behavior, no display at first I thought it has a corrupt bios but now after disassembling it I have doubts, the laptop turns on automatically after inserting the charger without pressing the power button, If I hold down the power button for 8 seconds, it turns off for 1 second but turns on immediately after 1 second, so you can't even turn it off, tested with and without RAM,...

                        Hello guys,

                        I have a shorted MOSFET K8A60DA with the following characteristics:
                        Type Designator: TK8A60DA
                        Marking Code: K8A60DA
                        Type of Transistor: MOSFET
                        Type of Control Channel: N -Channel
                        Maximum Power Dissipation (Pd): 45 W
                        Maximum Drain-Source Voltage |Vds|: 600 V
                        Maximum Gate-Source Voltage |Vgs|: 30 V
                        Maximum Gate-Threshold Voltage |Vgs(th)|: 4 V
                        Maximum Drain Current |Id|: 7.5 A
                        Maximum Junction Temperature (Tj): 150 °C
                        Total Gate Charge (Qg): 20 nC
                        Rise Time (tr): 25 nS
