Re: Lenovo v330-15kb : no power

up

Hello,

I'm working on a Lenovo v330-15kb motherboar, no power ni light. I checked the voltages and everything looks ok on S5 phase but can't go any further. Initially the problem came from the bios, bad update. I reflashed it back with a ch341 but still nothing. The battery was discharged (less than 2V, 2 cells). I charged it directly and the output voltage is around 8V. The sio_slp_s3 and sio_slp_s0 signals remain active and the prochot and vr_hot signals are also active. I sigh the battery not to communicate with the motherboard because fault flag due the undervoltage.

Hello,

I'm here to ask your help about a laptop repair, 6050a2725001-mb-a01. From what I could see, there was liquid damage. As you can see from the pictures, there is a whole power line burned because of a short in liquid.

I assume that the IC that burned is a DCDC converter. When I googled the reference, there are no results. I find several circuits of the same composition on the motherboard but with different reference as on the images. I also removed one of the intact IC and the burned IC to better see the original condition.

From what I could...
