I have a toshiba C55t-C5300, motherboard model DABLQMB16B0 rev:B. No luck finding the schematic. This chip, marked PU4 consumes around 200 mA when 5v are put in with the bench power supply. Lower voltages do not turn it on. It heats up rather quickly. Markings appear to be 3G=2G and U25 underneath. It has 5 contacts on each side, total of 20. One appears to have a balled up solder joint. No power, no lights at all. DC jack ok.
Further research indicates that DA0BLQMB6E0 is similar board. Quanta BLQ.
Help please identifying it.
