Hello all guys,
I'm checking an Elitebook 8440P which is not turning on but the charging light blinking with blue and orange when i connect the charger.
I thought that it is the problem bad controller so i replaced with new one KBC1098NU. But same, So i changed TPS 51125 and BQ 24740 but all is vain.
When i closely look the voltages on PQ101 Pin Numbers 5,6,7,8 and there are no voltages. But on a working Motherboard there are 19 Volts here. Again when i check PQ 101 Pin # 4, There are 19 Volts but when i check on a working Motherboard there are 8.65 Volts.
Anybody can tell me what should i do?
