Ram regulator misbehaving DDR3 VTT voltage Tps 51216
The ram regulator produces VTT voltage of 0.65V and the display comes. When we restart the laptop the VTT voltage becomes 0.75 and no display.[Used same ddr3l ram].
Also, it becomes 1.35 V on the ram coil and all are okay but after restarting Voltage becomes 1.5V with no display.

Hp 840 G3 Restarts Problem
HP 840 G3 On and Off problem. All voltages on coil present but only 130 mA load. AMD Graphic chip is slightly warm. Is it graphic chip faulty? In this model loads for display will be 300mA to 400mA. Suddenly it takes 100 mA or 130 mA loads. Tried new bios and same condition. When load becomes 130 mA graphic chip becomes hot. Is it possible to convert it to non-graphic?Last edited by shakib200; 10-29-2023, 04:06 AM.
