I acquired a dead compaq cq62 motherboard yesterday. When I attach power adapter no led light in dc jack which indicates no power. I have check board and there seems no heating components and all is looking good. decided to program bios with the file downloaded on HP website.
After bios flash dc jack now has led light indication that it receives power. When I press power button it turns on but there is no display on external monitor. tested different memory and still no display. I cannot test it with lcd panel because I don't have any spare here and owner didn't have it too. I don't have keyboard too.
Does this indicate that bios reprogram is a fail? I also notice that if I press power button again it turns off, Its like commencing correct power off command. I usually see laptop with vga issue which does not turn off when power button is pressed. any ideas? Thanks.
