Armada 7400 won't charge - clicking noise around power entry
When I plug in the power cord, I can hear a clicking sound around the
power entry area. If the machine is on battery power, the screen flashes like it's changing from AC power to battery power and back. I can't tell if the power supply is bad or some portion of the mainboard in the laptop has gone out. 9 out of 10 times, I can't get it to charge the battery. I measured the output on the power supply ~14VDC. Any help is greatly appreciated. JM89 |
