Question about Compaq Computers & Internet
Have compaq c503wm laptop push power button front light shows charging, after pushing power button about 5-15 seconds power button starts blinking and power light on front blinks. nothing starts to boot. (replaced Motherboard, CPU, Power Button,
Mainboard AC power Cable new cables with power button, AC adapter also. Did exact same thing with old mainboard and other parts Won't boot when you push power either with battery in or out power button just flashes continously hard drive light flickers 2-3 times then goes out and just flashing power light on button and front panel left . Battery shows charging when battery is installed replaced cmos battery also.
Have you tried attaching an external monitor when the LCD screen is disconnected from the motherboard? this connector is located under the keyboard strip – a piece of plastic just above the keyboard.
If it works, this way, then the video cable isn’t seated properly in the connector on the back of the screen. Plugging the video cable back in should fix the problem.
I don’t know how comfortable you are with taking apart laptops but I think that this information could be useful for you.
