Howdy. I have a Toshiba Satellite l505d that I am having problems with. The laptop was working, but because of a pulled power cord breaking the power jack, I had to open it up and replace the DC power jack. Right now the laptop is getting power but when I attempt to turn the laptop on the screen remains black. The fan spins and the light comes on on the front of the laptop, but again, the screen remains completely black.

I have attempted these things thus far:

  • Removing the battery and holding down the power button
    Removing the battery completely and only using power jack
    Reseating the RAM
    Plugging in an external monitor, no display
    Plugging in a usb mouse to see if it gets power, no lights from the laser

I am not really sure what else to try, but I do need to get this laptop back up and running.

Thanks for the help ahead of time.

"You're going to want to cause a hardware hard fault.

1) Un-plug your laptop.
2) Remove the battery
3) Hold the power on button for atleast 10 seconds (This drains the CMOS Battery and any remaining power hiding in the system)
4) Access the bay where your HDD is plugged in, and remove the HDD.
5) Plug in external power and power on.
At this point windows should attempt to load normally but since the HDD is removed it will stop and give you an error and a prompt.
6) Turn off laptop via power button(Hold it if you have to, windows won't/can't load without the hdd so you're not damaging the system...

7) Unplug the external power, and drain CMOS reserve again
8) Re-insert HDD, battery, and external power in that order.
9) Power on and hopefully successful return to normal operation"

See if this works for you!
