Hi,

The LCD backlight on my HP ZBook Studio G3 isn't working. Using a flashlight I can see that the display is working so it's not totally dead.

I'm guessing it's either a blown backlight fuse, or a broken backlight.

Does anyone know where the fuse is for the display backlight? I looked at the "HP ZBook G3 Backlight Fuse Location" and disassembled my laptop, but the only fuse I can find seems to not be blown, testing it with my multimeter a few nights ago showed about 2-3 Ohms. I'm not sure I'm testing the correct fuse, though.

Linked images show both sides of the motherboard. The fuse I've found and tested is the one labeled "F2", indicated by the big red arrow.

If that's the correct fuse then I guess the backlight is broken. If that's the case, does anyone here have any tips or pointers to where I can purchase a new one, and how to replace it?

Thanks,

is the video ribbon cable still connected correctly? unplug and replug on the motherboard and the display and check display light again

Thanks, I'll check that.

I realized I wrote "HP ZBook G3" in my first post, when I meant "HP ZBook Studio G3". I've got a HP ZBook Studio G3 which is why the fuse identified in the "HP ZBook G3 Backlight Fuse Location" thread can't be found on my motherboard, and also why my images differ from the images in that other thread.

So before I reassemble the laptop to make sure it's not just the ribbon cable, can anyone point out the LCD Backlight fuse location on the HP ZBook Studio G3?
