Question HP ZBook G3 Backlight Fuse Location

[jmo1112]

Hi. Does anyone know where the fuse is for the display backlight for an HP Zbook 15 G3? Pretty sure I blew it on a display replacement, but I'm just not sure of it's location on the motherboard. Google hasn't exactly helped me in this instance, unfortunately.

If pictures would help, here are some. The part highlighted in green does not pass continuity. Would that be the fuse?

The insert pic wouldn't work, so all I can do is post a link.

If anyone runs across this issue on an HP Zbook 15 G3, and probably works for the 17G3 with the motherboard 848221-001, you the fuse is on the UNDER side of the board. As in you have to remove the motherboard to get to it. The service videos on HP's site for this laptop are actually pretty great, so follow those for system board removal. Here are pics of the underside of the board and the fuse highlighted.

Sounds good, was it just broken fuse or damaged chip? Its fixed now or you need help to further diagnose? You can put this solved by your own message.

It was just a broken fuse. When I was replacing the display, I didn’t disconnect the battery (doh!), so it popped the fuse. Just did a solder blob to bypass it, as I didn’t have a replacement part. Issue is now solved.

You got lucky there, i would of done same if i dont have fuse. You could replace it with littelfuse : https://www.ebay.com/sch/i.html?_fr...t=0&LH_TitleDesc=0&_osacat=0&_odkw=littelfuse
