Suddenly, the display went dark when I disconnected the power of some hardware that was connected to usb with the laptop. External monitor works. All status lights work.
When I light up the display with a flashlight, then it shows that just the backlight of the display seems to be out.
So I suspect that it is just a fuse on the board.
Does anybody know where this fuse is (location, marks etc) and with what I should replace it?
(I know that fuses are always near the connector and should be marked with f or something. But, I guess I wont trust myself in this. I do not feel able to discern the different components myself.
Close to what appears to be the display connector, there is something looking like a fuse that is called P7... But I do not know if it is this. Does somebody know where this fuse is exactly?
Do I simply have to soldier one on top or do I have to replace the fuse? With what fuse do I have to replace? Which ampere, which other data? Where can I buy it? I live in germany..
Thank you for answers.
I guess the relevant fuse is the thing marked as PF1 with a 7 on it that I have encircled.
But I really do not know. Is this the fuse? and with what would I have to replace it?
Can I order such things in an electronics store?

Espero que puedan ayudarme con ésto.
Desde ya muchas gracias.
Keep in mind that usually USB power line is separated from other power lines so this should not kill backlight fuse (unless there's some design flaw in motherboards layout). On the other hand there's well known problem with an eDP cable which breaks and causes short of the power line circuit. This happens whenever cable is routed incorrectly. One of my units has been affected by this problem due to incorrect cable routing made by authorized technician during motherboard replacement. So keep in mind that fuse re-soldering may not solve the problem completely.
