Hello everyone and happy new year.
I've been having a problem with my laptop for the past 2 days.
When I turn it on, the screen stays black; if I shine a flashlight in front of it, I can see the menu,
but the screen is dark, kind of like there's no battery.
Then I noticed this morning that depending on the angle, the screen either lights up normally or not.
Where could this be coming from? Because it has never been dropped.
I noticed that it lights up normally when it's almost closed, so I can't do anything with it.
Thank you for your responses.

    verdict: I just did everything as shown in the video. But it's still not working. I'm going to try again to unplug the power supply...

    I just noticed that when I press the top right, the screen lights up normally, and as soon as I remove my hand, it stops working and goes black again.

    You have flat cable bundles with connectors... you gently remove them and put them back in the right direction, but generally, you can't put them in backwards...!--

      I think I found out that it comes from a cable. Because when the screen is upright and I press on the cable, it works, but when I lift my finger, the screen goes black again. It seems to be the cable coming from the inverter board. But I think the problem comes from the connections under the PC.
      So now I don't really know what to do.

    So here’s the report: when a screen has this problem, it's due to the inverter cable.
    But it's a rip-off to have it repaired. I paid 18 euros for the part, plus 16 euros for shipping directly from the Fujitsu website, and 70 euros for labor because apparently, my PC is a nightmare to take apart. So the problem is fixed. Thanks for your help.

    Your PC has probably crashed! If so, there is certainly a loose cable or something that is making a bad connection; otherwise,

    check the display settings.

    no, I'm not good at computers. Personally, it didn't fall down, I'm sure of it; it could be a shock during transport because I don't remember hitting it. I'd like to check the screen settings, but the screen is too dark to see clearly what is written.

    you can try this
    disconnect the power supply, press and hold the power button for at least 10 seconds, replace the battery, plug it back into the mains, press the power button.

    Thank you, I'm going to embark on an adventure away from my screen, I hope I don't damage it.

    J'ai déjà essayé le système débrancher-rebrancher avant de poster le message, mais ça n'a pas marché.

    Hello...

    You clearly have a loose connection somewhere... I think you need to consider opening it up....

      I just did it, so I followed the video. I put the cards back in properly, but still nothing. Now, how can I find out where the faulty connection is?

    In my opinion, you need to look where it works when you press it, but also at the hinges... all the moving parts... --

      Do you think I can do it while the computer is on?

    Well, since I don't have the machine in front of me, I can't give you too much advice... it's also about not breaking something... I think that having located the problem, a shop could do it for not "too" much, but well...?!
    Good luck,
    Best regards,
    See you later

      I think you're right now that I know the problem, I'll stop disassembling and on Monday I'll go to Surcouf. Thank you for your help.

      remove the battery or you risk frying the hard drive by touching a circuit

    "Happy" for you that it's fixed, even though it's not cheap, indeed... but it's true that few phones can be disassembled in 15 minutes, which, of course, translates to quite a lot of labor hours, pretty expensive too!
    Best regards,
    See you later
