    I've tried turning it off and on again, taking the battery out and holding the power button down etc several times, but still it stays black. I can hear the laptop making all the normal starting up noises, I just can't see anything.

    The only thing out of the ordinary seems to be that the power light (which is on) doesn't blink when I close the lid or press the power button to put it onto standby, but this could just be coincidence or something.

    It's a dell Inspiron 13z, I think I've had it about 4 years but I've never had a problem like this before. Any help would be appreciated!

    It's hard to say without seeing the device, but from what you've observed, perhaps there is something wrong with how it senses if the lid is up/down?

    It could be that there is some kind of mechanical fault on wherever it senses the lid position, so the laptop thinks it's closed (and hence turns off the screen) when it's actually open. If you're able to find this sensor (it may be hidden out of sight) then check to see if it has jammed or anything.

    Try connecting it to a monitor and if it works, your screen is broke.

    I was thinking the same. The laptop is probably detecting that the screen is closed when it is in fact open. Try and identify the area where it detects if the lid is open/closed and check it out. Alternatively, try and open and close the lid a few times but give about a 10 second gap between each open/close to give it enough time to wake up.

    If possible, connect your laptop to an external monitor to make sure that it is your laptop display that is not working and not the actual laptop computer. Otherwise, this might indicate that your laptop is faulty and not the screen part of it.

    Also, try and go into a dark room and check if you can see any faint images on your screen. It may be that the screen is faulty. You can also try putting your screen against a bright light to see if you can see anything.


    Fourthly, try and put the backlight display brightness up. It might just be turned down to the absolute minimum.


    Like ttoby said, it's hard to tell without seeing the device. These are just general troubleshooting tips you can use to help identify what may be wrong.

    Thanks for all the replies, I can't get any of that to work so I think it must be the laptop itself that's gone wrong. The only bit I didn't try was the finding the sensor when I'm opening and closing it- how would I go about doing this? I might just have to take it down to the computer repair shop place tomorrow

    On an old laptop I had, the sensor was a little rod that stuck out and got pushed in when the lid closed. On a newer laptop, I think it's built into the hinge somewhere so it's not so easy to get to. Hopefully the repair shop would know what to look for and would have the required tools to use if necessary.

    I had the exact same problem, and sent it to KNOWHOW at PC world/currys and they said there was something wrong with the motherboard. And then came the new that it will take roughly £250 to fix :| Took it straight back! But they were able to do something, they made it work on an external device like my computer screen!

    Ahh, don't want to have to pay that much! At least it's not just me though.... So you can still use it, just not as a portable laptop?

    Yeah that's what i thought, I was not ever going to pay that much to fix a laptop ,most probably buy a new one later! I can still use it as long as i attach the cable from the computer screen to the laptop then i can see what i'm doing on the computer screen! What laptop do you have?

    A dell inspiron one- it's a brilliant laptop, I've almost run out of memory but that's the only problem I've had with it until now. Hopefully I'll be able to do that then, especially as I need things saved off it! If not, as you say I'd rather just start saving to buy a new one than pay £250 to repair it

    Thanks for all the help people, I was going to take it in this morning but my mum just before we went in said 'have you tried shaking it?'. She did and it works now, so we thingk there must have been a crumb in there or something? Anyway, I now have a working laptop without having to pay £250 or something that I can't afford, which is good!

    That's great! Although, if that fixed it then it could be an intermittent fault so you might find it happens again. I'd recommend backing up anything important on the laptop just in case.

    Shaking it sounds like a loose wire more than anything, so as the poster above says there's a risk it might recur, and I wouldn't recommend shaking your laptop to fix it every time! You might be able to take it to a computer repair shop to get them to diagnose it - some places will offer to identify the problem for free (or at least cheaply) without any obligation for you to go ahead with the repair if you don't want to.

    Yeah, I think I might do that when exams are over and I don't need it so often, hopefully it won't happen again until then. I don't intend to shake it again if I can help it!
