Laptop screen can only be seen when it is open at certain angles?.?

A few months ago after taking my laptop out of my sister's room, I opened it and the screen was completely black. I could only see vague shadows of the window that was currently on the screen. However, when I completely open the laptop, the screen turned on and worked fine. Up until now, if I keep the screen completely open, I can use my laptop very easily. But if I do not open it completely(like if the screen and the keyboard cross at a right angle), the screen is black. This got very annoying but I quickly got used to it. The screen could also be seen when the laptop was almost closed. The screen has recently gone entirely black except when it is almost closed. This makes it close to impossible to use the laptop. Is there anything I can do to fix this? There is nothing wrong with the laptop except the screen which doesn't work properly. If I can't fix this, is it possible to get a replacement screen for a laptop that I could somehow hook up to it and use?

1. i think that your sister broke your laptop and you are probably going to have to get a new one sorry.


2. It might be a privacy screen on it.... so that you can only see the screen if you look at it straight on.


3. Yeah, it's because its something wrong with the screen sensor on the laptop. It makes the screen turn off when you lock it.


4. Laptop screens have a backlight which is automatically turned off when the screen and keyboard are at a 45 degree angle, because this means that the user is no longer using the laptop and is in the midst of closing the lid.

   In Linux you can change this setting so that the backlight isn't turned off, but in Windows you can't change that, you can stop it from going into stand by but you can't stop the backlight from turning off.



5. try dis..

   Press n hold d 'Fn' key (if available) next 2 d left ctrl button n tap d ryt arrow button on ur keyboard..

   Dis shud work..

   Gud luck



6. You need an honest engineer. laptops are not dead easy to disassemble without breaking, and yours needs a bit of that.

   if you are (very) lucky, your honest engineer will find a loose connection and fix it for a minor fee.

   More likely you will need a new laptop to screen cable, which depending on your make of laptop can be pricey / hard to find.

   IF you want to DIY, buy the service manual / disk for your model of laptop it should tell you how to get it apart.

   Most laptops have a cover along the top of the laptop above the keyboard and below the screen, getting that off would be a good start, because some screen connectors usually lurk under there, and you can try pressing them with a finger tip to see if one causes the light to go on/off.

   I will say though, that the average person, is unlikely to fix this fault successfully, if you got access to an honest engineer, use him, and pay him slightly more than he asks for...
