Toshiba Laptop Black Screen

I have a Toshiba Laptop, Was reinstalling windows 7 on it last night left it doing the updates then shut it down. Turned it on this this afternoon only to find the laptop screen is Black and also there is a burning smell coming from the Fan.

I connected the Laptop to a external monitor that is fine, Can go into bios, Windows boots up fine Etc.
Just took apart the laptop earlier to check all the cables where in correctly, Checked the motherboard over for any damage, burnt bits but but found nothing. Just put it back together now but im still getting this burning smell and i still cant use the laptop screen only a external screen.

I Tried Pressing FN+F5 to switch to the laptop screen, But still black screen. Any Suggestions please ?

Thanks

 

How can I turn my laptop on from a black screen?

Hello Nishrita Dutta

Welcome to Microsoft Community.

I am aware of the present situation is that your laptop is not turning on after experiencing a black screen, in order to help you better, can you please tell me some details:

1. Can the current PC see the BIOS icon when it is first started? If so, we can try to solve this problem from other dimensions.
   
2. Assuming that the current device cannot see the BIOS interface icon, the cause of the problem may be the corruption of the BIOS /hardware damage of the CPU & GPU/failure of the cable connection of the display screen.
   
3. If it is convenient, please check whether the current notebook has an HDMI interface. If there is an HDMI interface, you can try to connect an external monitor and see if the screen can be output. Please note that if the picture is output normally, it usually represents the hardware of your CPU/GPU works normally, you may need to consider replacing the laptop screen at this time to solve the problem.
   

Here are some steps that might help you check for a black screen:

1. Check the power source: Ensure that your laptop is properly connected to a power source. If you were using the laptop on battery power, connect it to the charger and make sure the charger is working correctly.
   
2. Disconnect external devices: Remove any external devices such as USB drives, printers, or external monitors from your laptop. Sometimes, faulty external devices can cause issues with the startup process.
   
3. Perform a hard reset: To perform a hard reset, follow these steps:
   
   a. Disconnect the power adapter from the laptop.
   
   b. Dismount the back cover of the laptop and remove the battery (if it's removable).
   
   c. Press and hold the power button for about 15 seconds.
   
   d. Reconnect the power adapter (without the battery) and try turning on the laptop.
   

Assuming that none of the above steps can solve the black screen problem of the Laptop, I suggest contacting the manufacturer’s customer HP support for further diagnosis and repair. If there is important data in the current hard disk, I suggest that you try to remove the hard disk of the Laptop and install it in another computer to back up the data.

Screen turns black, system "hybernating"

Turned it on - after almost an entire day without touching it - and worked for 3 hours before the same screen black, system hibernating happened again.

Checked the temperature throughout and the cores registered at max 56 and 50.

Suggestions?
