My dell vostro laptop screen goes blank after several seconds or minutes, it highly varies, sometime it just goes off right after the dell logo or sometimes it goes of after minutes. I haven't change any hardware. But, the laptop was not turned on for 1 Year now.
You say the display goes blank, but that doesn't mean it isn't on. It just means you can't see anything.
If there are any signs of life, lights, internal sounds, etc., then it is on. In that case, since you say you can see the logo screen etc, then try the following...
Option 1 ...
First, while the computer is off, connect an external monitor.
Next turn on the computer and allow it to fully load.
Once loaded, press the "Windows Key" + "P" to open the "Easy Display Switcher".
In here select "Computer only".
Now shut down the computer and disconnect the external monitor.
Disconnect the external monitor
And finally restart the computer.
Option 2 ...
Make sure you wait until the computer would be fully loaded before trying this, and not try it right away like you would to say get into BIOS. This needs you to actually be where you would be when Windows Explorer loads.
1. Press "Shift" repeatedly until the "sticky keys" window shows up.
2. Now click the the link there that will lead to the "Ease of Access Center".
3. Next click "Cancel" on the the bottom right corner of the "Set Up Sticky Keys" window.
4. From here you want to click "Control Panel" on the upper left corner (it should be right beside the "Make Your Computer Easier to Use" title.
5. Locate the "Computer Settings" menu and then choose the "Recovery" icon (make sure that your view of this is by either large or small icons for easier access).
6. Now click and open "System Restore".
7. Here you want to click next on the bottom right corner (a few times) until the button "Finish" shows up and then click it. (Just follow everything prompt that the window says which will lead you to recovering your previous system, in a certain time.
8. The computer will now do the work it needs to and then reboot.
If that doesn't work, you can try the following...
You can also try doing the Ctrl+Alt+Delete and see if you can get "Task Manager" to show.
If the "Task Manager" windows shows, then choose "New Task" and then type in EXPLORER. If the desktop shows up then you need to go into "Start", "Programs", then "Accessories" and finally "Command Prompt". (Or you can do a search for CMD.)
Make sure you load the "Command Prompt" with Administrator access. Then when it loads type in....
If none of this works, then it may be the GPU you are using, if not using the integrated graphics. You can test it by turning on the laptop in "Safe Mode". If it will load then, and show you Windows, then your GPU may need replacing.
Hii, Thanks for the helpful reply. Yes indeed laptop is on just the screen goes blank and I can't perform any of your solution as the windows is crashed "blue screen of death" . Sometimes screen not even stays untils I see windows logo. I replaced the screen but the result is the same.
That doesn't sound the like the display is the problem. It sounds like something else. If it were the display itself then it would never show you anything.
Did you try starting up in "Safe Mode" to see if it will load?
How to enter "Safe Mode" when booting the computer.
In Windows 8 and 10...
As your computer restarts, press F8 (possibly a few times) to enter "Safe Mode"
a. Press the "F4" key to Enable "Safe Mode".
(The computer will then start in "Safe Mode" with a minimal set of drivers and services.)
b. Press the "F5" key to Enable "Safe Mode" with Networking.
( Once "Safe Mode" with Networking starts, Windows is in Safe Mode, with additional network and services for accessing the Internet and other computers on your network.)
c. Press the "F6" key to Enable "Safe Mode" with Command Prompt.
(In "Safe Mode" with "Command Prompt" starts Windows in Safe Mode, with a Command Prompt window instead of the Windows interface. This option is mostly only used by IT professionals.)
Now sign in to the computer with your account name and password. (If you have one set.) When you are finished troubleshooting, you can exit "Safe Mode" restarting your computer.
In Windows 7/Vista/XP...
1. Immediately after turning on the computer, or restarting it (usually after you hear your computer beep), tap the F8 key, repeatedly, in 1 second intervals.
2. The computer will then display hardware information and run a memory test.
3. Next the "Advanced Boot Options" menu will appear.
4. In the "Advanced Boot Options" menu use the arrow keys to select "Safe Mode" or "Safe Mode with Networking" and press ENTER.
