Laptop goes


You must, when using an external monitor, either press the relative 'F' key to switch the external signal on or boot with the external monitor plugged in to get it to work.

Please help, My laptop Toshiba Satellite L645 blank screen when turned on, there is absolutely no view. please help me ..................


Can you tell if the laptop itself is turning on?

If not then there is an issue with the laptop.

If the laptop is turning on then try plugging in the laptop to an external monitor and see if you get anything on the screen. If the laptop works normally with the external monitor then you will need the screen replaced . If the laptop still shows nothing on the external monitor then you will need to repair your laptop.

Please rate if this helps

So I'm turning on my inspiron 5100 and all i get is a white screen. It sounds like it's on but the screen remains blank white?


Hi Donny,

A white screen usually means the LCD panel has failed/worn out. Here's an easy way to make sure. Get your laptop to an external monitor, whether at your home or a friend's place, and with the laptop off and the external monitor off, connect the monitor video (vga) cable to your laptop. Turn them both on and then on your Dell laptop hold down the fn key down in the bottom left hand corner of the keyboard and press the F8 key up at the top. That transfers the video signal to the external monitor.

If the external monitor shows your laptops normal desktop and icons, then you know for sure the LCD screen on your laptop is worn out. If you get the same white screen on the external monitor, it means the video card/controller on the motherboard of your laptop has worn out and you can move ahead with deciding on repairs or other options.

Good Luck.

PS....if the F8 key doesn't transfer the video signal. look at all the F keys for one that says CRT or one that has a little picture of a monitor to transfer the signal.

Computer was working fine we powered it up and the screen is white nothing else happens


What happens if you connect an external monitor to the VGA port on the laptop? Is the output "white", or is it what you expect?

If your LCD shows 100% white, then the LCD is not getting the correct "signals" from the computer's video-card.

Take your laptop to a qualified technician, for trouble-shooting.

"no signal"


"no signal" means that the monitor is not receiving a video signal from your computer or laptop. This is normal if the compouter is OFF and the monitor is ON. Is the computer still on and connected to the monitor?

HP (dv2000) laptop will not boot up at all


It appears to be a video card/mainboard problem very common with the symptoms you have described. Try to connect the laptop to an external monitor (see the associated buttons too). No video signal on the external monitor could indicate a damaged video card/mainboard. Not worth it to be repaired and the replacement is expansive. Check the price on a professional repair store. There are new laptops on the market more powerful than yours for about 500-600$. So you can make a choice. Less common, could be a memory problem.Try the laptop with a good previously checked memory (or if there are 2 bars in your laptop, try them one by one). If you do not get any video signal on the external monitor have the laptop, first diagnostic is most probable.
In both cases, if you get a video signal on the external monitor it means your screen is defective (also expensive to be replaced).

We have the monitor hooked to a docking station for a laptop. I can not view the screen on the Viewsonic, but does display on laptop. I have been able to do an extende monitor view, but not the main view....


when you connect external monitor to a laptop u get two options in the monitor section of graphic properties tab

1.) extended
2.) clone

it is clear from ur post that u are using extended view

try using clone mode then both laptop screen and external monitor will show the main screen


other method is to disable the laptop screen and just allow external monitor to work, in this case laptop screen shows nothing but external monitor shows main screen

Data Shows up only on External Monitor, not on Laptop Screen


If your system won't display anything w/o the external monitor. there's something wrong with the LCD's backlight. you may have to contact your laptop's manufacturer and check if this laptop is still under warranty. you may have to get the lcd replaced.

thanks.
