Phone screen goes blank to a grey color (externallY) .

This sounds like a bad display on the laptop. Hook up an external monitor to the vga port on the laptop. You may need to toggle the display to output to the external monitor. This is generally accomplished by pressing the "FN" key + one of the F# keys. Look for an icon that resembles a monitor or it may say LCD. If the graphics display correctly on the external monitor, then you will need to replace the computer screen.

Check your hardware light on the exterior of your computer and see if it is lit and blinking. If it is, you have an operating system, but just can't see it. That tells me it may be several things:

1. The LCD cutoff switch is in the off position
2. Toggle (Fn) the display to the internal settings of the LCD panel. It may be set to display an external monitor only
3. Plug in an external monitor. If it doesn't display on the external, after pressing the Fn key you have a failed video adapter. If it does display on the external it is most likely a back light or inverter failure.

I think it's probably FN+F8 that may do this on the HP laptops. The key should have a little icon on it in the same color as the function key (typically blue) that will toggle the screen from the laptop screen to the external. There are usually 3 modes to this toggle
1. Laptop screen only
2. External screen only
3. Mirrored on laptop screen and external screen

So try toggling with the FN+F8 key combination.

Also you can probably start up in safe mode to disable the external VGA toggle.

When you see the HP Splash screen, start tapping the F8 Key to bring up the boot menu. From there choose safe mode and see if you get the video back in safe mode....After that reboot and see if it will bring up the video in normal viewing mode.

Good Luck

You need to:

- Connect everything with the laptop turned off
- Boot the laptop
- Use the Fn key plus F8 or F9 (I'm trying from a small picture of the keyboard!) to cycle through the external display options.

If the laptop keeps working, and you can use it on an external screen, then it is likely an hardware fault.

First perform a complete system recovery, like probably already instructed by the Dell support helpdesk. This will practically exclude the possibility of a driver or system problem.

If the problem is hardware , then you may have a faulty inverter board , a bad LCD display/LCD ribbon connection, or a faulty video adapter (integrated with motherboard).

If the problem is the inverter, then the screen will go dark, and the laptop will keep working on external display. This is probably your case.

If the problem is LCD display or ribbon cable, then the display will be blank with light on , and the laptop will keep working on external monitor.

Fault concerning video adapter usually cause the the system not to work at all, and it is uncommon under conditions described.

If you get a call and you don't answer - it's basically a missed call. Ut displays on your external screen for a while, till the backlight goes off. While it's still displayed on your outer screen, you can use softkey on the side of the phone to acknowledge the missed call, but you can't view the details, or bring it back to the external screen once you select 'okay' or open the phone.

hi!!!

there is a setting in your desktop
try go into control panel
then click on display then go to
settings and the
advance try locate the dual monitor settings

this is a tech fault which will require a tech to deeal with it hands on

This is a hardware issue. The flex cable connecting the displays is loose or broken. If the phone is new, you can get this repaired under warranty.

your external screen needs replacing...you would have to take it to an authorised repair person to replace it because it's very tricky to change. Sam !
