Diconnect the video cable from the laptop to the monitor and do the Fn Key combination to see if it goes back to the laptop screen.

SOURCE: Dell Latitude d620 display problem

Sounds like your computer has just bit the dust, do your self a favor and purchase a new one. This time buy an XP, it might be a little bit more, but you get what you pay for.

SOURCE: Dell Latitude D620 no display on main screen!!

Had a similar problem, some video "jitter" and then the screen washes out with backlight showing. ONLY HAPPENS when under battery power.

Cause: a recent reinstall of XP SP3 realized a newer video driver, intel integrated 945gm, than was on the Dell support site. This newer driver is problematic.

Download and install the Dell support site's OLDER video driver for the D620. A new battery won't help, only the older driver.

SOURCE: Aspire Notebook 5735-4774 won't display on external CRT monitor

If the video chip on the Aspire motherboard is OK then the image on the external monitor would be OK. If not then the video/motherboard is faulty.
To gain access to data on the hard disk, remove the hard disk and connect it to an USB hard drive adapter and plug it into a working computer's USB port. The computer will see this as an external hard drive.
Alternately -
You can put the hard drive in an USB hard drive adapter case and use it as an external USB hard drive.

Things to check:

1. Is your display automatically transfer to the projetor right away when you plug the VGA/HDMI cable to the computer? If not, and Fn+F8 doesn't do anything, try to press the Windows Key+P (the windows key looks like this ray_tosh_1.jpg ). This will allow you to switch between displays. (see image below).

2. If you choose one of the display mode above and it still won't clone/extend the image on your computer to the projector, try to use a different cable. If still no go, try to re-install the display driver and see if that fixes it. If same issue, there might be a problem with your VGA/HDMI/Display port and needs to be serviced.

Good luck

Dell d620 sCREEN GOES BLACK AFTER WINDOWS SCREEN COMES UP. None of the normal Fn keystrokes help. i never make it to the login screen. Help?


If your laptop appears to boot up and the hard disk LED flashes, then the problem is probably a back light fault. This can be a faulty inverter or a faulty CCFL lamp. Please click on this link and follow my instructions to identify the fault and possible fix :- http://www.fixya.com/support/r3598095-faulty_laptop_lcd_screen

Dell latitude D630 wont recognize projector


Connecting an External Monitor or Data Projector
You can switch to an external monitor or data projector by two methods. 1. Connect the external monitor to the laptop's video port, power up the external monitor first and the laptop. The video information will automatically switch to the external monitor. 2. If you power up the laptop first then you can switch the video output to the external monitor by pressing the Fn key and one of the Function keys, depending upon your make and model laptop. You can also toggle between the external monitor or both LCD screen plus the external monitor or back to LCD screen only by pressing the Fn key plus one of the function key. Here is a list of key combinations for some of the laptops :- IBM ThinkPad = Fn + F7 HP and Compaq = Fn + F4 Toshiba = Fn + F5 Dell = Fn + F8

How to hook up Dell laptop to Samsung Dlp tv?


Your Dell D620 only has a VGA Port for output to a external monitor or tv. Your TV will need to have a VGA Port too, otherwise you will need some type of adapter that goes between the laptop and the tv to convert to the type of connection the tv has (svideo, hdmi, dvi, etc.)

One you have the two connections set up to communicate with each other, just select the input source on the tv (pc, computer, hdmi, etc) and then reboot the computer if the image is not show.

After rebooting if the image is not shown, then you will need to toggle the display by some keystrokes. Press and Hold the Fn function key at the lower left hand portion of the keyboard, then hit the F8 key which toggles the display to be either on the laptop only, tv only, both the laptop and tv.

Hi, I have a Dell Latitude D830. The display was off. I can connect extrenal monitor for current work. Please advise if I need replace display or motherboard ? Thanks Alex


Before replacing anything verify that your laptops display type didn't get changed to VGA out only.
look at your function keys (usually top one or two rows ) and look for the key that has a pc/monitor icon. with the machine powered up and connected to the external monitor press the function (FN button lower left of keyboard) and the video/monitor button at the same time. most laptops have 3 settings:
laptop display only, external display only and laptop and external display. Press the FN/Display button at lease 3 times waiting 3-5 seconds between keystrokes. I have seen this many times where the FN/display button keys are hit inadvertently.
Typically if the motherboard or video card fail the external monitor would not work either.

Problems with external monitor


Typical issue is the second monitor resolution got set too high for the monitor to generate a picture. Go to display settings and adjust the resolution down to see if it comes back.
