Laptop stuck at 800x600

If the unit powers up and it seems to work except for the screen, hook a external monitor to the video output usually on the back, if picture is present! the laptop has issues. But if both screens show the same symptom the problem is in the video graphics card.

If you don't get a display on the external monitor, then most likely your video circuit is the problem. If your laptop has a plug-in video card it can be replaced. However if it's integrated into the motherboard then you'll have to have that replaced.

Assuming the graphics drivers are up to date and assuming you have a high resolution set in the display on the control panel, the screen may be damaged or the VGA cable damaged. In extreme cases the onboard chip may be loosning from the motherboard. You cannot install an external graphics card on this laptop. I would check the above and see if the existing setup can be repaired economically

Provided the screen is the only thing damaged, you have several options.

1. Connect and external monitor and use it to see what you are doing while you copy you photos to other media. (Fn+F8 enable external monitor)
   
2. Remove the HDD, connect it to another system using a USB adapter, and copy your files: http://www.amazon.com/Universal-Drive-Adapter-Serial-ATAPI/dp/B0012TOG08
   
3. Replace the broken lcd: http://cgi.ebay.com/DELL-LATITUDE-D620-D630-COMPLETE-LCD-WARRANTY_W0QQitemZ220582533329QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item335bbe58d1

Yes, but you will need a dvi to vga adapter.
Or one of the monitor must have a dvi input.

When powering on the D630 from the Docking Station, press F2 to go into Setup. Scroll down to the Docking Section, and check the Dock device info for the status. If it shows undocked, then try changing the below settings to: Hot Undock, Enabled Silent, and Universal Connect Enabled. Save these settings. Make sure you update your BIOS to A16 from http://support.dell.com under drivers and downloads section. If still not recognized after this, check the dock port on the D630 for obstructions or burn markings on the pins. try cleaning with rubbing alcohol and qtip swab. I have seen a few cases like this and ultimately the motherboard was the issue and needed to be replaced.

Try updating to BIOS to version A16 from http://support.dell.com Ensure you are not attached to the docking station when flashing the BIOS. Once updated, connect the 90W adapter to the docking station, connect your laptop to the dock, and power on using the docking station power button.

Basically you most likely have a corrupt hardware profile. Delete the profile for docked and try again, this normally works.....Mark
