Windows Vista is not supported on Dell Latitude C540/C640. There are no drivers for the hardware of this model. Many older computers have that problem. You can try Microsoft to see if they even exist: http://www.microsoft.com/uk/windows/products/windowsvista/buyorupgrade/upgradeadvisor.mspx
You might have to fall back to XP.

Hi, the latitude c640 starts to boot and cuts out - no way of getting into bios, doesn't even start showing the bios before it dies, any help? andy


This could be a heat problem if the processor heatsink has become unseated or filled up with dust/hair/ etc.
remove the 6 screws labeled "k" from the bottom, remove the keyboard and inspect/clean it.

Well yes and no. Yes you can uninstall the software but then you will not have any wireless connection. Unless you are going to replace it with something else.

C640 sVideo problem


you definitely need to get the drivedr for the svideo option. it wil actually not show you in the device manager the svideo, but the graphics card details only. to find out if you have a secondary display (svideo) you have to go to your display properties then and see if you have dual display. try to bott also your dell with the svideo-tv already connected and see if you get a post display on your tv. now... i need to know only if your svideo is active, drivers will still be need to get the windows work there.

Keyboard problem


You just need a new keyboard - those are easy to come by check ebay.com and search for C640 keyboard. New ones should only be about $30-$40.

To remove the keyboard you just remove all the screws on the bottom of the laptop that are marked with the letter "K" then carefully pop the keyboard up.

Let us know if you need further help!

This is a rather old question, but the solution might still be helpful to other readers.

I suggest you call Tech Support at Dell...

Several years ago, I worked on many Dell CPx 500 models in my work place. There was an issue that always involved a series of 4 or 5 keys (they were always the same keys) that would quit working and we had attempted to purchase new keyboards to fix the issue. It turned out, the real solution was to replace the 'motherboard' of the Latitude notebook!

Dell had knowledge about the keyboard/motherboard issue that we didn't know.

Dell latitude display settings


On most Dell laptops it's not listed on the display settings. You have to enable it manually.

On the bottom left of your keyboard you'll see a blue Fn (function) key. Hold that down and scan your F keys at the top of the keyboard. You're looking for one that has (in blue, like the Fn key) CRT/LCD marked on it. Hit that and then let up on both keys. It has three settings 1) internal LCD, 2) external CRT (cathode ray tube, but an external LCD applies, too) and 3) both internal and external (this can be a little tricky with older video cards, especially when used with something like a projector). Each time you use the CRT/LCD switch it toggles between these three modes.

Let us know how it turns out!
