Top 10 Dell Latitude C640 Notebook Questions & Answers

I used Everest home edition to find the wireless drivers for my DELL C640 laptop.   The wireless card in it is an  ntel PRO/Wireless LAN 2100 3B MiniPCI Adapter (IBM). I've downloaded the wireless driver from Intel's website, here: 
http://downloadcenter.intel.com/filter_results.aspx?strTypes=all&ProductID=944&OSFullName=Windows*+XP+Professional〈=eng&strOSs=44&submit=Go!#DRI
It's the 3rd result in that search page. If the link doesn't work, simply search for Intel® PRO/Wireless 2100 Network Connection on Intel's site. 
That Dell C640 wireless driver works fine for me, I'm using the wireless card to type this :)    
good luck!

I purchased a Genuine Dell Battery, It arrived dead with 1 test light on battery itself at 0% charged, It only lasted 2 mins before the laptop died running on battery, It doesn't charge the Dell battery at all The replacement battery only shows a 1% charge every 7 hours or so, nor do I have a yellow, green, orange light, The only time I get a light on the battery led is if i'm running on batteries and the battery level is below 10%, Its orange for low battery.
Thanks in advance to anyone who could help me.

I am using the dell system at XPS710 and i kept getting the bios error:
No boot device available

I tried to hit F1, then i get that message again. I hit F2, then it i didn't see the problem.

PLEASE HELP! No ignores!

Normally you have to use Fn(function key) on your keyboard + F4 key (F4 or maybe some other key you have to see and icon on your F4,F10 key..it should look like a a monitor icon) try it.
Press Fn first and hold it and press F4....
The first time it should output only to your S-video,second pressing it should output both s-video and your monitor.
goodluck,takecare.

Daustie, you don't read much, do you? What betenikomila is looking for an answer to is the BIOS/CMOS password, not the windows pass as you misguidedly offered bad advice to fixing.
What is needed is to do a procedure called "clearing NVRAM". The nvram is the non volatile memory that you computer keeps setting such as time, date, drives installed, and boot process. Think of it as the brains of the computer that tell it how to do the basic things.
The steps that follow are from Dell's website. PLEASE follow EXACTLY what it says, because you need to go inside the case & one small slip will cause your computer to become nothing more than a shiny doorstop. If you feel uncomfortable doing this, get someone that you trust to do it.

To clear NVRAM for all devices and restart the system, perform the following steps:

1. Turn off the computer and unplug it from the electrical outlet.

2. Remove the computer cover.

3. Move the jumper plug on the JPX2 jumper to pins 2 and 3 to erase all settings in System Setup at system start-up.

4. Replace the computer cover.

5. Attach the computer to the electrical outlet and turn it on.

6. After the system boots, turn it off, and unplug it from the electrical outlet.

7. Remove the computer cover.

8. Move the jumper plug on the JPX2 jumper back to pins 1 and 2.

9. Replace the computer cover.

10. Attach the computer to the electrical outlet and turn it on.

Your hard disk is disconnected, or not configured correctly in the CMOS. Go to the BIOS and be sure that the computer recognizes the hard disk. If doesnt happens, check the connectors, and if it doesnt fix your problem, you need a new hard drive.
