I am going to install a wireless card in my Dell Latitude C640 laptop. I recently watched an installation video on youtube. I noticed there was some sort of wireless antenne mentioned. Are they...


i dont think the c640 usually comes with wireless so i dont think the antenna will be in there so you might have to get them. but you can take off the ram cover on the bottom and see if the wires are there. this shows the wireless card in there

I want to now which ram is used for dell latitude 640, latitude 520, latitude 430, latitude 420 and inspiron 2200 is it ddr2 or ddr1 and max capicity for upgrade


Here are the max memory and speeds:
Lat C640 is Max 512M per stick DDR-266 (PC2100) or DDR333 ( PC2700 ) for a total of 1024 Meg

Lat D520 is either 2 or 4 Meg total. DDR2-667 ( PC2-5300 )
Although the memory can be installed one module at a time, the best performance comes from using matched pairs of modules.Maximum memory for systems with the Intel 945GM chipset is 4096MB, maximum memory with the Intel 940GML chipset is 2048MB
Lat D430 has only slot with a Max of 1 Meg. You can use DDR2-667 (PC2-5300)  or DDR2-533 (PC2-4200)

Lat D420 is a max of  1.5G    . Use 1GB DDR2-533 (PC2-4200)

Inspiron 2200 is one slot with a max of 1280 Meg. recomended is 1GB DDR-333 (PC2700)

Here is a link to find almost any memory you need:

NOTE:
When mixed speeds in the same PC, the memory will run at the slowest speed installed or the highest speed allowed by your system, whichever is slower.

Good Luck

Hi Roger,

The Windows command you used to uninstall the USB port is correct. If they all work bar one, then i think its safe to say it's possibly a hardware issue.

The only other fix i can think of is to update the BIOS with the latest version from the Dell support website.



Good luck.

MotherBoard gone wild


You can replace it. But how good are you with Soldering?

The easiest (and least challenging fix) is to buy a PCMCIA USB 2.0 card. It'll fit right in your PCMCIA Slot and give you full USB 2.0 (I think your model is only 1.1 if I'm not mistaken)

They run about $20-$30 max for one of them. Just do an eBay search. They can also be ordered in at most computer and specialty laptop stores.

Memory upgrade


it's underneath the computer, behind a small panel held down by 1 or two screws..open that panel up, and either add the memory or remove what's in there, and replace it..make sure you are wiped clean from ESD(electrostatic discharge) before you touch them.
