Dell Latitude D610 laptop has two memory slots available for upgrades. This laptop can take up to 2GB, so you can install up to 1GB memory module in each slot.
You should use PC2-4200 DDR2-533 SODIMM memory modules. Your laptop will work in dual channel mode (recommended) if you install two identical memory modules. In my case, I’m going to install two 1GB PC2-4200 modules.
One of the memory slots (Slot B) can be accessed through the door on the bottom of the laptop. The second slot (Slot A) is hidden under the keyboard, so we’ll have to remove the keyboard. If your laptop was configured with only one memory module, you’ll find it in slot A.
Before you do anything, do not forget to remove the battery.

Let’s remove the keyboard. Insert a flat head screwdriver between the keyboard bezel and laptop case and carefully lift up the bezel. Remove the bezel.

You’ll find two screws securing the keyboard. Remove both screws.

Now carefully lift up the keyboard. You’ll see the default memory module under the keyboard, right above the touch pad buttons. It’s possible to replace the memory module without disconnecting the keyboard.

I will disconnect the keyboard so I can make better pictures for you. Simply grab the blue tag attached to the keyboard connector and pull it up. Now you can remove the keyboard.

On the picture below you can see the default memory module installed into the slot A. In order to remove it, spread latches on both side with your fingers.

The memory module will pop up at a 30 degree angle.

Now you can pull the default memory module from the slot and replace it with a new one.
I’m installing a 1GB module into this slot.

Finally, install another 1GB module into the slot on the bottom. Turn on the laptop and you are ready to go!

Jay,
Here’s how I fixed a faulty memory slot with a guitar pick.
If one of the memory slots is bad, I guess you’ll have to replaced the motherboard and use it as is. There is no easy fix for that.
It’s possible that the memory slot fails because one of the solder joints is cracked and has to be resoldered but I doubt you can repair these type of failures at home. You have to have the right equipment and lots of soldering experience.

Thanks, this will help. I need to upgrade the memory in the A slot.
Recently, my D610 would not power up. It fired up for about 10 seconds then quit with no message. It turned out that the B slot was the culprit. Now the D610 works fine but only if I leave the B slot empty.
Do you know of any inexpensive fix for that?

Thanks. I was wondering where this illusive RAM slot was.

Thanks for the assistance, it was straight forward and I was able to do this myself saving me tons of money.

Did this with my old Dell Inspiron which was very easy but confused as to where the other stick of ram was hiding. Thanks for the pictorial steps.

My computer will not see the new memory on the bottom. I’ve changed both memory around and both are good. The computer only sees the memory under the keyboard. I’ve checked the CMOS and there’s no way to add memory there. Any ideas?
