I'm fixing a DELL Inspiron 3500 for someone and has 128MB RAM in it and I just got another 128MB for it to Max it out to 256MB. The problem is the 2nd RAM slot isn't reading any of the Chips. I even tested the new 128MB RAM chip and works fine. I don't know why the other RAM slot isn't reading. Also another problem with this machine is the Modem isn't reading the dialup phone line. It says NetZero is unable to properly communicate with your modem. Please make sure your modem is properly connected and turned on. It is a internal modem and has its driver installed " COM1 9600 bps modem" is what is reads.

Re: DELL Inspiron 3500 2nd RAM Slot not reading
Since the second slot is not reading either RAM module, then to fix it will require replacement of the motherboard. Motherboards for that system are cheap (Less than $50) but unless you are comfortable installing it yourself, that system really is uneconomically repairable (Cost more to fix than it is worth)

RAM modules in laptops are secured by spring clips on both sides of the RAM module. To release the RAM module press the clips away from the RAM module and the RAM module will pop up at an angle. You can then pull the RAM module away from the memory slot. Insert the RAM module in the slot, push it into th slot and then press the RAM module down until the clips on the side lock onto the RAM module.
The c600 can handle up to 512MB of RAM, so it's likely one of your RAM sticks is bad or not seated correctly. Are you using two 128MB sticks? Remove the stick from the second slot and turn on the computer with only one stick installed, and see if the RAM is recognized. Then take that RAM out and try the computer with only the other RAM stick -- if either is not recognized, that stick is bad.
If both are recognized, try reinstalling both RAM sticks and see if the computer will recognize them. If not, make sure they are both seated properly. You may have a problem with the second RAM slot if it is still not recognized. If you have access to other RAM, try that too and see if it is recognized.
The only thing you could do is put in a 256MB module in the slot that you have access to. Only one socket is user upgradable. The second socket is only upgradable by a Dell service center. They would have to install a second 256 module to get you to the 512MB max.
I assume the power LED is on when you boot up the laptop and the power adapter is OK.
If I understand you, the RAM module is in memory slot A and not in slot B. If not the RAM module needs to be in slot A.
When a laptop doesn't the RAM module may only needs re-seating or the RAM module is faulty. Re-seat the RAM module, and if this then take the RAM module and get it tested at your friendly computer shop.
There are 2 possibilities here - either the slot is not working or the RAM itself.
First install the working 128MB RAM in both memory slots one after the other and ensure that both the slots are in good shape.
Next, install the other 128MB RAM in one slot and check if this is working good.
Your laptop can support a maximum memory of 512MB. If you looking for an upgrade, please call Dell Support. Even though it's little expensive and shipping takes a week, you can get a free after sales service and peace of mind. Moreover you get proper guidance from the experts.
I had this same problem with my 600m laptop. How many times do the lights flash, before they stop flashing?
Cause: There is a physical problem with the computer that it is detecting at startup diagnostics.
Solution: You should have two pieces of RAM installed. Carefully, remove the memory slot cover. Swap the 2 pieces of memory you have in there (please follow memory installation and removal for laptops to the letter, by never touching any of the electronic contacts and handling the memory from its sides). Make sure, they sit in the slot properly (to the best you can see). Then, place back the memory cover, very carefully, and screw in. If you see the memory door cover not closing properly, the RAM might be improperly inserted. Please go back to the swapping of RAM step. :)
If this didn't work, 1 of the 2 RAM's you have are no longer functioning properly. Please follow the steps to openning the memory door again and remove RAM in "B" slot first. Then close it and try to start the computer.
If it still doing the same light flashes, open the memory door and remove RAM in slot "A". then place the RAM you removed from slot "B" into slot "A". Then start the computer again.
Yes, you can replace/upgrate the memory module under the keyboard.
Before you proceed, note that Dell Inspiron 2650 uses DDR200 3.3V SODIMM modules. Also, memory module capacities supported are 128MB and 256MB with a Maximum memory of 512MB. If the current memory installed is 128MB, you need to order 2x 256MB modules to replace/upgrade both memory slots. If the installed capacity is 256MB, you just need another 256MB for the slot underneath the laptop.
