Did you try the RAM from slot 1 in slot two and did it run OK???? If the RAM from slot 1 did NOT function right in slot 2 then slot 2 is bad and the motherboard should be replaced. Although that will be a costly fix. If the RAM from slot 1 ran fine in slot 2 then it is a RAM problem and just replace the 1 stick of bad RAM. The funny thing happens when you switch RAM sticks from slot 1 to slot 2 and the unit runs fine. You're then left scratching your head as to what the is going on. In most cases the RAM just needed to be reseated to function right.

Either memory module will work in slot 1.  The system will not boot if either module is in slot 2.  Works fine if slot 2 is empty.

You don't say what model you have so it is hard to tell you IF a single stick of 512 will work in your notebook. If the memory limit is 512 then you would need 2 sticks of 256, one in each slot, to bring it to the max memory allowed. If the memory limit is 1GB or higher then yes a single stick of 512 will work in slot 1. Although you may want to consider just using the notebook as is until it dies or need to be replaced because it become so outdated instead of investing any money into it. Since slot 2 has already died you never know when slot 1 might do the same thing. In that case you will be left with a none working notebook that you just spent money on.

That is a warranty issue if you are still in.

stupid spell checker lost my first post>

I'm working on an Inspiron 1100 that will not boot. Keyboard LEDs 1 & 3 flash 10 times then shuts down. When ALL RAM is removed keyboard LED 2 & 3 stay lite for about 10 seconds then shuts down. I have swapped DIMM A & B with each other, no fix. I have used only one DIMM (either one) in either slot, no fix, no change. I have replaced RAM with known working RAM, no fix, no change. I have removed all other components; hard drive, CDROM drive, modem, and battery, no fix, no change. I have replaced the system board and CPU processor, no fix no change.

What am I missing, is the RAM I'm using incompatible (V826632B24SATG-C0; 256MB DDR-333MHz-CL2.5; PC2700U-2533-0-A0; ProMOS Technologies)

Original RAM = MT4VDDT1664HG-265C2; PC2100-2533-1-C1; CBNBDJ5016; 200342; 128MB DDR-266-CL2.5) is it the speed?

Where can I find info on the flashing LED code or is there any?

You could do what I just did....try banging it on the table. I had just put my memory stick in again and when I was turning my laptop over it slipped and I dropped it a couple inches onto the table. I booted it up and the keyboard and everything else came on fine, but the screen still didn't work. I turned if off and then on again, and sure enough it works :)

Well it seems my particular problem was troubleshooting a defective (from Dell parts) CPU processor. After I replaced just about all replacable parts I started working backwards and discovered the CPU processor was causing problems. I replaced that with the original and all other replacement parts stayed...seems to have fixed the problems.

Thanks for all the help and suggestions.
