Dell Inspiron 8500 Memory problem. Cant recognize from DIMM-B slot

[Vallurupa]

Hi,
I have Dell Inspiron 8500. It came with 256MB (128MB in each slot).
I upgraded it to 1GB ( 521MB +512NB). It worked with 1gb somedays. Then it started showing 521MB. Madesure that there is not problem with memory modurels. both modurles work in DIMM A slot. But DIMM -B is not recognizing memory at all so sytem cant boot with DIMM -B. Anybody has same problem? How to fix it?
Please help me.

THanks in advance,

Kishore

If it worked correctly with 2 x 512MB previously but now Slot B doesn't recognise either module, it suggests a broken MoBo.

I suggest that you try resetting the BIOS first and check that Slot B contacts look OK and not obviously damaged. If that doesn't get it going then a replacement MoBo is th eorder of the day.

If you take out the bad MBo, it should state on it somewhere the make and model. A replacement shouldn't be too difficult to find.

Vallurupa,
Are you certain that the memory is being seated all the way in slot B?

With laptops,it can sometimes appear that the memory is all the way in when it actually isn't.

"It worked with 1gb somedays."

I would probably suspect that the sodimm being put into slot "B" isn't getting seated and worked its way out.

Cleaned the slot and then installed memory.. Holded littlebit . Then tried. It is picking now. I can see memory from both slots. Thanks a lot for your help. My laptop is fully functional.
