Remove memory modules one by one. Try starting the laptop with only one memory module in place. Try different slots. This way you can find the faulty slot. Maybe this trick will help: http://www.laptoprepair101.com/laptop/2008/02/28/fix-laptop-memory-slot-failure/ You'll have to install memory in the faulty slot and apply some pressure on the module. steve,

Systeminfo on my NC6400 tells me I have 1 GB installed memory. Can I just buy one 2GB module to upgrade to 3 GB.

Yes, you can.

Or does it need to be an equal duo, in other words, the same amount of GBs in each slot?

Nope, it’s not necessary.

One question: Systeminfo on my NC6400 tells me I have 1 GB installed memory. Can I just buy one 2GB module to upgrade to 3 GB. Or does it need to be an equal duo, in other words, the same amount of GBs in each slot? I read this somewhere but not sure if that is right. If it is true I would have to buy two modules in order to upgrade to 3 GB, instead of just one module. Thanks Ronald Hi,

Thanks for the instructions, very helpful.
One question:
Systeminfo on my NC6400 tells me I have 1 GB installed memory. Can I just buy one 2GB module to upgrade to 3 GB. Or does it need to be an equal duo, in other words, the same amount of GBs in each slot? I read this somewhere but not sure if that is right. If it is true I would have to buy two modules in order to upgrade to 3 GB, instead of just one module.

Thanks

Just google <b><i>2GB DDR2 PC2-5300 667MHz SODIMM</i></b> and you'll get an idea how much it is.

It worked perfectly. I had to peel back some of the plastic backing, and push my dents out with a screwdriver. Got all my letters even. Plenty of adhesive left on the backing too, so i didn't have to reglue it. Keybord is even and works perfectly. How much do the 2 gb ram sticks cost for this nc6400? I'm anxious to upgrade.
