Upgrade RAM. Problem re-booting

Hi
I have an Asus Eee PC Series (504 MB Ram / 4GB hard drive). I bought 2GB of memory (Hynix 2GB DDR2-667 sodium) but when I replace the old memory with the new, the laptop wont boot up. In fact the only activity I see is the green power light and the blue wireless network light.
When I put the old memory back in, it works fine.

Did I purchase the wrong memory? Or is it faulty memory? Or is there something else I need to do? Thanks

 

I think you mean SO-DIMM - it stands for "small outline dual in-line memory module"

To answer your question though. Here are a couple of things you can try.

1. Remove and re-seat the RAM just in case it wasn't all the way in, and make sure the grooves on the SODIMM match up.

2. In your laptop's BIOS, there may be an option to run a memory test. If so, trying running it with your original memory and with your new memory.

3. It could be bad RAM (known to happen) and might just need to be replaced by the store you bought it from.

From the looks of it the EEE PC does use 667MHz DDR2 and so that rules out incompatible RAM modules.

All the best!
