Upgrading memory on my Compaq Evo N400C notepad

I have a compaq notepad and everything says I have 256MB of memory installed in two slots. I have opened the bottom of the laptop and I find only a single slot with only a 128mb of ram installed. Does this notebook have memory somewhere else and how can I increase the ram on the notebook. Many regards David

2 EricCharles2:
It says the maximum for the N400c would be 512MB
Do you have 1 module of 1GB or 2 pieces of 512?
100 of 133 MHz?
Thanks for replying!

You probably have 128 mb inegrated on the motherboard. So to increase the ram you can probably only put one stick in the computer. Good luck finding the memory if this computer is over two years old.

Nope RAM is always stored in the same place. Always together in slots. To see the accurate RAM go into Control Panel and click on System Icon. It will give you RAM information. As far as upgrading it, if you found it then you can easily upgrade it. But you have to make sure you get the exact same type. DDR SDRAM matches, DDR SDRAM, and DDR2 must be with DDR2. This will also be in the System Window. As far as the max RAM you can hold you will have to go to the HP website, type in your model number and it will tell you the max. So if you have one slot then get 1GB. Hope this helps. Please rate accordingly.

Blue Screen of death


According to this link, the memory of Compaq Evo N610c can be upgradable to 1024 mb.

http://h18000.www1.hp.com/products/quickspecs/11382_div/11382_div.HTML

Memory Upgrade for Compaq Evo N610C, the Compaq Evo N610C takes the PC2100 DDR SDRAM SODIMMs Memory Type, and comes installed with of Memory. You can upgrade your Compaq Evo N610C to up to a maximum of 1.0 GB Memory, the system has 2 sockets to install Memory, already with standard Memory installed. For best system performance use the maximum amount of allowed Memory per slot for your system. (Souce: http://www.memorystock.com/memory/CompaqEvoN610C.html)

So you have to install 512mb memory module on each slot to make up 1024mb of memory.

Did you install 512mb memory module on each slot or did you just install 1GB memory module in one slot?

Try to go back to 256mb RAM and see if you will have the same blue screen error. If you did not receive any blue screen, try to add memory into it or just insert 512mb first and then oserve again if you will have the blue screen error.

You may also want to go to these links for other suggestions.

Compaq EVO N400C PC Notebook Problem brought new battery! fully charged all night! turn laptop on within one second the thing turns off! AC works fine! new battery! old laptop! what can i do, please help?


your laptop should function even without a battery. Remove the battery you just bought and see if only with AC adapter, would your laptop turn on?

If not, then try removing the memory and see using a pencil eraser, clean the contacts of the memory and see if you can power your laptop with only ac
