I installed new memory cards to upgrade my dell c640 ram from 512 mb to1 gb (2 512 mb cards). However I have not been able to update my BIOS to complete the upgrade. My BIOS needs to be reset to reflect the upgrade but I cannot navigate in my BIOS past the area to change the date. Please advise

Re: Update BIOS for memory upgrade
You cannot change the memory settings in BIOS. All you need to do is go into the bios screen. confim that it has seen your new memory and "save and exit" If it is not showing your new memory try removing and reinstalling the memory confirming it is installed correctly. it should just see it.

What type of RAM is your Pc using? SDR, DDR1 or DDR2? 1 GB single module of RAM maight be heavier for your notepad and the Laptop maight even fail to boot. Just use the 2 Modules of Ram (2 chips each 512MB) and check in BIOS if the RAM capacity has acually changed.
The original 2 sticks of 256 Mb of RAM gives you a total of 512
Mb of RAM. Two 512 Mb of RAM gives you a total of 1 Gb of RAM.
With two sticks of 512 Mb of RAM are you sure you got a total of 192 Mb of RAM, this is a lot less than the original RAM total of 512 Mb?
Should this be 1920 Mb of RAM?
If this 192 Mb is correct then the RAM modules are either not compatible with the laptop or if the RAM modules are not from the same manufacturer then they may not work together.
Most laptops have video cards that use part of the main RAM for video RAM, that is why the available RAM is less than the installed RAM modules. The amount of RAM the video card grabs depends upon the type of video card and in some cases the amount of video RAM can controlled in the BIOS setting.
Hi, Memory Upgrade for Sony VAIO
PCG-K35 Laptop, the Sony VAIO PCG-K35 Laptop takes the PC2100 DDR SDRAM
SODIMMs Memory Type, and comes installed with 512 MB = 256 MB
(removable) + 256 MB (removable) of Memory. You can upgrade your
Sony VAIO PCG-K35 Laptop to up to a maximum of 1.0 GB Memory, the
system has 2 sockets to install Memory, already with 512 MB = 256 MB
(removable) + 256 MB (removable) standard Memory installed. For best
Laptop performance use the maximum amount of allowed Memory per slot
for your Laptop.
There is nothing wrong and your install is OK.
The laptop has used some of the RAM as video RAM for the video card that is part of the motherboard.
You should have noticed that with a single 512Mb RAM you would not have the full 512Mb RAM available to you, the video has grabbed 128Mb of RAM.
There are two slots for memory on that laptop and it will take a maximum of 2GB of RAM. The memory type is
1.8-V SODIMM DDR-2. The cover ont he bottom if the laptop is easy to access and add more memory.
I had the same problem. I tried several brands of memory unsuccessfully, though they all guaranteed that their products would work with my machine. Finally, my brother (who works in IT) recommended that I go through The Upgrade Place (http://www.theupgradeplace.com/). Great price - less than half of what Dell charges - and the memory worked immediately upon installation.
When I told them that I had a Dell Inspiron 1100 laptop, they said that my PC required proprietary memory (which is true). I paid with a credit card and received the part two days later.
RAM - 512 MB (installed) upgradable upto 2 GB (max)DDR 2 SDRAM ( 1 x 512 MB ) that means your laptop has only 1 slot for memory.. ____________________________________________________ Was this solution helpful .Show your appreciation by rating it. dilipbagdi - Technical Associate
As the computer boots, it detects the additional memory and automatically updates the system configuration information
where did you get the memory?
If it is in properly and does't work,it is either bad or the wrong part number for your Dell C610
