Yes you can, at least to 1 Gb maybe possibly to 2 Gb. There will be two memory slots in your laptop. To increase the RAM to 1 Gb install another 512 Mb RAM module in the empty 2nd memory slot. Make sure you use the same make and speed RAM as the one that is installed. If you have two 256 Mb RAM modules installed in your laptop then you need to replace the two 256 Mb RAM modules with two 512 Mb RAM modules to get a total of 1 Gb RAM.
The Thinkpad is installed with 128 MB SDRAM is standard, and is expandable to 512 MB
There are two memory slots, to expand it to 512 Mb you need two 256 Mb RAM modules and throw away the 128 Mb RAM module, but if you don't throw away this module and you insert a 256 Mb RAM module in the 2nd memory slot then your total memory would be 384 Mb.
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.
Toshiba Satellite 2405-S221 Laptop takes the PC2100 DDR SDRAM SODIMMs Memory Type, and comes installed with 256 MB (removable) of Memory. You can upgrade your Toshiba Satellite 2405-S221 Laptop to up to a maximum of 512 MB Memory, the system has 2 sockets to install Memory, already with 256 MB (removable) standard Memory installed.
In short.... yeah, 512k is the max.
Doesn't appear to a bios limitation. It is a hardware issue that is limiting the amount.
Specifications for the Compaq 12XL125 state that the system memory is:
64 MB 100 MHz SyncDRAM, shared memory architecture, upgradable to 192 MB - 4 MB dedicated for video memory This system will not be able to use the ram you are trying to install.

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
