Question about Sony VAIO PCG-K25 Notebook

Not recognizing new memory

Hi,

I have a Sony PCG-K25 laptop with 2x256m ram modules that are reading as 448m of total ram. I have replaced them with the proper (so the retailer says) 2x512m modules and they are still being read as 448m total. Can you help me with this? Thank you.

Mike

According to your laptop's specification it should support up to 1GB of RAM so it should read as 1GB if you installed a pair of 512MB of RAM.

When your computer starts(POST) if will show you the amount of memory that it could detect on your laptop, if it still reads 448***KB or something close to that the next step would be resetting the BIOS settings to factory. To perform this step you should read carefully the laptop's user guide or if you are hesitant try calling the tech support hotline for Sony.

Take them back out and re-seat them and try again. THe "Retailer" can very well be wrong. You may also need to tell the bios you upgraded, however that is highly unlikely. THe computer may not be able to handle 1gb of ram also, but thats unlikely also. I say it may all lead down to a bad stick of memory you bought from your "retailer"

I have a Sony Vaio PCG-K25 laptop and am trying to upgrade to a gig of memory. Is it possible to do this? I put 2 512 memory chips in the slots but it only sees 448. Using Kingston Technology 512 mb...


Hi,

This laptop has its own graphics card that doesn't rely on system memory for the graphics.

There should be no reason why its not detecting all 1GB of ram that you have installed.

Open the ram cover and make sure that you have clipped the ram into place properly.


Regards.

Change ram from 512 to 1 gig bios cannot read added ram


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.

I am trying to install new RAM on my mother's Sony VAIO PCG-K25 laptop. It had two slots, each with 256MB sticks in them. I replaced these with 512MB sticks, and the computer wouldn't boot. It wouldn't...


make sure they are compatible with your computer, there are alot of electronic stores (circuit city) was the worst at it, but will sell you the wrong ones and say they are backwards compatible.. usually P4 2.8 can run PC2700, some run PC2100, which im hoping yours is PC2700... if so, make sure they are NON-ECC also... i would just get 2 1 gig PC2700 DDR 200pin sticks and stick em in... good luck

My screen died on my Sony PCG-K25, but It works fine if I plug in a monitor


either your inverter went bad or your backlight did use a light and shine it down the screen at an angle if you can see anything then it's the ccfl(s) if it's totally black then it's probably the inverter which is better because it's easier to replace and costs about $15-$20 the ccfls go for around $15 but there are usually 2 and you have to dismantle the lcd and solder them to wires to replace them

Slow performance


System resources at 75% on idle only gives you 25% to work your notebook. Sony VAIO PCG-K25 Laptop 2.8 GHz Pentium 4, 512 MB RAM should be plenty to run most OS and programs. The OS, software and accessories attached to your laptop are utilizing 75% of your resources on startup. You may want to do some maintenance, check your processes on startup & carefully remove any not being used, check your networking usage, good antivirus & spyware cleaning, clean & defrag your hard drive, remove some of your files & programs,and upgrade your memory.

Just need to know how to change the ram in my Sony Vaio PCG-v505ap

You can do this in two ways: opening your notebook and taking a look on the memory modules already installed (we will explain more about this later) or running a program like Everest (available on our download section). We ran Everest (going to Motherboard, Chipset, Memory Slots) on our notebook and found that it was using two 256 MB DDR-SDRAM PC2700 (“DDR333”) modules, for a total of 512 MB.

Figure 1: Checking your current memory configuration with Everest.
If your notebook has an empty memory slot, just go to the computer store and buy a new SO-DIMM module with the same technology (SDRAM or DDR-SDRAM) and speed of any capacity you want – of course you need to know the capacity limit of your notebook. You cannot install a 1 GB module in a notebook that only accepts modules up to 512 MB, for example. Our notebook – a Sony Vaio PCG-V505ECP – accepts modules up to 1 GB, for a total of 2 GB RAM, since it has two memory slots.
For example, if your notebook has one 256 MB module and an empty memory slot, if you buy and install another 256 MB module, it will have 512 MB RAM. If you buy and install a 512 MB module, your notebook will have 768 MB.
If your notebook already has two memory modules, you will need to remove one of the installed modules in order to install the new one. If the two modules have the same capacity, it doesn’t matter which one you will take away, but if they have different capacities, remove the one with smaller capacity. The new RAM capacity of your notebook will be of the capacity of the remaining module plus the capacity of the new module.
In our case, our notebook has two 256 MB modules. So we will remove one of these modules and install a new one on its place. We bought a 1 GB-module, so after installing it our notebook will have 1,280 MB RAM installed (memory math is tricky, since 1 GB equals to 1,024 MB not 1,000; so 1,024 MB + 256 MB = 1,280 MB).
