I wish to install new Memory slot in my sony laptop VGN-A417M, Where is it situated in my laptop and how do I get into it. Thank you

You should not change this. Laptops have small video chips and often depend on "shared" memory to achieve good performance without overheating. Basically, the video processor borrows some of your installed RAM memory. Also, your laptop may have been supplied to you with less total RAM memory than the maximum and you can add more memory. In Windows, click on Start then right-click on Computer and select Properties. In the Properties window you can read how much total memory is installed. 2GB (2048MB) is a desrirable amount for Windows XP. Windows Vista and Windows 7 can benefit by having total 4GB of RAM memory. Check your Sony user manual for instructions on adding more memory. Basically, you turn off the laptop, remove the battery pack and unscrew a small cover on the bottom of the laptop to access the memory slots. Usually, there are 2 slots here. Ideally, you should install a matched pair of memory modules (a "kit") for peak performance. However, quantity of memory is more important than having matched modules, so if one slot is occupied and the other slot is empty you may simply buy one more module and install it in the empty slot.

LOL, what kind of laptop? I'll bet the bank it's a Sony Vaio. OK, even if i'm wrong some manufacturers didn't put much thought process on ease of access on certain components. Your 2nd memory slot is probably either under the keyboard or under the palmrest either to the left or right of the touch pad area. That means you'll have to do a partial disassemble to get to it.

The second slot is under the keyboard. There are three small clips at the front of the keyboard. You can release them with a small screw driver.

Please refer 123 page of this doc

remove the memorys and check the memory slots for any damaged pins .test the memory one by one on 2 slots(power off place one memory on slot1 and power on then do that procedure on slot2 ) if the laptop boot, one memory or one slots have problem and you can work with another one ,if you didnt see the boot screen at all try to reset the Bios .
if still dont work have to repair or replace the mainboard.

Second memory slot is under the keyboard. If you use link below and select 'user guide', then go to page 148 and it gives you detailed instructions on how to access the second memory.

I would appreciate feedback if this is useful. Thanks

Yes it is really plug into slot and use but it won't work at all if you won't install drivers. So please go to Sony's website and choose your model there and then download n install drivers. Thats it. Simple or not ?

Some Vaio laptops (and some HP's) have a memory slot under the keyboard.

The Crucial website suggests you can put 1GB in each slot. http://www.crucial.com/uk/store/listparts.aspx?model=VAIO%20VGN-S460%20Series Sony might know which CPUs will work with this. Hopefully any Pentium-M with 533 FSB.
