pcg-fr315b processor upgade

[madukan]

: I would like to upgrade the processor in my laptop, it currently has a celeron 2.6 installed, can i upgrade to a pentium 4 and if so which processors will fit, does it have to be a special mobile processor?
I believe the celeron fitted in this laptop is a desktop cpu, if i can change it to a mobile P4 will i have to change the cpu voltage, is this even possible. Any help or links to sites that can help with this would be appreciated.
I've upgraded/built many desktop puters so i'm not a total noob but I need some advice before I take a screwdriver to my precious laptop.
heres a link to the specs of my laptop

You must don't open the case!
Look at the Internet for tools.

Like SisSoftware Sandra or Everest Home Edition.

But I would not only change the CPU, better you change the RAM
(upgrate to 1GB)

Look at the manufacturer from the RAM in your Notebook (use EVEREST or Sandra) and use this to upgrate.

Changing the RAM is no problem(look at the compatiblity)
Changing the CPU, I don't know?

Seb's right

I've heard someone say they sucessfully upgraded the FR315B to the Intel (R) Core 2 Duo processor without any problems.  It apparently has the same pin interface. 

I'm looking to upgrade my FR31 myself, as I really love this laptop and Sony laptop these days seem to fall apart.  They don't make them like they used to 😞

Also if your laptop is running slow, and you have 1GB of Ram installed Windows 7 runs suprisingly well on the machine, faster than Windows XP suprisingly.  I love XP but Windows 7 (32-bit) runs really well on the old vaio.

PS: Are you saying that the Vaio PCG-FR315B uses a desktop processor rather than a laptop one?
