Hey guys, I might have either made the smartest move today or the dumbest. My laptop is a Toshiba Tecra S1 which comes with the centrino 1.4ghz cpu. (Banias, 1mb L2 cache, 130nm). The chipset is an Intel i855pm with an ICH4-M southbridge. My laptop runs at 400fsb and support ddr333 (pc2700). The laptop has a stand alone Ati Radeon 9000 video card with dedicated 32mb. I have 1024ram.

The cpu that I stumbled across is an the Pentium 755 which is a centrino running at 2.0ghz, 2mb L2 cache, Dothan, 90nm and 400fsb. Ive checked and doubled check and found out that my chipset (northbridge\southbridge) are both fully compatible with this newer cpu. Also the newer models of my laptop (still the Tecra S1) ships with the same cpu as the one I stumbled across (centrino 2ghz, 400fsb cpu). Do you guys think I have to worry about anything? The only concern I had was the the Pentium 755 cpu will take more power but infact it takes less dude to the 90nm technology. I am quite knowledgable about computers, even with laptops but I'm still a little nervous about this move. Thanks ahead for your inputs :)

You will probably be ok.
I would think that the 2.0GHz Dothan is going to use even less power than your 1.4GHz Banias.
The only thing I would worry about is getting a BIOS that support the new CPU, or even worst that the new Tecra S1 comes with a new revision of the same MB.
P.S. I had a Asus 7400 laptop before that wouldn't accept CPU upgrade because I was told by ASUS only the 7400 Rev. B allows CPU upgrade.

Would it be possible to call/email Toshiba and ask if the hardware supports it?
