Intel Celeron CPU upgrade

[Timur]

Hello friends! Need your help.

I have an old laptop Acer TravelMate 2354LC. I want to upgrade its' CPU (yes, i know that it is an old model, but i need it).

Now there is: Intel Celeron M 350 (1,3 GHz, 400 MHz FSB, 1 MB L2 cache). I tried to choose the most among appliable variants from site "cpu-upgrade".

So i have bought Pentium M765 (2,1 GHz, 400 MHz FSB, 2 MB). But with this CPU my Laptop dosn't loads...

Please, tell if i had bought the wrong model and which one is the best for upgrading my old laptop. Thank you!
