I've been doing a few upgrades to my R50 1829-4AM and the last one I want to do is the CPU. It currently has the original Pentium M Centrino 1.4ghz installed and I've looked at the list available to the R50 suite in the link below to see what is available:
I was contemplating purchasing the Intel Pentium M processor 745 (1.8GHz) (FRU = 91P7357) and wanted to be sure that it was compatible with the laptop and that there would be no adverse issues (i.e. overheating)
Would I need to update any other components in-line with the CPU to make sure it all functions smoothly?
Thanks in advance

Just a few upgrades, nothing too major:
The RAM has been increased to 2gb.
The HDD has been upgraded to a Seagate Momentus 160gb.
The PCI Card has been upgraded to Lenovo ThinkPad 11a/b/g Wireless LAN Mini PCI Adapter II

Sorry, but you cannot upgrade to a Pentium M 745. Your chipset limits you to Pentium M processors but not the Pentium M 7XX series.
This information is direct from the HMM.
Intel Pentium M processor 1.4 GHz, L2 1-MB cache
Intel Pentium M processor 1.5 GHz, L2 1-MB cache
Intel Pentium M processor 1.6 GHz, L2 1-MB cache
Intel Pentium M processor 1.7 GHz, L2 1-MB cache

Thanks to both of you for your replies.
I did initially think I would be better off upgrading to the Intel Pentium M processor, 1.7GHz (FRU = 91P7387) rather than the Intel Pentium M processor 745 (1.8GHz) (FRU = 91P7357) but wanted to ask anyway.
The HDD I installed spins at 5400 rpm and has markedly improved performance as you suggested it would but I wanted to beef up the CPU a little more as well.
Thankfully I also own a T60 Core 2 Duo and the R50 is my second laptop. I can't bring myself around to get rid of it. It still runs like when I first bought it.
