Can I Upgrade To An Intel Pentium M ?

I have a Toshiba Satellite A105-S2194 laptop with a 1.73 Ghz Intel Celeron M 430 with socket 479 mPGA , i want to upgrade to a Pentium M http://processorfinder.intel.com/details.aspx?sSpec=sl77P but am not quite sure if its compatable since its a 3.06 Ghz, and if i would need to buy a new fan/heatsink for my laptop since the Pentium M Thermal Design Power is 70 w and the celeron is only 27 W. what heatsink/fan would any of you recommend if i do indeed need to replace it?

Motherboard - ATI
Model - SB450 Rev0.4b
Chipset - ATi RS400/RC400/RC410
Southbridge - SB400
with BIOS: Phoenix Technologies LTD 5.60 09/30/2008

any help regarding this issue would be greatly appreciated

*also i use my laptop as a desktop pretty much since its always plugged in and i hardly ever ever move it but thx ronnieb

*thx soo much everyone i almost bought that cpu off ebay just the other night but since im really really not good at this kind of stuff i thought id seek help from profesionals. If anyone could help me find a decent cpu maybe 2ghz and up, that would work with my laptop and any heatsinks/fans i would possibly need . i'd be forever thankful i do lots of gaming on this laptop aswell, i know its not the best out there but so far it exceeds my expectations sumtimes so a lil boost in performance would be rlly great last thing to upgrade on here is the cpu, ive upgraded to the max ram 2gb and 7200rpm HDD so only thing else i can think of to boost performance is the cpu. thx in advance

*heres more info from cpu z if this can help

Do not upgrade to the pentium 4 line up, as your battery life will get raped.

Stick with the Pentium M series

 

Your laptop can be upgraded to the Centrino processors, up to the Pentium M 780 @2.26Ghz.

The Pentium 4-M that you listed is designed for a different series and is based on the socket 478 desktop chips.

I'd take a look at a Pentium M 760 personally, best cost/performance ratio.

If you need any help, let me know

 

TO OP:

Pentium M and "Mobile Pentium 4" is not the same thing..

Pentium M is these

Mobile Pentium 4 is these

http://www.intel.com/products/processor_number/chart/mobile_pentium4.htm

Nevertheless, I dont know how, or why you would upgrade the processor.

I just got a refurbished off-lease dell laptop from "dell financial services" for $250 shipped.

It had Pentium M 1.6GHz 512MB ram, 40gb HD and a dvd/cd-rom.

It actually has amazing battery life, I got as much as 3 1/2 hours out of it!!

So I would suggest buying a new one, or looking for deals on old ones like I got.

Although if your components are all ok otherwise, and you feel a Pentium M processor will handle your work, then for the $20 or $30 the cpu costs its probably worth doing.

Btw according to cpubenchmark.net the pentium M line does not really perform any better in their tests then the celeron M line, although I dont know what kind of tests they run..

Folks, the Celeron 430 is a Socket M processor. You can't put Pentium 4 or Pentium M chips in there. I'm not too sure about the ATI chipset he's got there, but I'd venture it's full-featured enough to take Socket M Core Duo and Core 2 Duo processors up through the T7600.

 

You definitely cant upgrade to a 3.06Ghz Pentium 4 desktop mobile chip
Its a completely different socket
Pentium M's also will not fit cause his laptop is a socket M laptop

You should be able to upgrade to a socket M core duo or a core 2 duo.
I dont know what the ATi chipset can do though.
You should be fine with all core duo's up to the T2700, but I dont know if a core 2 duo will work

OP, please disregard posts 2-4, they are false.

Did a Google search... brought me right back to NBR:

You can use a T7600 as described in post 7 and 8.

Just make sure you have BIOS v5.9 according to post 7.

 

Sorry, thought it was a 479 at first.

Should be ok up to the T2450 in that case, I had a A135 (same Radeon 200M chipset), would not accept the 667 FSB processors.

 

Actually, that may not be totally correct. I didn't realize that different versions of the A105 have different chipsets (what a crappy naming scheme). There IS even a version (albeit not the one OP has) that has a Pentium M motherboard. ComputerMD82 may be right in that he can only go up to the T2450.

 

The A105-S2xxx have Radeon 200m Chipsets while the A105-S4xxx have Intel 945GM chipsets.

If I'm not mistaken it's limited to 533mhz FSB chips.

 

I'm not even sure THAT is entirely right... here's a 2716 with a Pentium M 740 XD

http://reviews.cnet.com/laptops/toshiba-satellite-a105-s2716/4505-3121_7-31660101.html

... but the 2194 definitely has the 200M.

 

Yep, that one has the 915GM chipset.. Way to go Toshiba!.... You never know what you'll find with them lol

 

i've been comparing between my celeron M toshiba and my pentium M toshiba, and the difference is huge in day to day computing. The pentium has way better performance and battery life.

 

A105-S1xxx – Radeon Xpress 200M Chipset
A105-S20xx – Radeon Xpress 200M Chipset
A105-S21xx – Radeon Xpress 200M Chipset
A105-S22xx – Radeon Xpress 200M Chipset
A105-S27xx – Intel 915GM Chipset
A105-S3xxx – Intel 915GM Chipset
A105-S4xxx – Intel 945GM Chipset

 

upgrade guide in my sig.

 

I can verify that the T2450 works in the A105-S2194. As that is what I am running in mine. Swapped it out, it booted up with a new option in the bios to enable or disable dynamic speed. I am running Bios version 5.60 which is the latest version I've found on the Toshiba site. As a side note, my wife has a A105-S2236 which uses exactly the same bios file and it has a Celeron 520 which has the EM64T support. So, should theoretically be possible to run a Core 2 Duo up to maybe the T5300. As far as the bus speed, I chose to play it safe and stick with a processor that is 533Mhz and figured the Core Duo at 2Ghz would be better for me than the Core 2 Duo at 1.73Ghz.

My machine:
A105-S2194
T2450 Core Duo @ 2GHz
2Gb Ram
500Gb Hard Drive
