Hey all,

The laptop is a Packard Bell LJ65.

I was thinking of upgrading my laptop CPU. From a Intel Core 2 Duo T6400 @ 2GHz with 800fsb.

To an Intel® Core™2 Quad Processor Q9100 2.26 GHz, 1066fsb. I think these are both the same P478 Socket.

I have an Intel PM45 motherboard, would the Quad CPU work on it?

Thanks guys.

So long as the socket is defiantly the same, and the TDP of the quad core doesnt exceed the t6400 by 25% you should be okay, although bear in mind there will be a certain loss in battery duration from the upgrade.

Personally i would tear down my laptop at least once in full, extract the cpu, and put it back in before i make any motives to commit to buying its replacement.
 
Thermal Design Power, basically the amount of watts the thing will eat, since most of those watts are then expelled as heat, This means that 1) maybe the cooling pipes wont be able to handle max load with this new CPU, and you might melt things, 2) but it also means your drawing that many more watts from the circuitry on the motherboard, which may stress it beyond its means electrically, OEM laptop makers dont build the parts with expansion and over-compensation in mind.
 
the quad core wont work, the one you quoted is for a desktop machine and the T6400 is a mobile chip.
EDIT:
however looking having a look on intels site i'd say your stuck to Core 2 Duo's and not i3/i5 or i7 chips as they are all different mobile sockets. You can get a T9900 which is a 3.06Ghz Core 2 Duo with 1066FSB link here -

only catch is it comes in two socket forms so you'd have to make sure which one your picking up.

how come you didnt go for a quad core laptop instead of having to transplant from core 2 duo to core quad? as its going to be expensive i'd have thought.
my mistake on the Q9200 its just i didnt see it on intels website.. saw a Q9100 and Q9000.
 
You can't put a quad in that machine that I'm aware. Best checking with a Packard Bell expert.

You'd likely be able to upgrade to a faster dual core Core 2 Duo of the same TDP as suggested above. Probably better buying a new laptop to be honest.

Click to expand...

At the time I couldn't afford it, and I've seen a Quad core for £144 on the bay. Do you guys think it's worth the upgrade? Or should I just stick it out with this?
 
I too am of the personal opinion that its darned expensive a course of action , sell your laptop on and buy a better one , or find a space for the second one in your life be it with a family member or friend,

Transplanting the Cpu although possible isnt advisable since you have no idea how **** the mobo is compatibility wise, maybe a quad just wont work, you really wont know until you try, and the reason for that is no matter how hard you google , you prob wont find a story of anyone else trying to do it with your model/brand...

I would try if i had money to burn, or a get out of jail free card and could send the cpu back after opening it, but without those options i'd not do what your attempting.
 
I agree. It's reliant on the BIOS support. Something like a ThinkPad W-series or a Dell Precision mobile workstation would have it, I doubt a Packard Bell with Intel onboard graphics would.
 
My Packard Bell doesn't have onboard graphics, it has a ATI 4570 512MB Graphics card. I did do a BIOS flash recently, to the latest one. I think the quad isn't a good idea as it is, well risky. As said before I won't know until I try.

Thanks for the replies though.
