Want To Upgrade My Acer 1830t Cpu

Hi People,
I am new to the site, so I am hoping to get some solid info on a new cpu upgrade. I have a Acer aspire 1830T-3721 with the intel i5-430um low 18 watts voltage cpu and a BGA1288 socket.
My question is what is the best and most powerfull intel i7 cpu can I use for an upgrade and can I go a little higher in watts like to a 25watt cpu.
I see several i7 with a BGA1288 socket but not sure which one would be the fastest.
I do know the aspire 1830T-68u118 is the next notebook up from mine so I think I can use the i7-680um cpu for sure but hoping for a faster cpu.
Can any one give me a good recommendation for a cpu.

Err if I'm not mistaken the ULV CPU is BGA soldered on...so there's no upgrading besides desoldering the CPU. The easiest way would be buying a new motherboard but that would hardly be worth it jumping from an ULV i5 to a ULV i7..

 

are you sure about that. I was under the impression that the cpu could be change . How can I find out for sure if it is possible to change or if it is soldered in like you say.
Is there a tech that can tell me or some way to tell as I dont have a service guide to check out the dismanteling of the unit. or me taking it apart myself would void my warranty.

 

Now, Tsuande might be wrong - but he is a 'tech' so he should know.

 

The reason why I highly suspect a BGA processor is almost all ULV processors are BGA soldered. Also thin notebooks use BGA as it is smaller form factor than PGA processors.

 

Thanks for your help. that makes a lot of sense.

 

Also If I had someone who would be able to do the work soldering the cpu in what would be the best cpu in the intel i7 that would work. Could I also upgrade to a little higher wattage from 18 to 25. Would this merely shorten the battery life.

 

You would need to find someone who does BGA work or a repair shop. You would also need to purchase a BGA processor.

The problem is the cooling system in your laptop is designated to do 18 watts and maybe a little head room for the i5 Turbo Boost. 25 watt is a pretty big jump for an ULV notebook, not to mention also decreasing your battery life. Worst case scenario is your notebook shuts down to prevent overheating.

Again, why do you want to upgrade to an i7? i7 only offer slightly faster out of the box speeds, higher turbo and slightly more cache. Unless you are rendering on an Acer Timeline (?!?!?!) then upgrading will likely not result in a faster computer. If you are looking for faster I/O, look to upgrade to a solid state drive.
