My computer is Acer Aspire 7250-0672. I have an AMD Dual-Core Processor E450. I want to find out if it's possible to upgrade it. If yes, what processor can I replace it with?

@DustinG. Wrong model. That topic is for the 7520, while the OP has a 7250. –  Indrek May 20 '12 at 16:19

For your viewing pleasure... enter image description here ... this is the socket for an Intel Core i7-3820qm. That's a mobile processor. Oh, and that's a laptop motherboard there.

So, as you can plainly see, new and current generation processors can be replaced.

The issue you will have, is one of whether or not the BIOS has been written to recognize the processor you want to replace your existing one with.... and of course, whether the processor you want will even work in the existing socket. Now, you might ask... why would a BIOS not recognize every processor put into the computer... or why a BIOS wouldn't be written ahead of time to just recognize every existing processor? Well, there are multiple reasons for that.

  1. Laptop manufacturers are in the business of selling laptops. Making their laptops upgradable means they sell fewer laptops.

  2. It's hard to write a BIOS to recognize a processor that doesn't exist yet.

You cannot apply the same logic that fits a Desktop BIOS and how they are regularly updated, with a laptop BIOS. Two different economic models attached to the reasoning behind the why.

What you need to do is find somewhere that sells replacement motherboards for your model Acer, and examine one. If it has a socket, you can replace your processor. If it doesn't have a socket, then your processor is probably soldered on.

The E-450 is soldered on. cpu-world.com/CPUs/Bobcat/AMD-E%20Series%20E-450.html –  DanteTheEgregore Nov 6 '13 at 13:52

From a little research I've found that the AMD E-series APUs, like most low-voltage CPUs, are soldered directly to the motherboard, rather than socketed. That means that you cannot upgrade the processor.

Source: AMD E-450 APU specifications
Note the socket is listed as "FT1 BGA". BGA stands for Ball Grid Array, which is a technology used for soldering integrated circuits (like a processor) to circuit boards (like a computer motherboard).

Also, and perhaps more importantly, you already have the fastest processor your system will support, so even if you could upgrade it, there'd be nothing to upgrade to.

Well from my own previous experiences, it depends on whether there is a socket for your processor or not.

I had two laptops, a Dell Latitude D620 and a MacBook Pro, and I have disassembled both. The D620 have its Core Duo T2300E processor sitting on a ZIF socket and the MacBook Pro have its i7-2620M soldered on.

The first means that I can swap a compatible processor, probably a Core 2 Duo, into the Latitude and give it some extra computing power and 64-bit capabilities. The latter meant that I hit the dead end on the MacBook Pro, and I cannot make a processor upgrade without buying a new computer.

In general it is possible to upgrade the processor of a laptop. As long as the CPU isn't soldered onto the motherboard you should be able to.

The processor is directly soldered on the PCB ... Have you ever opened a new generation laptop ? –  aleroot May 20 '12 at 14:41

@aleroot: This might be true for netbooks or ultrabooks but not for every modern laptop. –  Gurken Papst May 20 '12 at 17:46
    
@aleroot: However in this specific case you are probably right, as I a can only find references to BGA versions of this CPU. –  Gurken Papst May 20 '12 at 17:55
    
I got 2 downvotes but finally i was right ... :-) –  aleroot May 20 '12 at 18:21
    
@aleroot You're not right because you never answered the OP's question. You only made blanket statements, which were (and still are) incorrect. –  Indrek May 21 '12 at 9:32
