Changing the CPU from my laptop?

BGA means Ball-Grid-Array. This means the CPU is soldered on to the motherboard and cannot be removed. Which means you can't upgrade.

So how come we found many of those CPU (socket BGA956) for sale if they are originally soldered?

The CPU comes soldered to the motherboard. So if you want a new CPU, you will have to buy the whole motherboard.

I am so disappointed of their doings seriously. Ok, so now, where can i find these mobos?  

Hello my name is Jeffrey and I work for ASUS Customer Loyalty Team

If you have the right equipment you can change the cpu or you can take it to a technician and have them change it. They will have to heat up that one area of the CPU and remove it carefully then they will have to get the new CPU and put that one on without getting and solder bridges. Once that is done you have to test the motherboard to make sure that they have not lost any of the other small components and that there are no compatibility issues.

The best thing to do is to purchase a motherboard with the specs that you are looking for. Laptop were not meant to be upgraded that's is why they have desktops so you can load it up with everything your heart desires.

Might be even cheaper just to get a new laptop. These days laptops are pretty affordable.

Sounds good! Thanks Jeffrey!

Can I contact them in forwarding your message?

Laptops are very cheap, but not compact ones. I have been lucky in purchasing this UL20A (that i consider compact) very cheap, because i stick to Asus laptop since 3 years 1/2, so regarding compact laptops below 13" and equipped with Core2Duo CPU's of +2Ghz, the price goes very high quite easily.

I am only targeting reliability of the mobo. (Asus is known for that), and the CPU specs, as for graphics i use an external graphic card extension device.
