http://www.fixya.com/support/t18040647-cpu_upgrade(Last time I looked, this was the world's largest product support website, and there ARE technicians from AROUND the world; on here!!!!!!!! Do we count as an 'IT techie'? ........Lol!)
In all three of your posts, not once has the laptop manufacturer name, and model number been stated.
Processor (CPU) support depends on;
A) What processor socket is on the motherboard?
B) What motherboard chipset does the motherboard use?
C) What is the processor that is installed now?
With these parameters known, THEN you can think about CPU (Processor) upgrade.
1) CPU (Processor) has to FIT, the processor socket being used.
THIS, is also IF the motherboard HAS a processor socket; and is NOT soldered directly to the motherboard.
2) The motherboard chipset supports the Processor (CPU)
It has to be known if the motherboard chipset will support, the CPU (Processor) that you want to upgrade to.
For older computers the motherboard chipset consists of;
A) Northbridge chip
2) Southbridge chip
http://en.wikipedia.org/wiki/File:Motherboard_diagram.svgWith this technology the Northbridge chip, of the motherboard chipset; is what determines Processor (CPU) support.
Newer technology, such as used per se by the Intel Core i processors, does NOT use a Northbridge chip.
3) Looking at the existing Processor now, you can determine;
A) Voltage Range: What voltage range does the exisiting Processor use now?
Does the upgrade Processor also fall within this Voltage Range?
B) Core technology, and architecture:
Example:
Existing Processor uses the Conroe Core technology, and the 90nm architecture. (NanoMeter)
Does the upgrade Processor also use the same Core technology, and architecture?
If not is there a BIOS upgrade available?
(The motherboard chipset also comes into play again, here)
Enough of this generic prattle.........
Post the laptop manufacturer name, and model number.
Then I, or someone else can give you the facts; and not generic information.
Post back in a Comment.
