Want to upgrade my HP TouchSmart IQ504 Desktop PC 2.0GHz processor for a 3.1 ghz ?

First, have you ever changed/upgraded a CPU? It take quite a bit of research to upgrage. If you look at this spec of the Mobo your options are very limited, The Mobo only supports 2 different type Processors, 1, Core 2 Duo (Merom); , 2 Core 2 Duo (Penryn): If you have a 64bit OS consider a memory upgrade, if you haven't already.

Best cpu upgrade

The Gateway MX8738 Notebook PC uses an Intel Pentium Dual Core Mobile T2060 processor.

{ Look under Specifications, and Components }

Yonah Core based.
Built on the 65 NanoMeter technology. (65nm)

Front Side Bus frequency rate is 533MHz. (FSB 'speed' = 533MHz)
Voltage range it can operate on is from .0762 Volts DC to 1.30 Volts DC

Uses the Socket M processor socket,

The motherboard chipset is an Intel 943GML for the Northbridge chip, and an Intel 82801GBM for the Southbridge chip.
(The Southbridge part number is Intel 82801GBM. It is also referred to as ICH7-M.
Also scroll down to the heading - Southbridge 9XX and 3/4 Series Chipsets. ICH7-M ),

Bookmark the above chart, I'll be referring back to it.

This is a motherboard diagram for the technology used for your motherboard, in the Gateway MX8738 Notebook PC,


The motherboard chipset technology used in your laptop is a Northbridge chip, and a Southbridge chip.
(Does not apply to motherboards that support the Intel Core i3, Core i5, Core i7, and Core i9 processors)

The Northbridge chip handles the faster capabilities of a computer.
Supports the Processor, Ram Memory, and High-speed graphics.

[ High-speed graphics being AGP and PCI-Express.
Does Not apply to anything connected to the PCI bus, or Integrated Graphics.
These are slower processes of a computer, and are handled by the Southbridge chip ]

The Southbridge chip handles the slower capabilities of a computer;
Anything to do with the IDE bus, SATA bus, USB bus, Ethernet, and Audio. (Sound)

Therefore you want to look first of all at what processor socket it has, what processor was already installed, and what the Northbridge chip is.

1) Socket M processor socket.
Your replacement processor has to fit in a Socket M processor socket.

2) You know that your BIOS supports an Intel Dual Core processor, and the Yonah Core technology.
The replacement processor has to have a 533MegaHertz Front Side Bus. (533MHz FSB)
Has to operate with .0762 to 1.30 Volts (DC)

3) The Northbridge chip is an Intel 943GML.
Looking at the chart you can see this Northbridge chip will support;

A) Celeron M (Eeech!)
B) Core Solo (Bleech!)
C) Pentium Dual Core

In the list the Pentium Dual Core is the best option.
{ The Celeron M has HALF of the L2 cache that a comparable Pentium M would have.
The Core Solo is just a glorified Pentium 4. It's a Single core processor }

Has to be a mobile Pentium Dual Core that uses a 533MHz FSB.

Based on the Voltage, FSB, and processor socket used (Socket M), the Intel Pentium Dual Core
model T2130, is the best processor your motherboard will support.

What are we talking about here?
You would be going from a processor that operates at a maximum frequency rate of 1.60GigaHertz, to a processor that operates at a maximum frequency rate ('Speed') of 1.87GHz.

Not enough of a performance boost to waste your hard earned money, or time on, IMHO.

My Wifi is not working. My laptop sound is scratchy. I want to upgrade my processor from celeron to core 2 duo which one i should select for cpu upgrade?

Two main things to know before you can attempt a Processor upgrade.

1) What Processor socket is on the motherboard?

2) What motherboard chipset is on the motherboard?
(Northbridge and Southbridge chip. Unless it's a motherboard that supports Intel Core 13, Core i5, Core i7, and Core i9 processors)

According to specifications I found online just now, the BenQ Joybook A53 comes with an,
Intel Core2 Duo T7250 processor,

Scroll down.

(Only 512MB's of DDR2 Sdram (SO-DIMM) ram memory that operates at 667Megahertz?
{ PC2-5300} Yecch! You need at LEAST 1GB of ram memory. (512MB + 512MB = 1GB.
2GB would be best)

Information on the Intel mobile Core2 Duo T7250 processor,

Scroll the page down until in the left column you see T7250. Then read across, and match the headings above.

Uses a Socket M processor socket,

Is your problem directed to a BenQ Joybook A53 Notebook PC, or is it another model?

IBM ThinkPad R40 Intel Centrino Upgrade to Intel Core 2 Duo?

According to system specs your system is not compatible with the Core 2 Duo or Centrino Core 2 Duo. To upgrade to those chips you would need to replace the motherboard with one capable of running those chips. If you decided to do that you would almost surely need new RAM as newer boards use newer technology. By the time you did this the upgrade would not be cost effective. Hope this helps & please remember to rate my answer. Thanks.
