My nx7300 can't boot up after processor upgrade

SOURCE: Hp 530 notebook cpu upgrade

It's not posible to upgrade to a dual core, the motherboard is a different design. Keep in mind that the processor, motherboard and memory have a matched frequency. If the processor doesn't match the board then it won't recognize it. Since the board does recognize the T2300, it may be that you need to match the memory in order to get it to boot. Match the memory by going to patriotmem.com and entering the model that the T2300 came from, it will tell you the memory frequency. If the memory matches the processor simply will not work with that board.

you can check below website if you wanna buy branded one.

And if you wanna buy china assembled one the you can check out in the market because such types products do not have exact price in market so.

Thank you,

You bios versions start at f.03,f.04,f.05, f.07, f.08,,,

The date and version that you posted does not match and bios version for your model.

The only reason you update a bios is if it falls under the problems
listed for the new bios to correct.

Say your lap came with f.05, the only reason you would update to f.07 is because you had a graphic error,that the new update fixed.


The link below is the page for your drivers, if you look at bios,it shows the newest,if you click on version,you will see all the ones
that where made.

You should double check to make sure that you have the right bios version.

It is working.

Tested first with one new module with 2GB RAM, then with 2 modules, 2GB (new) + 1GB (original). Post and Windows are showing 3GB.
The HP 530 notebook is working OK.

I don't agree with John.

The Intel 945GM/GME Mobile motherboard chipset, DOES indeed support dual core processors;

[Dual Core means two Processor cores on a single-die chip.
TWO processors
Dual Channel? That is a statement for Ram Memory.

When a motherboard supports ram memory in a dual channel configuration,
two LIKE ram memory modules ('Stick') 'piggyback' off of each other.

They team up on the task/s at hand.

This was always thought to be the way to go. Run ram memory in a dual channel configuration, IF the motherboard supported it.

Supposed to vastly increase the 'speed' of the ram memory.
Purported to increase by up to 30 percent.

This has been found out to be 'Bunk' by a reputable website.
Tom's Hardware.
The actual increase is more like 1 to 2 percent!

Why do gamers, and those who want the MOST out of their system, use this? EVERY little bit helps! lol! ]


A quote from the HP Support Service Manual,

"The HP Compaq nx7300 and nx7400 Notebook PC offers advanced modularity, Intel Core Duo, Core Solo, Celeron, and Celeron M processors, and extensive multimedia support"

Said statement about processor support, is supported by;

(945GM/E in the left column.
The E stands for Express. It is an Intel 945GM Express chipset )

Uses the Socket M processor socket also.

The Intel Core 2 Duo T7200 mobile processor, operates in a voltage range of

Also uses a Socket M processor socket.

BIOS should recognize either one of the replacement processors.
I wonder though, if the latest BIOS update was the wrong way to go, however.

Hmmmm, let's see,.........

The current version is;
HPQFlash for HP Notebook System BIOS (68YGU) Microsoft Windows Vista based. Date: 27 Aug 2008. (Previous version 25 Jul 2007 )
[Description: 68YGU family ROM ]

Windows XP Home Edition, and Windows XP Pro Edition, use the same current BIOS update.

Did you make a backup of the old BIOS version? You may need to revert back to it. (Thinking is that you upgraded BIOS, before physically trying out either one of the replacement processors. The current version may not work )

However in your post that BIOS has recognized BOTH, of the replacement Processors, I agree with your thinking that the AC adapter, may not be putting out the full needed voltage. (Forget about the Amperage for now)

Following this line of thinking, (And a primer);

Power is always present to the laptop. Either with the Battery installed, or the AC adapter (Charger) connected. (And it's connected to power)
There is a 5 Volt Standby power present.

You press the Power On button. This temporarily closes the Power On switch underneath it.
This action starts the power supply circuit.

The first chipset to receive power is the BIOS chipset.
BIOS looks to see what devices are installed, does a Ram Memory count, TURNS the Processor ON, and then hands the computer (Notebook) over to the operating system.

BIOS recognized both replacement Processors. Assume it did a Ram Memory count, but when BIOS went to turn the Processor on, there wasn't enough power.

Do you have a multimeter, or access to one?
If not an economical model, can be purchased for as little as $8 to $12.
(Least here in the States it can)
Analog or digital is fine.

Multimeter set to DC Voltage, perform a voltage test of the AC adapter.

[ The multimeter has two port connections for it's leads.
The red port hole is for the Positive (red) probe lead.
The black port hole is for the Negative (black) probe lead.

Function Knob in the middle is set to DC Voltage.
If just a symbol, set it to the dotted line over a solid line symbol.
If there are two, or more scales, set the Function Knob to the
0 - 50 Volt (DC ) scale.

The port on the laptop that the AC adapter plugs into, is the DC Power Jack.
May be marked as DC IN.

The plug from the AC adapter that plugs into the DC Power Jack, has a center hole, and an outside cylindrical metal shell.

The center hole is POSITIVE.
The outside cylindrical metal shell is NEGATIVE.
You are looking for 18.5 Volts. (DC)

Appreciate it if you would post back your findings in a Comment.
Would also like to know, if I may, if you are SURE about the condition of the two Processors. Sure these babies are okay?

Testimonial: "Hi Joecoolvette! thanks so much for the time you dedicated. I will reverse the BIOS in the week end and see what's going. I'll check on monday at work with a multimeter. If I disable dual core option in the BIOS, then the computer boots up... I've read on a polish forum that HP installed by default Celeron M on defective mother boards which couldn't handle dual core. I will let you know for sure. I afraid we can't get round this problem. Thanks, Yael."
