Hi, I was hopping you could give me a hint to fix my little problem. I have an old nx7300 with an Intel Celeron M430, an original charger (that was temporary fixed with tape) and no battery. X According to HP specs, I can update to the T7600 and I made sure to install the latest version of the bios. The chipset is a Mobile Intel 945GM Express Chipset with 667-MHz front side bus which is compatible with those processors. I have 2gb PC5300 inserted in one slot. The second slot is free. I purchased a T7200 and a T5600 processors to boost this old prick. Problem occurs with both of them actually. FYI I made sure the BIOS to be up-to-date with the latest version from HP support site. BIOS recognize the processors, activating specific options like virtualization and dual core. Once the BIOS sequence has completed, I have blank screen. Nothing's going on. When reversing to the Celeron, I can boot up windows or from CD. I have the feeling this is due to lower voltage maybe the consequence of the charger failure... ? thanks in advance for any help!!!
All that work on old Compaq why?
if the DC pack voltage is in spec then its ok.
a voltmeter tells you that easy, we, when lids off and at the internal jacks pins, under full load.
most laptops, had many processor choices, and up to 3 power packs matching that and up to 3 video cars, my HP5840w has that.
if BIOS screens are dead, you lost power, Im sure screen is ok)
BIOS most always work its resident in ROM and always works.
even with HDD /SSD removed.
its the acid test for all PCs.
this,Since the days of IBM PC Jr.... (with rom packs)
yes, older than dirt.
when changing processors
the new processor may have a new MMC
memory controller and needs its own
special memory sticks. DMM
each MMC by intel
has a set of organizational (called TOPO)rules
that can never be violated.
the Processor page it iNtel tells you those rules for the DMM 10x more better than at HP.
there are memory size limits
memory type
speed,
and topo rules (topological)
and more.
and memory size max totatl
and max per socket.
even min sizes...
does the HP manual (service) show your new processor as supported, im to lazy to look.
id have not done any of that!
why.
i'd SSD it, first,done many, vast... now.
if at all
SSD will make it scream.
try it.
ever think to look and ask first on a real forum.
i hang out here.
http://h30434.www3.hp.com/t5/Notebook-Ha...
the change may need a new mobo
new bios
new heatsink; even bigger fan.
new power supply; pack. higher watts.
or more.... ask .
after upgrading my 3, LT
one need the huge powersupply,
it sucks 100w,with fasted CPU and GPU
but flies.

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.

Eric,
There are a lot of factors that can be a cause to slow boot up times. Sometimes it is a lengthy process to figure out what or why the boot time takes so long.
In Windows XP the first step that I would perform is to click on Start>Run and then type: "msconfig" and click OK. (Don't put in the " marks.)
Once you are in the System Configuration Tool, click the Startup tab. Disable all of the items in that list. Then click the Services tab. Check the Box for "Hide all Microsoft Services" and then disable all.
After clicking "OK" you will be prompted to reboot the computer. Do so. Time the boot/startup time. If it has significantly improved, then half of the troubleshooting is done. Next, you will need to go back into MSCONFIG and go to the services tab and enable a few of the services. Then apply and reboot. Make sure to write down which services you've re-enabled and make sure to time your bootup.
Through the process of elimination, you should be able to find out which service is slowing the system down. If you have rechecked all of the services and the system is still booting with an acceptable speed, then begin checking the startup items. Do the same process of checking just a few items at a time, writing down which ones you are checking. After rechecking just a few, apply and reboot, timing the boot up time.
Through this process you should be able to find the services or startup items that are slowing your computer down. Once the offending services or startup items are identified, you will need to make a decision of whether to leave that item out of the startup process or possibly reinstall that program.
If you find the offending item, and are unable to identify it by name, you can always go to Google and type that item's name into the Google search and it may give you an indication for what that startup item is, or what it is part of.
Sometimes, if you have a virus or malware, you may find the items listed in startup. If you do find a suspicious item, then you will need to make sure to run a full malware scan to remove any of those items that are unwanted.
Hope this has helped steer in the right direction to find out why your computer is running so slowly!

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"

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."
