CPU upgrade for HP530

Hello, I am new here, so please for give me, if I post this in the wrong space,,,,

I own an old HP530 laptop for travelling and I would like to replace the CPU if possible.
I have upped the RAM to 2GB and replaced the HDD with an SSD, and it now runs a reasonable speed on a Win7 32bit

According to Speccy there is now an Intel Celeron M 520 @ 1.60GHz inside, with a 479 Socket on an
HP Motherboard 30D5 (U10) with the Chipset Satz i945GME, and a Southbridge Modell 82801GHM (ICH7-M/U)
with the HP BIOS 68MVU Version F 06 vom Dez 2007


What is my best choice? The information on the internet is confusing, but points to a T7200....?

Thanks, TM

 

If both Speecy and CPU-Z report i945GME then it's almost certain that your HP uses 945GM chipset, and yes you can go for Core 2 Duo T7200/T7400/T7600 no problem. T7200 only costs a few bucks so doesn't hurt if you still plans on using it.

Make sure your laptop has the latest BIOS before putting your new CPU, just to be safe.

P.S. HP 530 has two motherboard options: one with 945GM chipset (the normal one); one with 940GML chipset which appears in most Yonah Celeron (4x0) models.

The 940GML chipset only supports single core Yonah (i.e. Celeron 4x0 and Core Solo, and they're 32-bit only), but since your laptop already has the Merom Celeron (64-bit capable and newer), there's no way it has the dreaded low-end chipset.

 

Thanks, no its definately a 945. I bought it about12 years ago without an OS and I still have the e.mails from HP explaining the drivers for it.
The T7200 are around, but not too many of them...
One more question, so I really simply have to put the new chip into socket, or does it have to somehow get "glued" or whatever?

Someone actually send me YouTube Video how to replace it, the video is really hilarious, If you wanna have a good laugh:



Thanks

 

The CPU in HP 530 is socketed so you just need to disassemble the laptop, remove the old CPU (the socket has a locking mechanism, use a flathead screwdriver to unlock it), clean the fan and heatsink, put your new CPU (don't forget to apply a bit of thermal paste onto the new CPU's die) and lock the socket, put the parts back together and it's done.

While it's possible to remove the base without taking the whole thing apart (there's no screws under the keyboard), you have to be careful when you close the lid after removing the post screws that secures the hinges to the base, as the screen assembly will be solely supported by a few shorter screws and the palmrest by then. Just a bit of force can dislodge the nuts and it's a PITA to secure them back into right position (needs something like epoxy glue).

 

Thanks, that is precisely what I was asking:

"...put your new CPU (don't forget to apply a bit of thermal paste onto the new CPU's die)..."

What is a thermal paste, where do I get it, and exactly where do I put it?

 

Thermal paste acts as the medium to transfer heat from the CPU to the heatsink, moreover it fills the gap between the CPU and the heatsink, the surfaces aren't totally smooth despite their looks.

This is what thermal paste is, and how it should be applied:

Put some thermal paste on the CPU (about the size of a pea, slightly less for a mobile CPU since contact area is smaller, you don't need too much) and put the heatsink back, that's it, the heatsink will press the paste and spread it over the surface. Optionally you can spread it over the the surface of the CPU with a credit card, that way you can make sure it's enough to cover the whole surface.

 

Thank you very much
