HP DV5 Motherboard Part Number Supporting Intel T9600

[AltérEgo]

Hello,

Actually wanted to go to the archived community dicsussions, but those forums are locked and read only. So asking over here.

I have a long running HP Pavilion dv5t Entertainment Notebook (CTO) KQ574AV with the following specs

-  Intel(R) Core(TM)2 Duo Processor P7350 (2.0GHz)
- 15.4" diagonal WSXGA+ High-Definition HP BrightView Widescreen Display (1680 x 1050)

After serving faithfully , it recently died with the mishandling and water spillage by children, so it does not power on anymore, and the moment I press the power button, it turns off immediately.

So now I was looking for motherboard replacement and a processor upgrade . I already have a working Intel T9600 processor lying around. I have been thru partsurfer, but sometimes the information is not sufficient and I am not sure which compatible boards would support Intel T9600.

So is there anywhere where I can find a list of all compatible motherboard part numbers which will fit in this laptop casing, and will support T9600. Having an NVIDIA graphics is an added optional add on, so I can go for the plain vanilla intel graphics as well. 

Since I am resurrecting an old machine, being cost effective is a priority over here. 

If i have a couple of compatible T9600 support motherboard part numbers, maybe I can look search online for the lowest price option that would fulfill my intended purpose.

Would appreciate any guidance in the right direction.

Thanks.

Intel motherboards

T9600 is compatible with any of these:

Post back if you want any more help or please accept as solution if this is the info you needed.

Thanks for the response Huffer,

So it actually brings two questions.

1. I already have a 482870-001 with me which i got some time ago (not from Ebay). I tried seating it in the laptop housing and connecting all basic ribbons/connectors. I did pop in the T9600 and seated the heat sink tightly. However upon the startup the laptop was showing blank or no screen, in addition to caps and scroll lock lights blinking in sporadic manner. Sometimes both lights would blink 2 times and the machine turns off automatically, while sometimes it was 3 with the same behaviour. I am still unable to figure out whether it is a board problem or processor or BIOS. 

Is there any guide available about assemble/dismantling instructions officially from HP, so I can see if I am missing any essential connection . Or is there is way in such condition to check for BIOS corruption and recovery.

2. If I want to go for a lower price option, by letting go of the T9600 compatibility requirement. Can you please inform if 504642-001 DAQT6BMB6G0 can fit in the DV5 housing. I am not sure it would support T9600. Would it support P7350 (from my old burned board) or T3400. As I have all 3 processors pulled out from various machines in the past. 

Thanks for your time for any possible solutions and guidance.

I had to go to a 3rd party site to find the Manual and I cut and pasted that info about the system boards into the post. 

https://www.manualslib.com/manual/71803/Hp-Pavilion-Dv5.html?page=9#manual

All the motherboards that can fit in your chassis are listed there. The listed processors are T8400 T8600 T9400 T9600. If the P7350 was in a motherboard mounted in your chassis perhaps I have the wrong Manual. Why don't you try the P7350 into the  482870-001  board?

Actually I did try P7350 in 482870-001, but it resulted in the same caps + scroll lock blinking behavior. At that point I wasnt sure is it due to the board being bad (since the same board wasnt working with T9600) or is it because P7350 wasnt compatible with this board. So not much of a deduction I can draw over here.

Same confusion lies when I tried 482870-001 with T9600 and getting the blinking behavior. Since I guess it is very rare that processor might have gone bad, most of the chances are the motherboard isnt cooperating anymore. 

As I asked, is there a way to try the BIOS recovery for 482870-001 to give it is try before giving up on it. Wasn't able to find much guidance about it.

Not sure if you would be able to guide anything about 504642-001 and which processors it would support. 

Thanks for all the help.

That board is from the dv5-1200 series and must have been a later updated part number after issuance of the Manual so also should work with the T9600

Hello,

So well searching on partsurfer for board no 504642-001, i picked one of the available models which this board is used, being FX285AV  (HP PAVILION DV5-1247LA ). Browsing thru the part list I can see the motherboard number is mentioned 

And at the same time a number of processors are mentioned as below screenshot. 

1. So can I safely assume that this motherboard part number will work with all the listed processors ? without any limitation of any region or country or series specif variants of the same model.

It's as good a theory as any. Certainly the Core 2 Duos will work or should. The Celeron and Pentium generally are associated with a lesser chipset.
