Upgrade dv2035us from T2050 to T5600?

Can anyone think of a reason why this wouldn't work? Page 5-86 of the service guide lists it as an option for dv2200 models, so I just want to make sure there's not a chipset or other hardware limitation with the early revision dv2000t's that would prevent me from swapping in a Merom core. I just want a cheap 64-bit capable CPU for the dv2035us I'm planning on refurbishing. I want to upgrade it to 4GB RAM and put 64-bit Vista on it, if the machine is agreeable. First thing I'll do is upgrade the BIOS of course. I'm more familiar with AMD than Intel so a sanity check would be appreciated.

 

Have you checked out the Intel Mobile Processor Compatibility Guide? It's a decent start at least. Beyond that I don't really know. You could ask HP.

What chipset and revision? (cpu-z)

You might wanna try 4gb ram first before the cpu

 

I don't think the T2050 is compatible with 64 bit OSs, hence, the upgrade to the T5600 which is compatible. Again, I could be wrong on that.

 

Your dv2035us shares the same-numbered system board (#417036-001) as the dv2134us, which sports a T5500 (Merom) from the factory. Since both the board revision & BIOS are identical, I see no reason why the T5600 would not be recognized.

 

Yes the T2050 is only a CoreDuo but the if the chipset/bios itself cant support 4gb then he will never achieve 64bit 4gb. Its a safer route to try the RAM first than the processor

 

Cool, thanks.

I'm supposed to get the notebook later today. It has a busted screen (lid switch issue?), fixing that will be my first priority, but if that goes well (unlike the last two notebooks with busted screens that I've fixed, third time's the charm?) then upgrading its stock CPU and 1GB RAM is tempting. I should probably be lazy and put WinXP on it and call it a day. 1GB RAM just seems low to me, and if I'm going to upgrade why not go straight to 4GB, which needs 64-bit Vista, which needs a Merom...

 

Doesn't these things have the i945 series chipset which from what I can remember of previous posts by users didn't really support 4GB RAM even if you used a 64bit OS??

 

You are likely correct about the 4GB ram issue, as summed up by Greg here http://forum.notebookreview.com/showpost.php?p=2752641&postcount=14

Intel claims 4GB support with this chipset, but obviously we are looking at some type of hardware restriction. http://download.intel.com/design/mobile/datashts/30921905.pdf

 

my dv2000 with a T2500 should have exact same mobo as you, assuming it has a x3100 gpu. I can test out if it supports 4gb later on

EDIT: It says revision -002 (April 2006) of the motherboard will physically support up to 4gb (Mobile Intel® 945GM/GME Express Chipset ). Time to check CPU-z

As for processor assuming you have the Mobile Intel®945GM/GME Express Chipset. Aslong as its the same socket then it should support C2D

 

The X3100-equipped models are from the 965 chipset. The 945 IGP is the GMA 950.......

 

Some idiot told me a while ago that the x3100 and GM945 IGP is the same thing. grrr.. stupid IGP's

Mine says Intel Express graphics.

 

In that case I'll stick with the stock CPU, WinXP, and not attempt 4GB RAM. This is almost certainly a first-rev motherboard.

That's the least of my problems at the moment. This notebook did have the dv2000 lid switch problem that FunnyX documented so nicely. Unfortunately that merely illuminated this:

No external display either, the notebook just locks on startup with that pattern and a blinking underline cursor in the top left corner. I'm guessing that the motherboard is fried? What about the panel itself?

 

Hmm. I'm no expert, but if it is only the screen/inverter/cable that is messed up, the VGA-Out and bootup should be unaffected (?).

 

Check the recall page if it falls in there. If it does then the chances of a dead motherboard are higher

Personally id pull the whole thing apart, inspect it and put it back together. A screen like that could range from a dead gpu to a cpu heatsink screwed in too tightly

 

It's not on the recall list. It's an Intel integrated GPU. Guess I'll have to fully disassemble it, sigh. The inverter works but I need to check the LCD cable, etc. And since it won't POST or even beep I don't have much hope for the motherboard.

Edit: yeah, the panel's busted. It looks like someone smashed their thumb into the left middle of the screen while trying to take it apart. Cosmetically the notebook is in excellent condition but with both the screen and motherboard broken I think it's best to eBay it as broken to one of the many parts merchants, assuming I can't get my money back from the guy who sold it to me. Crap.

 

Success! Well, sort of. The screen is definitely broken but the top third is visible. I'm able to boot and run MemTest86+. I can't toggle the external display, guess that requires booting Windows? Reassembling the notebook with the correct screws must have made a difference. flipfire called it right. I'm still missing a heck of a lot of screws but there's all from the bottom of the notebook now, not from inside. Whew! I'll play with doing a WinXP SP3 install after lunch, there's a broken Ubuntu install on there now.

 

How did you make out with the XP install? Hopefully the board is okay and you can revert to the external monitor until you replace the screen........

 

I got XP SP3 installed, Fn-F4 started working once I got the proper Intel video drivers installed. I used the latest drivers for chipset, video, Ethernet, and wireless from intel.com, Synaptics from synaptics.com, and everything else from hp.com. The left touchpad button doesn't work that well, not sure what that's about yet. Anyhow, no trouble with drivers, no yellow question marks in Device Manager.

Screens are expensive. I'm leaning towards selling this on eBay as broken rather than spending big $$$ fixing up a low-end configuration. Sigh.
