HP Pavilion ENVY 15T Manual CPU Upgrade

I currently own an HP Pavilion ENVY 15T with a Core i5-430M processor. I want to upgrade the processor either to a Core i5-540M Dual Core, or Core i7-820QM Quad Core. Is this possible?

I have looked up YouTube videos, and have found instructions on installing a bigger hard drive: YouTube - How to: HP Envy 15 SSD install

I've even found the general HP ENVY 15 service manual on this forum, which doesn't mention anything about Core i5 processors, only the Core i7-720QM, and the Core i7-820QM processors.

Does anyone have any information, or experience on opening HP Envy 15T models with Core i5 processors?

 

It is possible yes. Go for it but be warned that the i7 Quads will kill battery life and increase temperatures.

 

Sweet! Will do, and thanks!

 

there is someone from other forum told me that

"Users over at NotebookReview.com have successfully upgraded an i5 envy 15 to an i7 without any hassle. check over there for good reading."

but i couldn't find it can somebody here help me with this?

 

I'm under the impression that you cannot upgrade from an i5 to an i7, unless you mean an i7-620M which is really just another Arrandale... (Unless you want to switch motherboards?!)

 

You yourself cannot do this because it is very complicated, take it to a good HP authorized technician. Changing from dual to quad is possible if you flash the VBIOS on the ATI, you need the ROM image and flashing util for it, if you cannot get those then you must replace motherboard since the ATI chip is on it. If the flash procedure fails, it will brick the motherboard and you would have to buy a new one. I am not talking about flashing the CMOS/BIOS, that is different. You would also need to replace the HSF assy, because 45w clarksfield use a different one than 35w arrandale machines, they get hotter. Upgrading to the same class of CPU is more easy, your best bet is to upgrade to the i5 580M, i7 620M, or the upcoming i7 640M. The 640 is going to be the last ever arrandale chip, and faster than some of the quads. The system BIOS must support the new chip for it to work, but it probably will. If your machine is still under warranty, you have to buy the replacement CPU part from HP or they will not guarantee that part... That should be all you need to know.

 

so the best thing i can upgrade is i7 640M?

just unplug the i5 and plug the i7 640M??

You can upgrade to i7-720 or 820 if you want in place of the i5, johnnobts from the envy 15 2nd gen thread has done this, only downside is you don't get the usb 3.0 ports that you would have got if you had ordered the i7 in the first place, but for most people it's not an issue.

 

These will be the last and best upgrades.
dual core: i7 640M @ 35w
quad core: i7 840QM @ 45w
quad core "extreme": 940XM @ 55w

You can easily upgrade to the same class of CPU, dual->dual or quad->quad. Upgrading to a different class gives problems as I mentioned earlier. The extreme chip would probably run too hot in an envy, its using 55w, you would have to do a case mod to keep it from overheating. But hey if you are an extreme guy you won't mind modding the HSF or cutting a big hole and adding a blower to your envy to make it work

Upgrading is a tricky procedure, better to pay someone to do it. CPU is underneath of the HSF assy, you cant just pop one out and another in. If you want to try it yourself here are some tips: you should buy an antistatic mat w/ wrist strap that snaps to the mat. Plug the laptop and the lead for the wriststrap+mat into a powerstrip with its switch *OFF* because you do not want the laptop to actually have power reaching it so remove its battery too, then plug your powerstrip to the wall and put the strap on your wrist. That will keep yourself and the laptop and the mat grounded and at equal potential as you work on it. Any parts you place on the mat will be safe now, and you are less likely to damage the CPU while handling it, never touch the pins though even when grounded, always hold parts by the edge. Dont work in a carpeted area either! You must clean old thermal material from the HSF before reapplying the new stuff, you can do that with pure acetone from the hardware store, don't use nail polish remover. There is more to learn, these are just some tips.

 

so this ENVY 2nd GEN can use a i7 840QM / 820QM, that is a good news and can i have a link to johnnobts thread?

 

Do the 2nd gen envy15 have a switchable graphics feature? That makes it complicated.

 

In all honesty, thinking a hdd upgrade is of the same caliber as a cpu upgrade is a warning sign. In most laptops you'll have to take apart almost all of it to get to the point to swap the cpu. Personally I'd recommend experience on desktop cpu changing before you even attempted doing it on a notebook, but the stock hsf would be alright with a 15w processor increase as long as you use a decent thermal paste.

And a last word of advice, its not worth voiding your warranty(if you're still covered by it).

 

if i have experienced changing couple of notebook processor like ASUS core2duo notebook and Toshiba Centrino notebook, changin my ASUS notebook monitor from HD ready to FULL HD , do you think i can do this processor upgrade or i need other preparation?

warranty is not a problem for me

 

I just sighed at the sight of the thread, so much bad answers....

Hey op do yourself a favor and pm johnbots he will teach you how to do it.

@e14

the BIOS supports it already, since there is only one BIOS update for the total of envy 15 machines.

There is no relation in flashing the BIOS and that interfering with swapping the cpus or that the cpu will interfere in any way with the 5830.

When you swap the processor in your desktop do you flash your BIOS because your gpu won't adapt/recognize or whatever that you're thinking?

The same process applies here.

 

Yea you should be fine then
