HP 8560W CPU replacement

Hello all,
I am a long time viewer of this forum, but my first post as I cannot find the information I need.
I am planning to replace the CPU of my HP 8560W (from i5 to i7). The heatsink should be sufficient (otherwise I will let it run slower).
My problem is that I don't know how to open the thing. I am assuming the CPU can be reached through opening the keyboard (so it's under the keyboard). I am getting stuck however, as I have all screws removed, but keyboard seems to be solidly attached, not even a little bit loose. I am sure it's the right screws (all 3 of them).
After looking through HP documentation I realise that I am stuck at point 8 ( HP EliteBook 8560w Mobile Workstation- HP EliteBook 8560w Mobile Workstation - Removing and Replacing the Keyboard - c02907289 - HP Business Support Center)

How do I remove the keyboard?

Thanks,
Sokar

EDIT: I have watched this video and the guy seems to be something at the back of the laptop on step 2 - am I missing something? ( How to remove keyboard on a HP 8560P - YouTube). Maybe this is only for 8560p, not 8560w - but just in case..

 

Back when I had that laptop, I encountered the same problem... the 8560w keyboard removal mechanism wasn't designed properly and requires excessive force, at least on the early revisions; basically just push the keyboard like your life depends on it :, see this thread: http://forum.notebookreview.com/hp-business-class-notebooks/608629-8560w-stiff-keyboard.html

 

Thanks for your reply, I got it out

 

Will a quad core CPU work on a board that originally had an i5 (dual-core) CPU? I remember there were 2 different system boards.
One had 4 RAM slots and was designed for use with quad core CPU's and the other had 2 RAM slots for use with dual core CPU's.

Or is it just the case that if you upgrade to a quad core you will only be able to use 2 RAM slots but it will still work?

 

@repman244
Have a look at the Maintenance manual as there's a list of CPU's that'll work with the machine. There are two versions of the 8760w so the 8560w manual will clear this for you.

 

I am looking at it, but if you look at the system board replacement you will see that there are 2 types. One for dual core and one for quad core CPU's.
Will the dual core board take a quad core CPU?

 

I tried to put a quad CPU in (which appeared to be a 2820XM, not QM as I ordered). The guy was apparently a fraud.
In any case, the laptop would occasionally turn on and get to windows, and occasionally it wouldn't. My mobo is with 2 RAM slots, that might be 1 reason, unsupported CPU might be another. I have read somewhere also that I cannot upgrade the CPU of 8560w, without changing the system board (why would that be?), even if I get a proper 2820QM processor. Anybody knows anything on this?

If anyone has replaced their CPU successfully, please let me know.


I was meaning to post also a short how-to-remove-keyboard for others:
It becomes much easier if, next to removing the 3 screws, you also remove the DVD-player (just 1 screw). Once you completely remove the DVD-player, you can push the keyboard out from the back.
The keyboard is very well attached, so this does need some 'delicate' strength.
But this way you don't need to use your screwdriver or something else on the visible body with the fear of scratching your new laptop.

 

2820XM ?? There is no such CPU AFAIK. Try running CPU-Z and see exactly which CPU it is. 2820QM is supported.
Do you have the latest BIOS installed?

 

Do not know if things become any different with 8560W, but I had the same problem with 8530W (T9600) and a Qx9300 CPU - HP Dual core "prescribed" motherboard just won't provide it with the right voltage, there are some info on the web for undervolting and even a pin mod for this quad core support.

 

Yeah that is most likely the case here. The VRM is most likely different for the dual cores and isn't designed to handle power demands of the quad core CPU's.

 

2820XM is en ES that didn't get released to public (I actually contacted Intel for this). It worked fine on my i5 dualcore Probook 6560b (but I had to make sure it would never run full speed, so max temps would be 70 C). The CPU works, I am sure of that.
I assume that there is a problem with what the poster before me is saying (dual-core won't run on the system due to low power that the system board provides). I have to say that when I did try it, I didn't have the latest BIOS (I had F.22, I think). Now I have run out of cooling paste, so I cannot try it with latest BIOS (F.27). I will do so when it arrives some time next week, and keep you posted.

I would like to hear from someone who owes a 8560W whether they have successfully went from i5 to i7 without a problem, cause if it is impossible, I don't want to open and close my laptop without a reason.

(PS heating I don't mind, as I am not going to run it full speed - basically the same trick I used with my ProBook 6560b to keep it 70C max).

 

I see, just a word of advice if you end up selling it: be careful not to get caught by someone (Intel), ES CPU's are Intel's property.

 

I am not planning on selling this baby, I just got it recently and am very happy with it. Besides I always keep the original CPU for that cituation.
I bought the ES from someone claiming it was an QM as well, and I don't want to dupe someone as they duped me.

BUT, I have contacted Intel about the issue and they were not interested in getting the CPU back (seeing that it didn't work on my new machine, there is no need to keep it).
After I asked whether it was ok for me to sell it on ebay, I didn't get an answer, which makes me think that it would be ok to sell it, but they don't condone the practice of selling ES CPU's.

In any case, I want to give it another try once I get thermal paste, but it would be helpful to know whether someone else has been able to upgrade from i5-2540m to a quadcore CPU (officially supported or not), before I start opening my laptop again.
