Replacing a CPU voids warranty?

[smids]

Hello,

I found these forums a few days ago - very interesting reading - I've been through the first 30 pages or so (to about Jan 15th, around the time of Yonah's release).

Now, I understand IBM's policy about FRU's and CRU's and I have searched this topic but have not found a reasonable answer. I have the Laptop in sig - T41 2373 8RG Warranty expires 31-10-2007. I want to upgrade it however. I am looking to upgrade the mini-pci wireless (CRU), RAM (CRU), HDU - now is this a CRU or FRU, it really should be a CRU - I want to put a 7200rpm drive in (very interesting threads on these at the moment) and the CPU. Now the CPU is an oddity; it is labelled as a non-serviceable FRU. So basically if the CPU fails, then you are out of luck as is it not under warranty. So basically you cannot replace it without voiding the warranty?

About replacing the CPU (I'm very experienced with computers, I build them for friends and family, overclock them, and my main desktop is custom watercooled) with either a 755 (2.0ghz Dothan, 2MB L2, 400FSB). Given the predicament we face with regards to warranty, is this viable? Have others done this. I've had practice with IBM's as I stripped down my sister's T22 when it broke out of warranty. I'm very careful and have never broken anything in any of my builds. I will use AS5 as the new thermal compound. The reason for all of this is to replace the current hot, power hungry (relatively) Banias 1.6ghz. I've read the service manual for this - it looks straightforwards as I'll need to do most of the preliminary steps to change the wireless mini-pci. IBM say you need to remove the screen for this - I don't believe you do. I looked under the keyboard and the only reason I can see mention of this is that the aerial cables *might* be mildly in the way but this may be remedied by detaching it from the m-pci card.

Do others have any comments/views? I apologise for the length of the above!

Welcome to the Thinkpad Forums

I am pretty sure that replacing a CPU does void the warranty; but there is an interesting thread here on applying thermal compound such as AS5, see

http://forum.thinkpads.com/viewtopic.php?t=24230

The HDD should be a very simple replacement, but I am not sure about the mini-PCI...Have you had a look at both the movies online and the HMM for your model?

No problem with the length; best to run everything you are thinking of through first, little matter the length of the post, rather than speak a little then have many questions while you are actually doing it and quite possibly mess something up that could have been avoided altogether in the first place.

I've read through that thermal grease thread - I always do my homework .

[censored], is the only thing I could say. I mean I know that changing the CPU is not going to dramaitcally alter the system in any way; not so much in any event to cause major system problems - I could understand if it was modding something in someway though. What could I do if something failed with the new CPU in, completely unrelated to that e.g. blown capacitor or gpu as so often happens in laptops (how my sister's T22 died, as well as my father's Vaio).
I think it's possibly wrong of IBM to not allow the user the replace the CPU when they don't warranty it themselves.

Yes, I have seen the videos, as well as read the HMM. It's a pretty straightforward job for me as I do things of this sort all the time. The mini-pci isn't the most straightforward thing despite being a tier 1 (apprently) CRU, as you require the removal of the front palm rest and touchad (it is located directly beneath the touchpad).

I can either live with it, or void my warranty - lovely choice. Could I ask IBM to replace it do you think? Or would they just laugh in my face and tell me they are too busy....


EDIT - whilst I am here - just a quick other question: it's looking likely that I will replace the HDU - this isn't a warranty voiding thing is it? Now, I want to create a set of rescue media, but [censored] lenovo, in their infinite wisdom, didn't think too carefully of those without CDRW drives. I tried using my Sony HD5 HD music player as a USB HDU but it wasn't recognised by the Rescue and Recovery software, despite Windows seeing it as removable USB Mass storage - has anyone got a workaround for this?

I have upgraded the cpu of my t40 two times from banias 1.5 to dothan 1.8 to dothan 2.10 and just two months ago the gpu on my also upgraded mobo failed and ibm replaced the mobo in warranty no questions asked.

if you are careful and do the job right reinstall everything the way it was before
you won't have any problems with the warranty.
I don't think they will check wich cpu you have or the grease you use.

[smids]

Oh believe me, I'm extremely careful - when dealing with watercooling which leaked initially, you learn to be extremely careful with things. Thankfully, as I always take precautions and the deionised water did its bit. That was my first build anyway, so I've come a long way since then.

A quick question - do you need to apply thermal paste to the GPU as well as CPU (I hear the fan also cools the GPU - Radeon 7500).

[cmarti]

The grease on the gpu is not required. The gpu on you model is not in contat with the fan. Even if you have a 128 mb video mobo it is not required.

Where did you ever get the idea that IBM/Lenovo don't warrant the CPU against failure?

If the original CPU goes teats up within the warranty period, they'll replace the motherboard completely.

And that is the reason you should keep the old one after the upgrade. For warranty reasons.

The parts list lists the CPU as a non-serviceable part.

Yes, and as James said, they replace the motherboard when the CPU needs repair.

I didn't dispute that, I was merely noting my source of information as he asked a question.

It's quite good that they replace the motherboard - often, if it's not heat, this will be the killer as CPU's don't often tend to just fail as it were.

Hello all,

I have couple questions.

I have a T40 2373-72v with banias 1.5.

Thinking of moving to dothan 2.1.

1. I wonder what is the performance difference?

2. Some website selling 478 pin cpu, and some selling 479 pin. which one should i get?

or better yet, if someone who already did the upgrade, could you just link me the same web site and the same product you purchased?

Thanks.

[cmarti]

The performance increase depends on what programs/applications you run on your T40.

For me was EXCELENT!!!

But remember also to use artic silver 5

And yes all sl7v3 aka. 765 aka. 2.10 400fsb pentium m cpu's will work on your lappy.

Just remember to upgrade your controler and also the BIOS.

[shigeru_go]

what is artic silver 5? and what is sl7v3?

is sl7v3 = 765?

the specific application i was using is video playback >< i am having lots lag..

and it's a clean install too ><

does all dothan cpu work on t40 as long as it got 400 fsb?

Because i am having difficulty finding a vendor carryiing a 765 cpu

Thanks

[cmarti]

slv7v3 is the name for the pentium 765.

I think you should use the search feature of this forum do your homework and many of your questions will dissapear.
