Laptop overheating

Hello,

 

My laptop recently started to over heat again so i brought it to a repair shop.

it is an old problem from last year and they say it's not worth fixing.

 

There diagnostic solution was they replaced a chip that was making it over heat and shut down or

not even start up.

They never exactly told me what chip was doing this and it's too far to go back to ask

 

Would anybody have any suggestions,what it might have been.

 

Thanks

There are a few possibilities as to what the "chip" was;

Northbridge.

Southbridge

GPU

Examples here

CPU (not included as a chip)

 

I would imagine that you were given a large bill for the cost of the repair if any one of the three items above were replaced, this type of repair often exceeds the cost of the MB.

 

What sort of symptoms is the notebook showing at the moment.

Hello Phillpower and thanks for the reply and welcome.

 

Last year it started to shutdown and then it would not start it was heating up so i got it fixed and the solution was to replace a chip (Never told what chip)

i was also told that it might not last.

And now nearly 10 months later same problem again i rang them and they could'nt remember what chip but they siad it would'nt be worth it.

 

Looking at your examples,how is it possible to change any of these chips South Bridge,North Bridge,GPU they look from example unreplaceable.

Must have special tools for the job.

Hello mdealer

 

What is the brand and model name or number of the notebook, I ask as a while back there was a problem with integrated Nvidea video chips, the soldering around the video chip was sub standard and was melting from the heat off the chip, the method used to repair this was known as reflowing, see information here

 

Replacing any chip that is embedded into the MB is a specialist job and that is why the repair is such an expensive one.

Hello Phill,

 

The laptop is a HP G6000.

I was told that replacing the motherboard would solve this problem.

So i am thinking i might do this and save the laptop from the scrap pile.

 

Would you think this would be a good step,i would hate to lose this computer as i have it a while.

 

Thanks Md

Hello MD

 

Thank you for the additional information, your notebook does indeed have an Nvidea video chip which is the Geforce 7000M, these chips were unfortunately dispatched from the manafacturer in vast amounts when they were defective.

 

Here is a thread from 2009 regarding the GPU failure, can I ask how long or how old is the notebook.

 

I also found a separate thread from 2009 regarding a battery recall for your model of notebook (among others) the thread is here

 

 

Replacing the MB is a drastic and expensive step, couple of questions if I may;

Who advised you that replacing the MB would resolve the issue.

Does this person have a 100% working MB that has a video chip that is not one of the many defective ones still out there, if the answer is yes to both how much does the MB cost and most important how good/long is the warranty.

 

I make it my business to avoid commenting on other peoples advice or repair suggestions etc unless their advice is dangerous or completely off, your recollection of the previous repair is somewhat vague so it is not blindingly obvious what the actual repair carried out was,  I have included below some of the information that you previously provided and below that a couple of questions that may refresh your memory which in turn will help us determine what the previous repair was;

 

Last year it started to shutdown and then it would not start it was heating up so i got it fixed and the solution was to replace a chip (Never told what chip)

i was also told that it might not last.

And now nearly 10 months later same problem again i rang them and they could'nt remember what chip but they siad it would'nt be worth it.

 

How much did the repair cost.
Is it possible that the solution was to "reflow" a chip.
 
I have asked the second question here because what you were apparently told ties in with a reflow as it is only deemed as a temporary fix + it is common for a reflow to last no longer than 1 - 3 months.

Thanks Phill for your informative reply.

 

I finally got the repair shop by email and they have told me it was a reflow procedure.Cost to me 70 euros.

 

Lets me say a friend of a friend who used to do repairing work suggested that change the MB will solve the issue.

Cost of MB is 90 euro cost to replace is free as it would be a favour returned.

 

To be honest this laptop has sentimental value to me and members of my family so if it can be done for 90 euros

i am willing to go ahead.

 

The Nvidea chip fault is a worry so i will insist on a warranty.

But going back to the matter at hand,i know you have not seen the pc but in your opinion (No blame or accountability issued)

Would it fix the problem.

 

Thanks MD

Hello MD

This would depend on whether or not the replacement MB also has the same defective chip installation, if it does then I would have to say that it would only be a matter of time before you were in the same position again, do you have a link to the replacement MB, btw I notice that there are plenty of defective ones for sale on ebay.

 

Consider another option, ask the person that owes you a favour to oversee you re-flowing the present gpu yourself, I find HP notebooks one of the easiest to work with and their disassembly guides very easy to follow, keep the different types of screw in separate containers and drop a note in each container identifying where the screws belong.

You are welcome btw  :)
