Okay.. so since almost a month, my laptop keeps shutting down while watching 720p videos... and its not as much as a shut down as it is going off without any warning...

So i googled and gt results that it might be over heating...
downloaded gpu-z and saw that while watching 720p videos, the temperature went up to 107 degrees and at that time the laptop closes...

So i opened up the laptop and cleaned the fan...
No avail...
Again opened up and removed the heat sink, cleaned it, applied a new coat of thermal paste and re fixed the heat sink..
Again, no avail...

Den i gt fed up and gave it to a repair shop....
Guy asked me to replace the heat sink and said the problem would be solved..
I did it...
now the problem has reduced, but in no ways has it totally gone away...
So i took it back to him and showed that it still shuts down...
He said it is a graphics chip problem and the chip needs to be replaced....

Now i'm not sure i want to spend soo much money on getting a new graphics chip and then realize it was useless....
Also, the laptop functions completely normal while watching normal videos, 480p videos, and surfing the net....

So since this is a hardware experts forum, can any1 tell me if this seems like graphics chip failure or some other problem?

Also, will using cooling pads help?

My System Specs:

Computer Type: Laptop
System Manufacturer/Model Number: Lenovo Ideapad Z560
OS:Windows 8
CPU: Intel Core I3 CPU M380 @ 2.53 GHZ(4 CPUs)
Memory: 3027 MB RAM
Graphics Card: Nvidia GeForce 310M with CUDA
Sound Card: Conexant SmartAudio HD

P.S.
About a month and a half ago, i had my speakers changed caz they were fried since 2-3 months...
Not sure if this is related, but ever since i have had new speakers, this problem has begun...

Yes I think that is best to just hold off on it. Your system is a few years old and you want to upgrade anyways so just save your money and buy a good laptop in 6-8 months when you get the chance.

If you do not have any more questions please mark one of getochkn's posts or one of my posts as he solution so this thread will be closed.
Enjoy your new laptop when you get it :)

Yea with the laptop as new as it is, I would have advised you turn it in for a replacement before doing anything you did. After you cleaned it out it seemed almost certain that the graphics chip was bad. You can't replace it either, you need an entire new laptop, but by opening it if you had warranty you have surely voided it now.

A cooling pad may help, but honestly I don't think it will make it completely fine. You still probably will have the problem. I don't think its fixable.

Just to correct the above post, you can replace a graphics chip if you have a BGA reflow workstation. I've done it before on laptops. Also removed and reballed BGA laptop chips before as well, so don't say it can't be done. It can if your willing to pay and know an experienced person.

Oh my laptop is almost 3.5 yrs old.. so no issues with opening it up.. if it was in warranty i wouldnt have even tried to find out what the problem was...
And the guy i gave it in repair to, i askd him the same thing caz i know quite enough about computers that i know that graphics chip cant be changed...
But he is like u cant upgrade it or install new chip, but u can surely put a new chip of the same old make and size...
so like i have nvidia geforce 310m 512mb, he said i cant upgrade it to 1 gb or instead of 310m i cant make it 410m or whatever, but i can surely replace the 310m 512mb with another 310m 512 mb...
I found that a little fishy so i refused him and took back my laptop

I understood getochkn. What he is saying makes sense, and I can see that it is possible to do so. The shop you went to makes sense with what he was saying also, but it is a risky procedure. Make a mistake while removing the old chip and putting the new one on and you could easily break the system. It just isn't something I personally would consider doing every unless it was getting tossed in the trash if this didn't work.

So if it is a big critical issue to you, that you pretty much won't use the system without being able to watch 720p video, then I would let the guy go ahead and replace the chip, but if you are okay without it and not at that point yet I would hold off.

Good job getting the thing apart and cleaned though. That can be a real pain to do at times.

Basically saying the repair guy is right, you can change chips on a laptop, it just requires someone with the right skills and equipment.

The chip is soldered to the board, but with a BGA reflow machine, you can lift the chip and either replace the solder on the chip, as lead free solder has a lot of problems on all chips (this is the major cause of the PS3 yellow light of death and the 360 red ring of death).

In addition, your graphics may be an MXM type graphics card like this.

In which case it's pop out and replace.



But even if you have a chip soldered on that looks like this, http://www.notebookcheck.net/uploads/tx_nbc2/GeForce_310m_3qtr_med.png it can be replaced, I've done laptops, ps3's, 360's, some chips for TV's, anything with a chip soldered down can be removed and replaced if your good.

Yeah i guess i can use this laptop for another 6-8 months.. i was planning to buy a new laptop next summer as i am impressed with the new intel haswel processors and wanted to try them out...
So i guess from now on i will just have to download hdtv movies and tv serials....
And i dnt really play games on dis anymore...

Oh and idk about other systems, but mine was fairly easy to open and clean... i even took the fan apart to clean its fins, without any problem.. I had the whole thing disassembled and up and running in about 2-2.5 hours...
