Re: How to know if the problem is from a bad cap ?
Hi back.
Would you give me some advice to choose/buy flux and other stuff I would need.
It seems there are different quality flux and solder wick. What would you advice from Ebay for instance. (by the time, Ebay is my main electronic supplier because is cheap from China !)

Re: How to know if the problem is from a bad cap ?
First I'd like to know how you know it ? Where did you get this information from ? Sorry to be so curious.
"Reflow" , you mean giving the chip a heat shoot without replacing?
Undervolting ? How ? I haven't seen such option in my BIOS !
can I use my regulated hot air gun for top, and a well regulated (PID Arduino stuff) grill underneath for preheating ?
Would you have some good tutorial link for DIYers.

Re: How to know if the problem is from a bad cap ?
Ok, I see, that's the reason I couldn't find a way in the BIOS to switch from integrated chipset to an eGPU.
I saw the story about the lawsuit, but we are now in 2014, almost 2015.
By the way, very interesting. They kept on saling they're bad chipset for so long !
I think it would be hard to ask about an extended warranty to get a fix or refund !
A shame because that's my brother's laptop and it failed moreless in 2009 actually. But he and I didn't know at that time !

Re: How to know if the problem is from a bad cap ?
Hi I'm coming back enquiring an idea.
Would it be possible to neutralise the NVIDIA chipset and add an external Graphic Card on my laptop to be sure the problem is from the NVIDIA G6100 chipset.
I have IEEE1394 port (firewire) and ExpressCard slot free on the laptop. Would one of these would be useful.
Sorry for insisting working on this old laptop, but I hate not to be sure and not understanding about what I'm doing.
I think it would need to neutralise integrated NVIDIA...Leave a comment:

Re: How to know if the problem is from a bad cap ?
Thanks very much for your advices !
I found these, but some specify the date 2010+ or 2009+, and with or whitout balls.

Re: How to know if the problem is from a bad cap ?
Very disappointing indeed ! My laptop is from 2006, so 8 years old.
Would it be worth it attempting a new chip and a reballing ?
Edit :
I think that's what I need so !:

Do you think it's possible to find a new chip already with the balls ?
So I have only to drop i and heat it in place. I don't have the stencil and equipment...Last edited by hary66; 09-23-2014, 06:37 AM.Leave a comment:

Re: How to know if the problem is from a bad cap ?
If you're talking about the DDR2 SoDimm Ram, I've already substitutd them. As I've 2 SoDimm, I've left only one at a time, them moved it to the other slot, then did the same with the 2nd RAM, but nothing better neither worst : No change !
For those interested, I've posted some more pictures to show what happens, (the video artifacts) from different try.
Also some picture of my board and the GPU and other chip.
I have a thermal camera and I noticed the chip on picture 11...Leave a comment:

Re: How to know if the problem is from a bad cap ?
Thanks you for your help.
I've been reconsidering the fact and if I hit the computer (keypad) a bit, it would happen everytime.
I went underneath and hit the different chip with no success to make it fail !
Of course the GPU (NVIDIA G6100) is underneath the cooling system so not really reachable.
I try to bend the MOBO with no more success to localise the failing area !
The defect mostly response when I knock the computer, but not the MOBO

How to know if the problem is from a bad cap ?
Hello.
I have an MSI M670 MS-1632 laptop with strange behaviour.
(the screen sometimes goes ok, sometimes, it doesn't light on at all, sometimes it lights on then goes off, and sometimes it transform the writing in many rectangles moving the writing in different pieces all over the screen. It need 1-3 times to start. Then it goes ok for hours. Sometimes, not.
This happens during the POST or during the OS is loading or after the OS has loaded.
It made me thinking of a bad cap symptom. Because in some way, it behave like a versatile PSU with old... -

Hi, I'm Harold from France.
I'm here because I'm facing problem recognizing laptop MOBO capacitors.
I'm happy that I found this place, I hope I'll be able to learn more about Caps .Leave a comment:
