The overheating and the nVidia chip are not connected - the problem with the chip is neither caused by nor causes overheating (though overheating CAN destroy the chip, as it can any other chip or component in the system).  The problem with the chips stems from thermal cycling, not overheating.

If you're under warranty, you can ask if they will replace the system.  If what you're asking is will they replace a system under the video chip extended warranty, the answer is no.

In addition to what ejn63 said:

Overheating is a result of poor heat transfer from the CPU and GPU to the heat pipe. There is a single heat pipe and fan in the M1530; CPU and GPU are therefore linked, and both will increse in temp if there is a problem with one.

The first thing to do is to make sure the fan is working. Download CPUID HW Monitor and follow the various temperatures and fan speeds. If you do not see the fan speed increase while the temps go up, run the fan test in the Dell Diagnostics (F12 at the Boot).

If the fan is OK, next thing is to blow out the "dust bunnies" using electronic compressed gas.

If this doesn't help, then you will need to go inside the laptop. First thing is to check that the heat sinks are both tightly installed. If they are OK, the the last possibility is poor application of heat transfer paste to the GPU or CPU /heatsink assembly and/or an improperly installed heat transfer pad. the paste needs to be replaced (Arctic Silver) or the pad replaced.

To reiterate, overheating IS NOT caused by the GPU problem.

No one is denying the 8400GS and 8600GT used in the M1530 have the engineering fault that nVida made with ALL these chips.

Your bias is preventing you from understanding the difference between OVERHEATING and the nVidia GPU fault.  The problem is that the chips break down from repeated thermal cycling (heating and cooldown in normal operation).  The fault with the chips has absolutely, positively NOTHING to do with causing or being caused by overheating - it is a flaw in the material and design used to make the chips.

If the system is overheating, it is caused by something other than the faulty GPU - could be a bad fan, dusty heatsink, abusive operator (i.e., using the system in your lap and blocking the cooling vents), bad seal between the heatsink and GPU or CPU, or just a bad mainboard with a bad voltage regulator.

IF you're seeing the video artifacts (black screen, spurious lines, characters) common to the GPU fault, that's covered by the extended warranty.  From what you've written, you're just seeing overheating - which is NOT caused by the GPU, and NOT covered by the extended warranty.

Not at all.  The problem with your system isn't the video chip - it's overheating.  If you're under warranty, Dell is obligated to fix it (or replace the system).  As with anything else you buy, repairs after the warranty expires are at your expense.

Lolz...looks like u r a dell official because u r trying to prove dell right every time..just google and see what the results say about xps m1530 notebook and nvidia you are weird......hate dell.

If you want to direct your money next time, buy a system with Intel or ATI video - not nVidia, and you'll be punishing the right people.

Which brings us to interesting point. Do we have to research every element put into computer we propose to buy? Should'nt we expect that Dell will check these things for us, and would not offer computers with parts which are known to have faults?

I, personally appreciate your input into this forum. I would love to be able to talk to you before my next computer purchase - unfortunately it will not be before some two years.

Keep on good work - I try to read all your comments.

Unfortunately, your hatred and bias have blinded you to the truth.

The problem is with nVidia, NOT with Dell.  These chips fail in Dells - and HP, Lenovo, Apple, Compaq, Sony, Toshiba, Acer/Gateway/eMachine - and every other notebook.  The M1530's smaller counterpart, the M1330, came with Intel and nVidia video - guess which one generates very few problems/complaints?

If you want to direct your money next time, buy a system with Intel or ATI video - not nVidia, and you'll be punishing the right people.

It's almost impossible to do that.  Notebooks are inherently unreliable devices - no one would accept a new car model where 30% of cars sold had a major component like an engine or transmission fail within the first three years, and yet that's par for the course with notebooks.  Even the worst of the worst - and in the US, that'd be Chrysler - is better than that.  The best defense is a 3 year warranty and reasonable expectations - you're not going to get more than that out of a notebook on average, and if you do, it's a bonus.
