Dell :: Replacing Geforce 8400m GS GPU On A Vostro 1400?

Feb 22, 2010

So I have a broken Nvidia Geforce 8400m GS GPU on my Vostro 1400 out-of-warranty (even with Nvidia extension) laptop and Dell wants $240 to repair it.

That money could probably go to a new laptop, but I was still wondering if there was a way I could go for a do-it-yourself repair. How would I go about replacing the GPU? Is there a guide for this somewhere I could look for?

I'm guessing I will need to order a replacement motherboard from Dell to do this, but I'd rather attempt repairing the laptop on my own rather than send it to Dell's out-of-warranty repair depot. I've taken apart PCs before, but have never taken apart a laptop.

Dell :: Replacing Vostro 1400 Motherboard?

Mar 22, 2009

I'm wondering if you guys can help me find a few resources to purchase/install a new motherboard on my Vostro 1400. One day out of the blue, the thing stopped charging.

I had the charger replaced, as the charger itself was still under warranty, but the system has been out of warranty since last August, which makes getting help from Dell a ver trying experience.

I was given the choice of either extending my warranty for $257 for 1 year, $317 for 2 years (yeah right!), or $358 for a one off repai

Dell :: Vostro 1400 Replacement, What Is Comparable Now Since 1400 Is Not In Production

Sep 23, 2009

Dell is sending me a new unit as replacement to my faulty Dell 1400.

I had the = discrete nvidia graphics option along with the upgraded Dell screen (wxga+).

My question is this? Which will they send? They say it will be comparable. How can it be comparable if they dont even make a 14.1" vostro anymore? I don't want a 15" clunker because the reason i got the 14" was because of portibility.

I also dont wanna get stuck with onboard intel crap graphics, will they give me discrete video card?

Dell :: XPS M1330 NVidia GeForce 8400M GSCopper Mod

Jul 2, 2008

Dell XPS M1330 - nVidia GeForce 8400M GS - Copper Mod - Step by Step Guide

Dell XPS M1330 Notebook with nVidia GeForce 8400M GS GPU has an inadequate Thermal Cooling Assembly. It uses a Thermal Cooling Pad between the GPU and the GPU Thermal Cooling Assembly instead of a direct contact between the two with a Thermal Compound. This leads to overheating the GPU and damaging it along with other components. The solution is to replace the existing Thermal Cooling Pad with a Copper Sheet and a Thermal Compound.

Note: This Copper Mod does not solve problems arising from a weak die/packaging material set in certain versions of GPU. Their failure appears related to the combination of the interaction between the chip material set and the system design. The combination of limited thermal management and frequent power cycling is particularly challenging for the GPU. Dell is offering a 12 Month Limited Warranty Enhancement specific to this issue. However, this Copper Mod might help delay the failure by improving the thermal management.


01. Copper Sheet. Recommended: Gauge 16 & Grade C106 - 14x14x1.5mm.
02. Thermal Compound. Recommended: Arctic Silver 5.
03. Thermal Compound Cleaner (Isopropyl Alcohol or Acetone).
04. Cotton Swabs.
05. Paper Napkins.


01. Phillips Screwdriver - #0.
02. Utility Knife.
03. Thermal Compound Spreader.

Drivers & Utilities: (for Microsoft Windows Vista 32 Bit)

01. Dell XPS M1330 A13 - 1.02MB. (BIOS Firmware). Recommended.
02. Dell nVidia GeForce 8400M GS 176.44 A10 - 52.70MB. (Video Driver). Recommended.
03. HWMonitor 1.11 - 397.00KB. (Monitor GPU, CPU, Chipset and HDD Temperatures).
04. GPU-Z 0.2.8 - 410.00KB. (Monitor GPU Clocks).
05. I8kfanGUI 3.1 - 1.61MB. (Monitor Fan Status and Speed).
06. RivaTuner 2.11 - 2.30MB. (Monitor GPU Status on OSD).
07. 3DMark06 Basic Edition 1.1.0 - 413.00MB. (Benchmark GPU).
08. Intel Thermal Analysis Tool 2.05 - 3.31MB. (Benchmark CPU).


Before You Begin!

01. Disassemble the Module Cover by loosening the four Screws.

I have a Acer Aspire 5720G, with a Geforce 8400M GS graphics card apparently, i have every other driver installed for xp. The only one i cant seem to get to work is the graphics driver. I have tried Google and downloaded numerous drivers but i cant seem to find one that will work, they all either wont install because they don't recognize the hardware, or with custom inf's from laptopvideo2go they install then when i boot windows, then say they're incompatible and have reverted back to the default VGA drivers.

Sony :: Vaio VGN-FZ18M Driver For Geforce 8400M GT Is Not Compatible

Dec 30, 2009

I have a Sony Vaio VGN-FZ18M Laptop (Running Vista Home Premium) which I would like to update to Windows 7 Ultimate.

On running MS compatibility Checker it points out that the Driver for Geforce 8400M GT is not compatible.

When I try to find a new driver via NVIDIA I keep being referred to Sony who seem to have washed their hands of the problem See reply message below.

Can you point me at a driver that will work with Windows 7 or has anyone updated to Windows 7 with this Geforce 8400M GT driver and had any success.

I seem to be going round in circles trying to find a solution.

i.e. NVIDIA say go to Sony and SONY say go to NVIDIA

I note from searching the net that there are many people out there with Vaio FZ models having similar problems and that Sony seem to have created upgrades for quiet a number of their models but have stated “Please note that your computer is not eligible for the Upgrade to Windows 7.”

This I find disgraceful for a Company to completely wash its hands of supporting a machine that is barely 2 years old and the fact the New OS from MS is seen as an industry standard which they will be delivering in future. They refer to it as 3rd Party Software which their reply would infer they are not going to support in their machines. I wonder if that applies to their latest models?

Nov 1, 2009

I have got Vostro 1400 with GeForce 8400M GS and graphic card failed... I tried to reflow the chip and it worked for 5 day and then it go wrong again...

My last chance is change motherboard... I look at ebay and I found motherboard with integrated Intel graphic... Is it possible to change motherboard with integrated VGA instead of one with GeForce VGA?

I think it should work, but I'm not sure and I don't want to be surprised after spending 200 USD on new motherboard.

Dell :: Vostro 1400 Possible Fan Going Bad

Jul 20, 2009

I have Vostro 1400 and it has been a rock for last 2 years I have had it. Recently it developed a rattling type of noise coming from the fan.

It is almost continous but sometimes stops for a second or two. Fan seems to be working OK for now.

Also I noticed if I put me ear next to the fan while the laptop is flat I can clearly hear the noise but I turn the laptop vertical to the ground the fan rattling almost goes away

Dell :: Vostro 1400 -- New Heatsink

Feb 18, 2010

I should have said microprocessing cooling unit, not heatsink!

My Dell Vostro 1400 laptop has been running hotter with age (it's two years old). About 5 minutes after startup the core temp hits 50-60C, the fan kicks in, the core goes down to 30C, the fan kicks off. This cycle occurs about every 5 minutes or so. I've cleaned the fan area thoroughly and am using i8kfanGUI. I'm wondering if replacing the microprocessing cooling unit will help keep the core temp down. They're pretty cheap, about £15 on eBay. Here's what I'm looking at:

What do you guys think? Will a new microprocessing cooling unit make a significant difference in keeping down my core temp?

Dell :: Serious Problem With My Vostro 1400

Sep 26, 2009

Ive been having a pretty bad problem with my vostro and its getting worse, I hope someone can help.

So once in a while my computer completely freezes- keyboard and mouse too. I used to be able to restart it and it worked fine after.

But lately it started going into startup repair after I try to restart it. The colours get messed up too. It does system restore to be able to start back up.

The last time it happened, it was really bad, it took about 6 or 7 restarts to start normally - it would either keep doing the repair or freeze again when I entered my password.

Dell :: [Vostro 1400] CPU Load To 100% After 5 Min?

Jul 26, 2009

This is on a vostro 1400 with the notorious 8400M. Recently, whenever I run a game (any game, even older ones like WC3) or anything graphics-intensive such as movies, the cpu load increases until it hits 100% and the system basically freezes until I exit whatever program was running.

For the first 5-10 of a game, everything runs smoothly, but eventually the cpu load maxes and I have to quit. the sound is also messed up, which i think is just an effect of the cpu load.

Dell :: Vostro 1400 Dead LCD Screen

Oct 18, 2009

I had firefox running with several tabs, then I went afk for a while and when I came back, the screen was blank. I shook the mouse, made sure it wasn't sleeping, tried alt-ctrl-del, but I got nothing. Then I did a manual restart by holding the power button then starting it up again.

I could hear the sound of the login screen coming up, I entered my password and it was able to login to Windows since I heard that Windows startup sound. I still couldn't see anything on the screen. I plugged in my external LCD to see if that could detect anything but it said "no signal detected".

Does anybody have a solution for this? Or is my laptop pretty much dead?

My specs are:
T7100 1.8ghz
2gb ram
8400 gs
vista home 32bit

Dell :: Vostro 1400 Screen Dead

Apr 3, 2010

The screen on my Dell Vostro 1400 just died on me. I can turn on the laptop and I hear Vista booting but the screen doesn't show up. The Dell Logo doesn't even show up when I turn on the laptop.

So to diagnose this problem, I connected my LCD monitor to the laptop. The screen appeared but tere is flickers of color everywhere and the screen resolution is terrible. I think the graphics card burned out. I was wondering if my diagnosis is correct?

Also if it is burned out, is it easy to swap graphic cards? I have a GEforce 8600 GS on my laptop. It is not connected with the motherboard.

My Vostro screen is really really dim, I've never noticed this until I compared it to other laptops and screens.

I was wondering how is your Vostro 1400? are you happy with the brightness?

I'm not sure what make of a screen I have but I'd gladly buy a new one and replace this one if I knew other screen makes for this model are brighter.

Here's the comparison shot with 1400 vs Vostro 1300, brightness of both is set to max.

Dell :: Possibility Of 8600m GT In A Vostro 1400

Feb 6, 2008

I see that right now the 8400GS is the best you can get in a Vostro 1400. The Vostro 1500 supports both the 8400GS and the 8600m GT. I'm assuming then that a 8600m GT would fit perfectly into a Vostro 1400. Has anyone tried it? Sorry if this has been asked before, I tired searching for it and found nothing.

Dell Vostro 1400 :: Installing OS Without Product Key

Mar 16, 2013

- My Dell laptop's motherboard is fried and needs replacing (Vostro 1400) - I can't read the Product Key for the copy of Windows installed on it, because the sticker underneath the laptop is worn out - Dell said that as long as I use the recovery disc supplied by them, it won't even ask me for the Product Key on install because it reads the data off the motherboard - If I replace the motherboard, does that mean I can't install Windows on the system without it asking for a Product Key again?

In other words: do all Vostro 1400 motherboards have the same SLIC digital signature? Will I be able to install Vista Business 32-bit without it asking for a Product Key?
