how to change video card on E6400?

i read the manual, but didn't find any way to change the video card. let me know if this is possible, i'd like to change to more powerful video card. right now, mine is setup with nvidia quadro 160m.

 

It's impossible without replacing the entire motherboard, which will definitely not be cost effective.

 

You need to change the motherboard on the E6400 to change the GPU. The NVS 160M is the most powerful video card you can get with the E6400. You may be able to fit an M2400 motherboard with the FX 370M in your E6400, but even that GPU isn't that much more powerful. If you want a substantially more power graphics solution, you should probably look at an M4400 with the FX 1700M.

 

This is correct. Furthermore, with some exceptions, in all laptops it is impossible to replace the GPU without changing the motherboard (the exceptions use this "MXM" system, google it if you want more information).

 

Technically, with excellent soldiering skills, and a place to get more GPUs, it could technically be feasible, assuming the laptop could supply enough power and cooling. However, the complications of such an attempt could be extreme (including the chance of destroying the computer), so, for all intents and purposes, not doable.

 

True. I should have said "virtually impossible" or something like that.

 

It's fun to imagine the possibilities, right?
I find it a bit frustrating that I have to settle for some pathetic GPU when Asus can have a 14.1" with 9600M GT. I have a small list of things that, if improved, would make the E6400 an ideal laptop.
-Better speakers
-Magnetic latch
-Multitouch synaptics trackpad
-More powerful GPU (9600M, ideally)
-Perhaps, quad core CPU support

 

1) Agreed, the speakers could be better. Although IMO they are not bad for a business laptop.
2) Very true, the small latch looks very fragile.
3) Could be, but not a major issue to me. I like this touchpad.
4) As long as it would be an option. I would still get the lower-end Nvidia card because I don't game that often.
5) Irrelevant to me.

I would be much more interested in a better cooling solution (i.e. not using the thermal foam). It's a great idea to use the chassis of the laptop as a heatsink, but if only they had made proper contact between the GPU and the heatsink the fan wouldn't even need to come on! Don't get me wrong, this is a pretty silent laptop... but it could be even more so.

 

I'm that sense, a M4400 or Apple Macbook Pro are the ideal machines, if only they could be shrunk to a 14.1" form factor.

I personally think the E6400 cooling is excellent. At some point, it becomes more worthwhile just to throw in an SSD - my 7200 spinner makes more noise than my fan (except when gaming). I'm working on a copper mod though in preparation for my coming X9100, so maybe I'll write a nice comprehensive guide this weekend or next week.

 

I thought E6400 with dedicated video (not-integrated), is GPU replaceable? No? Similar like this acer upgrade (dedicated GPU)
