Asus G750 Disassembly

I think many people are concerned about how this model looks like inside in order to replace the RAM slots, re-install thermal paste, install copper heatsink, etc.
So here are some pics showing how the G750 really looks like.
In my opinion, I don't like the way Asus doing with the G750 series. Unlike most of the laptops in the market, you can easy access the fans for cleaning or re-pasting the thermal compound by open the bottom case.
But with this G750 series, you will need to open everything (like the screen, keyboard, etc.), seriously, in order to re-install the thermal paste. This makes so hard for most people.
This is the G750JW-RB71 model.

​

 

Actually the previous models, like my G73Jh were also like this. The thing is, once you open it up this much, your warranty is probably void. So most people wont do this anyway. In any case, I'd also like to have an easier method of getting to the parts. I just hope they use better thermal compound this time, as they used on the G73 series.

 

Oh my god. that 770M can literally FIT on the previous G75VX motherboard then. It seems if with enough luck, that motherboard can be placed on a G73? maybe a g75!. obviously im just saying with no facts here.


but I can see that the MXM /card is identical to the 670MX. thus replacing this into a g75 is possible.

we just have to wait now for the card to be sold apart

Also, is it me or the CPU fan seems a lil smaller compared to the g75vw/g75vx?

 

Oh nevermind, second thought. I just checked out the stats of a 770M. the 670MX is equal to it. just with lower clock that honestly can be overclocked lol

So people with a 660m or 670m can jump for a 770m

Although if they release an 770MX any time soon. I am sure it will outperform a 680m. I can be wrong but we will see

 

Getting a hold of the part may be tricky, the 780M from the JH I suppose would be the real prize.

 

indeed, but the heat output will be a challenge to tune it down. since the g750JH comes with bigger fans (dual on each so quad)

hm. Unless the extra fans are just gimmick.

 

With the 780M ocing itself depending on temps I doubt it.

 

I don't get something. How this notebook manage to stay cool. I mean I see the big two exhausts at the back, but can't figure out from the pictures how does air intake happens.
I mean if I look at previous Asus G75, it is pretty clear the air intake is on the bottom under each vent. So how does this work for G750?

 

Great pics. Not to jack the thread or anything but here are my own pics when I did the repaste job too. (Before they get lost in the thread forever) I used IC liquid pro. Temps drops about 4-5 degrees. This is the G750JX model 770M

 

Wow so the keyboard and entire surrounding area are one solid piece of aluminum? That's pretty cool.

 

Wow.. This is just too much work. Suppose you put it back together and the temps are terrible. You get to tear that entire system down again just to repaste? Nope! Not for me. Even the GT60 can annoy me, and its a simple process of removing the battery, the bottom panel (6 screws), removing the fan, and removing both the GPU and CPU heatsinks, then repasting. The most difficult and tedeious portion of this is the removal of the proper removal of the thermal paste. I can't even begin to imagine the time it must take to break down this entire G750, and reassemble. I just feel like there is a larger potential for error or possibility of breaking one of those very fragile ribbon cables. I know how easy they are to tear because I messed one up on my old GX660, and it was a serious pain in the A to locate a replacement.

But thank you for those photos Hendrickson. They should be very useful to anyone who decides to take on this task. I know that I would if I owned an Asus, if even only for the curiousity and learning aspect.

 

Yep, that's why I stated that it's the best palmrest in my sig. It gives very good sensations.

 

It's been almost a year since I tore down my G73H and repasted, plus I eventually sold it, but judging from the photos in this thread the overall construction and internal layout look very similar. Which means it's a huge pain to take apart. It took me a few days to get everything squared away on my G73JH, and I was fortunate not to break anything. I never understood why ASUS couldn't fit a more user-friendly internal layout, nevermind standard MXM parts, when they've got so much room to work with in their mammoth 17-inch machines. Even my Lenovo Y500 is easier to take apart, and it's much smaller.

 

They really don't want to encourage users to do it is part of the reason, also their unique shape will involve a slightly more complex internal structure layout.

 

How easy/hard is it to replace the optical drive??? Im going to buy a 750JX next week but its just with a DVD burner and i would like it to have a bluray burner. On the G75VX a friend sayd its just to remove 1 screw from the underneath and pull it out. Do u have to remove the keyboard and buy that ruin the warranty to it now?

 

Optical drive is just as easy as your friend said. Unscrew the bottom plate (the one that allows you to change HDD/SSDs and exposes 2 of the 4 RAM slots). This doesn't void warranty, as you are supposed to be able to upgrade this yourself. Then unscrew one small screw (you can easily figure out which one based on location) and the drive will slide out when pulled.

 

Just remember to switch over the little bracket screwed onto the optical drive, this is custom to each model of notebook.

 

Sir,i wished you waited little more so that you could have bought asus g750jh .My next purchase would be 750jh model.But this model looks good.

 

This reminds me again of how much work it is to open up an Asus G series. My G73 is still going strong though its battery is dead. Had thought of upgrading the RAM on it but what needs to be done in order to access all slots is just too much work for me and I'm afraid I might wreck the fragile ribbon cables for the keyboard and touchpad. I see they still haven't fixed the accessibility problems. Cleaning the fan shouldn't take this much work. Although my M18x has RAM slots under the keyboard, I'm still glad the fans are easily accessible from the bottom. Makes it quicker and easier to clean. As for my GT70, haven't opened it up yet since I feel no need to. I have seen some videos though and it seems way easier to open than an Asus G series. It's a shame really. I always liked the design of the Asus G series. The stealth fighter look really grew on to me. Although I would prefer practicality over looks. Plus I love the battery life of the GT70. Maybe Asus could have achieved the same feat if they used optimus.

 

Tnx guys

 

You can do a lot of the cleaning work by using a small plastic implement to stop the fan rotating and using compressed air through the vents.

 

Guys! This is great as I just received my G750JX today and was frustrated there appeared to be no easy way to get to the other DIMM. While pictures are nice I did not find any post explaining how to specifically get the keyboard off to replace that one enclosed DIMM. Can someone explain the process please?

 

Going by memory, unscrew everything at the bottom, then remove the sticking-out part behind the screen. This will reveal the screen hinges. Unscrew those and carefully slide out the screen (it will still be connected via wires, so watch out). Once the screen is off the hinges, you will be able to lift the keyboard panel, starting at the hinge side (it is screwed there as well).

 

How about replacing the processor? Is it possible? I see a bunch of orange goop on the processor and video card in the photos, are they glued on/welded on?

 

G750 CPUs are not replaceable (soldered into the mobo), and the GPUs use a custom mxm interface, so likely also not replaceable.

edit: actually not really sure about the GPU, it may also be built in the mobo. Can't remember, as when I opened mine I only did it to repaste the CPU.

 

It's a custom card.

 

Thanks bro but I realized shortly after asking there's no real reason for me to delve that far into the guts of this system because it already has enough RAM if I want to assist NASA with launch trajectories.

 

Indeed, for gaming 8GB is more than enough for the next few years imo. If you run many virtual machines, or render/edit large video files, then 16 - 32 gb make sense. Otherwise it's largely wasted.

 

Yes, for the majority of users it's not worth the hassle as 8GB will be good for any gamer.

 

noticed there are a screen different screen connector port for 2D(60hz) and 3D(120hz), but both seems to be 40 pin? Anyone found any pics on a naked g750 with 3D screen where you can see the screen connector?

 

Hi everybody!
I've a technical question about the keybord. Since here in Italy Asus doesn't want to bring the top version (G750JH) with the 780M, but only the G750JX, I'm thinking to buy it from France or Germany, but of course the keyboard will have a different layout. In your opinion it's possible to buy a keyboard (with italian layout) for a 750JX and replace the stock keyboard on the 750JH? I'm not sure if the case of the two models is exactly the same.
Thanks

 

I think the cases are the same. I also think you can purchase a keyboard laid out for your language. You will void your warranty installing it however unless you have a Asus Repair Station do the installation. I would check with your local Asus Repair station they may even have access to the correct keyboard.

 

You can tell windows to assume your natural keyboard layout if you know it well and don't need to look.

 

Most likely you can change the keyboard without voiding your warranty unless some kind of physical damages are inflicted onto the system during the process.
Keyboard contains firmware that registers each key itself in order to be used by its designated region, but it can also become overridden by the BIOS/EC firmware.

 

Hello Com,

How long is the video cable behind the panel, i look for a panel replacement the original ChiMei Panel has a low quality......

Now i found this one:

LP173WF3(SL)(B2) link: LP173WF3(SL)(B2) Replacement Laptop LCD Screen From $104.99 Brand-new screens.




THX for help...

 

I replaced my LCD as well (popped in the old one I had from my Clevo) - you shouldn't need a new cable, just use the one in the laptop (not to mention it's hard to get to the other end of the cable and unplug it). The connector for the LCD you linked seems to be in the standard position, so the cable will be the correct length.

I expect you have a non-3D model to begin with. If you do have a 3D model, then I think the connectors/cables may be different so you would have to be more careful in choosing.

 

Yes if you have a non 3d panel then the standard panels should fit and the cable just move over.

 

While 8GB is enough for games, upgrading to 12/16 or more will activate the dual-channel mode which in turns will give a nice speed increase.

 

That depends entirely on the number and type of RAM sticks you have, and not on the amount of RAM. Having 2 4GB sticks means 8GB total in dual channel. 1 8GB + 1 4GB stick, e.g., will result in single channel 12GB. Timings also matter, as far as I know.

My g750jx came with 2x4GB sticks, and operates in dual channel, for example.

 

Yeah, I assumed 8GB always means 1x 8GB (how mine came). Sure, 2x 4GB is dual channel.

 

It will help but the impact wont actually be that large.

 

12gb will still run dual channel, async mode, or flex mode, depending on the number of sticks and ammount of memory on each ram stick.

 

12GB guarantees 8GB in dual channel and 4GB in single channel no matter the configuration unless you start using 2GB sticks which is unlikely lol.

 

Can anyone explain if you can in fact actually put a GTX 770m MXM card in here?

 

It is not a regular MXM socket so no, you can not upgrade to a different GPU then what its originally designed for.

 

Yep, physically different and the vbios will be in the system bios too most likely so while it could maybe done with a heroic mod, it's not likely to happen and is not going to be worth the time investment.

 

Hi guys

Just joined the forum after coming across this thread. Just bought the 750JX beast however, the configuration I ordered does not include an SSD or 802.11ac. Since you guys have spent a lot of time going into the guts, can anyone please point out where the wifi card is located? I have read in numerous places that the broadcom 802.11ac card that is supposed to be an optional upgrade with this is not available to buy anywhere yet. The best alternate is the INTEL 7260 dual band ac card. This also has wireless display (Widi) and BT 4.0. Can anyone tell me if its even doable? Can it "only" take the broadcom card or can this Intel card be used as well? Where is this located? Is it easy to get to?

The device manager reports Qualcom Atheros AR9485WB-EG Wireless Network Adapter.

I can pick one of the itel ac cards for £20 from Amazon http://www.amazon.co.uk/gp/product/B00D69CJ2Y/ref=ox_sc_sfl_title_6?ie=UTF8&psc=1

Also, it comes with 8GB, what RAM options do I have to push it to 16GB? I use photoshop quite a bit and have multiple photos open all the time with loads of batch processing.

Furthermore, which SSD should I go for?

 

Look at the pics, the wifi card is located immediately to the right of the cpu fan (the smaller of the 2). The white and black wires connected to it are the antennas. I've replaced my atheros for a different one, so there is no whitelisting going on, any card that fits should work.

You can use CPU-Z to see how your ram is configured (1x8 or 2x4). The laptop has 4 ram slots total, 2 easily accessible from the bottom, 2 not so much (though if you're replacing the wifi card, you'll be opening it up anyways). Make sure you get the haswell-ready low voltage ram.

The Samsung 840 series is considered quite good, though I doubt you can go wrong with an SSD from any of the major manufacturers.

 

Great advice thank you. Which wifi card are you using? Why did you change it? Is it an AC card? The only AC card I can find is the Intel one.

Samsung 840 is the way to go then

 

I replaced it for another N card (a dell wireless 1510, BCM94322HM8L BCM4322 if you need numbers), not an AC. I wanted to have functioning wifi under OS X without a dongle, and the Atheros I had (and you have) doesn't work under OS X.
