Do you have any more pictures of your process? I've been trying to repaste but 1) The CPU seems totally fused to the heatsink (can't budge it), and 2) I can't figure out how to expose the GPU. I don't see how you would remove the heatsink because it's sandwiched between the vents.

Also, I had a bit of a freakout last night...after trying to remove the CPU I gave up and replaced the back cover. Pressed the power button and the 3 ASUS "touch lights" came on, but that was it. No post, no BIOS. I went to bed thinking I had fried the CPU with an errant static shock. In the morning I opened it back up...realized I hadn't turned back the release "screw" on the CPU seating, lol. Booted right up after that. I'll definitely be doing some backups tonight though!

I do have some more pictures. Jmalpica on page 215 also has some nice photos you may find useful. Let me begin by saying I am NOT a computer repairman so if something goes horribly wrong don't blame me. These are just the techniques I used and found to be effective. I'll also add that repasting your cores will VOID YOUR WARRANTY if you still have it!

If you haven't done so already, check the fan compartment before repasting! It's much much easier to do and dust coating the copper cooling fins can drastically reduce the cooling capabilities of the single exhaust fan of the G51JX. To do so, shut down your computer, unplug everything, remove the battery, ground yourself, then remove the access panel.

Spoiler :

In the above photo, the circled regions are the screws you need to remove to access the inner portion of the fan. You also may need to remove the power cable for the fan in order to fully remove it. Do this by gently pulling upward on the off-white plastic connector (it helps if you have fingernails). Do not pull on the wires themselves! You don't want to accidentally kill the only thing keeping your computer as cool as it is. The next picture shows a little of this as well. You can then just pop the top off the fan and dust it out.

If you're sure you need to do a repaste, let your computer run for a little bit before powering down and disassembling as before. You need to work quickly but carefully while the thermal paste is still viscous from the heat. Both the GPU and CPU heatsink attachments have four screws each. In addition to this there is an aluminum section above the GPU heatsink. Unfortunately they use a partially joined assembly and this can make it difficult to remove. While you can leave the fan cord attached if you must, it's easier to work with if it's disconnected as well.

Spoiler :

Spoiler :

These pictures show the screws you need to remove before the assembly can come free. The aluminum part may be separated from the copper one. They're held together by the rubber adhesive. If possible, gently remove this from one of the two components. If you can't just be careful when handling it as it tears quite easily.

Here's another shot of the heatsink assembly removed from the computer.

Spoiler :

Properly done the heatsink assembly should be extremely easy to remove. You shouldn't have to apply much force at all to separate the chips from the metal. If you have to tug and exert effort to get it to come loose you need to step back and make sure all the screws are indeed free (keep track of which goes to where by the way). The chips can be "reheated" with the use of something like a hairdryer to soften the paste up again by carefully heating the copper elements. Don't do this unless you absolutely have to. You could potentially build up a static charge somewhere and I'm sure there's a whole slew of better reasons to not do this, but it will work in a pinch if you're desperate.

Save the thermal tape patches! I left my old ones there assuming there was a reason the designers opted for tape over paste near the GPU chips. You might have to browse for more information about these.

Once you manage to remove the assembly, you may need to use a small amount of isopropyl alcohol to help remove the built up gunk. I recommend a small microfiber cloth. Just be patient and avoid harsh motions. The last thing you want to do is gouge or scratch the CPU/GPU chips.

Edit 2: I forgot to mention, DO NOT FORGET TO REATTACH THE FAN POWER CABLE! This is the only thing cooling your CPU and GPU. Horrible things will happen if you forget to attach this and start running intensive programs.

For the actual repasting itself, there are a number of guides specific to the paste you chose to use available on youtube. I won't cover that unless someone explicitly asks. I would advise against Arctic 5 Silver. I did not see significant temperature drops whereas Jmalpica's Noctua NT-H1 thermal paste reportedly did very well.

Edit: Those pictures turned out absolutely massive, sorry about that. If this is infringing on forum policy please let me know and I'll see if I can downsize them.

Hey guys I have a x2 model thats 2 years old my battery died about 6 months ago so I've just been using the power cord. However, recently when i try to play games my laptop will just shut down in the middle of a game. I thought it was just overheating at first and so i got a fan and turned down the settings to low when i normally run them on high. This worked for a little bit until now and now about 20 minutes into any game it will shut down on me. It runs perfectly fine if i dont play games. I'm not great with computers does anyone have any ideas about what the problem is. Do i just need to buy a new battery? Thanks for any help or advice you can give.

jcihm your shut downs are almost certainly heat related. Check your internal temperatures using a program like GPU-Z or RealTemp. If your video card passes ~105 C your computer will shut down to try and prevent damage. The G51JX runs hot but you shouldn't be seeing temperatures above 90 on your video card for the most part. I'd highly recommend dusting out the exhaust fan fins. Even a small layer of dust can drastically decrease your cooling fan's performance. Do this first (it's fast and easy, just don't loose the screws!) then check your temps again. I'd imagine you might have a large wad of accumulated dust over the fins.

Replacing your battery won't solve the shut down issues, but if you travel frequently with your computer you may want to look into purchasing a replacement.

hey steelgryphon thanks for your reply. i cleaned the fans out which had a little bit of dust and i noticed it reduced my gpus temperature when idle but its still at about 78 C and when i played a game (SCII) the temperatures are consisently at about 100 and it will shut down after about 20 minutes of game play. the cpu fan hits about 6000 RPM

I had the same issue with overheating, thanks to you guides I got my CPU temp down by 10c ( to 60ish) and my GPU temp down by 25 ( to 55ish).

I couldn't get my hands on any of the good stuff so i had to use Arctic Aluminia Premium Ceramic. It's doing the job so far so no complaints. If i can get my hands on something better I'll re seat them.

Yep, that's overheating alright. Need to change your Thermal Paste/Compound, but this will void your warranty.
Others have sent their laptop with the Thermal Paste of their choosing, back to Asus Service Center. And requested for a re-paste using their paste, so not to void their warranty.
Maybe this may help you.

Hi all, I haven't been here in quite a long time. Hope everybody's doing well.

Sad news for me. I think my GPU is dying. Need some help here.

Background:
My computer's Specs. is on my signature. Just click "show" button.
Everything are original (haven't upgraded anything, except re-paste with Antec Formula 5). All are "stock" too (never overclock).

Symptoms:
Booting will last for a few seconds only, then it freezes. Even in CMOS Settings if I get lucky getting in.
Then, after reboot... the screen will just stay blank/black (as in, nothing shows up).
These... even when there's just 1 stick of RAM, and no Hard Drive. The HDD LED indicator will blink indicating activity on HDD, but the screen stays blank.

Questions:
1. Is my assessment right? Is it the video card, and not the mobo or the processor?
2. Has anyone upgraded their G51Jx-X5, G51Jx-A1 or G60Jx computer's video card successfully? If so, what card did you use? Where and how much?
3. Can somebody assist me on which card to pick?
I was thinking, since I'm replacing the GPU... why not upgrade if the price is close to the GTS 360m with 1gb ddr5 vram.
4. Suggestions...??

My limited information:
The G51Jx-X5's mobo I have is a G60Jx board.
The GPU pcb board is a G60Jx VGA MXM Board Rev. 2.0
There's a green sticker...
PN: 60-NYLVG1000-C11
PT: N0A81010VG0007555
69N0GZV10C11-01
and says N11E GS1-A3 on the GPU Chip itself.
Asus uses MXM format on their mobile video card.

which means, it's a MXM 2.0 video card.

I'd very much appreciate the help, thanks.

Hi All ,

I had Overheating problem when I am watching a video in my ASUS G51JX-A1 - the nvidia card was geeting to 108° & shutting down , So I made a PPT Guide & upload it to Youtube - the guide is about how to replace the Thermal Grease from the CPU & the Nvidia video card & clean the fan .
For me it's realy help ,now its working very good & not shutting down anymore.
