lol, sorry bro, having class for the whole day@@ didn't notice ur post. Well now i'm quite busy coz i need to present case for my doctor. So for now i cannot make a guide with pictures.

But i can roughly guide u here thru words. Ok, first thing first, u turn to the bottom of the laptop. Unscrew every screw u see, take out ur harddisc(the whole thing with the metal thing), unplug ur ram also. Coz there is a hidden screw under the ram, this screw secured ur touchpad one. The wifi card u might wan to plug off the black and white wires. Then remember there are 3 more screw under the battery(if u are plugging battery now). Then u can take a flat screw driver to pry ur dvd-rom out which will make ur disassemble much easier(just one screw securing the dvd-room at the back).

after u unscrew everything single screw ady, flip it back and open up ur lid. Now u will take out the speaker grill first. U might need something sharp coz the grill fit nicely. U need to pry off from both left and right top corner. U might need to use a bit of force coz there are hinge under it. after the speaker grill come off, there are a few more screw securing the keyboard and the speaker. As usual, unscrew all of them.(make sure u put ur screw accordingly so u know how to put it back later). After the keyboard come off, u will see a ribbon attached to ur keyboard and touchpad. Unplug them both also. Then there are a few screws securing the metal with the motherboard. Unscrew them also. Ok, now u need something sharp also, u need to start prying the edge of the whole front plate(the place it hold keyboard, the touchpad and all). There are hinge all around it so u might need to go slow and take ur time.

After u take out the whole thing, ur motherboard is pretty much exposed. But the usb port vga port are still attached to the left side of ur laptop. So u might wan to push it a bit from the outside then ur motherboard goes free xD.

Now the only wires that attached to the motherboard should be the screen only. For my case coz it seems too fragile so i didn't unplug it. I just let the screen attached to my motherboard. Now the heatsink for gpu and cpu are beneath the motherboard. Turn it over, then u should see them.

WARNING(!!!!!) this is very important, u should see a yellow sticker for warranty one stick somewhere around here(mine one was sticked on one of the cpu screw). I took it out slowly and stick it somewhere else. Don break this sticker, its warranty sticker.

WARNING(!!!!!)before u unscrew and take out ur heatsink, becareful, next to ur cpu there is a thing black in colour that has a shape for a flat screwdriver one. That thing basically locks ur CPU in place. So basically u need to use a flat screw driver to turn it to the other side to unlock ur cpu. If u try to take the cpu out with this thing locked u might breaks ur cpu.

So u are pretty much there xD. Just take out the heatsink, clean it properly, make sure u wipe the remaining thermal paste clean. Then apply ur new artic cooling mx-4 xD. Don apply too much, if too much it might cause negative effect. Then after that slowly assemble back ur laptop xD.
