Disassemble the acer aspire 4741G

Down a total of five kinds of screws, so it is necessary to prepare a small phillips screwdriver set, if it is a bit of magnetic so much the better. Old silicon grease dry hard, thermal efficiency is greatly reduced, silicone is essential nature; To clean up the old silicon grease, I recommend using anhydrous alcohol, in the domestic 500 ml bottle of 8-10 yuan, there are three benefits: one of alcohol is not conductive, don’t worry about short circuit, and alcohol is organic solvent, clean and dry silicone like boiling soup and snow, sweeping, thirdly alcohol volatile is very strong, do not have to worry about leaving residual solvent, if not that is best prepared blotting paper, water after dry cleaning carefully, can’t leave water damage; In addition, should besmear good new silicon grease and dust, small cotton swabs is essential; Finally I recommend with a clean tray to pack the screw, it is not easy to lose, if not familiar to the whole process, can also spread out a blank sheet of paper on the surface of the table to remove the screw in the corresponding position in case you forget.

1.Dismantle the four red in the below image type A screw (i.e., the above mentioned the first screw), finger from the cavity into, and then pick up the cover plate, to separate both sides, slid open card buckle one by one.

5.Dismantle battery compartments in the 5 C type screw, and the 3 B type screw on one side of the battery (middle a type B is fixed drives, simply removed the screws can directly pull out the optical drive), you can see in the picture below to the right of the 2 B and 4 C.

Loosen the fan exhaust line first.

Next, just loosen the radiator pipe 6 D type screw column (cannot be removed, can only loose), radiator pipe can be removed, revealing the CPU radiator pipe (triangle cover part) and under the GPU.

Cotton swab dipped in anhydrous alcohol, it can be easily erased on the chip surface and radiator pipe cured silicone, very easy. I thick wiped the CPU, the effect is as follows.

Don’t busy with silicon grease, should clean up the fan and the discharge pipe.
