Yeah, they usually like that. You'll need to call them instead.

[damandatwin]

Yeah, I called them and now it's all arranged.

Hi,

I disassembled my A42JV today by following this guide. I did re-paste thermal paste & clean the FAN grills a bit. Unfortunately, I don't have proper digital camera. If not, I can write complete disassembly guide. I have several comment though:-

• The (AC) power connector are tightly connected to the plug on the motherboard. I tried a bit & it refused to come off. I decided just removed both main board & daughter board. If I'm able to disconnect the power connector, I don't have to removed the display.
  (The AC power connector is the cable connected the daughter board to main board. The daughter board is where the AC power port, ethernet & USB ports are located.)
  
  The upper left is the daughter board. Between the wireless card & CMOS battery, you can see the power connector I'm talking about.
  
• The heatsink is very disappointing. It doesn't use the spring screws like normally use on a heatsink. It also seems doesn't put any pressure at all on the CPU & GPU which can cause poor thermal conductivity. I replaced the thermal paste & can only see little improvement.
  
  The heatsink feet where the screws go also made of thin aluminum.
  

Do not use any metal object at all when working on the motherboard, e.g. disconnecting cables/connectors, because you don't want to damaged the motherboard. Just use your hand. Happen to me on my old Acer Aspire 9420 - accidentally knocked out two very small capacitors/resistors & have to spent some amount of money to get it repaired at computer repair shop. Also don't force it if the connector won't come off. Just surrender like a gentleman.

TIPS

• To clean the FAN, only need to removed the keyboard. The FAN blade is accessible after removing the keyboard (see picture above). There are 4 clips at the top that holding the keyboard in place. Start from left or right, push the first clip to inside the casing (upward), lift the keyboard a little bit & continue do the same thing with the other clips.
• Wireless card also located under the keyboard.
• The CMOS battery also located under the keyboard but it is inaccessible until you removed the upper cover.
• Keyboard is the second item you need to removed after DVD drive when you're going to disassembled A42JV/K42JV notebook. DVD drive is secured by two screws underneath the notebook. Both screws are labeled with a CD icon.

Hello, somebody knows where i can buy this orange termal pad on the videocard?

[kizwan]

Hi,

If you're referring to the orange tape on the CPU & GPU, it's actually not thermal pad. It just a tape put there by Asus. It's not even required.

[areh007]

Ok, thank you. Can you tell normall temperature in a simple (when noutbook turn on and programm doesn`t work)

[kizwan]

Right after booting into windows, the CPU temperatures are in 50C to 60C. Idle temperatures are 45C to 47C. Room temperature between 32C to 36C. When playing games CPU temperatures can goes up to 85C to 91C, almost 15C higher than my Dell quad-core i7-720QM processor. Copper shims might help.

Anyway, it is very fun playing games on this notebook especially when traveling/outstation.

wow this is awsome!, if i only want to clean the fan which screw i must remove?, can do you put some highlight in your picture?, pleaseeee

[kizwan]

To clean the FAN, you just need to removed the keyboard. No screws involved. There are 4 pins that holding the keyboard in place. The pins are "spring pins". You just need to use plastic ruler. You can start from right or left. Push one pin toward inside the casing, lift the keyboard a little bit & push the next pin. Repeat the steps for the remaining pins. Then you can use compressed air can to clean the dust on the FAN & grills.

Sorry, I don't have proper camera to show you.
