Hello everyone and Welcome to HowFixit. In this video I gonna show you how to
disassemble the Asus Zenbook UX490 laptop, clean it from dust and replace thermal paste.
To disassemble Asus UX490 you will need next tools:
Phillips 1 screwdriver Torx T5 screwdriver
Plastic tool Tweezers
Antistatic brush Thermal grease
Also I recommend using a magnetic mat in repair process and laying out each screw step-by-step
during disassembly, which is especially useful in the case of the Asus UX490. This
laptop has a lot of screws of different sizes and it is very important not to confuse them
during assembly. In the description, I’ll leave links where to buy all the necessary tools.
Turn the laptop over and remove all the screws on the bottom cover.
Next, take a plastic tool and begin to open the case of laptop.
I recommend using a plastic tool so as not to damage the laptop case when you opening.
Disconnect the battery cable from the motherboard.
Now let's begin to the removal of the cooling system.
Disconnect fan cables. Remove all screws on the cooling system.
Now let's begin cleaning the cooling system from dust. Remove all dust from the radiator and fan.
To clean the motherboard from dust, use only an antistatic brush.
Pay attention to the order of removing the screws; I recommend unscrewing in the indicated order.
Now you can remove cooling system by lifting up from the motherboard.
Remove the old thermal paste from the surface of the CPU, as well as from the radiator. If
thermal grease is very dry and doesn't rub well, you can use isopropyl alcohol.
How to apply thermal grease. Apply a small amount of thermal paste to the processor,
then take a plastic tool and spread it evenly over the entire surface of the chip.
If you still don’t know which thermal grease to choose, in the description, I left a link
to the video where I test different thermal greases and choose the best one for the laptop.
If your laptop is still overheating after cleaning and replacing the thermal grease,
I recommend watching a video about the cooling pad for the laptop, or how to undervolting CPU and GPU
to reduce heat and increase laptop performance. All links you can found in the description.
Well, that's all, you were on HowFixit and see you guys next time!
