At the end of 2012, I was still a poor man who had just graduated for half a year (and now). In order to facilitate mobile, I changed to this second-hand Acer 4743G, I5 M480, 2G memory (it was replaced with 4G when I bought it), GT 520M graphics card, and 320G hard drive. It has been more than 3 years in the blink of an eye and I will use it, but it has not been very powerful recently. It was okay to use it, but when the temperature was high, the entire CPU was not stuck, so I had the idea of upgrading and cleaning up the dust.
originally wanted to replace the motherboard of 4745 (different models but one mold, the motherboard is universal). Because the graphics card is better, then I7 CPU was replaced. However, after verification, the heat was too high and the heat dissipation could not be suppressed. The heat dissipation was not good, so I gave up this idea. So, in the end, I had to choose to replace the solid-state hard drive and add a piece of memory.
solid-state drives choose Langco's rapid series "Yueying" 256G SATA3 solid-state drives. There are two reasons: one is that the SATA2 interface in the computer room is too strong to perform, and the other is that there is no money. The memory is Taobao's second-hand 4G, and you won't be connected to the link if you spend 100 yuan.
is the protagonist this time
Just say this, start dismantling the machine to clean the dust and sacrifice my dust cleaning tool.
Remove the battery and then disassemble it. Remember.
removes the hard disk and memory in turn, and then removes all the screws behind it.
At this time, the D side cannot be disassembled because there is a screw under the keyboard. When disassembling the keyboard, be careful not to break the keyboard when buckle it. Many netizens said it is easy to break it. Also be careful with the cable under the keyboard.
is the screw and the cable above, all of which are removed.
remove a lot of screws
remove it like this. You can directly remove
on the C side now you need to remove the motherboard, remove the several screws on the motherboard, and then unplug the LCD cable on the motherboard and the power cable below, and carefully break it. This is how the motherboard removed from
is, it's too dirty or not.
and remove the radiator, and then disassemble the radiator
Next is the process of cleaning the dust. I won't demonstrate it, just mess with the brush vacuum cleaner, and then it looks much cleaner. It looks much cleaner. The CPU is also removed and cleaned
and evenly apply a little silicone, and then install the radiator. Note that the CPU lock is not tight enough in the picture below. I didn't install it. Note that the clamping
is now the assembly time. Put the motherboard back in place and install
and then install the C side, lock the screws, and then the D side, install the memory. Two 4G lines are arranged in a row. It’s so cool.
and then install the solid state hard drive. Finally, I can experience the solid state speed. However, it’s only 256G, which is slightly smaller. I don’t install the mechanical hard drive in the optical drive. The main reason is that I have a mobile hard drive box. When needed, just install the old hard drive box to use it.
Then install the lid behind and you're done!
Of course, the new hard disk has a system installation process. After installing win10, it will be resurrected with full health.
Take a screenshot of the entertainment master. The temperature is really touching
Basically, this time the upgrade and cleaning of dust is over. Perfect
only have a few points to pay attention to. Be careful, be careful, be careful, be careful, be careful, be careful, be careful, remember to put the screws well, remember the position wrong, be careful not to break the cable plug and unplug, and don’t forget to install it back, and don’t like me, the CPU is not tight, and it cannot be turned on.
