In this guide, I’ll show you how to replace CPU, add memory and SSD in Lenovo Y470. And there are specific explanation of every step. Some precautions will be mentioned too.
If you are not familiar with disassembly and you own a Lenovo Y470, this will help you a lot.
1. When the laptop is installed with ES version CPU, the indicator light will sparkle once and then dark down when boot. It’s different from the official version. So when it occur, do not panic.
2. After CPU is installed, try to do the light up test with a power adapter. Because it occurred to me once the battery didn’t work while the power adapter did.
3. Be aware of the different length and position of screws.
Here are all the components that’ll come into use for the replacement:
Two 4G 1333Mhz DDR3 memory, a Samsung 840pro 128G solid-state drive, a i7-2625QM CPU (ES version), a CD ROM bracket to install HDD (12.7mm version) and silica gel.
Remove the battery and all the screws on the bottom cover first with a cross screwdriver.
The battery must be removed first! If you feel like your hands are electrostatic, try to touch an iron pipe such as a heating pipe, a screwdriver head.
Open the bottom cover, we can access Wi-Fi network card, Southbridge chips, memory, cooling fan, and HDD in the main drive bay.
Remove the HDD. There are 2 screws, a long one and a short one. Take care when you reassemble it.
Then push the HDD to the screw side, HDD can be removed directly.
Remove the optical drive. Note the screw on the center. Unscrew it and pull it down. This screw is a long one.
The removed optical drive. Remember to remove the optical drive cover, there are a few clips.
Make sure you know the position of every screw and then spring the SD card reader cover out.
This is an important part of the laptop. If you’ve used a laptop for a long time, the turnbuckles are easily damaged because of the high temperature.
Then we can break it apart with hands.
Then unplug the power button cable and the touchpad button cable.
Then let’s move on.
When reassemble, make sure the screws on the dissipating module are tightened in the order of 1 -7.
As the CPU is ES version, it’s important to ensure it’ll light up the motherboard.
