In this post I explain how to upgrade memory or hard drive on Lenovo G570 laptop.
To be precise, I’m working on a Lenovo G570 (Model Name: 4334).
Also, at the end of the post I show how to remove and replace the cooling fan.
Make sure the laptop is turned off before you start disassembly.
Remove laptop battery.
Loosen four screws securing the cover on the bottom.
Lift up and remove the cover.
Remove two screws securing the hard drive.
Slide the hard drive to the left to disconnect it from the motherboard.
Lift up and remove the hard drive.
You’ll have to transfer the mounting bracket and aluminum hard drive shield to the new hard drive.
NOTE: I don’t think you’ll need to transfer the shield if upgrading to a solid-state drive (SSD).
Remove two screws on each side of the hard drive and remove the mounting bracket.
Carefully pill off the aluminum shield.
Lenovo G570 laptop has a regular 2.5″ SATA hard drive installed.
You can upgrade this drive to any other large capacity 2.5″ SATA hard drive or 2.5″ SSD (solid-state drive) which is more expensive but fast and quiet.
I prefer to use known brand SSDs, such as Crucial, Kingston, OCZ.
After replacing the hard drive you’ll have to reinstall the operating system.
Both memory modules can be accessed on the bottom of the laptop.
In order to remove the memory module you’ll have to spread latches on both sides of the memory slot.
The memory module will pop up at a 30 degree angle.
Carefully pull the memory module from the slot buy the edges.
Use same technique to remove the second memory module.
Lenovo G570 (Model Name: 4334) can take up to 8GB RAM.
You can install up to 4GB RAM module into each slot.
Memory used: PC3-10600 DDR3 SDRAM SODIMM 204 pin.
NOTE: your laptop has to run a 64-bit OS to be able to use all 8GB RAM.
REMOVING COOLING FAN.
If the cooling fan started making noise, it can be easily remove and replaced.
In order to remove the fan you’ll have to disconnect one cable from the motherboard and remove three screws.
After that lift up and remove the fan.
If the heat sink is clogged with dust, you can clean it with compressed air.
