In this guide I explain how to take apart an Acer Aspire 5520 laptop.
Also, I believe this laptop is very similar to Acer Aspire 5220.
I’ll go though the following procedures:
1. Removing hard drive and memory.
2. Removing cooling fan and heatsink.
3. Removing keyboard.
It’s possible the guide will work for some other Acer Aspire models. If it works for you, please mention the model number in comments bellow.
In the next post I’ll explain how to remove and replace the LCD screen
Before you start, make sure the laptop is turned off and battery removed.
Remove two screws securing the hard drive cover. Lift up and remove the cover.
Remove four screws securing the memory/cooling fan/wireless card cover. Lift up and remove the cover.
In my case the memory cover was seated very tightly.
I had to use a guitar pick in order to separate the cover from the laptop base.
After all covers are removed you’ll get an access to the hard drive, both memory modules, wireless card and cooling module.
Slide the hard drive assembly to the left and disconnect it from the motherboard.
Lift up and remove the hard drive assembly.
If you are replacing or upgrading the hard drive, you’ll have to transfer the mounting bracket to the new drive.
Acer Aspire 5520 uses a regular 2.5″ SATA hard drive. Any large SATA hard drive should work fine in this laptop.
In order to remove the memory module, you’ll have to spread latches on both sides of the memory slot.
After the memory module pops up at a 30 degree angle, you can pull it from the slot.
Acer Aspire 5520 can take up to 4GB RAM total. There are two memory slot, so you can install up to 2GB RAM module into each slot.
Memory used: DDR2 667MHz (PC2-5300) SODIMM.
Remove three screws securing the cooling fan.
Disconnect the cooling fan cable from the motherboard.
Lift up and remove cooling fan.
When the cooling fan removed, you can clean the heatsink using compressed air.
A clogged heatsink can cause laptop overheating and unexpected laptop shut downs.
If you would like to apply fresh thermal grease on the processor, you’ll have to remove the heatsink assembly first.
Loosen four screws securing the heatsink assembly, carefully separate it from the processor and remove from the laptop.
After that you can apply fresh thermal grease on the processor.
Remove one screw securing the DVD drive.
Pull DVD drive from the laptop.
REMOVING AND REPLACING LAPTOP KEYBOARD.
In the following steps I explain how to disconnect and remove laptop keyboard. If you would like to replace the keyboard, it’s not necessary to go though all previous steps (except removing the main battery).
Remove three screws from the battery compartment.
These screws securing the switch board cover.
Separate the switch board cover from the laptop base using a guitar pick (or any other piece of soft plastic).
Lift up the switch board cover.
Continue removing the switch board cover with your fingers.
Remove the switch board cover from the laptop.
After the switch board cover removed, you can start removing the keyboard.
There are no screws securing the keyboard like in many other laptops.
Insert your fingers between the top side of the keyboard and laptop base and carefully lift up the keyboard.
Turn the keyboard upside down and place it on the palmrest.
Now you can access the keyboard cable connector.
Before you pull the keyboard cable from the connector, you’ll have to unlock the connector.
To unlock the connector, move the brown clip about 2 millimeters towards the touchpad.
Do not apply too much force. The brown clip must stay attached to the connector base.
On the following picture the keyboard connector shown in the unlocked state.
You see, the brown clip still attached to the connector base.
Now you can pull the ribbon cable from the connector.
After the keyboard cable release, you can remove the keyboard.
Just in case, I’ll show where you can find the CMOS battery.
In Acer Asprie 5520 laptop the CMOS battery soldered to the motherboard.
