In this guide I explain how to take apart an Acer Aspire 5520 laptop.
Also, I believe this model is very similar to Acer Aspire 5220.
Before you start, make sure the computer 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 HDD, you’ll have to transfer the mounting bracket to the new one.
Acer Aspire 5520 uses a regular 2.5″ SATA HDD.
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 the fan.
When the cooling fan removed, you can clean the heatsink using compressed air.
A clogged heatsink can cause laptop overheating and unexpected 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 new thermal grease.
Remove one screw securing the DVD drive.
Pull DVD drive and remove it from the case.
In the following steps I explain how to disconnect and remove the keyboard.
If you would like to replace it, 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 top cover 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.
After the switch board cover removed, you can start removing the keyboard.
There are no screws securing the keyboard.
Insert your fingers between the top side of the keyboard and top cover and carefully lift it up.
Turn the keyboard upside down and place it on the palmrest.
Now you can access the cable connector.
Before you pull the 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 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 cable released, you can remove the keyboard.
Just in case, I’ll show where you can find the CMOS battery.
In Acer Asprie 5520 the CMOS battery soldered to the motherboard.
In the next post I’ll explain how to remove the LCD screen.
