In this guide I explain how to disassemble an Acer Aspire 5745 series laptop (I’m taking apart Acer Aspire 5745G-6726).
The guide might work for some other Acer Aspire models. If it works for you, please mention the laptop model number in the comments.
I’ll go though the following major disassembly steps:
STEP1-4: Removing hard drive, memory. Accessing CMOS battery and wireless card.
STEP 5-11: Disconnecting and removing keyboard.
STEP 12-15: Removing top cover assembly.
STEP 16-21: Disconnecting and removing laptop display panel.
STEP 22-25: Removing laptop motherboard.
STEP 26-27: Accessing laptop cooling fan and DC jack harness.
Before you start, make sure the laptop is turned off and battery removed.
STEP 1.
Remove eight screws securing the hard drive and memory cover.
One of the screws (green) securing the DVD drive.
Lift up and remove the cover.
STEP 2.
Under the cover you’ll find the following components:
- Hard drive.
- Memory modules.
- CMOS battery
- Wireless card.
For the purpose of my guide it’s not necessary to remove memory modules, CMOS battery and wireless card. You can leave them connected to the motherboard.
By the way, Acer Aspire 5745 laptop has FOUR memory slots. This laptop can handle up to 16GB RAM total (4GB RAM module in each slot).
Acer Aspire 5745 laptop takes PC3-8500 DDR3-1066 memory. In order to take advantage of all 16GB RAM you’ll have to run a 64-bit OS.
STEP 3.
Remove the hard drive.
Simply slide it to the left to disconnect from the motherboard and lift up.
This is a regular 2.5″ SATA hard drive.
STEP 4.
Pull the DVD drive and remove it from the laptop.
The DVD drive was secured with one screws (green) which we removed in the step 1.
STEP 5.
The keyboard is secured by six spring loaded latches.
STEP 6.
In order to remove the keyboard you’ll have to push in all six latches.
Push on the latch with a small flat head screwdriver. When the latch pushed in, the keyboard will lift up a little bit.
STEP 7.
Lift up the top side of the keyboard and place it upside down on the palm rest.
STEP 8.
Now you can access the keyboard cable connector. You’ll have to unlock the connector and release the cable before you can remove the keyboard.
STEP 9.
On the following picture the keyboard connector shown in the locked position.
In order to unlock the connector, lift up the right side of the brown locking tab. It will open up at a 90 degree angle.
STEP 10.
On the following picture the connector shown in the unlocked position.
Now you can pull the keyboard cable from the connector.
STEP 11.
Remove the keyboard.

STEP 12.
Remove all screws securing laptop case on the bottom.
STEP 13.
Remove nine screws securing the top cover assembly.
Disconnect four cables.
STEP 14.
Start separating the top cover assembly from the bottom case as it shown on the following picture.
STEP 15.
Remove the top cover assembly.
STEP 16.
In the following part of the guide I’ll be removing the display assembly.
The wireless card antenna cables are mounted inside the display panel.
In order to separate the display panel from the laptop base it’s necessary to disconnect the wireless card antenna cables.
STEP 17.
Carefully disconnect both wireless card antenna cables (white and black) from the wireless card.
Unroute both antenna cables on the bottom of the laptop.
STEP 18.
Release both antenna cables.
STEP 19.
Disconnect the video cable connector from the motherboard.
Unplug the web camera cable.
Both cables are glued to the cooling fan assembly. Carefully lift up and unglue both cables.
STEP 20.
Remove two screws securing display hinges.
STEP 21.
Lift up and remove the display panel.
In one of the next guides I’ll explain how to replace the LCD screen.
STEP 22.
Remove one screws securing the motherboard.
Disconnect the USB board cable from the motherboard.
STEP 23.
Before you can remove the motherboard you’ll have to unplug the DC jack cable. This cable located under the cover we removed in the step 1.
STEP 24.
Lift up the left side of the motherboard and start removing it from the bottom case.
STEP 25.
The motherboard removed.
STEP 26.
You can remove the cooling fan assembly following these steps:
- Remove/loosen seven screws securing the heat sink.
- Disconnect fan cable from the motherboard.
- Carefully lift up and remove the cooling fan assembly.
STEP 27.
In Acer Aspire 5745 laptop the DC jack is not soldered directly to the motherboard.
The DC jack attached to the harness.

Hi, and thanks for the first answer.
I have started to disassemble my laptop to replace the two hinges. To remove the top cover, have I to remove before the screws of bottom cover?
Thanks again.

Thanks for this, it helped me get a piece of plastic (left in by manufacturer) out of the fan assembly where it was causing chaos. I can hardly believe the fan was so inaccessible!
Just a heads up, on the AA 5745PG model, there is an extra screw on the bottom of the laptop, between the DVD drive and the hinge. Also, there’s another connection to the motherboard exactly where the DC jack connection is, but on the other side of the motherboard. It too must be disconnected and can be done in step 23 as well.

Sorry for double posting, but i forgot the reason I came here in the first place. Does your model of the 5745G come with bluetooth. If it does, do you know where it is? I have disassembled my 5745G many times now and suddenly my bluetooth doesn’t work anymore. I am sure I have the model with bluetooth since I remeber connecting my phone to it, but since it doesn’t show up and when i try to install drivers it says no device connected. Is there any disconnected cables or such that could cause this problem?

I also got an Acer Aspire 5745G and I had the overheat problem. I tried several time to clean the fan to make it run cooler, but the thing that fixed my problem was to update the bios. This fixed so that my laptop doesn’t suddenly shut down anymore. Just something you with overeheating problems should try.

My acer aspire 5745G heats up very soon when Im playing heavy games and then it’ll suddenly shutdown by itself. The place under the cooling fan gets heated up the most and also the temperature goes upt 90 deg C(I saw using a software).
So I wanted to open up my laptop, do the cleaning n make holes in the outer plastic body under the fan so that the heat can go outside and the laptop doesnt shutdowns suddenly.
Any suggestions how to open up easily and do that??

I have exactly the same Acer model here. Recently, I have been experiencing unexpected shutdown. It just happened recently and I was monitoring the temperature and it was hovering at about 60+ C and doesn’t make sense to be overheated? I have also ran memory test for a few hours and didn’t seem to be any problem. Any other ideas?
