In this guide I’ll explain how to take apart an Acer Aspire 5100 laptop. I’ll show how to remove and replace major laptop components such as CD/DVD drive, memory, hard drive, wireless card, cooling fan and keyboard.
In the next article I’ll explain how to remove LCD screen and replace inverter board.
First of all, make sure the laptop is turned off, the power adapter is disconnected and the battery is removed.
Both memory modules, wireless card, cooling and and hard drive can be accessed from the bottom. Remove four screws marked with red circles and loosen two screws marked with green circles. Remove both covers.
You can search for Acer Aspire 5100 spare parts here.
Find brand new replacement laptop batteries in stock and ready to ship your way.
Removing DVD drive:
1. Remove one screw (red circle) securing the drive.
2. Push the drive from the laptop with a flathead screwdriver.
3. Pull the drive form the laptop.
Removing hard drive:
1. Pull the hard drive to the right side until it’s disconnected from the motherboard.
2. Lift up the hard drive.
If you are replacing the hard drive with a new one, you’ll have to transfer the mounting bracket to a new drive.
My laptop had a 80GB 5400RPM SATA hard drive installed. You can upgrade it to a larger and faster SATA drive.
100GB, 120GB, 160GB and 250GB SATA drives should work just fine in this laptop.
Removing laptop memory:
1. Carefully spread latches on both sides of the memory module until it pops up at a 30 degree angle.
2. Pull the memory module by the edges.
Acer Aspire 5100 has two memory slots. You can install up to 4GB RAM total. Up to 2GB memory module into each slot. You should use PC2-533 DDR2-667MHz 200pin SODIMM RAM modules.
Removing wireless card:
1. Disconnect both antenna cables. Grab the antenna cable connector with your fingers and unsnap it from the connector on the wireless card.
2. Spread latches on both sides of the wireless card same way as you did with RAM modules.
3. When the wireless card pops up at a 30 degree angle, pull it from the slot by the edges. Remove wireless card.
Removing cooling fan:
1. Remove two screws securing the fan.
2. Carefully disconnect fan cable from the motherboard.
3. Lift up and remove the fan.
My laptop had a lot of dust trapped between the fan and heatsink. This dust buildup kills normal airflow inside the cooling module and causes laptop overheating. You can blow off dust using canned air.
Here’s how you can replace thermal paste between the heatsink and CPU.
Removing laptop keyboard.
In the following steps I’ll explain how to disconnect and remove the keyboard.
1. Lift up the keyboard bezel with a flathead screwdriver as it shown on the picture below.
2. Remove keyboard bezel.
3. Remove two screws securing the keyboard.
4. Carefully lift up the keyboard, it’s still attached to the motherboard.
5. The keyboard is connected to the motherboard via a flat ribbon cable. Before you can remove the keyboard, you’ll have to unlock the connector and release the cable.
6. Carefully move the black tab about 1-2 millimeters up with your fingernails as it shown on the picture below.
DO NOT SEPARATE THIS TAB FROM THE CONNECTOR, IT HAS TO STAY ATTACHED TO THE CONNECTOR.
If you break the keyboard connector, you’ll have to replace the whole motherboard. Be careful.
7. Now you can release the cable and remove the keyboard.

@ Divyesh,
It’s not clear what issue you are facing. If the battery discharges too quickly, maybe it’s time to replace the battery.

I have this laptop since 6 months but facing a battery problem last month any idea ? how could increase battery life ?

@ german,
I don’t think you’ll be able to replace memory slot latches at home.
Here’s what you can do.
Insert memory modules into the slot. Place something on the memory modules (for example a piece of pen eraser and close the cover.
The pen eraser will apply pressure on the memory card and keep it in the right position.

Hey, I’m thinking about replacing the cpu in my acer aspire 5101 (an AMD Turion 64 X2 TL-50) with an AMD Turion 64 X2 TL-66. Anyone foresee any problems with this? (Mainly concerned about the change from 90nm to 65nm). Also I would like to replace my RAM with 4GB of Kingston DDR2 PC2- 5300 667MHz?
Cheers, Anthony

@MJ what extra memory slot? where in that picture? I can’t see it, and I can’t see it in my laptop also. The only memory slots that you can fiddle with are the ones where you put your 4 gigs in. I recently upgraded mine from 3 to 4 gigs, with 2x2gb corsair sticks, and planning on upgrading to a TL-66 or 68 CPU… that and a HDD upgrade and that’s about all you can upgrade on an Aspire 5100 series

ok, just upgraded the memory to 4 gigs, not a problem at all, but I’m trying to figure out what the extra memory slot is for. you can kind of see it in the bottom right of the “Removing wireless card” picture. anyone know what this is?
this is the wifes computer w\ vista home premium, 32 bit, but the computer shows it has all 4 gigs of memory.

PS: before i did the upgrade, i flashed the bios to version 3.13, so you may want to do that beforehand
