Are you trying to Upgrade the Memory ?. .then all you have to do is take of the screws that have a small picture of a Memory chip next to it. and pop off the small lid to reveal the Memory Bank. You may want to use a really thin flat head to pry the cover off.

If you are trying to take apart the whole back cover for whatever reason, There is a little "clip" type things for a lack of a better word. Just kind of try and get a finger nail in there and move it around. It'll "snap" out of there. And be careful, there is a thin plastic peice that goes around the DVI connector at the back, and if you're pulling ******* it to get it out, you run the risk of snapping it. But no, nothing special, just try to not break it Acer Extensa 5420 laptop memory upgrade - wink.gif

Just be gentle and pull UP if its kind of Hanging where the windows Vista sticker is.

good luck,

How to install memory stixs


In an Acer Extenza 5420 series of Notebook PC?

Well you came to the right place

Here have a seat, and let me show you;

1) Remove ALL power. Remove the AC adapter (Charger), and Battery.

2) Here is a Bottom view of your laptop,

http://www.ebay.com/itm/Acer-Extensa-5420-Case-Bottom-15-4-Black-Cover-Speakers-Original-Genuine-Laptop-/170983023419?pt=US_Computer_Cases&hash=item27cf61e33b

Bottom left corner shows the Battery has been removed.
Remove the large panel above it,

http://www.ebay.com/itm/Acer-Extensa-5420-5520-Hard-Drive-RAM-Memory-Bottom-Cover-Door-60-4T305-002-/190741766831?pt=LH_DefaultDomain_0&hash=item2c691862af

Looks to be 6 Philips head screws to remove.
The panel lifts up on the LEFT side. There are TABS extruded from this large panel, which go into the Base Enclosure, (Bottom Cover), on the Right side.

From the Specifications on Acer's Support website,

http://support.acer.com/acerpanam/notebook/0000/Acer/Extensa5420/Extensa5420sp2.shtml

,it states;

System Memory: -> Up to 2GB of DDR2 667MHz memory; upgradeable to 4GB using two SO-DIMM ram memory modules.
(Dual-channel support)

From what I can see, looking at the motherboard by itself; there are TWO ram memory slots,

http://www.ebay.com/itm/Acer-Extensa-5120-5420-7120-7420-TravelMate-5220-AMD-Motherboard-MB-TKP01-002-/350455821339?pt=Motherboards&hash=item5198cb741b

Towards the Top you see the White processor socket. Upper corners are cut off, and there is a single screw in the top/middle.
Right above it are two white Ram Memory slots.

EACH ram memory slot will support (Use) 2GB of DDR2 at 667MHz.

2GB = Amount
DDR2 stands for DDR2 Sdram, and is it SO-DIMM to fit in a laptop.
667MHz stands for 667MegaHertz.
The frequency rate ('Speed') that the Ram Memory operates at.

The TOTAL amount of ram memory for the laptop is 4GB.
That means you can use two modules, ('Sticks') of DDR2 Sdram at 667MHz.
Or also stated as PC2-5300.

Just make SURE it is SO-DIMM, or you will be getting the larger DIMM ram memory used in a desktop computer.
An example of SO-DIMM,

http://en.wikipedia.org/wiki/File:1GB_DDR2_SO-DIMM.png

Note the Side Notch on Each side.
The half-moon cutout.
Note the Locating Notch on the Bottom.

Also;
Everywhere on the Ram Memory module, EXCEPT the gold plated contact pins at the Bottom; is the BODY.

The Body is coated with a see-through protective plastic.
Handle the Ram Memory module by the Body.
Refrain from touching the gold plated contact pins.

[WORK on a table. {Or workbench} DO NOT work on a bed, couch, or directly on a carpet floor! High areas of Static electricity.
Static WILL fry out, (Short Circuit) computer hardware components]

If you have two Ram Memory modules, one will be stacked on top of the other one. You remove the top one first, then access the bottom one.

To remove a ram memory module, simply ease the spring clips on either side -> OUT.
Out away from the Ram Memory module.
This action takes the 'Bumps' on the Spring Clips, out of the Side Notches on the Ram Memory module.

DO NOT get carried away. Just ease one spring clip out, then ease the other one out. You can bend the spring clips if you are too rough.
When both spring clip 'bumps' are out of the way, the Ram Memory module will spring up slightly.

Remove AT THAT ANGLE.

Slide the Ram Memory module out, at the same slight angle, (30 degrees?), that it just popped up to.

IF you lift the Ram Memory module straight up, you WILL damage the gold plated contact pins on the bottom of the Ram Memory module; and the contact pins in the Ram Memory slot.

To install a Ram Memory module, look at the location of the Locating Notch on the Bottom.
This aligns with a Locating Lug, in the bottom of the ram memory slot.
ONLY goes in one way.

Locating Notch aligned with Locating Lug, slide the Ram Memory module in, in the SAME slight angle it came out at.
Make sure the gold plated contact pins of the Ram Memory module, are well seated in the ram memory slot.

(Ram Memory module is pushed in tightly, in the Ram Memory slot)
Then press down on the tilted up side, until the spring clips lock in place.

Here is a video demonstrating the above, but NOT your laptop,

http://www.youtube.com/watch?v=MbPaR1Ci-Ug

IF, you are ONLY installing ONE Ram Memory module, it MUST go in Slot 1. Also known as DIMM 1.

The Processor (CPU) reads what is in Slot 1 -> F-I-R-S-T.

Know this;
If you are using the regular Windows XP Home, or Pro; it is the 32-bit version.
If it is the Windows XP Pro 64-bit version, it will state so.
Either on the body of the laptop, or go to System Properties.

[Left-click on Start > then Right-click on My Computer.
Left-click on Properties at the bottom of the drop down list ]

Windows Vista 64-bit will state so also.

Point?
IF you have a 32-bit Operating System, your laptop will ONLY recognize about 3.2 to 3.5GB of ram memory; if you have 4GB installed.

Takes a 64-bit Operating System to recognize all 4GB.

For additional questions please post in a Comment.

My right speaker is making a rythmic clicking sound. Music and other sounds can't be heard. I've checked on control panel and all seems ok I also did a system restore. any ideas how to resolve this?...


Possible but I don't think it very likely. You can try removing and reinstalling the driver but I believe it's the speaker itself. You can get a set on Ebay for about $10.00.

MEMORY UPGRADE ON ACER TRAVELMATE 5720G


Acer's support isn't the best. IMHO But go to their support site anyway and look up your laptops manual (there should be instructions on upgrading your RAM there). I did find that your machine will accept up to 4GB of RAM 2 X 2GB sticks. There should be a door or port (for easy user RAM upgrading) that is being overlooked, but again it is an Acer.
Good luck.
