Go to Crucial Memory's site and run the "scan my system" option. It will tell you the exact amount of memory your computer supports, how many slots are empty and what is in the occupied slots. The link is www.crucial.com

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.

Want to increase speed


You can upgrade the RAM providing you have the slots available.
The maximum supported RAM in windows 7 is 4GB. You will find the serial number on the bottom of the laptop, possibly in the battery bay. You can use the following scanner to check the required RAM.

Can i install windows 7 on my acer extenza 5620?


Yes you can, but please note that the laptop has shared video memory so if you will get a low rating index on Windows 7 you will need to upgrade the RAM (it supports up to 4GB) in order to allocate more RAM to the video card.

My acer extensa 4420 5239 turn on for a few second then turn off by itself no video and sound


There is a hardware issue... Could be ram if so you can fix yourself.
Take out one piece of ram at the bottom of the unit... If the problem still occurs then take out that ram and put the other piece back in and see where that leads you

Problem with upgrading my acer extensa 5620z memory to 4GB


Hi there.
I recommend you get another stick of SODIMM to replace what seems to be the faulty stick.
If you are using XP or Vista X86 (32bit) then the system will only recognize 2.8 - 3GB of memory, only 64bit operating systems recognize the full 4GB.


Good luck ad thanks for using FixYa!!
