Re: adding ram

You should only have to remove one of the screws on the bottom of the laptop, should be the one right in the middle of the underside, Just take out that one maybe two screws on the back you will see the small memory modules, You will have to press the little white tabs on both sides of the old modules just move both to the outside of them and one at a time will pop up and just pull them back so that they slide out easy and replace with the new ones make sure that they click down into place firmly alla and all its pretty easy If you have any ?s email me and i will be glad to help you out any way I can. Thank You for your question.. Bear001

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,

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

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,

,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,

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,

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

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.


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,

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.

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.

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.

Add more ram

To add ram - look on the back of the lap top. You will see some screws that are holding down a little door. There may be two of these. Remove the screws on the ram cover and remove ram cover

Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} Ram slots are stacked. you have to remove the top one first.
1- press the buttons on the sides of the ram chip, and then it will pop up and towards you.
2- 2- pull this ram upwards and out
3- from there, you can take out the other chip, if there is one, or you can start installing.
4- installing the new ram chips is just as easy
5- line up the slots in the chip, then push it in as far as you can without breaking it.
6- then push it down so that you hear it click on both sides, and doesn't budge.
7- Repeat using the top chip.
This should do it –
I hope it helps- please rate me – thanks

Need original manufacturer settings

Hi there.

When you turn the laptop on, I believe you get an ACER logo, press Alt and F10. This should start the recovery program.

If you need any more assistance, just ask, I'll be glad to help.
