That's your expandable slot that will let you add more RAM if you want to beef up the system. Generally, you'll slide it in at an angle until it seats and then push it down into the laptop to lock it into place. This is by far one of the easiest and cheapest things you can do to speed up your system! Give it a whirl-RAM is cheap.

I WANT TO KNOW WHAT TYPE OF RAM, HOW MANY PINS ETC.AS WELL AS HOW MANY SPARE SLOTS MY PC HAS SO I CAN UPGRADE IT


Hi quistcris,

You can check the type of RAM on the RAM itself it if says DDR or DDR2 , or SDRAM.

You can also check this by the RAM's design , you can search online to check the different desings of RAM depending on their type.

Now as far as the slots are concerned , you need to open your cabinet and check the slots which are empty just besides the one in which you have your RAM installed.

Hope this helps ..:) Let me know in case there are any queries.

I need Help Installing additional ram on my compaq presario cq56. I have an addition 2g of ram i would like to install on my laptop and i dont know where to begin please help???


Power down your laptop and remove A/C adapter and battery. Be sure to ground yourself to prevent static electricity transfer. Small panel in the middle of bottom of laptop. Remove screws and laptop RAM is right there. Be sure your RAM matches as far values and doesn't exceed maximum size supported. There should tabs that hold the RAM in. Replace pieces of RAM. Computer should recognize the new hardware and acknowledge it when you power it up. Hope that helps..

I want to increase ram, what do I get


First, you have to find out the max of ram that you can add to your pc. Then go to the website crucial.com and run a test where it will tell you what memory and how much you can add. If you decide to purchase the memory and after you recieved , open the case and locate the empty slop where the memory is going to be install. It should be the small slots not the white big ones. Then carefully open the case from the memory and then put i on the slot of the pc. Turn the pc on and then see if it recognize it

How many slots for RAM in the motherboard?

If there are 4 slots, are the slots equally-spaced, or are they located as two pairs of slots, with a gap between the 3rd and 4th slot?

Some computers _REQUIRE_ RAM only in the 1st and 3rd slots, or only in the 2nd and 4th slots.

Some computers "beep" when 3 out of the 4 RAM slots are populated.

Some computers require the size of the RAM in the 1st slot to match the size of the RAM in the 3rd slot,
and the size of the RAM in the 2nd slot to match the size of the RAM in the 4th slot.

Does your computer "beep" when one stick is in the first slot, and the other slots are empty? How much RAM on that stick?

Does your computer "beep" when one stick is in the second slot, and the other slots are empty? How much RAM on that stick?

Does your computer "beep" when one stick is in the third slot, and the other slots are empty? How much RAM on that stick?

Does your computer "beep" when one stick is in the fourth slot, and the other slots are empty? How much RAM on that stick?

Does your computer "beep" when one stick is in the first slot and a matching stick is in the third slot, and the other slots are empty? How much RAM on those sticks?

How to install PNY OPTIMA 2GB DDR2 667 MHz memory card in lap top


Turn the computer off.
Remove the battery.
Unplug the AC adapter.
Turn the computer bottom-up.
Look for a few screws that secure a small panel.
Unscrew those screws, and remove the panel.
If you've selected the right panel, you should see your current RAM.
On the LEFT and RIGHT edges, there are small "fingers" that are holding the RAM.
Gently pull those fingers away from the RAM, and it should pop-up slightly, and you should be able to remove the RAM.
Notice that the "notch" in the middle of the RAM is slightly off-centre.
Insert the new RAM into the socket, and gently press down, until those two fingers "click" to grab the new RAM.

Depending on your "old" RAM, you may have:
* one "occupied" RAM slot (1GB), and one "empty" RAM slot;
* two "occupied" RAM slots (512MB/stick).

So, you may have to remove one RAM stick, to expose an "empty" RAM-slot "hidden" under the RAM.
Or, the "empty" RAM-slot may be visible without removing the RAM.

Or, you may have to remove one of the 512MB RAM-sticks, in order to free-up a slot for the "new" RAM.

Replace the cover-panel, and screw it in.
Reconnect the battery.
Reconnect the power-supply.

Start the computer.
Click Start
Point at My Computer
Right-mouse click on My Computer
Choose Properties
It should display your CPU-speed and the "new" amount of installed RAM.

No power at all when i try to turn it on


If the CPU (Processing unit) is not switching at all, then first thing you can check is your RAM.
Switch of the power supply and unplug the cables. Then open the top cover (or whatever your CPU has) of teh CPU and remove the RAM from its slot and install it again (place it in its slot as it is). Or if you have 2 slots for the RAM and only one RAM installed then try installing (placing) the RAM in the other slot which is empty.
Plug in all the cables and switch the power supply. This method works most of the time.
Gud luck.

How to install new ram into the 2840


Unplug the machine. On the right side of the machine you will find a cover. Remove the cover and you will find 1 open slot. The machine can take a total of 224MB (96 is built into the machine) leaving 128 available. The memory type is 100pin, 133MHz, SDRAM DIMM.

Simply click the memory into the blank slot and replace the cover.

Once completed, plug the machine back in and print a configuration page. The memory total should be at 224 once you have installed your 128MB.

Good Luck
