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.

Need to know how to install additional ram

There is a little door under the laptop, with a couple screws.
If you open it, you will see the ram modules.

They are easy to remove and replace with additional (if empty slot available) or upgraded ram.

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..

How to upgrade from 512mb RAM to a higher GB?

Check if there are RAM slots marked on the bottom of the laptop, they are generally a panel with some bolts and an icon of a chip, kinda like this. I do recommend however to go to a specialist for the upgrade and not DIY it at home. Also, it is quite possible, depending on the model, that you do not have a RAM extension slot at all and in that case you're stuck with what you have.. unless you buy a new computer that is. In any case I'd advise you seek a professional that can tell you if you can and if you should upgrade and give you some options. Hope I helped!

No image on monitor, only beeps four times

Four beeps means Faulty RAM.
1. If u know how to open and set RAM, then open ur RAM by simply opening the RAM cover on the backside of ur laptop, there wil be 2 screw, u have to open it first, then just remove RAM by pressing both side locks.
2. After removing the RAM, clean it with news paper aur any clean cloth.
3. Place the RAM again to its slot. (remember the cut mark of slot, don't try to place hardly)
4. After placing RAM, tight screws and then start the laptop again.
5. If the beeps are coming again then change the RAM. (If it is in warranty u can replace)

I purchased 1 g of memory to add to my laptop. I am not able to do anything with the laptop due to the lack of memory. I can't afford to have someone add the memory and must do it myself. What can you do...

It's easy to add the memory yourself. Memory has a small compartment in the middle, you only have to unscew one screw to have access to it, the screw circled in the image below. When you put the memory in you have to put it to a 45 degree angle and press it down until it clicks in.

Then you close the cover and start the laptop. If you get a beep it means the momery is not installed properly.

How can i disassemble my k40in notebook so i can upgrade the ram

If you just want to add RAM modules to your laptop, a complete dis-assembly is not necessary.

  1. Place your laptop in a way that the rear part or the bottom part is exposed.
  2. There are certain compartments found at the back part. Look for the small compartment where you can see a RAM Module "icon", which means that beneath or covered inside are RAM Modules.
  3. Simply unscrew the cover (compartment) to reveal the RAM.
  4. Look for the extra or empty RAM slot where you can insert the additional RAM module to boost your laptop's performance.

Can not find second ram chip

Remove both pieces of ram (mark them with a felt tip marker so you know which one is which), and clean the contacts on the ram and the slots with a pink pencil eraser. Be gentle though, you don't want to remove the gold on the contacts, just remove the oxidation and make 'em bright again. You can shape the eraser to fit the slot with a sharp knife - and be sure to remove the eraser debris from the slots with a soft brush (dry toothbrush is good) . If still no good try this:
  1. Remove both pieces of ram.
  2. insert the second piece of ram in the first slot (leave the other slot empty) If the second piece of ram is detected, then the ram is good, and the second slot is likely the problem. If the ram is not detected, then the second stick of ram is the problem. Confirm this by putting ram stick 1 into slot 2. If the known good stick of ram (1) doesn't work in slot 2, then the slot is dead. If this is the case, get a larger stick of ram for slot 1. Let me know if this helps or not.

Upgrading RAM on Acer Travelmate laptop - can't see existing RAM module

Safely depends on your knowledge of computer hardware. If you know what you re doing, you can take the whole thing apart and replace any non-chip component you want (processor, drives, cards, etc). If you really look you can find sites that will tell you how to take apart a computer. If you don't know what you are doing and your current configuration works well, I would leave it for now, and wait until you can find someone that can help. Hope this helps.
