"Put it in and reboot"... be sure the aptop is OFF when you add memory! Otherwise, you can damage BOTH memory and laptop! Once memory is installed there is no "trick" to get it recognized. If it is good and meets the BIOS specs, it will be recognized and registered after a cold boot.

1. Be sure the memory is inserted properly (both clips on the sides are flush with the half-moon tabs between memory and metal clips).

2. Sometimes on a memory slot that has been empty a long time (and gets a bit corroded) it is a good idea to insert the memory, remove it again and reinsert 5 or 6 times (only) to clean the contacts.

3. If number 1 and 2 have been done, and you still have this error, then there is a problem with the memory:

It may be the wrong speed (PC100 instead of PC133, etc)

It may be too LARGE for the BIOS to use (all laptops have maximum memory per slot specs that must be observed, because the laptop cannot see memory that is greater than its specified capacity.

In any case, check the manual or the website for your laptop, to get the specifications for memory type AND capacity per slot, and TOTAL memory if you have two slots -or memory soldered on board).

    Hola, la capacidad total de este modelo M2352 de eMachines y similares es de 1024Mb, NO de 1280Mb, esto es, tiene dos placas de 256Mb originalmente, una interna y una externa, juntas suman 512Mb, eMachines dice que acepta 1GB y en la web dicen que acepta 1GB, nadie define la capacidad completa, todos venden RAM de 512 y de 1GB, solo cambiando la RAM externa, si se cambia la externa por una de 512Mb mas la interna serán 768Mb totales sin problemas de reconocimiento, se puede cambiar la interna y la externa por un par de RAM de 512Mb sumando 1024Mb o 1GB como dicen sin problemas de reconocimiento, es la mejor alternativa que he deducido, por la falta de información y confusión que genera esa misma te pasas de 1024Mb totales, siempre va haber problemas de reconocimiento sin importar la marca o capacidad de la RAM a instalar.

    Sorry,my espanol is insufficient. But my Latin makes me think I understand, so I'll try:

    Some older BIOS 2-slot .laptops/desktops have quirky restrictions on mixing RAM sizes in the two slots. For example, when adding a 1024 and a 256 together, the smaller one may need to be in slot 2 (or "bank 2" as it is sometimes labeled) or vice-versa. Other BIOS may see the first bank (if it was 256) and only address RAM of 256mb after that, 12mb, meaning it would only recognize 512mb, not 1280. So beside cleaning the contacts on the RAM, you should try rearranging the order, IOW, which RAM is in the first slot, which is in the second. Of course, you must check your manual to see if it lists total/maximum RAM capacity, as you may be trying to exceed that restriction. Last, just because two different RAM chips work OK by themselves, does not necessarily mean they can work "together". If they are different speeds, many older BIOS machines will not recognize the second RAM chip..

I have a 5 in 1 card reader but nothing is happening when i put my memory stick in???

Check "My Computer" and see if the icons for the memory card slots are listed or shown as an icon each as a drive (should have 5 all together). If they're not, then check the Device Manager to see if they're listed there and the drivers are installed. If not, you'll need to re-install the drivers. Also, make sure you're putting the correct type of card into the slots - in some cases the SD slots cannot accept the SD-HD types even though they're the same size.

Nothing happens when I insert XD card into pc

That's because there is either a defective card slot or the driver for the card slot is defective or not installed at all

Was this card slot (XD card slot) working before?

If it was, then you must reinstall the memory card drivers.

If after the driver reinstallation does not solve this issue, then you may have a broken memory card reader and needs to be replaced.

Or you can go around the problem by geting a separate card reader for Xd cards.

I hope this helps you :)

Inspiron 2200 Memory Module not recognised

Are you sure its the correct speed/type of RAM? According to Google your laptop takes PC2700 DDR RAM, ensure you are using this in both slots to avoid problems. If you have it fully inserted into the slot and nothing happens when you swtich it on then the laptop doesnt like that type of RAM and you'll need to change it.

    Memory Card Drive

    You need to ensure that your Computer has the relevant Drivers Installed. i.e Toshiba Laptops have a specific Driver, Solely for MSSlots, 1 as the program, and another program to Format.
    Also check that the memory card, appears in the My Computer Window, As Drive E:/ Or F:/ et,c. assuming that C:/ would be your hard-drive. D:/ Or D:/ And E:/ CD/DVD Drives. Then any additional devices such as F:/ G:/ H:/ I:/ et,c will be card-readers et,c.
    Finally is that the computer understands the Actual Format of the SD Memory Card. FAT/FAT 32 et,c.

    Hope this points you, towards solving your problem.

    Reg mmc card reading

    Normally you'd just be able to open My Computer, and plug the card in to the built in slot, and it would pop up as the next available drive letter. If the internal slot is missing or inoperative, you could buy a cheap MMC to USB adapter, plug the card into the adapter, and the adapter into a USB slot.
