Check your motherboard at \nhttp://www.coastmemory.com and see what they recommend.  They have a fairly complete Motherboard lookup.

Typically, no.\n\nHowever, it needs to be compatible with your motherboard and BIOS.\n\nYou can verify that the RAM has been successfully installed by watching the bootup screens to see if the total memory has increased, and you can also goto your BIOS screen to verify the added memory as well.  As a last measure, you can check in windows to verify that the total RAM has also been increased to the appropriate amount.\n\nInstalling the RAM is relatively straightforward.  There are generally two clips on each slot for the RAM stick.  Open these clips up and place the RAM into the slot.  When placed in correctly, both clips will clamp down on the end of the stick of RAM in the little holes that are at each end of the stick.\n\nIf your RAM is not compatible, usually the boot up screens, or BIOS, will notify you, and in some cases it will ignore it and continue without error.

set to 115watt? u mean volt? .. dont mess with that switch lol ... anyway ... make sure its the correct psu for the board 24 pin or watever ... if you have a dedicated graphics card make sure power is plugged in to that if it requires it .. and also make sure there is no other "floppy" or another type connector from the psu that needs to be plugged into some spot on the board... backtrack and take everything off the board but the videocard/proc/and mem ... see if it will boot to bios settup (del or f1) ... load bios defaults if it does .. then go from there ...

Download CPU-z and check the ram.  It will tell you everything about your Motherboard and the components.

if the laptop was "off the shelf" (dell, ibm, compaq, hp, etc) you can use a wizard like the one at crucial.com to find out what your PC's memory type and maximum is. they have nearly all makes & models online, you just drill down thru a series of menus to find your particular one.\n\nif the laptop was custom-built you'll have to find out the manufacturer & model number of your board and do a little research, likely at the manufacturer's website.

I have one of these.\nRAM is RAMBUS(proprietary) - it is expensive\nCPU is socket 423-pin(outdated) - maximum 423-pin is 2 GHz \nCheck this out though, for full upgrade compatibility\nhttp://www.powerleap.com/

It all dependes on the type of ram you're looking for,\ngo to this link http://www.crucial.com/ , use the memory advisor tool, it will tell you exactly what type of memory you would need for your system. Once you have that information just go online (www.newegg.com my favorite) and order the ram you need.

You need to go to my computer, then to the control panel, then to the performance and maintenance and performance. Then click on the system icon. Almost at the bottom of the page it will tell you what kind of processor you have, such as 2.9 ghz and beside that it should say something like 512 mb of ram. There you go, I hope I really helped.

Verify it is ON in the BIOS.

just open your laptop and bring it to frys or best buy and ask for the ram you want and show them your system...just plug it in where the long boards on the main board are plugged in...it's that easy really...

Right click on my computer and click properties to get the processor type and model. Then go online and find out from the vendor site(intel or amd). and moreover u need to find out if the new processsor takes same voltage more or less and other compatibilities.

1)Battery flat\n2)Bios/cmos setup not performed properly. (all hardware not registered.\n\nIf it's an older PC also check parity/non parity setting in bios. If your system requires parity, then non-parity DRAM will not work.

It could be a number of problems. \n\nFor starters, download the program called memtest86:\n\nhttp://www.memtest86.com/#download0\n\nYou'll need a bootable CD or floppy disk. Boot the computer using the program and it will stress test your RAM and tell you if it is bad or not. Be prepared to let this program run for 10-12 hours though.\n\nIf that still doesn't work, feel free to e-mail me about this.\n\nAlso, do you know how many watts your power supply is? It should say so on the power supply label (on the inside of your case). A bad power supply (or not enough power) can cause this as well.
