I am a computer enthusiast, and have in the past 21 years. Now I have a number of computer related experience have made, most of which have taught me what it means to successfully deal with an upgrade of the computer. Because of my long experience with computers, I thought I would share some information here, because you can not apply to the use of RAM in your desktop, laptop, notebook, sub-notebooks or netbooks (like everyone else) and vice versa.
For those seeking a quickReply
very limited memory of the computer desktop cases may unfortunately is not only used laptops and laptop-memory can not be used in desktop computers inside There are some reasons for this and find out why I recommend you read more answer below . However, it should be the time it takes, just remember, laptop memory upgrades can not be reversed, and a memory upgrade desktop versa, because they are of variable size.
Forthose who have a longer response (recommended)
To understand why you can not use all memory of the laptop computer desktop and vice versa, first remove the unique feature of this rule is broken. In the days very old laptop until they appear in memory that came to SIMMs are used, otherwise as Single Inline Memory Module, are known. These were used, in fact, the desktop computer at the same time, both in 30pin or 72 pin configurations.As portable computers entered the mainstream, and therefore less of a brick and a more mobile, this aspect to change.
Mainstream laptops were used as a variation on the same computer memory in desktop computers. For this reason, it is for you stumbling on behalf of the common model PC2100, PC2700, PC3200, PC2-3200, PC2-5300 and most recently PC3-8500, etc., which can also be found in the memory of the computer desktop. The major reason behind the "why" is that laptopssimply a subset of personal computers. They are designed to use the same principles, therefore, a set of common technologies. The "why" behind why you're doing a set of common technologies, a topic on Their own, but now the best way for you is that, following this, are made compatible and think that you can run the same software and hardware use very similar.
So what are the differences you may ask? From the above we know that the keyDistinction is not in memory technology. PC2100 DDR memory in laptops is exactly the same as DDR PC2100 memory in desktop computers, and the same goes for PC2 5300 DDR2 PC2-5300 DDR2 memory and laptop-desktop, etc. The difference lies in the memory module themselves. If you remember from above, use laptops very old memory came to 30/72pin SIMM as desktop back in the day. Memory laptop is available in Modern DIMMotherwise known as dual-inline memory modules. This is not to find the most important difference, we introduce the SO-DIMMs, which are the wide range of portable DIMMs.
SO-DIMMs are mini-versions of the DIMM. Depending on the storage technology that has on board (they are soldered to its circuit - Printed Circuit Board) will vary a bit 'in size and number of pins they have. For this reason, it is simply to say, other than desktop memory upgrades laptopmemory upgrades simply watching them, but also understand why they are not used in desktop computers. Why SO-DIMM fewer pins are, for example 144pin 168pin Vs in the case of laptop / desktop SDRAM memory, are smaller and therefore more suitable for laptops. Incidentally, Since laptops are limited interior space, which explains why SO-DIMMs have been invented and goes so far to explain why some laptop computers can now be so subtle and yet so powerful.
InSummary
I hope the above is helpful, and can now explain this to your friends and colleagues would never in doubt. Finally, we want a quick summary. Only very old laptop uses the same memory for desktop computers. It 'was because they are large and heavy, and space considerations within the laptops were not really a problem. For mainstream notebooks was, and then the space has become a problem have been forced to invent computer designers SO-DIMM's. These are clearlysmallest desktop-DIMM and SIMM now old and have fewer pins. Despite these differences, the storage technology employing identical to those of desktop computers. If you compact all together above to respond with a link to it would be easy, these slots - memory upgrades for notebook computer desktop does not work, because they are smaller, and therefore is not suitable for larger memory.
