One of the options you can ask if your notebook or laptop starts running slow is to change the processor. However, you must keep in mind that it is much more complicated than with a desktop PC. Moreover, there are computers on which this change is impossible since the micro is directly soldered to the motherboard.
You can change the micro thinking you will solve all your problems and end up spending a lot of money and not reaching benefits you seek. A good way to deal with performance problems is to try to locate the device which is suffering so as not everything in a PC is the processor
Slowness to play. 3D games are increasingly demanding. If you have problems it is best to change the graphics card. A good strategy if you are very jugon, is to invest every year or year and a half, money on good card.
Continuous blocks. The team goes as jumps.
overall sluggishness. If the computer is simply slow and are willing to make an investment in it. It is best to add a good SSD. It is very important in laptops, because not only you will increase its speed but also provoke a large energy savings.
Always keep in mind that physical problems such as heat affects performance. If your computer shuts down completely you need to clean all the ventilation holes. Any PC desktop or laptop includes mechanisms that turn off the equipment if the temperature rises too.
If you have decided I would follow the following steps
Check the website editor. No one better than this may give you the information whether or not you can change the processor and how. You can even write an email to your mail technical support. The most common assemblers are Sony, Toshiba, Acer, Asus, Samsung, etc.
Check the socket. If the socket is directly BGA forget about any change of processor without changing the entire motherboard as these is welded. In addition your new micro, if you will not change the motherboard should be able to use the same socket.
Check the features of your motherboard. You must be able to accept the new micro. In some cases, if the micro is more modern, an update of the BIOS may be necessary.
Check the features of your RAM. To see if it is compatible. You have to keep in mind that in many current processors the memory controller is inside and not all micros are compatible with all the memories.
Consumption. The manufacturer of micro uses the TDP to tell the assembler how much is the maximum power that theoretically the processor will dissipate. The editor therefore creates the whole structure based on this number. You can not therefore put a microphone on a laptop designed for a much lower TDP as surely end up burning.
Processor purchasing conditions. Make sure you can return the processor if not serve. There is nothing sadder than spending money and get nothing in return.
Use common sense. To see if you can not continue. Be careful as you are touching the guts of the laptop and you can end up spoiling.
