Laptops are the tiniest computer that can do exactly the same stuff as a normal desktop computer. Because of the very limited space inside a laptop case, the manufacturers can't use a desktop computer's CPU in their laptops, so they have to go proprietary. If you havn't heard this before, it means non-replaceable, or non-interchangeable. This means you can't whip out the old CPU and whack in a new one, because the hardware configuration would be different. Although most manufacturers (mostly the brand name ones) choose to go with proprietary CPUs, some stay with universal hardware configurations. If in doubt, research the laptop you have and see if you can get hold of a faster CPU. If you can't, just get a new laptop!
A laptop processor is a CPU optimized for Laptops. One of the main characteristics differentiating laptop processors from other CPUs is low power consumption.
A dual core laptop is a laptop that uses a processor that has two cores. Having two cores allows a laptop to perform more powerful functions and speed than if it had a single core.
check the cpu, make sure it is dual core.
unlikely most laptops CPU are soldered to the board either get a new one or send it back for an upgrade
A desktop is larger and sits on a desk. A laptop is smaller and portable; you can carry it with you.
Laptop processors can be purchased from the following retailers: "Newegg", "eBay", "Whirlpool", "IBM Hardware", "Acs Parts", "Impact computers", "Computer shopper". Most of these are refurbished processors as there is no retail market for changing one's CPU.
CPU protection is one who protect the CPU. and the one who destroy the CPU also is the one who protect the CPU and the one who destroy the CPU is the one who protect the CPU and the one who destroy the CPU is the who protect the CPU and the one who destroy the CPU is the one who protect the CPU and the one who destroy the CPU is the who protect the CPU and the one who destroy the CPU is the one who protect the CPU and the one who destroy the CPU is the one who protect the CPU.
For a laptop battery there are no 90W or 65W but there are 90WH and 65WH. If you mean this so you can replace a 90WH battery with a 65WH battery but the 65WH one can't last longer than the 90WH one at the same load.
A laptop functions exactly the same way as a desk-top computer - except that allthe components are contained in one unit iinstead of having a separate keyboard, CPU and monitor.
One can buy a cheap laptop either used or new. If it is used, it is probably best to assume that one year of good service would be the norm, unless the laptop was just recently bought. For a new cheap laptop, expect to pay around $500. But don't expect to get a "core" CPU, one that operates as two or more CPUs. Core CPU laptops cost over $500. A budget, cheap laptop should cost $400 or less. It should have wireless and Ethernet modems and at least a good 100GB or 200GB hard drive.
Whats the problem? If you can't identify it, buy a new one.
There are many laptops that are using the i5 CPU. One can purchase them from various retailers and manufacturers like Amazon, eBay, Medion or Lenovo.
