In other laptops the CPU is soldered on the motherboard and is non-replaceable; this is nearly universal in ultrabooks. In the past, some laptops have used a desktop processor instead of the laptop version and have had high performance gains at the cost of greater weight, heat, and limited battery life, but the practice was largely extinct as of Unlike their desktop counterparts, laptop CPUs are nearly impossible to overclock.
A thermal operating mode of laptops is very close to its limits and there is almost no headroom for an overclocking—related operating temperature increase.
The possibility of improving a cooling system of a laptop to allow overclocking is extremely difficult to implement.

Graphical processing unit[ edit ] On most laptops a graphical processing unit GPU is integrated into the CPU to conserve power and space. This was introduced by Intel with the Core i-series of mobile processors in , and similar accelerated processing unit APU processors by AMD later that year.
Prior to that, lower-end machines tended to use graphics processors integrated into the system chipset , while higher end machines had a separate graphics processor. In the past, laptops lacking a separate graphics processor were limited in their utility for gaming and professional applications involving 3D graphics, but the capabilities of CPU-integrated graphics have converged with the low-end of dedicated graphics processors in the past few years.

Higher-end laptops intended for gaming or professional 3D work still come with dedicated, and in some cases even dual, graphics processors on the motherboard or as an internal expansion card.
Since , these almost always involve switchable graphics so that when there is no demand for the higher performance dedicated graphics processor, the more power-efficient integrated graphics processor will be used.
Most laptops have two memory slots, although some of the lowest-end models will have only one, and some high end models usually mobile engineering workstations and a few high-end models intended for gaming have four slots. Laptops may have memory soldered to the motherboard to conserve space, which allows the laptop to have a thinner chassis design. Soldered memory cannot be easily upgraded. Internal storage[ edit ] Traditionally, laptops had a hard disk drive HDD as a main non-volatile storage , but these proved inefficient for use in mobile devices due to high power consumption, heat production, and a presence of moving parts, which can cause damage to both the drive itself and the data stored when a laptop is unstable physically, e.
With the advent of flash memory technology, most mid- to high-end laptops opted for more compact, power efficient, and fast solid-state drives SSD , which eliminated the hazard of drive and data corruption caused by a laptop's physical impacts.
Some very compact laptops support even smaller 1. For SSDs, however, these miniaturization-related trade-offs are nonexistent, because SSDs were designed to have a very small footprint.
SSDs feature a traditional 2. SSDs have a higher data transfer rate, lower power consumption, lower failure rate, and a larger capacity     compared to HDDs.
However, HDDs have a significantly lower cost. Most laptops can contain a single 2. Some laptops support a hybrid mode, combining a 2. Some laptops may have very limited drive upgradeability when the SSD used has a non-standard shape or requires a proprietary daughter card.
Many laptops also incorporate a card reader which allows for use of memory cards , such as those used for digital cameras , which are typically SD or microSD cards.
This enables users to download digital pictures from an SD card onto a laptop, thus enabling them to delete the SD card's contents to free up space for taking new pictures. Laptop optical drives tend to follow a standard form factor, and usually have a standard mSATA connector.
It is often possible to replace an optical drive with a newer model. In certain laptop models there is a possibility to replace an optical drive with a second hard drive, using a caddy that fills the extra space the optical drive would have occupied.

A touchpad also called a trackpad , a pointing stick , or both, are used to control the position of the cursor on the screen, and an integrated keyboard  is used for typing.
An external keyboard and mouse may be connected using a USB port or wirelessly, via Bluetooth or similar technology. After you become comfortable with power electronics the logic session follows.
It is an intensive coverage into the intricate details of chip-level service of the laptops. This involves detailed circuit tracing , signal analysis , replacement of SMD devices and all the tips and tricks our service engineers acquired from the years of experiences. Chip Level Training, Training Manual, Service Guide, Tutorials,Tips Service Technicians entering into the Laptop training course must have experience in the following disciplines must be comfortable in using desktop systems and peripherals must have an above average knowledge about all the internal components and operation of the system comfortable with installing and managing various operating systems.
