My brand new Lenovo computer is also doing this. I haven't seen a response to this, what was the answer? Did anyone have a solution?
Traditionally they were miniaturized and adapted to mobile use, although desktop systems increasingly use the same smaller, lower-power parts which were originally developed for mobile use. The design restrictions on power, size, and cooling of laptops limit the maximum performance of laptop parts compared to that of desktop components, although that difference has increasingly narrowed.
This restriction is one of the major differences between laptops and desktop computers, because the large "tower" cases used in desktop computers are designed so that new motherboardshard diskssound cardsRAMand other components can be added. In a very compact laptop, such as laplets, there may be no upgradeable components at all.
Models with LED-based lighting offer lesser power consumption, and often increased brightness. Having a higher resolution display allows more items to fit onscreen at a time, improving the user's ability to multitask, although at the higher resolutions on smaller screens, the resolution may only serve to display sharper graphics and text rather than increasing the usable area.
External displays can be connected to most laptops, and models with a Mini DisplayPort can handle up to three. Typically, laptop CPUs have two processor cores, although 4-core models are also available.
For low price and mainstream performance, there is no longer a significant performance difference between laptop and desktop CPUs, but at the high end, the fastest 4-tocore desktop CPUs still substantially outperform the fastest 4-core laptop processors, at the expense of massively higher power consumption and heat generation; the fastest laptop processors top out at 56 watts of heat, while the fastest desktop processors top out at watts.
Many laptops have removable CPUs, although this has become less common in the past few years as the trend has been towards thinner and lighter models.
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 inand 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 chipsetwhile 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. Sincethese 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.
Nvidia Optimus is an example of this sort of system of switchable graphics. 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 storagebut 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 SSDwhich 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 cardssuch as those used for digital cameraswhich are typically SD or microSD cards.Toshiba 43LDB Operating Instructions Manual.
