As on the laptop "Lenovo" enter the BIOS: what you need to know and what not to do?

Most of us, using computers or laptops, do not think about how these electronic devices work. Developers of modern software created operating systems with a clear interface for all. But sometimes there are times when the most incompetent user has to deal with such concepts as reinstalling the "operating system" or setting up the system. The basis that connects all the elements of the computer and controls its operation is the BIOS. It is responsible for everything from the temperature of the processor and the correct loading of the OS and ending with the maintenance of programs when accessing the hard disk and the online storage device. At the slightest failure BIOS will determine the problem and will allow it to be fixed. Therefore, without his "consent" to make any changes in the computer does not work.

Primary loader

In English, the abbreviation BIOS stands for "basic input-output system". This is a set of microprograms that monitor the operation of the processor, video adapter, RAM, hard disk and connected devices.
For the first time it was used by IBM specialists and was called the primary loader. Its main functions are testing and setting up the equipment, as well as loading the operating system. Given that the BIOS is responsible for the initial boot, all of its software elements should be available immediately after power on, so they are not stored on the hard drive, but stored in memory of one of the microchips on the motherboard. This chip has even its own constant power from the element 5V, also located on the "motherboard".

Types of BIOS

The bios in the laptop is no different from the computer one. Today there are three main types of primary loaders:

  • AWARD;
  • AMI;
  • UEFI.

The first two are nothing special, except for the menu, they do not differ, they have an exclusively English interface and key management. Applied on almost all brands of computers and laptops. UEFI is a completely new kind of BIOS, with a graphical shell, as well as the ability to control with the mouse. It is used since 2011 only in the latest models of computers and laptops. More experienced users know that it's not hard to enter the primary bootloader on a personal computer, just after turning on the power, press the F1 or F2 keys, like on a Lenovo laptop. Log into the BIOS on laptops from other manufacturers is also easy, but without a manual on the hands, you will need the name of the model and modifications.

Given that the electronics market is now flooded with Chinese laptops of various brands, the algorithms for their initial download are different. Logging into the BIOS of Lenovo, for example, is completely different from this procedure on Toshiba or Asus, where the F12, Dellete or Esc keys are used.

How on the Lenovo laptop enter the BIOS?

Laptops of this brand have gained wide popularity in our country. Acceptable price and reliability have made them indispensable for both work and entertainment. Of course, sometimes you have to make the necessary settings or reinstall the operating system. But not everyone knows how to enter the BIOS on Lenovo's laptop. This is due to the variety of models, most of which, like the G500, G505, G510, B590 and V580c, allow you to go into the recovery environment or BIOS by pressing the F1 or F2 keys. On some models released before 2010, you need to combine several buttons, for example Ctrl + Alt + Ins.

If you press and hold F12 during system startup, the Quick Boot menu (BIOS sub-section) appears, allowing you to set the boot order and select the appropriate resource for it (HDD, CD-rom or USB).

What should not you do on your own?

Now that you know how to enter the BIOS on a Lenovo laptop, before making any changes, it will not be superfluous to learn a few rules so as not to disable it:

  • You can not connect the laptop's power and disconnect it while in the BIOS.
  • Do not experiment with changing the settings, in particular, independently to "overclock" the processor or video card. Such an operation will, with the slightest error, cause damage to the devices.
  • It is not recommended to change the system date. This will lead to a conflict with the operating system.

Having basic knowledge in using computer programs and observing these simple rules, you can easily configure your laptop without special problems.
