How to enter BIOS on a Lenovo laptop: what you need to know and what you don't need to do?

BIOS in laptop

Most of us, using computers or laptops, do not think about how these electronic devices work. The developers of modern software have created operating systems with an interface that is understandable for everyone. But sometimes there come 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 a computer and controls its operation is the BIOS. He 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 random access memory. At the slightest failure, the BIOS will identify the problem and make it possible to fix it. Therefore, without his "consent" to make any changes in the computer will not work.

Primary bootloader

Login to Lenovo BIOS

Translated from English, the abbreviation BIOS stands for "basic input-output system". This is a set of microprograms that control the operation of the processor, video adapter, RAM, hard disk and connected devices.
It was first used by specialists from IBM and called the primary bootloader. Its main functions are testing and tuning equipment, as well as loading the operating system. Considering that the BIOS is responsible for initial loading, all its software elements must be available immediately after turning on the power, so they are not stored on the hard drive, but written into the memory of one of the microchips located on the motherboard. This microcircuit even has its own constant power supply from the 5V element, also located on the "motherboard".

BIOS types

Bios in a laptop is no different from a computer. There are three main types of primary loaders today:

  • AWARD;
  • AMI;
  • UEFI.

The first two do not differ in anything special, except for the type of menu, they have an exclusively English interface and key control. They are used on almost all brands of computers and laptops. UEFI is a completely new kind of BIOS, with a graphical shell and the ability to control using the "mouse". It has been used since 2011 only in the latest models of computers and laptops. More experienced users know that it is not difficult to enter the primary bootloader on a personal computer, just press the F1 or F2 keys after turning on the power, as on a Lenovo laptop. It is also easy to enter BIOS on laptops from other manufacturers, however, without having a manual in hand, you will need the name of the model and modification.

Considering that the electronics market today is filled with Chinese laptops of various brands, the algorithms for their bootstrapping are different. Logging into Lenovo BIOS, for example, is fundamentally different from this procedure on Toshiba or Asus, where the F12, Dellete or Esc keys are used.

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

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

What shouldn't you do yourself?

Now that we know how to enter 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:

  • Do not plug in and unplug the laptop while in the BIOS.
  • You should not experiment with changing the settings, in particular, overclocking the processor or video card yourself. Such an operation, with the slightest mistake, will damage the devices.
  • It is not recommended to change the system date. This will lead to a conflict with the operating system.

Having basic knowledge of using computer programs and observing these simple rules, you can easily adjust your laptop without any problems.
