Few computer users know that the first program to run when the PC is BIOS.In this basic input / output system (that's right, this stands for the name) contains a number of software modules, through which the computer carries out a self-test and initialization of the installed equipment, and then passes control to the device operating system.With a simple interface, called BIOS Setup user can customize the data base software modules.But for this he will first need to know how to enter the BIOS.
If virtually all desktop computers manufacturers have reached a certain agreement and the BIOS interface is called the same button (usually by pressing «Del» or much less «F2»), the laptops situation is much more complicated.Each manufacturing company often develops very simple software for their devices.So the answer to the question of how to enter the laptop BIOS, often depends on the brand of laptop.Each manufacturer provides such information to the user in different ways.The most common clue about how to enter the BIOS appears on the screen when you turn on the laptop.If it does not, we can use the table below.
This tip will help the user understand how to enter the BIOS on the laptop of a manufacturer:
«Esc» - almost all laptops «Toshiba» (to exit from the menu that will be necessary to press «F1»);
«F1» - most laptops issued by companies «Lenovo» and «IBM», as well as some models of the companies «Dell», «HP», «Gateway» and «Packard-Bell»;
«F2» - the vast majority of laptops manufacturing «Asus», «Acer» and «RoverBook»;
«F3» - sometimes runs the BIOS from laptops «Sony» and «Dell»;
«F8» - allows you to enter the BIOS on some laptops brands «Dell» and «iRu»;
«F10» - used in laptops «Compaq» and «Toshiba» provided at the moment of clicking on the top right corner of the screen blinking cursor;
«F12» - some models «Lenovo», as well as other producers;
«Ctrl + F2» - many models of «Asus», issued more than five years ago;
«Ctrl + Alt + Esc» - sometimes found in laptops brand «Acer»;
«Ctrl + Alt + S» - can often be found in laptops little-known firms.
All self-respecting manufacturers to find out how to enter the BIOS of that particular laptop model can be very simple - just enough to visit the official site and view detailed instructions.For notebooks little-known firms (if none of the above options did not help), you can also try a combination «Ctrl + Ins», «Ctrl + Alt + Enter», «Fn + F1», «Ctrl + Alt + Ins» or «Ctrl +Alt + Del ».
Unlike stationary PC, laptop BIOS offers a user a few extra options:
- advanced password management infrastructure;
- work with the touchpad TouchPad / TrackPoint;
- several options to expand the screen - if the display resolution lower than the physical resolution of the matrix, it can be a little stretch or reduce the image on the screen;
- calibration and fine-tuning of the battery;
- the BIOS Setup of your laptop user can view the serial number of the device, the motherboard and the hard disk.
But do not rush to change something in the settings as soon as they learned how to enter the BIOS.Despite the possibility of more modest compared with stationary PCs in terms of "fine tuning" ("acceleration" of some parts of the device, the supply voltage, etc.), such interference can lead to permanent reboot the laptop, or even failure of some of the details.You first need to pay attention to the study of each item bios and its impact on the operation of the entire device.
For starters, you can change the BIOS values for one and see how it affects the power.If you drop in performance or an unresponsive laptop it is recommended to immediately restore all the items by default.
