Call BIOS: Here's how

If you have to call up the BIOS because of problems with your system, you will quickly notice that this is not always that easy. The time window is very small and the number of possible buttons is very large. We'll tell you how to get into the BIOS.

How do I call the BIOS?

To open the BIOS, a certain key must be pressed when the computer starts. Switch on your computer, you will first see a few notes and possibly also the manufacturer's logo. At this point, the button must be pressed (preferably several times) so that you get the right time. You can read which key you need in the next paragraph.

Depending on the manufacturer, the BIOS is called using a different key or key combination. The following list shows the most frequently pressed keys in descending order:

1. The "Delete" key is most often used.
2. It is often also the "F1", "F2", "F8" or "F10" keys.
3. The tab key is rarely represented. You will find this on the far left of the keyboard, printed with two arrows.
4. If none of these keys work, press "Ctrl" + "Alt" + "Esc" or "Ctrl" + "Alt" + "S" at the same time.
