Well, i write this article to reply someones question about his computer a momment ago. He ask me, "Why my computer always ask for F1 key when i turn it on?"
It happens because of the Bios is not configured correctly. What is BIOS?
(BIOS) Acronym for basic input/output system, the built-in software that determines what a computer can do without accessing programs from a disk. On PCs, the BIOS contains all the code required to control the keyboard, display screen, disk drives, serial communications, and a number of miscellaneous functions.
The BIOS is typically placed in a ROOM chips that comes with the computer (it is often called a ROM BIOS). This ensures that the BIOS will always be available and will not be damaged by disk failures. It also makes it possible for a computer to boot itself. Because RAM is faster than ROM, though, many computer manufacturers design systems so that the BIOS is copied from ROM to RAM each time the computer is booted. This is known as shadowing.
Many modern PCs have a flash BIOS, which means that the BIOS has been recorded on a flash memory chip, which can be updated if necessary.
The PC BIOS is fairly standardized, so all PCs are similar at this level (although there are different BIOS versions). Additional DOS functions are usually added through software modules. This means you can upgrade to a newer version of DOS without changing the BIOS.
PC BIOSes that can handle Plug-and-Play (PnP) devices are known as PnP BIOSes, or PnP-aware BIOSes. These BIOSes are always implemented with flash memory rather than ROM. Definition source : webopedia.com
Why is this happen and how to resolve this problem? There is many possible answer :
- Maybe your bios reseted accidentally : It possible to happen when the computer idle for a long of time without pluged in into the power chord. In case of this, just go to the bios set up when the computers boot by pressing the DELL button (some mainboard use the different button like F10, look at the mainboard reference) then set your bios setting to the normal state like time and date, etc. Save your setting then reset the computer.
- The bioses battery is out of use : It always happen on the old computer. Just replace the battery. Boot your computer then go the bios set up, set your bios to the normal state and save your setting. Finally boot your computer normally.
- The bios jumper is not configured correctly : Open your case to take a look at the bios jumper. Make sure there is a jumper on the bioses jumper pin and set to the correct pin.
- If the above steps doesn't resolve your problem, let's back to the bioses battery. Open your battery, you will see the battery conductor such as a pin bellow the battery, pull it up softly -softly- or you will break it then clean it up with the liquid cleaner. Put the battery back neatly then boot your computer. Go to the bioses set up and set the bios configuration to the normal state. Save your setting then reset the computer.
- If the problem remains, may your IC has broken. In case of this, go to the experts or simply replace your motherboard.
