    Fanya factory settings, ktk motherboard kuna button hasa kwa dell ni machine nyingine zinatumia jumper, sasa namna ya ku-clear settings ni ku-press ile button for 30 seconds while machine is off alafu una-boot machine. wakati mwingine utakuta hiyo button ipo karibu kabisa na CMOS battery

    Reset Dell BIOS Password




    Dell Dimension BIOS Password Recovery

    The BIOS password may be cleared from a Dell Dimension by moving the password jumper on the motherboard.
    The location of the password jumper on a Dell Dimension motherboard can be found by reviewing the Dimension User Guides.
    For most Dell Dimension desktops, the steps to reset a BIOS password and clear all CMOS settings are:

    • Locate the 3-pin CMOS password reset jumper on the system board.
    • Remove the jumper plug from pins 1 and 2.
    • Place the jumper plug on pins 2 and 3 and wait approximately 5 seconds.
    • Replace the jumper plug on pins 1 and 2.

    Dell Inspiron BIOS Password Recovery

    Each Dell Inspiron has a master password which will clear the BIOS password. You can get this number by calling Dell Technical Support at (800)624-9896.
    Dell Technical Support will request the Service Tag and Express Service Code from the bottom of your Inspiron.
    If you were not the original owner of the Inspiron, Dell will transfer registration of the used Inspiron from the original owner with only the Service Tag and Express Service Code from the tag on the laptop.
    To transfer the registration of a used Dell Inspiron, fill out the Transfer of Ownership form on Dell's web site.
    Dell Latitude BIOS Password Recovery

    Christophe Grenier has written a program that will calculate the master BIOS password for Dell Latitudes from the Service Tag number. That program is available here.
    If you cannot boot your Latitude to run this program, you can get the master password for your Dell by calling Dell Technical Support at (800)624-9896.
    Dell Technical Support will request the Service Tag and Express Service Code from the bottom of your Latitude.
    If you were not the original owner of the Latitude, Dell will transfer registration of the used Latitude from the original owner with only the Service Tag and Express Service Code from the tag on the laptop.
    To transfer the registration of a used Dell Latitude, fill out the Transfer of Ownership form on Dell's web site.

    Wataalam wengine wanasema kuwa ukitoa Battery inatakiwa ikae masaa 12 kabla ujairejesha, na password iliyo kwenye BIOS itaondoka.

    BIOS




    BIOS or Basic Input/Output System is the first program accessed by the processor during start up to ensure that all the other basic programs, hard drives, ports, peripherals and the central processing unit are in good working condition. BIOS is different from the computer's operating system. The operating system resides in the hard drive and provides the user interface that can be seen on the screen after start up. The BIOS program, on the other hand, can be found right in a flash memory chip or ROM located in the motherboard. It is the basic requirement for booting a computer.
    BIOS Functions

    BIOS has several functions in a computer but its most important task is to load the operating system. BIOS provides the microprocessor its first instructions upon activating the computer. The instructions of the BIOS to the microprocessor during start up are the following: power on self test which tests the operating status of all the hardware in the computer, activation of other BIOS chips in some other computer components like SCSI and graphics cards, checking and management of computer peripherals through low level routines during the start-up process, and management of clock, hard drive and other settings.
    BIOS Sequence

    The usual sequence of the BIOS program during start up begins with checking the CMOS setup for any customized settings, loading the device drivers and interrupt handlers of various computer hardware, initializing power management and registers, performing the self test for power, displaying the system settings, determining the bootable devices in the computer, and initiating the boot sequence.[​IMG]
    Changing Settings through CMOS

    To change the settings in a CMOS setup, a certain key or a certain combination of keys must be pressed during the initial start up sequence. The instructions for this can usually be found at the bottom of the first screen display during the start up process. Upon entering the CMOS set up, several options are available to the user. Setting the system date and time as well as changing the boot sequence, plug and play settings, driver configurations, memory settings, password settings, and power settings are just some of the settings that can be changed on this page.
    Updating BIOS

    BIOS, especially on older computers, can be updated from time to time. This is so the BIOS program can recognize new devices that have just been recently manufactured. To upgrade or change a computer's BIOS, a special program from the BIOS manufacturer is needed. The BIOS update used must match the original BIOS variant.
    The update is done by checking BIOS revision and date information provided on the screen during start up and comparing this with the update list in the BIOS manufacturer's website. The upgrade usually comes with a utility program but sometimes the update can be downloaded separately. This utility program and update must be copied into a floppy disk and inserted into the disk drive the next time your computer boots. This will erase the old BIOS program and install the new one.

    This is how Professional people should be given a room in Tanzania to discuss the technical matters/issues regarding our country and not politicians on Technical discussions.
