One method for protecting a computer from modifying and tinkering settingor arrangement by people who are not allowed to give a password on theBIOS ( Basic Input Output System ), or the first time the system is active and set the hardware issues ( hardware ) when the computer is turned on .
But there are times when it is very long, we've forgotten the password that we use, or we buy a laptop that BIOSnya given a password, so that when you want to reinstall windows / operating system or changing the BIOS settings, we trouble to do so.
If it happens on the computer desktop , how fairly simple and straightforward. Stay off the computer, unplug it and run one of the following ways:
Remove the CMOS battery inside the motherboard (like a watch battery with a diameter of about 2cm) beberepa minutes and back again. Or
Reset (return to the initial setting) by removing the BIOS jumper (sort of hook) specifically the motherboard. Position is usually near the CMOS battery and no information JMP1 or JP1. More details can be found in the guide / manual the motherboard. Read also my article here Computer suddenly died (Not to be lit)? try these tips
But the problem is when it happens on your laptop / notebook or netbook or computer is still under warranty. Because usually quite risky when we have to open the laptop itself, especially if there is still warranty. I could guarantee is no longer valid because the seal has been opened.
The alternative is to use the program PC CMOS Cleaner . And the good news, this program has now been released as freeware, so we can download it (download) and use it for free.Some of the benefits of using PC CMOS Cleaner include:
Displays the previous password
Clear the BIOS password (returns to its initial state). BIOS date will also be reset
Mengemballikan BIOS state to the initial state
This program can be used for windows based 32bit or 64 bit with various BIOS are supported, such as: AWARD, AMI, Compaq, Phoenix, Samsung, IBM, Compaq, DTK, Thinkpad, Sony, Toshiba and others.
Use
This program is quite easy to use, it's just that there are records of its use in order to succeed, which should be able to boot from the CD / DVD Rom . Steps:
Download ( Download ) PC CMOS Cleaner is in the form / format of ISO
Burning the ISO file to a CD-ROM, for example by using the program ImgBurn or Nero Burning ROM
Insert the CD into the CD / DVD-ROM drive, and restart the computer.
If we can access the sequence of booting the computer when the computer starts up, set it so that the first order time reading CD / DVD-ROM (set boot first from the CD)
If it made it into the PC CMOS, used to delete, reset or know the previous password.
When we can not set the order of booting the computer to be accessed is the first time the CD / DVD-ROM, then maybe the computer will not be able to boot from CD. So that the above methods can not succeed. And the only way possible is a 2 way that I described at the beginning of this paper.
If for netbooks, is usually not available CD / DVD-ROM that can be used, then the solution may be tried are looking for a CD / DVD ekstenal or attempted to make a bootable USB stick with a program such as Rufus . Once done, plug it in and then try restart the netbook, choose to boot from the media (flash) if the option is available.
