How to Bypass BIOS PasswordsBIOS passwords can add an extra layer of security for desktop and laptop computers. Theyare used to either prevent a user from changing the BIOS settings or to prevent the PC frombooting without a password. Unfortunately, BIOS passwords can also be a liability if a userforgets their password, or changes the password to intentionally lock out the corporate ITdepartment. Sending the unit back to the manufacturer to have the BIOS reset can beexpensive and is usually not covered in the warranty. Never fear, all is not lost. There are afew known backdoors and other tricks of the trade that can be used to bypass or reset theBIOSDISCLAIMERThis article is intended for IT Professionals and systems administrators with experienceservicing computer hardware. It is not intended for home users, hackers, or computerthieves attempting to crack the password on a stolen PC. Please do not attempt any of theseprocedures if you are unfamiliar with computer hardware, and please use this informationresponsibly. LabMice.net is not responsible for the use or misuse of this material, includingloss of data, damage to hardware, or personal injury.Before attempting to bypass the BIOS password on a computer, please take a minute tocontact the hardware manufacturer support staff directly and ask for their recommendedmethods of bypassing the BIOS security. In the event the manufacturer cannot (or will not)help you, there are a number of methods that can be used to bypass or reset the BIOSpassword yourself. They include:Using a manufacturers backdoor password to access the BIOSUse password cracking softwareReset the CMOS using the jumpers or solder beads.Removing the CMOS battery for at least 10 minutes
6Overloading the keyboard bufferUsing a professional service:Please remember that most BIOS passwords do not protect the hard drive, so if you need torecover the data, simply remove the hard drive and install it in an identical system, orconfigure it as a slave drive in an existing system. The exception to this are laptops,especially IBM Thinkpads, which silently lock the hard drive if the supervisor password isenabled. If the supervisor password is reset without resetting the and hard drive as well, youwill be unable to access the data on the drive.Backdoor passwords:Many BIOS manufacturers have provided backdoor passwords that can be used to access theBIOS setup in the event you have lost your password. These passwords are case sensitive,so you may wish to try a variety of combinations. Keep in mind that the key associated to"_" in the US keyboard corresponds to "?" in some European keyboards. Laptops typicallyhave better BIOS security than desktop systems, and we are not aware of any backdoorpasswords that will work with name brand laptops.WARNING: Some BIOS configurations will lock you out of the system completely if you typein an incorrect password more than 3 times.

7Jetway spoomlPackard Bell bell9QDI QDISiemens SKY_FOXTMC BIGOToshiba ToshibaTOSHIBA BIOSMost Toshiba laptops and some desktop systems will bypass the BIOS password if the leftshift key is held down during bootIBM APTIVA BIOSPress both mouse buttons repeatedly during the bootPassword cracking software:The following software can be used to either crack or reset the BIOS on many chipsets. Ifyour PC is locked with a BIOS administrator password that will not allow access to the floppydrive, these utilities may not work. Also, since these utilities do not come from themanufacturer, use them cautiously and at your own risk.Cmos password recovery tools 3.1!BIOS (get the how-to article)RemPassKILLCMOSUsing the Motherboard "Clear CMOS" Jumper or Dipswitch settings:Many motherboards feature a set of jumpers or dipswitches that will clear the CMOS andwipe all of the custom settings including BIOS passwords. The locations of these jumpers /dipswitches will vary depending on the motherboard manufacturer and ideally you shouldalways refer to the motherboard or computer manufacturers documentation. If thedocumentation is unavailable, the jumpers/dipswitches can sometimes be found along theedge of the motherboard, next to the CMOS battery, or near the processor. Somemanufacturers may label the jumper / dipswitch CLEAR - CLEAR CMOS - CLR - CLRPWD -PASSWD - PASSWORD - PWD. On laptop computers, the dipswitches are usually found underthe keyboard or within a compartment at the bottom of the laptop.Please remember to unplug your PC and use a grounding strip before reaching into your PCand touching the motherboard. Once you locate and rest the jumper switches, turn thecomputer on and check if the password has been cleared. If it has, turn the computer off andreturn the jumpers or dipswitches to its original position.Removing the CMOS Battery:The CMOS settings on most systems are buffered by a small battery that is attached to themotherboard. (It looks like a small watch battery). If you unplug the PC and remove thebattery for 10-15 minutes, the CMOS may reset itself and the password should be blank.(Along with any other machine specific settings, so be sure you are familiar with manuallyreconfiguring the BIOS settings before you do this.) Some manufacturers backup the powerto the CMOS chipset by using a capacitor, so if your first attempt fails, leave the battery out(with the system unplugged) for at least 24 hours. Some batteries are actually soldered ontothe motherboard making this task more difficult. Unsoldering the battery incorrectly maydamage your motherboard and other components, so please dont attempt this if you areinexperienced. Another option may be to remove the CMOS chip from the motherboard for aperiod of time.
8Note: Removing the battery to reset the CMOS will not work for all PCs, and almost all of thenewer laptops store their BIOS passwords in a manner which does not require continuouspower, so removing the CMOS battery may not work at all. IBM Thinkpad laptops lock thehard drive as well as the BIOS when the supervisor password is set. If you reset the BIOSpassword, but cannot reset the hard drive password, you may not be able to access the driveand it will remain locked, even if you place it in a new laptop. IBM Thinkpads have specialjumper switches on the motherboard, and these should be used to reset the system.Overloading the KeyBoard Buffer:On some older computer systems, you can force the CMOS to enter its setup screen on bootby overloading the keyboard buffer. This can be done by booting with the keyboard or mouseunattached to the systems, or on some systems by hitting the ESC key over 100 times inrapid succession.Jumping the Solder Beads on the CMOS:It is also possible to reset the CMOS by connecting or "jumping" specific solder beads on thechipset. There are too many chipsets to do a breakdown of which points to jump onindividual chipsets, and the location of these solder beads can vary by manufacturer, soplease check your computer and motherboard documentation for details. This technique isnot recommended for the inexperienced and should be only be used as a "last ditch" effort.Using a professional service:If the manufacturer of the laptop or desktop PC cant or wont reset the BIOS password, youstill have the option of using a professional service. Password Crackers, Inc., offers a varietyof services for desktop and laptop computers for between $100 and $400. For most of theseservices, youll need to provide some type of legitimate proof of ownership. This may bedifficult if youve acquired the computer second hand or from an online auction. How to make a computer faster: 6 ways to speed up your PCBy following a few simple guidelines, you can maintain your computer, help increase your PCspeed, and help keep it running smoothly. This article discusses how to use the toolsavailable in Windows 7, Windows Vista, and Windows XP Service Pack 3 to help make yourcomputer faster, maintain your computer efficiently, and help safeguard your privacy whenyoure online.Note: Some of the tools mentioned in this article require you to be logged on as anadministrator. If you arent logged on as an administrator, you can only change settings thatapply to your user account.1. Remove spyware, and help protect your computer from viruses:Spyware collects personal information without letting you know and without asking forpermission. From the websites you visit to user names and passwords, spyware can put youand your confidential information at risk. In addition to privacy concerns, spyware canhamper your computers performance. To combat spyware, you might want to consider usingthe PC safety scan from Windows Live OneCare. This scan is a free service that helps checkfor and remove viruses.Download Microsoft Security Essentials for free to help guard your system in the future fromviruses, spyware, adware, and other malicious software (also known as malware). MicrosoftSecurity Essentials acts as a spyware removal tool and includes automatic updates to helpkeep your system protected from emerging threats.The Microsoft Windows Malicious Software Removal Tool is another utility that checkscomputers running Windows 7, Windows Vista, Windows XP, Windows 2000, and WindowsServer 2003 for infections by specific, prevalent malicious software, including Blaster,Sasser, and Mydoom, and helps remove any infection found.
92. Free up disk space:The Disk Cleanup tool helps you to free up space on your hard disk to improve theperformance of your computer. The tool identifies files that you can safely delete and thenenables you to choose whether you want to delete some or all of the identified files.Use Disk Cleanup to: Remove temporary Internet files. Delete downloaded program files, such as Microsoft ActiveX controls and Java applets. Empty the Recycle Bin. Remove Windows temporary files, such as error reports. Delete optional Windows components that you dont use. Delete installed programs that you no longer use. Remove unused restore points and shadow copies from System Restore.Tip: Typically, temporary Internet files take the most amount of space because the browsercaches each page you visit for faster access later.3. Speed up access to data:Disk fragmentation slows the overall performance of your system. When files arefragmented, the computer must search the hard disk as a file is opened (to piece it backtogether). The response time can be significantly longer.Disk Defragmenter (sometimes shortened to Defrag by users) is a Windows utility thatconsolidates fragmented files and folders on your computers hard disk so that each occupiesa single space on the disk. With your files stored neatly end to end, without fragmentation,reading and writing to the disk speeds up.When to run Disk Defragmenter:In addition to running Disk Defragmenter at regular intervals (weekly is optimal), there areother times you should run it, too, such as when: You add a large number of files. Your free disk space totals 15 percent or less. You install new programs or a new version of the Windows operating system.Running Disk Cleanup and Disk Defragmenter on a regular basis is a proven way to helpkeep your computer running quickly and efficiently. If youd like to learn how to schedulethese tools and others to run automatically, please read Speed up your PC: Automate yourcomputer maintenance schedule.4. Detect and repair disk errors:In addition to running Disk Cleanup and Disk Defragmenter to optimize the performance ofyour computer, you can check the integrity of the files stored on your hard disk by runningthe Error Checking utility.As you use your hard drive, it can develop bad sectors. Bad sectors slow down hard diskperformance and sometimes make data writing (such as file saving) difficult or evenimpossible. The Error Checking utility scans the hard drive for bad sectors and scans for filesystem errors to see whether certain files or folders are misplaced.If you use your computer daily, you should run this utility once a week to help prevent dataloss.5.
