    that unfortunately is the problem, you can not clear it or change it without the current one, unless you wipe it out. Do not have existing password

The security password is set in the system BIOS. You must boot to the setup of the laptop and change it there to be nothing. You must know the password to set it to nothing.

How to remove bios password in laptop dell model no pp19s


BIOS passwordsare used to add some extra security to computers. You can either set a passwordto prevent access to BIOS settings or to prevent PC from booting. But sometimesthis extra security might become a pain when you forget the BIOS password orsomeone changes your system BIOS password intentionally. But there is noneed to worry. There are many known ways to reset / remove / bypass thepassword: · By removing CMOS battery · By using motherboard jumper · By using MS DOS command · By using software · By using Backdoor BIOS password Now I'll try to explain each methodone by one: By Removing CMOS Battery:
Almost allmotherboards use a small coin d CMOS battery to store all BIOS settingsalong with the password. To reset the password, unplug the PC, open the cabinetand remove the CMOS battery for approx. 15-30 minutes and thenput it back. It'll reset all BIOS settings as well as the password and you'llneed to re-enter all settings. If it fails,then try to remove the battery for at least one hour. By Using MotherboardJumper: Almost allmotherboards contain a jumper that can clear all CMOS settings along with theBIOS password. The location of this jumper varies depending upon themotherboard brand. You should read your motherboard manual to check itslocation. If you don't have the manual then look for the jumpers near the CMOSbattery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS,etc. When you findthe jumper, look carefully. There will be 3 pins and the jumper will be joiningthe center pin to either left or right pin. What you need to do, is remove thejumper and join the center pin to the opposite pin. e.g. if the jumper joinscenter pin to left pin, then remove it and join center pin to right pin. Nowwait for a few seconds and then again remove the jumper and join the center pinto left pin. Make sure toturn the PC off before opening the cabinet and resetting the jumper. By UsingMS DOS Command: This methodworks only if you have access to the system when its turned on because thismethod requires MS DOS. Open Command Prompt from Programs menuand provide following commands one bye one: Debug o 70 2E o 71 FF quit NOTE:The first character in the above commands is English alphabet "o"and not the number 0. After providing the above commands, restart your systemand it should reset the CMOS Settings along with the BIOS password. If you arecurious to know how it works? then let me explain the above commands: In this method we are using theDebug tool of MS DOS. The "o" character present atfirst in these commands, outputs the values to IO ports. The number 70and 71 are port numbers which are used to access CMOS memory.By providing FF value we are telling CMOS that there is aninvalid checksum and it resets the CMOS settings as well as BIOS password. By UsingSoftware: There are a few software which canalso reset CMOS settings or BIOS password or both within a few clicks. But asstated above you should have access to a system which is turned on and shouldhave access to MS DOS or MS Windows: CmosPwd By Using Backdoor BIOSPassword: Some BIOSmanufacturer put a backdoor password in BIOS which always works irrespective ofwhat password you have set in BIOS. Its a master password which is used fortesting and troubleshooting purposes. AMI BIOS Passwords: A.M.I.

ACER ASPIRE 4730Z. How do I clear the CMOS (password)?


Below is the steps for clearing the password. Below that is the link for the manual, the picture of the jumper tabs is on pg. 153, good luck

Steps for Clearing BIOS Password Check

If users set BIOS Password (Supervisor Password and/or User Password) for a security reason, BIOS will ask
the password during systems POST or when systems enter to BIOS Setup menu. However, once it is
necessary to bypass the password check, users need to short the HW Gap to clear the password by the
following steps:
• Power Off a system, and remove HDD, AC and Battery from the machine.
• Open the back cover of the machine, and find out the HW Gap on M/B as picture.
• Use an electric conductivity tool to short the two points of the HW Gap.
• Plug in AC, keep the short condition on the HW Gap, and press Power Button to power on the
system till BIOS POST finish. Then remove the tool from the HW Gap.
• Restart system. Press F2 key to enter BIOS Setup menu.
• If there is no Password request, BIOS Password is cleared. Otherwise, please follow the steps and
try again.
NOTE: The steps are only for clearing BIOS Password (Supervisor Password and User Password).

Please help me reset my bios password on acer travelmate 2410


First you need to remove the laptop battery at the back side. Find some screw there and remove it locate the CMOS battery and jamper.

The BIOS password is stored in CMOS memory that is maintained while the PC is powered off by a small battery, which is attached to the motherboard. If you remove this battery, all CMOS information (including the BIOS password) will be lost. You will need to re-enter the correct CMOS setup information to use the machine. The machines owner or user will most likely be alarmed when it is discovered that the BIOS password has been deleted.

On some motherboards, the battery is soldered to the motherboard, making it difficult to remove. If this is the case, you have another alternative. Somewhere on the motherboard you should find a jumper that will clear the BIOS password. If you have the motherboard documentation, you will know where that jumper is.

If not, the jumper may be labeled on the motherboard. If you are not fortunate enough for either of these to be the case, you may be able to guess which jumper is the correct jumper. This jumper is usually standing alone near the battery. If you cannot locate this jumper, you might short both of the points where the battery connects to the motherboard.

How to reset BIOS password on VGN FE880E End-user has locked the BIOS, and needs to reset it. It there a jumper like on most desktop PC's? Suggestions are appreciated. Thank You.


If you have forgotten your BIOS or system password, there are no software tricks or magical gimmicks that will get the password cleared. Laptops are different in that they are designed to not work with “backdoors” etc. for security reasons. There is one true way that works most of the time and that is hardware.
The Cmos (RTC) battery that is mounted on the motherboard in most cases holds the key, if your motherboard has the battery that is connected to the motherboard by using a two wire socket that plugs into the MOBO, then here is the procedure.
On the motherboard where the battery plugs into, you will see two pins sticking straight up, these engage the plug on the battery side. These two pins have to be “shorted” and then the motherboard powered up for approx. 30 seconds, then power down the system and replace the Cmos battery and reboot. Your password problem should be cleared up. The best way to “short” the pins is get another cmos battery and cut the wires from the battery part, bare the ends and twist together, this will short the pins. Make sure you tape the connection good on the jumper you just made….don’t want to touch anything else with powered up bare wires. Good luck.

If you've forgotten the BIOS password you need to short the CMOS by setting the jumpers or remove the battery.

Assuming you can get to the CMOS button cell battery, remove all power, pull the button cell out for about a minute, then put it back. The next boot-up should load right to setup, or to an error screen telling that CMOS is corrupt and to run setup.
