Reset BIOS Password Laptops

Bios password are used to secure your desktop and latop computer by preventing user from changing your bios setting or acessing to your computer while u are away.there is too type of password protection
the first one is bios setup protection:to prevent user from changing bios setting
thesecond one system proetction:to make the system unbootable intel entring the password.
but sometime user can forget their password or even wrose they can get infected by bios Backdoor verus.so sending back the unit for reset bios is expensive here is some why how to recover or remove u lost bios password
U can start first by mailing your Before hardware manufacturer support before attempting to bypass the BIOS password on a computer or laptop, then ask them if there is some bypass security.in the worest case u will not get any answer so here is the type oto follow
1) u can start by using a manufacturers backdoor password to access the BIOS
2) there is large range of password cracking software can be also used
3)on of the most efficase way is to reset the bios cmos .just look to the motherboard somewhere near your battery thir should be a jumper placed in two pin.if there is no third pin just take out the jumper then place it back .if there is a thrid jumper just place it in 2-3 possition then back to normal possition .dont forget to fully switch off your pc or laptop.u can risk of riuning your motherboard if u clear the cmos with powered up motherboard .
4)the second way how to get the bios to default value is by removing the battery .just remove it for 30 min the put it back .again u must fully unplug any power cable during the process
by Overloading the keyboard buffer.not alwais working but should help in some case
The last way is toUse a professional service
additional note:the data that remined in your hdd is not safe when u place a password for system setup .anyone how have a physic acess to your computer or laptop can easly get data stored in your hdd using another system.the only exception is to laptop from IBM there is a possiblity to lock hard drive if the supervisor password is enabled.in case where the supervisor password is reset without resetting the and hard drive password as well, you will be unable to access the data .
Backdoor passwords
Note:There is some bios That will fully lock the system when u type a wrong password
more than three time so please be carefful when entring those password and read
your bios manufacture documentation before making any change Some BIOS configurations will lock you out of the system completely if you type in an incorrect password more than 3 times. Read your manufacturers documentation for the BIOS setting before you begin typing in passwords

To bypass the bios password in some desktop and Most Toshiba laptops systems left shift key is held down during boot.just try this keyboard combinition as start and the result
IBM APTIVA BIOS
Press both mouse buttons repeatedly during the boot
Password cracking software
Here 3 of the most used software to crack or reset the system bios password.those utitility are not licenced by your motherboard manufacturer so using them will be at your own risk.there are some that can recover the password by brute forcing than display it to your screen.other software will just use assembly for award algoritme and then try to find out the cureent password.and last type by overflooding the bios
Cmos password recovery tools 3.1
RemPass
KILLCMOS

Using the Motherboard "Clear CMOS" Jumper or Dipswitch settings
many motherboard are using this jumper old one like new.just check the documentation for location and usage info.generally this jumper shuld be located near the bios chip or near the battery.there is usually 3 pin witch two of them covred with this jumper.
1) so first turn of your system
2) unplug the power cable from your psu
3) wait 30 s to be safe and to be sure that motherbard is fully decharged
4) locate the jumper
5) if there is 3 pin : the jumper show be in 1-2 possition remove it to 2-3 position wait few second than place the jumper back .
-if there in only 2 jumper : it is even easyer just remove the jumer wait few second then plae it back
6) place your psu cable back then power your system and you are done
This procedure abrove are most used with desktop computer for laptop it is even easyer the the dipswitches "used to clear the cmos" is located under the keyboard or in the botton.just check your documentation or contact your laptop manufacturer if u cant find this switches.
Removing the CMOS Battery
removing the battery is the step that u should fellow if the jumper switch that is used abrove did not help the get the password rest.
a quike overlook to the motherboard and u can easly find where u battery is placed .generaly is a sqaure battery.
lets process the step.
1) Turn of your system
2) unplug the psu cable remenber that u can burn your motherboard if the power still pluged while u are removing the battery
3) take the battery out .be carefull when removing it to not break anything.just note how the battery was placed.u need to put back later :-)
4) wait about 30 min in some case u should wait more"up to 24 hours" but generally 30 min if enough to get the bios setting rest
5) place the battery back please note how the battery was placed .placing it in wrong why can drive it to explose.
6)plug your power cable and power u your system
Note: that all previews setting will rest to default one.exemple hdd boot priority,memory setting etc... u should reconfigure them back if u had made change before.
some battery come soldered onto the mathboard then it will be harder to remove it u will need so soldeing skills.
new laptop store the password without requiring a contunious power .so rmoving the battery should not help in this case
IBM based system use special jumper to rest the bios password .again just check the documentation for additonal info
bios password recovery Win 89 tick Yes, you can crack this password if that is not set as Power on password ( the one which prompts right when you start the machine ). If you are still able to boot into Windows do this:Restart in Ms-DOS mode Type DEBUG Press Enter Type O 70 18 Press Enter Type O 71 FF Press Enter Type Q Press Enter Power the system off and on by unplugging and re-plugging the system into the power outlet
Overloading the KeyBoard Buffer
U can overload the keyboard buffer isn old system .sor exemple:hitting the " ESC " key many time rapidly. u can also try the " INSERT " + " DELETE " tick.just start rapidely pushing those two key repectively just after powering the system.and the last known keyboard tick using the "ESCAPE" "F1" it may work with the principe in some motherboard
Jumping the Solder Beads on the CMOS
An additional way consist on connecting or skeeping some specific solder beads on the chipset.be carrefull u can easly broke the motherboard if u make a wrong connection or a wrong skeep,u can check the manufacturer documentation on this or just contact them and ask.this technique is for advanced user and usually used as last try
Using a professional service
using a professional service. like Password Crackers, Inc., it offers many services for desktop and laptop computers the cost usually is between $100 and $400.
dell laptop reset bios password
u will be asked for proof to be the owner of this laptop or desktop THere was many of question regarding how to rest bios password for dell laptop but the answer can be one of those abrove solution.
Aditional type for DELL: U can give ac power & barry & then by prassing the CONTROL+ALT+E KEY THEN POWER ON THE SYSTEM & CHECK.
Last Type:To obtain the password, you have to call Dell technical support line on 800-624-9896. Provide the system ID or the Service tag. After verifying information that validates the purchase of unit, tech support would give in the master password. Type in the master password and then hold down the and keys at the same time. This would clear all the passwords.This is for Dell CP and CPI Latitudes, it has not been tried on other models. Another way to crack it is to create a short in the 24c02 chip (the markings on the top of the chip) between pins 3 and 6 when you power on! Before you try that though, remove the hard-drive and see if you get the same error.If NOT, then it is a Hard-drive password and not a system password. This fix is for a system BIOS password only. A new Hard-drive should fix it if it boots w/o the hard-drive or is cleared of a system BIOS password.The chip is below the processor so you have to solder two very small wires and bring them outside the laptop then reinstall the processor. Short the two wires and power on! Pin 1 is the one with the dot in the corner. Next pin on the same side is 2 then 3,4, and 5,6,7,8 going around the corner with pin 8 being across from pin1. The power on password will be disabled and you will be able to access the system settings via the F2 during bootup as if it was never there. This works for me, works great.Only catch isвЂÂ¦if there is also a hard-drive password, it will not disable that one and you will get the same message. But at least you will be able to put in a new hard-drive and use the laptop. I havenвЂâ„¢t figured out a fix for the hard-drive one yet, except I may try to adapt a cable to connect the laptop drive to a desktop pc and then I should be able to Fdisk it etc. (the laptop looks for the password protection, I doubt the desktop will especially another brand.) You could try to install the hard-drive in another brand laptop. Perhaps then you can Fdisk it etc. to reclaim it.For those of you who are not accustomed to soldering PC boards. Make sure the wire does not touch other pins or the case. Do NOT OVERHEAT the chip! Work in short sets of applying heat and let it rest a few minutes between attempts if you can not get it to attach right away. No more than 8 seconds at a time at low temp setting.I used some old “wire-wrap” wire. It is very-very small, single solid strand, and insulated. Be sure to ground the solder iron to the case just before you solder and REMOVE THE BATTERY FIRST!

Laptop CMOS Battery

Any laptop computer has a CMOS battery also known as RTC battery. The CMOS battery connects directly to the laptop system board and helps to retain important BIOS settings such as system time, date, BIOS configuration while the laptop is turned off or even when the main battery is removed.
The CMOS battery is rechargeable and it’s getting charged when the laptop is plugged into the mains.
CMOS batteries come in different shapes ans sizes.
On the picture below you see a basic coin cell CMOS battery. This type of batteries usually found in older laptops. This battery is removable and replaceable.
Here’s another type of CMOS battery. Basically, it’s two coin cell batteries but they are bundled together and have a cable which plugs into the system board. This battery is removable and replaceable.

On the next picture you see a CMOS battery which is soldered to the system board. In order to replace this type of battery, you’ll have to unsolder it from the system board.

CMOS BATTERY LOCATION IN A LAPTOP.
In some laptops the CMOS battery could be easily accessed from the bottom, as it shown on the picture below. As an example I took a Dell Inspiron 1720.



In some laptops the CMOS battery is hidden under the keyboard. As an example I took a HP Compaq nc6400 laptop.


Here’s the worst case scenario. The CMOS battery is hidden under the laptop cover. In order to access and replace the battery you’ll have to disassemble the whole laptop. As an example I took a Toshiba Satellite A305 laptop.


CMOS BATTERY RELATED PROBLEMS.
Here’s the most common problem related to the CMOS battery.
Each time you turn off the laptop it resets date and time back to factory defaults. When you turn the laptop back on it asks you to set date and time. If that’s the case, most likely your CMOS battery is old and has to be replaced.
By the way, removing the CMOS battery on most newer laptops will not clear the BIOS password.

Repairing Windows XP in Eight Commands

Most of us have seen it at one time or another; perhaps on our own PC, the PC of a loved one, or perhaps a PC at your place of employment. The system spends weeks or months operating in a smooth fashion, taking you to the far reaches of the wide, wibbly web, and after one particularly late evening of browsing and gaming, you shut your PC off and go to bed. Millions of people across the globe do just this every night, but a few of us have turned our PCs on the next day not to the standard Windows XP loading screen, but instead this dreaded error:

Windows could not start because the following file is missing or corrupt:

\\WINDOWS\\SYSTEM32\\CONFIG\\SYSTEM

You can attempt to repair this file by starting Windows Setup
using the original Setup CD-ROM.

Select ‘R’ at the first screen to start repair.

Which renders your PC inaccessible from the standard boot procedures of Windows XP. You try safe mode, to no avail. You’re particularly savvy and try issuing the FIXBOOT and FIXMBR commands in the Windows recovery console, but after each reboot, you’re merely greeted with the same obnoxious and terrifying blue screen of death that’s preventing you from accessing your precious data.

Perhaps you’ve also seen these error screens:

Windows NT could not start because the below file is missing or corrupt:

X:\\WINNT\\System32\\Ntoskrnl.exe
_________________

Windows NT could not start because the below file is missing or corrupt:

X:\\WINNT\\System32\\HAL.dll
_________________

NTLDR is Missing
Press any key to restart
_________________

Invalid boot.ini
Press any key to restart

Allow me to build tension by prefacing the end-all/be-all solution with my background: Having worked for the now-incorporated Geek Squad branch of Best Buy Corporation for the better part of eight months, I have seen dozens upon dozens of systems come through our department with any one of these errors, brought in by customers who are afraid they did something, have a virus, or are in jeopardy of losing their data. Prior to my discovery of an invaluable sequence of commands, our standard procedure was to hook the afflicted drive to an external enclosure, back up a customer’s data and then restore the PC with the customer’s restore discs or an identical copy of Windows with the customer’s OEM license key. If the customer wasn’t keen on the applicable charges for the data backup, we informed them of the potential risks for a Windows repair installation (Let’s face it, they don’t always work right), had them sign a waiver, and we did our best.

Neither of these procedures are cheap in the realm of commercial PC repair, nor do they inspire a tremendous level of confidence in the technician or the hopeful client.

In an effort to expedite our repair time and retain the sanity of myself and other technicians, I received permission to undertake a case study on a variety of PCs currently in service that exhibited any of the aforementioned symptoms, and I took it upon myself to find a better solution. After crawling through the MSKB, Experts Exchange, MSDN and sundry websites all extolling the virtues of a solution to these problems, I only found one that worked, and it has been reliably serving me for the better part of two weeks on seventeen PCs to date.

The process is simple: Get to the Windows Recovery Console for your particular Windows installation, navigate to the root letter of your installation (C: in most cases), issue eight commands, and reboot. The cornerstone of this process is a command called “BOOTCFG /Rebuild” which is a complete diagnostic of the operating system loaded into the recovery console; the purpose of the command is to remove/replace/repair any system files that were preventing the operating system from loading correctly. Amongst the files it fixes are:

* Windows Hardware Abstraction Layer (HAL)
* Corrupt registry hives (\\WINDOWS\\SYSTEM32\\CONFIG\\xxxxxx)
* Invalid BOOT.INI files
* A corrupt NTOSKRNL.EXE
* A missing NT Loader (NTLDR)

The command process may apply to other types of blue screens or Hive/HAL/INI/EXE/DLL-related stop errors, but I have not had the luxury of computers in this type of disrepair. The process I am about to outline is virtually harmless, and if you feel you may be able to correct your PC’s boot-time blue screens and stop errors with the sequence, feel free to try.

Let us now begin with a step-by-step instruction for correcting these issues.

Getting to the Windows Recovery Console

1. Insert your Windows XP CD into your CD and assure that your CD-ROM drive is capable of booting the CD. Configuring your computer to boot from CD is outside of the scope of this document, but if you are having trouble, consult Google for assistance.
2. Once you have booted from CD, do not select the option that states: “Press F2 to initiate the Automated System Recovery (ASR) tool.” You’re going to proceed until you see the following screen, at which point you will press the “R” key to enter the recovery console:



xp_src_welcome

* After you have selected the appropriate option from step two, you will be prompted to select a valid Windows installation (Typically number “1″). Select the installation number, (As mentioned, “1″ in most cases), and hit enter. If there is an administrator password for the administrator account, enter it and hit enter. You will be greeted with this screen, which indicates a recovery console at the ready:




xp_src_console
Proceeding With the Repair Functions

* There are eight commands you must enter in sequence to repair any of the issues I noted in the opening of this guide. I will introduce them here, and then show the results graphically in the next six steps. These commands are as follows:
o C: CD ..
o C: ATTRIB -H C:\\boot.ini
o C:ATTRIB -S C:\\boot.ini
o C:ATRIB -R C:\\boot.ini
o C: del boot.ini
o C: BOOTCFG /Rebuild
o C: CHKDSK /R /F
o C: FIXBOOT
* To “Go up a directory” in computing is to revert back to the directory above the current folder you’re operating in. If, for example, I’m in the C:WINDOWSSYSTEM32 directory, and I want to get at a file in the WINDOWS directory, I would merely type CD .. and I would be taken out of the SYSTEM32 folder and up one level to WINDOWS. We’re going to do the same thing here from the WINDOWS folder to get to the basic root of C:

xp_src_recurse



Now that we are at C: we can begin the process of repairing the operating system
and that begins with modifying the attributes of the BOOT.INI file. Briefly, BOOT.INI controls what operating systems the Windows boot process can see, how to load them, and where they’re located on your disk. We’re going to make sure the file is no longer hidden from our prying eyes, remove the flag that sets it as an undeletable system file, and remove the flag that sets it as a file we can only read, but not write to. To do this, we will issue three commands in this step:

* C:ATTRIB -H C:\\BOOT.INI
* C:ATTRIB -R C:\\BOOT.INI
* C:ATTRIB -S C:\\BOOT.INI

to remove the Hidden, System and Read Only flags.
xp_src_attributes




Now that we’ve modified the attributes for the BOOT.INI file, it’s up for deletion. The syntax for it is simple: { DEL | FILE NAME }, e.g., C:DEL BOOT.INI deletes the BOOT.INI file.
xp_src_delete



Now for the most important step of our process, the BOOTCFG /REBUILD command which searches for pre-existing installations of Windows XP and rebuilds sundry essential components of the Windows operating system, recompiles the BOOT.INI file and corrects a litany of common Windows errors. It is very important that you do one or both of the following two things: First, every Windows XP owner must use /FASTDETECT as an OS Load Option when the rebuild process is finalizing. Secondly, if you are the owner of a CPU featuring Intel’s XD or AMD’s NX buffer overflow protection, you must also use /NOEXECUTE=OPTIN as an OS Load Option. I will demonstrate both commands for the purpose of this guide, but do not set NOEXECUTE as a load option if you do not own one of these CPUs. For the “Enter Load Identifier” portion of this command, you should enter the name of the operating system you have installed. If, for example, you are using Windows XP Home, you could type “Microsoft Windows XP Home Edition” for the identifier. This gives the process some authenticity, if you’re keen on being a perfectionist.
xp_src_rebuild



This step verifies the integrity of the hard drive containing the Windows XP installation. While this step is not an essential function in our process, it’s still good to be sure that the drive is physically capable of running windows, in that it contains no bad sectors or other corruptions that might be the culprit. No screenshot necessary here! Just type CHKDSK /R /F at the C:> prompt. Let it proceed; it could take in excess of 30 minutes on slower computers, when this is finished move on to the seventh and final step.

This last step also requires no screenshot. When you are at the C:> prompt,
simply type FIXBOOT. This writes a new boot sector to the hard drive and cleans up all the loose ends we created by rebuilding the BOOT.INI file and the system files. When the Windows Recovery Console asks you if you are “Sure you want to write a new bootsector to the partition C: ?” just hit “Y,” then enter to confirm your decision.
Results and Wrap-Up

Results and Wrap-Up

It’s time to reboot your PC by typing EXIT in the Windows Recovery Console and confirming the command with a stroke of the enter key. With any luck, your PC will boot successfully into Windows XP as if your various DLL, Hive, EXE and NTLDR errors never existed. You’ve just saved yourself from many hours of work, frustration, potential data loss and shelling out your hard-earned greenbacks at a brick’n'mortar operation.

Keep in mind that this solution is only designed to resolve the issues introduced in the preface if the cause is unrelated to spyware and viruses; while I have had significant luck with rebuilding heavily-infected systems in the method I have described, it is not guaranteed. If you believe your PC has affected one of these symptoms due to spyware or viruses, today’s fastest-growing PC nuisance, please do stop by our Spyware/Virus/Trojan Forum to receive first-class assistance in quarantine, removal and repair. Be sure to read the guidelines of our SVT Forum before posting!

Good luck and happy hunting.
