• How to Bypass BIOS Passwords

There are Back-door’s and several tricks through which it can Bypass or reset BIOS Passwords. BIOS passwords adds additional security for PC’s & laptops. Basic purpose is to prevent user to change BIOS settings & Booting without password.Before you Start you must contact customer support of hardwaremanufacturer staff and take the guidance of methods of bypassing the BIOS security. There are various methods that you can use it by yourself to bypass orreset the BIOS password That includes : 

.

• Use password cracking software like Hydra

• Using a manufacturers backdoor password to access BIOS

• Removing the CMOS battery for several minutes i.e 10min

• Reset CMOS using the jumpers.

• To get professional service 

• Overloading the keyboard buffer

Must remember that most BIOS passwords ain’t protect hard drive so if you wanna recovery first config it as a slave drive in same system or remove hard drive & then install it in identical system on How to Bypass BIOS Passwords.

• Backdoor passwords

Many BIOS manufacturers provided backdoor passwords that can accessBIOS setup. These pass are case sensitive so various combination must be tried. Keep in Mind that in US Key letter ” _ ” corresponds to ” ? ” in European keyboards. Laptop’s have better BIOS security then PC’s but we are not  concerned with it Hon ow to Bypass BIOS Passwords.

WARNING: Some BIOS configs might LOCK out your system completely if 3 times incorrect password entered.

• Password cracking software

This software is used to Crack BIOS or reset on many chipsets. If PC has BIOS admin password this won’t allow floppy Drive so these utilities will not work.Though these utilities haven’t came from manufacturers so use them at your own risk How to Bypass BIOS Passwords.

• Using the Motherboard “Clear CMOS” Jumper or Dipswitch settings

Many System’s motherboards featured a set of dip-switches & jumpers that clears CMOS and remove its custom settings including BIOS passwords. Location of jumpers / dip-switches may vary according to manufacturer so do checkdocumentation of motherboard.If documentation is not available mostly jumpers/dip-switches they are found on edge of the motherboard.while in laptops dip-switches are found under the keyboard.

jumpers/dip-switches  are often labeled as  – CLEAR CMOS – CLR – CLRPWD – CLEAR – PWD  PASSWD – PASSWORD 

NOTE: Unplug your PC and use grounding strip before touching motherboard. Once jumpers located on your PC turn on  and check if password is cleared or not, If it has then turn on and return jumpers to there original position on How to Bypass BIOS Passwords.

• Removing the CMOS Battery

On Most of the Systems CMOS settings are buffered by small battery linked to motherboard (just like small watch battery). If you power-of PC and unplug battery CMOS will reset itself and password will be blank. Before you do this you should be familiar with the manually reconfiguring the BIOS settings.

By using Capacitor Back-up power is also provided by some manufacturers to CMOS Chipsets, so if first attempt fails leave the battery out for approx 24 hours. Some Batteries are just wired on motherboard while some are soldered on it this makes the task much difficult. Experienced person must unsolder by properly placing sucker because it may damage motherboard. How to Bypass BIOS Passwords Another option is to  remove complete CMOS chip from motherboard for some time.

NOTE: Removing of battery to reset CMOS won’t work for every system. Latest laptops with stored BIOS passwords ain’t require computer power so removing the CMOS battery will not work for them.

• Overloading the KeyBoard Buffer

On Older Computers CMOS can be forced to enter in setup screen on Booting by overloading the keyboard buffer. This technique can be done by booting the system but keyboard or mouse must be  unattached. In some systems it can also be done by pressing ESC key over 100′s of times rapidly.

• Jumping the Solder Beads on the CMOS

There is also possibility to reset CMOS by connecting Jumpers on chipset. There are number of chipsets so individual jumper for every single chipset. Location of Solder Beeds may vary according to manufacturer so do check documentation ofmotherboard. How to Bypass BIOS Passwords This technique is most toughestand inexperienced users aren‘t recommended. This trick should only be used as “last ditch” effort.

• Using a professional service

If the manufacturer of PC or Laptop isn’t resetting BIOS password then there is still option of using professional service. Password Crackers. Inc provides a variety of services for laptops and PC’s ranging between $100 – $400. But for this service you have to provide proof of ownership or membership. This will not help 2nd hand PC buyers .
