The CMOS settings on most systems are buffered by a small battery that is attached to the motherboard. If it has, turn the computer off and return the jumpers or dipswitches to its original position. Once you locate and rest the jumper switches, turn the computer on and check if the password has been cleared. Please remember to unplug your PC and use a grounding strip before reaching into your PC and touching the motherboard. On laptop computers, the dipswitches are usually found under the keyboard or within a compartment at the bottom of the laptop. Some manufacturers may label the jumper / dipswitch CLEAR – CLEAR CMOS – CLR – CLRPWD – PASSWD – PASSWORD – PWD. If the documentation is unavailable, the jumpers/dipswitches can sometimes be found along the edge of the motherboard, next to the CMOS battery, or near the processor. The locations of these jumpers / dipswitches will vary depending on the motherboard manufacturer and ideally you should always refer to the motherboard or computer manufacturers documentation. Many motherboards feature a set of jumpers or dipswitches that will clear the CMOS and wipe all of the custom settings including BIOS passwords. Press both mouse buttons repeatedly during the boot Motherboard “Clear CMOS” Jumper or Dipswitch settings Most Toshiba laptops and some desktop systems will bypass the BIOS password if the left shift key is held down during boot IBM Aptiva BIOS Other BIOS Passwords by Manufacturer Manufacturer Read your manufacturers documentation for the BIOS setting before you begin typing in passwords. WARNING: Some BIOS configurations will lock you out of the system completely if you type in an incorrect password more than 3 times. These passwords are case sensitive, so you may wish to try a variety of combinations. Many BIOS manufacturers have provided backdoor passwords that can be used to access the BIOS setup in the event you have lost your password.

And finally, I added an oscilloscope to the voltage shunt and a logic analyzer to serial lines, for good measure. I also attached a ChipWhisperer with a shunt sensor board to the EC's power line. I've then attached an STM32F303RE on a Nucleo board as a general interface board to the EC's serial and reset.Įyetoy Usb Camera Namtai Driver Windows 7 32bit here.
