Removal of BIOS Password in ACER TM8471 Windows

The removal of BIOS password can be done in two ways:

Method 1:
Using eSettings management:
Step 1: Open Start Menu by clicking the Start button on your desktop.
Step 2: Go to All Programs > Empowering Technology > Acer eSettings Management.
Step 3: Click BIOS Passwords near the footer of the screen.
Step 4: With the Create Password or Remove Password options, you should be able to regain control.

Method 2:
For this method, you will have to open your computer. If you are not comfortable doing it alone, consult a technician or take the computer to a store.
Step 1: Disconnect the power cord from the desktop computer or laptop.
Step 2: Remove the cabinet cover of the desktop.
For a laptop, turn it upside-down and remove the battery. Open the hard drive compartment by sliding the cover out. Unscrew and pull out the hard drive from the laptop.
Step 3: Locate a coin-shaped clock battery (also known as CMOS Lithium battery) and remove it. Keep it aside for at least an hour.
For a laptop, disconnect the tiny power lead that connects the clock battery to the motherboard. Keep it disconnected for at least an hour.
Otherwise, you can also locate a BIOS reset jumper marked CLRP1. Move this jumper to Clear position. Let it be in this condition for at least an hour.
Step 4: After about an hour, replace the battery in the socket or move the jumper back to the Run position.
Step 5: Fit the cabinet cover and start the computer.
The computer or laptop should now boot up without asking for any BIOS password.
