How can I reset bios password?
I want to enter my Acer travelmate 240 bios, but i forget the password.
On the newer laptops I've serviced there is no BIOS reset and pulling the CMOS battery does nothing. I've seen some with what looks similar to solder pads labeled as CMOS reset, but they won't work in most cases.
My suggestion, try the password three times, and a dialog box should pop up with a code. Punch in the code to unlock the bios here...
This has worked on every laptop that I've serviced, even new models. However, if a drive is protected at a bios level, for security, you cannot unlock the drive (this is put into place in case the drive is stolen).
ALMOST FOOLPROOF METHOD for older ACER (and other) laptops...
-USB to SATA connector (or any old USB to SATA harddisk case )
- spare SATA laptop hard disk (any size...)
Download WIN32DISKIMAGER from the web at https://sourceforge.net/projects/win32di...
or have a linux system ready with DD
Download FDlite.zip from http://www.freedos.org/download/
extract and remember where the 32MB FD12LITE.img is..
download clnpwd.zip from somewhere and extract clnpwd.exe from it
take a small SATA hard disk and write the image FD12LITE to it using WINDISKIMAGER (or Linux DD...)
copy the file clnpwd.exe to the hard disk.
put the just created hard disk and put it in your ACER (5310 etc)
wait till the HD has booted, stop the install and run clnpwd once or twice to clean system and/or user password.
When it is required, if you know your BIOS password it can be removed by following the steps below.
Removing a BIOS password:
Power on the system. As soon as the first logo screen appears, immediately press the F2 key, or the DEL key if you have a desktop, to enter the BIOS.
Use the arrow keys to navigate to Security or BIOS Security Features.
Highlight Set Supervisor Password or Change Supervisor Password and press the ENTER key.
You will be prompted to enter your current password. After you will be prompted to enter a new password, and a second time to verify it. To remove the password, leave these two fields blank and press Enter.
Press ENTER to confirm password creation.
A message will appear stating Changes have been saved. Press ENTER to continue.
Press the F10 key to save changes and restart the system.

This is the only 100% working solution:
hashes and all childish stuff described in here and everywhere do not work for Acer W510/511. Their BIOSes completely locked by Acer. There is no battery (eprom), no hashes - nothing to do as you could do usually in such case. Thats because of Acer do really intended to charge you with 100 bucks for solution of these stupid problem. But, fortunately there is existing much more better alternative, please follow these link. All you need is a flash drive formatted as FAT32 and 20 bucks. Good luck!
make short in the pins G39 and remove the cmos battery and it will be clear
the only way to unlock bios password for all laptops and worked very fine here is :
in the old laptop there is ic bios with 8 pins named almost winbon or mx ...
in the old laptops there is one ic called main you must remove it with hot air and put it in programmer
then download the bios file it must be with extension rom or bin or hex
then erase the old ic and programme it with new file
for new laptops same steps but there is another bios ic it called EC
