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).
try restarting the computer in safe mode or try login bios menu using F2 and reset the bios if you have any other issue in computer that can be fixed doing the normal reset . try this post how to reset the computer password and settings see if that works for you .
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.

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!
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

i solved via the clnpwd tool :)
i put the clnpwd program on external usb disk, then removed my internal laptop harddisk, booted my laptop from usbdisk, runned the clnpwd program and i removed all bios password.
clnpwd is the only solution that worked for me.
