How can I reset bios password?
I want to enter my Acer travelmate 240 bios, but i forget the password.
Acer entered the world of laptop computers in 1997 when it purchased Texas Instruments' mobile PC division.
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.

I find an article about how to reset BIOS password on Windows, perhaps you can have a reading and I think it will help you sovle your problem and if you have any other questions you can also comment as below and the writer will help you. Read it in:
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!

I have an Acer Travelmate 8571 laptop and forgot my BIOS Password, so laptop is not starting up.
I removed the CMOS Battery for 30 minutes, but no joy :(
So when i press F2 during startup, its still asking for a Password...
When i dont press F2 during startup , it then gives error reading boot configuration (\Boot\BCD).
When i put a windows install CD , it wont startup with install CD, but its trying to read the info from the hardisk where most probably the boot section is faulty.
So i cant go into BIOS to change the setting to boot from CD, because i dont have the BIOS password.
So i am totally stuck.
Please advise what to do.
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.
search on youtube for clnpwd.
