Sounds like your CMOS battery is dead, just replace it and you should be good.

    Based on the information the only other thing I can think is to check for a bad connection from you power button to the mobo.

Cant enter laptop at all


Does it start to boot Windows, or does it ask for the
password before Windows starts to boot?

There may be a password set in the BIOS, to clear that, open
the case and remove the CMOS battery.
YOU CAN DOWNLOAD PCCMOSCLEANER FROM PCCMOS.COM AND BURN THE ISO IN A CD. NOW BOOT WITH IT. IT WILL CLEAR YOUR BIOS PASSWORD

Hi saeedbjaan.
You may reset the BIOS password by removing and re-inserting the CMOS Battery.
The CMOS Battery will store the Computer date, time, BIOS password etc.,
Hence, removing and re-inserting the CMOS Battery will reset the BIOS password.
However, please let me know if you need detailed information to remove the CMOS Battery.
Hope this helps.
Please feel free to contact for further information and assistance.

Same problem but have got acer travelmate 4150


Check on motherbord again you can find cmos cell it is look like round battery cell.
Then pull it for 10 minutes so all bios settings are defaults.
Also you can clear bios with jumper find jumper on motherbord it has 3 -pin 1-2-3 right now jumper is in 1-2 position set it to 2-3 position so your bios is clear.Then again set it to it's original position.
then it not ask for password.
Let me know if you need more assistance.
Thanks.

Bios password problem


try this,

members have reported that they were able to remove their Acer BIOS passwords by simply opening their notebooks and removing the CMOS batteries for 30 minutes.
Once your BIOS password is removed, you will need to press the <F2> key during POST (Power On Self Test) to enter the Acer BIOS setup.

if that don't work, acer support charges 100.00 to reset the password, What a rip-off.
