How do I reset the BIOS password of an Advent 4211 netbook?
I'm hoping for a software solution to remove the password or find out what it is or even change it.
It's my laptop but I can't remember what I set the BIOS password too. I know on a PC to take out the battery and clear it with the jumpers but on a laptop I'm slightly scared of breaking something.

Usually there's a dip-switch underneath the keyboard.
This it what it looks like on an Acer laptop:
One of the settings will be to clear the BIOS password. It may be labelled as such. Simply flick the white switch to toggle it on and off. (Refer to your manual for further details)

I did take the back off the laptop and could get at the battery, HDD etc but didnt see any switches, is it always under the keyboard? I'll try and take it to pieces again, thanks for your help – Andrew – 2010-02-08T10:30:57.427
I've only done this on Acer laptops, and (despite searching) I couldn't find any images for your model. It's literally under the keyboard; you shouldn't need to take the back of the laptop off. Should be a way to remove front faschia then lift up keyboard. – RJFalconer – 2010-02-08T13:39:02.627
managed to retrieve the old password in the end but i did find a couple of software tools for editing bios info which looked pretty interesting I'll post links later – Andrew – 2010-02-08T14:11:03.087
On my asus laptop, it's two little pads under the hdd. you have to short them with something metal. – Fake Name – 2010-04-23T04:29:06.200
its in no-way really needed a BIOS password; don't do it if you don't need it. I wonder why you did that in the first place. Do you have multiple users or so? what i know from PC's is that you'll need to push some kind of thing on the motherboard to reset the BIOS, but i don't know what's the safest way on a notebook. – Deniz Zoeteman – 2010-02-07T12:26:02.703
4@TutorialPoint - I beg to differ, the fact that I set a BIOS password got me back a stolen laptop once, eejits walked into a computer shop and wanted the password removed, clerk contacted the police with make and model and the rest is history :) – None – 2010-02-07T13:08:25.150
@Molly: Could it be that the OP has a stolen laptop and wants the password removed? Curious. When I want to protect my laptop, I use whole-disk encryption rather than BIOS. You can't circumvent encryption by pulling a battery out. – OwenP – 2010-02-07T15:51:00.037
@OwenP - no, i'm not saying that. but i'm rather wary to give advice on how reset a BIOS password with a laptop, and i certainly wouldn't do that for someone unbeknown to me without proof of ownership. hence my answer would be: contact Acer technical suppoort. and as for disconnecting the CMOS battery, this doesn't work for modern laptops. – None – 2010-02-07T17:22:54.353
@Molly, although I agree with the sentiment, I think security through obscurity is bad thing. My answer is pretty vague; so perhaps I can get away without feeling too guilty :P – RJFalconer – 2010-02-07T19:38:36.940
I have a receipt for my laptop thank you very much. – Andrew – 2010-02-08T10:28:44.060
I've bought industrial-surplus laptops from e-bay with bios passwords on them.
There are a whole host of reasons one could want this info that aren't malevolent. – Fake Name – 2010-04-23T04:25:41.793
@Molly Pulling the CMOS battery absolutely clears the BIOS password on modern laptops. Thats what the battery is there for, without it the CMOS will lose its setting over time. I dont know if this holds true fro EFI/UEFI though. – Keltari – 2011-09-13T03:51:19.100
