    xp.. I'll give that a try thanks for your help.......nick

    Thanks for your reply..............followed your advice re. removing battery...problem still persists. Not sure where to flash bios.

    I am only assuming that clearing the bios will cure my problem,

    as the pc has been infected with a virus


  • a_mussell Feb 20, 2009

    well guys thanks for all your help it would seem that it may have been a application problem.............i reformatted the drive and re-unstalled windows (overkill perhapes), but it has cleared the fault.

    thanks again

    This can be tricky. Which OS are you using? XP, Vista, OS X?

What may be easy to you and me darkchild IS usually tricky for the average end user. Just pulling out the battery doesn't always remove the bios password. Most laptops nowadays store the bios password on a chip and pulling the battery won't clear those types of stored passwords or HD passwords either, so keep this in mind.

I read on a forum that most Medion laptops use this bios password:


Give it a shot.

    So it was a Windows password and not a bios password, right?

    I'm glad you sorted it out either way. Best of Luck! Oh and I would recommend you downloading a copy of AVG Free to avoid viruses in the future!

Clearing bois password

Acer laptops are equipped with a BIOS utility.
The BIOS (which stands for "Basic Input Output System") acts as an interface between the hardware and software installed on the computer.
On some computers, a BIOS password may be required in order to boot the computer and make changes to the BIOS settings.
If you are unable to access the BIOS settings and do not know how to reset the BIOS password, you might be tempted to send the computer back to the manufacturer for repair.
Fortunately, that's not necessary as there is a simple way to do this on your own.

Go to "Start," then perform a search for "Command Prompt."
The Windows Start button is located in the lower-left corner of your computer screen.
Double-click on "Command Prompt" to open the application.
You will need to use MS-DOS commands to reset the BIOS password.
Type the following commands one by one in the order shown:
o 70 2E
o 71 FF
Make sure that you are typing the letter "o" and not a zero at the beginning of the second and third commands.
Reboot your computer by clicking "Start," "Shutdown," and then "Restart."
The BIOS password will now be reset to default.
you could download all of these or just one save them to a usb drive for later use if one fails to remove the password
At some stage you might need to press Ctrl+Enter rather than just Enter if on a Dell Latitude E5410
A CMOS BIOS password recovery tool
Editors note: This tool should only be used by experienced computer users.
Please see the enclosed read me if you would like to run it from Windows.
Failure to follow instructions (from Windows) will cause your anti-virus to flag this as a virus.

Emachines e525 bios password

After hours of searching I finally found a fix:
1. Remove the battery
2. Remove the HDD
3. Removed the RAM to make the solder points, marker 'J1' on the motherboard visible
emachines-e525-bios-password-bueb2fgw15ei4wj3vksvhmc2-2-1.png 4. I then used a paper clip and sticky tape to join these solder points
5. With the solder points joined, insert one stick of RAM and turn the machine on
6. Wait until the laptop is in a post BIOS state (past the screen where you can press F2 for setup and where the logo shows) and remove the paper clip. This has to be removed while the laptop is still on.
7. Turn off computer, press F2 to enter BIOS and you should find there is no password.
Repeat the above steps if you find this doesn't work.

Laptop is asking for a boot password

You need to clear your CMOS settings, where the password is stored. It is volatile memory, but there is a small hidden battery that keeps the memory stored. You need to temporary remove it.Remove the small plastic cover on the bottom where your RAM/Hard drive reside. It should be a single screw. There will be a small 3v Lithium Ion coin battery in there. Remove that battery, remove your laptop battery, and unplug your power adapter. Leave it all unplugged fora couple minutes, put it back together, and your password will be gone.

Medion Akoya mini 10 netbook 1210 asks for password to enter bios. I want to reset but never known the present password

The most common way that most of us know on how to reset or clear the BIOS password is to physically remove the power from the computer by disconnecting the power plug and then removing a battery for 30 minutes from the motherboard. Another way is to reset the clear CMOS jumper on the motherboard itself. Both of the 2 methods mentioned works because most motherboards use a battery to sustain the BIOS/CMOS settings for the motherboards PROM chip. So by cutting off the battery power, the BIOS/CMOS settings will be erased or

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.
