View Full Version : Bypassing Power on Password

05-11-2004, 02:37 PM
I have a friends laptop he has given me for repair
I have sourced a new power supply & it arrived today
Now that I have power & the machine boots I discover it has a boot password on it
It stops me accessing the floppy so I can't run any BIOS pwd crackers or CMOS Kill etc
It's an Acer Travelmate 512DX
I've googled to death & come up with nothing.
I've had it to bits & the battery out for over an hour, with no luck
I can't find any jumpers on the board for clearing the BIOS
I don't know what BIOS it has so can't try any of the default/Factory ones I've found so far
I believe Acer used to have their own BIOS's made up?
I'm buggered!!!

Any ideas or does anyone have a list of Factory passwords I could try?
The lappy belonged to my friends 14yr old son who died a couple of years ago, so finding out what the password is isn't an option.

The links on the first page of links from "acer bios password" to Google might help. CmosPwd is a programme; there's also a list of manufacturer backdoor passwords. (Acer is said to be phoenix/ibm).

Thanks Graham, already been there but can't get access to floppy without the password so can't run the program
Will continue to try passwords, could be a long haul methinks

Thanks Rob99, already been there as well with no luck
leaving the battery out for 24hrs this time as I read some manufacturers back the password up to a capacitor as well in case the battery needs replacing.

If that works, remember to explicitly save the the BIOS settings with the password disabled. The memory locations aren't properly erased by the power off. They only have "proper" settings when they have been written.

I've put the battery back in for another try & the BIOS password has been disabled but now it wants a hard disk password DAMN!!
I read somewhere they can have 2 levels of protection so back to google again.
I can access the BIOS now but can't change the HDD password in the BIOS without the old one

That sounds a bit awkward. ;-) It might be that you can't remove the disk password unless there is an "administrator" (BIOS) password. Try setting a new one.

Thanks Graham, I've set a new 'Setup pwd' & a new 'Power on Password' saved & rebooted
Both passwords work but still won't allow me to change the 'Hard Disk Password' or access floppy or CDROM to hack it
Oh Boy!

This from a UK Company that specialises in password removal on lappys @ approx $300 a shot

"Supervisor & User password removal does not include Hard Disk password removal; Hard Disk password removal can be done, but is not normally economical"

Looks like I'm going to be s*** out of luck

What happens if you remove the hard disk?

ive found "format c" to be particulary useful in situations such as yours

You "rebooted" after setting the passwords. Try POWER OFF and restart. :D A real cold start might help. Might not, of course. :D

>ive found "format c"
That'd be great if I had access to Floppy, or CDROM but I don't till I have a password.

I might have to buy another drive as suggested somewhere I read.
But surely that won't work as the Hard Drive password is set in the BIOS & wouldn't matter what drive I had in it

Do you reckon hooking it up to another machine as slave & formatting will remove the password

Contact Acer support on 0800 223769 (have your serial number handy) hopefully they can assist.

Thanks Mzee, already done that & someone was going to get back to me
Still waiting....
But in the meantime SUCCESS!!
One of the family members remembered helping him type in a pwd on one of his bad days & voila I'm in.
Thanks to all.

Well, the password protection works. :D
