Power-on Password
« on: November 25, 2006, 07:27:00 AM »
same thing has happened to me before.

try taking out the motherboard battery (looks like a watch battery.) leave it out over night, put it back in the morning and see if that worked.

if not you can get a linux boot disc off the net (you dont actually have to be running linux). its called password recovery or something, google it. that will sort u out.

Ok thanks for the help, I took the battery out...other places suggest five minutes, but that didn't work...so do you think I should try a day?

Thanks,

Jerek

My computer has a jumper that physically resets the CMOS and BIOS. Also, some BIOS have a master password. You might want to look into that or try contacting the manufacturer of the PC.

I'm not too familiar with that laptop, never worked on one of those before.

Now it all really depends on the type of password set, if the password is supervisor then you'll probably not remove it by removing the battery, and then theres a good chance your HDD may also very well have a lock enabled, this will be the same as the password set on the supervisor password.

If your password is set in a different setting, you may be able to remove the CMOS battery, main power battery, and PSU from the laptop and this MAY clear it, if not there is a possibility if you look around on the motherboard OR get a service manual you may find a jumper reset point that should clear this type of password.

Personally, i'd phone the manufactor and ask them for a password to get in, this will probably over-ride the set password, but you won't be able to change the current password without knowing it. The password you will be given will probably be a load of numbers and letters that mean nothing, which would be pretty much like Dell. If it happens to be like IBM, you'll have no luck and they'll tell you theres no over ride password and the best they can do is qoute you a price to swap your motherboard for a new one.

It may be the password is stored on a seperate eeprom chip on the motherboard, which is 99.9% likely going to be the case, in this instance you could get a pre-programmed eeprom chip and desolder the original and fit this one in place, which of course will clear every password in the BIOS.

Or if you'd prefer if you find out what type of eeprom the motherboard uses, you could always build a very simple eeprom reader / writer and with the appropriate software and abit of de-coding knowledge you could read the eeprom when the laptop is powered on awaiting the password and decrypt the password, in which case you can access the laptop again. If you do abit of researching into this you'll probably find what you need to learn and should be able to do it without too much trouble.

Sorry i can't be more helpfull, but hopefully this will give you abit of a guide as to what you need to take for the next step in getting logged back in.
