ive been given this laptop to work on as my friends just gotten 6 in to sell on and i need to remove the power on password that no one seems to know... :confused: i called HP and they said they cant (or wont) help me unless i send them the laptop and pay them to do it! but they did tell me where the CMOS battery was as i couldnt find the bugger.

so today i had to strip this laptop down to get to the CMOS battery, and when i say strip, i mean i had to take EVERTHING apart. took 2 hours :( basically HP have put the bat on the underside of the motherboard with no access panel for it on the bottom :confused: idiots...

nevertheless, the bat was removed for around half an hour, ive put it all back together and booted it and besides the small fire (more on that in a moment) the passwords still there and joyfully intact.

The Fire: ( YEY!!! FLAMES!!!)
when i booted it for the first time, there was a small fizz then something glowed white hot, small flame :eek: then white smoke !!! :eek: looked like ive fried the external VGA connector somehow, but the laptops still working so no massive harm done...
 
you could try taking the main battery out and leaving it for a while (could be a long time :( ) until the CMOS battery discharges

edit: it may have been a good idea to leave the CMOS battery out for a bit longer than a half hour after all that work (just to make sure)

all the batterys were taken out for over 40 minutes, everything was disconnected from each other, the laptop was nothing more than seperat parts laid out across a desk.It seems the passwords written on a 64kb static memory chip so its never going to lose the information (something the guy at HP did warn me about but he wasnt sure if it was on this model)

EDIT: a CMOS will discharge relatively quickly, most discharge within seconds, thinking about the 2 episodes of frasier i watched, i was gone for nearly an hour.

thinking back i remember a mate with an IBM laptop with its hard drive locked with a password

you should have seen my face as he threw the 60gb 5400rpm drive in the bin (5 metres away) :eek: then proceeded to tell me that the drive was useless without the password (totally secure unchangable)

could try flashing the bios?
usually a cmos reset does the trick on a desktop dunno if there is a jumper for this on lappys

no way to flash it :( and nope, no CMOS clear jumpers on this laptop.

yup hardware with lost passwords are pretty much scrap metal :(
 
Toshiba, dunno about HP, say that you can remove the password by removing the battery + residual power, and leaving the laptop for 24 hours.
 
i know there are tools about to recover / reset cmos passwords, try google i dont know any places that do them off hand but probably not the sort of sites you can mention here anyway

im not stripping this ****** again... lol. the guy at HP said 2 minutes to discharge, an hour would have been more than enough. he just didnt have the details about the type of memory that the laptop info is stored on.
 
ah, you mean the standard battery pack, the reason they say 24 hours is because without the mains power or the battery pack, the CMOS battery is unable to recharge and will discharge within 24 hours, my point is that i actually had the CMOS battery and the laptop battery out for nearly an hour and it didnt solve it, which means that the passwords written on a static memory chip and regardless of charge, its not going to lose the information. :(

Not True!

I have unlocked many IBM laptops with forgotten passwords!
O.K it does require that you strip it apart and solder a few cables to certain legs on the ATMEL 24RF08 PIC and then reading it with a very basic and easy to build serial PIC reader connected to another PC/Lappy.
You then also need to decrypt the HEX as it's encrypted but that’s very easy as some clever dude made a simple program for that.

So no it's not impossible just need to do some research and have a very steady soldering hand.
