look for eeprom 24Cxx type (probably 24C08 or 24C16)
read it with programmer and send me that data, i can disable pass..
(dont try to fill eeprom with FF, because theres also stored display setting-you can have black display then ...
heh, pass is stored in eeprom-you cant erase with battery removing..
you can choose few ways:
1) send lappy to HP for 300bucks
2) open it and look for eeprom 24Cxx type, read it and send me that data, i modify them and send you back...
hmm, i have experience with cf28..
password stored in flash (bios is stored there), so theres not help to remove battery.. you need expensive equipment and some knowledge to remove pass from panasonic lappys..
if is it true HP then can have 24Cxx eeprom (can be readed with easy i2c prog > parts for this programmer ~5usd) but you need to open notebook..
i can remove pass from most HP eep dumps..
also can calc HP masterpassword...
