HP Pavillion dv2000
Windows XP HE
Phoenix Bios 4 release 6

Friends son set a bios password on this laptop and cannot remember what it is! (Now grounded till fixed!)

Have tried the 'backdoor' passwords for Phoenix Bios without success. Also entering password, blank etc.

Have also tried removing Main battery, CMOS battery and leaving for 24 hours, 48 hours, hours and hours etc restarting just on mains power with and without CMOS battery in place.

Have tried removing and reinserting Ram, HDD etc all withut success

Everytime PC boots up display momentery post screen then blue box saying Enter Password.

Have had a poke around for some sort of bios jumper but cannot find one.

Other than hitting with large hammer any suggestions.

HP service centre want over 250GBP to fix.

As always any and all assistance gratefully received.
