Jeg aner ikke om det lige passer til din model, men du kan jo prøve dette:
1)Remove Laptop Battery
2)Take off Memory Cover(underneath - square cover, Sits in middle of laptop 1 retaining screw
3)Using two thumbs spread spring clips to outside and pull out RAM memory.
4)Remove clear vinyl label opposite RAM memory slots in upper left corner( laptop battery slot is on right, DVD drive is facing away from you)
5)Using a magnifying glass (unless you have perfect vision)in the upper left corner you will see JOPEN1 with a white silkscreen square next to it . Inside the square you will see what looks like the letter T over a U. Using a metal paper clip short the U to the Silver 1/4" post connecting the motherboard to the laptop case(this is your ground, it is located above what looks like a silkscreen outline of a chip)hold for 25 -30 seconds.
6) Place back your RAM memory, put in the laptop battery and test start laptop. you should see a selection of F1 or F2 for setup. Using the F2 gets you into the Bios menu where you reset the time and date. Then Tab over to the SECURITY setting tab and change your passwords. Now hit F10 key ,yes to save and your done!
Note: if your having trouble your most likely grounding the ground(that blob of solder about 1/8"dia on both ends of the "silkscreen chip outline"
