need to get past bio passcode
ive tried to use external harddrive . no good.so what must i do?
Try this :
Turn off and unplug the laptop from power
Remove the battery
Open the smallest door on the bottom of the computer with a #1 Phillips screw driver
Look for two small metal contacts labeled RTC(RST). Using a flat head screw driver, touch both contacts at the same time for 30 seconds.
Re-install the battery
Plug in your computer
