NEED TO FIND THE BIOS BUTTON BATTERY AND FUSE FOR SCREEN
Most laptops do not have a BIOS button to reset the BIOS settings.
To reset the BIOS just remove the BIOS battery and wait for approx.20 mins for the battery charge to discharge then replace the battery.
OR
After removing the BIOS battery just short out the battery terminals on the motherboard with a paper clip, the replace the BIOS battery and go into the BIOS setting to change the Date and Time etc.
There isnt a fuse for the LCD screen.
If your laptop appears to boot up and the hard disk LEDflashes, then the problem is probably a back light fault. This can be a faultyinverter or a faulty CCFL lamp.
