You can attempt to reset Bios By Pulling the CMOS battery, you will need to disassemble laptop, Not sure offhand if you have a plug in battery or one thats soldered on... Basically in a laptop there are 3 main types of Cmos battery connections.. 1 is plugged in to the motherboard using a 2 wire plug... 2 is a battery tray on the motherboard that the battery snaps into and out of... 3 is a battery that is soldered to the motherboard from both the positive and negative sides....

With any 3 of these.. You need to remove the battery... HOLD the power button (make sure your laptop battery is removed as well and unplug the AC Adapter... )
Then Reattach CMOS Battery and reassemble and attempt to power on

Note: The Soldered On Batteries Can Be Desoldered and removed...

Do Not Remove the solder from the contact points!! You need to use a pointed flat tool and your soldering gun... Use your tool to pry the battery away from its connection pad... To Do This, First Heat the soldering gun, carefully heat the 2 contact pads of the CMOS battery, as your heating them get the solder to melting point and then quickly pry the battery off the board, heat the 2 connection pads again and pull the battery away from the motherboard.... You should have the 2 contact pads still with solder left on them...

Kindly install the scanner software for printer the driver software cd just re install it will install the scanner software and make sure in device manger there is not other usb device listed if it is there just remove it. And refresh it in will automatically install the driver.

If you do not have the software, you need to download the software fromthe following location:
