Have you tried downloading from http://www.samsung.com/us/support/owners/product/NP-R730-JB02US ?

on my keyboard I hold down the FN button and either the up or down arrow key depending on whether you want it brighter or lower

Can you power it up with out the battery? Just the power cord, no battery? You very well may have fired it sadly. I think Best Buy Geek Squad may check it out for you free of charge, but I can not be certain of that.

Hello, Go to Download Center Download Software Firmware Drivers Manuals Samsung. enter your laptops model number, make, etc. the website should step you through the process.

The most likely cause is that you have picked up a virus in an email and unless you have a clean backup of contents all is likely lost without expensive intervention at very high tech level within Microsoft and even then it may not work. Can you boot to safe mode? If so, try to run spyware to seach the disk. I'm not optimisitic that you'll be able to boot to safe mode even. Do you have the rescue disk that came with the system? Try rebuilding the system, although you may well perpetuate the virus regardless of using the factory rebuild disk because it is extremely difficult to delete even with multiple reformats.

try to run some good antivirus..... and also some free windows diagnostic softwares... some viruses, or malware preventing comp from restarting

Need to know your operating system.
