Ok so I'm trying to boot up my Toshiba Satelitte c655 and it freezes to a black screen w/ a still ( _ ) in the upper left hand side. My hard drive is removed due to it not working and I was booting Linux Mint 12 via thumb drive. I cant even get into my (h2o insyde) BOIS due to password lock and tried removing the battery under keyboard and also shorting out the B500 solder pionts. Any suggestions??
