Hi all! I have a mid-2009 13" MBP. It had Mavericks installed on it before these problems occurred. A few days ago, I noticed that the time elapsed between pressing the power button and the appearance of the white apple logo screen were getting longer and longer (30 seconds to five minutes). If I put the computer to sleep, the only way to get out out of sleep mode would be to manually restart. The problems started getting worse after I went into the boot screen and verified/repaired the disk this afternoon. I verified the disk while the computer was running normally, and it told me that there was an issue and I should open disk utility in boot mode. I did disk utility in boot mode and the disk utility found no issues. I restarted again. Black screen. No login page. Just a single disk click/fan noise (no chime) played. I can get the white screen with no Apple logo once and a while, but it never goes beyond that. I tried inserting the Snow Leopard disk, but it looks like the keyboard isn't working so I can't even eject it or force it to boot from the disc. The white status light on the front right hand corner is a solid white. I have tried many internet troubleshooting guides for black screen to no avail. I'm currently trying to put a copy of Snow Leopard onto USB so that I can boot from that. I will try to get an external keyboard and mouse tomorrow. Does anyone know if unplugging the internal hard drive will force the computer to boot from USB?
