Hi! After the 5/13/15 windows update I'm stuck with a black screen and no way to follow instructions for downloads, repairs etc. on my Toshiba Satellite L675 with Windows 7. I've tried new power adapters, resetting with the battery removed, another monitor via VGA (didn't work) and the laptop didn't come with a Windows 7 disc. Randomly the laptop screen came up twice briefly; although the system was running very slow and Chrome and Firefox were hanging up, I ran a malware scan, the automated update troubleshooter, uninstalled KB3022345, restored to a previous point, backed up files to an external hard drive via Control Panel Backup (which now shows as 0 bytes) and updated several drivers. On the AMD driver, I received an error message so I downloaded and installed it from their website. After that it's stayed black; it boots but nothing's on the screen and F8 doesn't work. When the screen's black the amber indicator light I always see on the front of the laptop is not on; it may be the WiFi indicator but I'm not sure since there are two other options not lit. I'm not super tech savvy so I've literally spent a week trying to fix this and I'm exhausted. PLEASE HELP! 5/13 was my birthday..I can honestly say this is the WORST present ever!
