Alright, here is the solution!! I read this on another thread here and was so upset with my Toshiba's black screen (I am a flight attendant and drag this laptop all over the world and back...I thought I broke it while going through security..where, of course they handle everything with tender loving care..lol)
Well I was just about to go online to buy a new laptop because my screen was black when I read a thread on this site and whoever figured this out WAS a genius...
This is what this person said to do.....
1) UNPLUG THE LAPTOP
2) REMOVE THE BATTERY
3) HOLD DOWN THE POWER BUTTON FOR ABOUT 30 SECONDS TO 2 MINUTES
4) THEN PUT THE BATTERY BACK IN
5) START IT UP..
It worked immediately...I nearly cried when it started up...We are in a recession right now and the last thing I needed was a laptop repair bill..
Kudos to the person who shared this on this website...I lost the 'thread' but wanted to share it with everyone!
