Our laptop (Toshiba Satellite L850) just started having this exact problem yesterday (not a nice New Year's present). We have Windows 7 installed also and get to the same point as RedBullPaul described (even including the reference top Minecraft only it is my son who is beckoning its return) with the mouse working but on a black screen. I have tried pressing F8 as soon as the F2 Setup and F12 Boot options appear but it appears to ignore this (I've even tried holding F8 down and frantically pressing F8 (on different occasions) so I don't miss the timing) and still go to the same blue screen "Windows Error Recovery" screen which gives me the two options of :
1. Launch Startup Repair (Recommended)
2. Start Windows Normally
The first option results in the mouse on black screen and the second option results in a loop back to the same blue screen.
I can't seem to get into F2 or F12 and as mentioned, F8 doesn't work either.
I have removed the battery and I have checked that the hard disk is in place correctly.
Our CD drive hasn't worked for a while so I was hoping to change the boot drive to USB and then try creating a USB boot "disk" (not sure how yet, but have read it can be done). The battery hasn't held a great charge for a while but I have tried removing the battery entirely and repeated the above directly from the power supply - no difference. I did notice when I was checking the power supply that there is a round lithium battery like an oversized watch battery on one of the boards....not sure if that has any significance)
Any other magic suggestions would be GREATLY appreciated !!!
