I know my Laptop BIOS works because on switching on I get the “Toshiba Leading Innovatio»»” flyer displayed on my laptop screen. I have a separate monitor, as an extended destop, connected, and it should be noted this shows nothing. Then the screen goes blank and after about two mintutes the flyer pops up again for about 2 secs and the screen blanks again. There is a backlight (I can increase the screen brightness with Fn F3) but the screen displayes nothing. The machine will sit there doing nothing. After abot 5 mins I get a ping sound, like when a USB device has been inserted, even though none has been. If I insert a USB device I get the ping sound ackowledging that a device has been connected. I have tried the “holding the off switch for 60 seconds and restart” and the “shift F8 switch off” techniques, but none worked. I have left it running overnight, and nothing worked. Can any one offer advice.
It’s possible that an update has gone on and stopped Windows from working correctly. The first thing I would try is a system restore to before the updates went on, if any. One thing I just thought of which should be done before the above because it’s the easiest and quickest is a hard restart. Turn the laptop off, remove the battery and hold the power button down to power cycle the laptop. Then put the battery back in, and try turning on again as normal.
