It sounds like it may be in hibernation mode. If it sounds like the PC is fully booted but just not showing a screen it may be that your window manager crashed. Try pressing to get a console window to reboot ($ sudo reboot). Otherwise try powering the system off by pressing and holding the power key or try the reset button (usually recessed i a hole) if you have one. If that doesn't work you may need to remove the power and let the battery die or remove it, to reset the machine. Be ready to reinstall Ubuntu from media. It can be while preserving your old files, if you configured your '/' and '/home' directories on separate partitions. If not you can possibly create that arrangement using the live CD before reinstalling.

Ibm thinkpad laptop

first, remove any external device as well as the ac adapter and the battery. while the ac adapter and battery is out, press and hold the power button for about 15seconds. then reconnect any power source and turn on the system. if it still doesnt turn on, remove memory, expansion cards, hard drive and optical drive then turn on the system. if it's still not turning on, the motherboard is faulty. but if it do turned on, reconnect the removed components one by one so you will determine which component is causing the issue. hope it'll help. good day. =)

Screen is blank or black

it maybe sounds a little like a problem in explorer.

try to start you computer up, press F8 within the windows loader appears. then select :start up the same way as last time it worked.

now it should work. if not then format the pc.
if you have a lot of important stuff on it you can download the ubuntu livecd and use it the get all of your stuff out of the disk.

hope that works.
