Hi have you tried switching computer off then back on if this dont solve problem then you need to when you switch computer on it will say press f 1 or f 3 or similar key to enter setup screen once in the setup option you will need to change the setting for startup it will probably say a:/ then c;/ you need to change this so that your c:/ drive is first once you have done this save settings then when you switch computer on it will boot up from c:/ drive and wont ask for disk.
Or on the screen that its on try pressing esc key and see if this will let you write anything as it sounds like you are in dos mode if so type c:/ then press enter then type run this should load up then as normal if dont accept this command try type exit or win if neither work type c:/ press enter screen should say c:/ type win or windows press enter the type run again let me know how you get on ok

Laptop worked fine then shut it down turned it on again & TOSH screen appeared but then screen went black and a blue box came on saying Enter Current P'word. when i did that the laptop turned off.


Last time you used the computer you did something wrong. Of course, computer said nothing but it reared its ugly head when you restarted it! Computers are treacherous - they bite you when you least expect it - women are more predictable.

See if you can boot up by hitting the F8 key and selecting " last setup that worked" option. Do you have restore disks? If so use them to go back and possibly repair the OS. Also check with Toshiba for any other options. If nothing you just might have to reload the unit from scratch using the restore disks. If you never made them as advised then you are really scr--d. Either you buy the disks from Toshiba or you borrow some friends)S disks and do the deed.

My picture display is narrow and does not cover the screen.


Does the Genie box have screen settings in in? Sometimes hd will show in smaller screens. Makes the picture nicer. If you adjust the screen size with your remote the high definition "niceness" will not be there.

My sony vaio laptop went a black screen with a white hyphen in the upper left hand corner. It will not cut on and will not reboot


The most-likely cause is a malfunctioning (or even "dead") disk-drive.
Without the disk-drive, Windows cannot be loaded into your RAM.
So, what you get is that "lonely" underscore character.

Find a Microsoft Windows XP "installation" CD-ROM.
Insert it into your CD-drive.
Hold down the ON/OFF button until your computer turns off.
Press the ON/OFF button, to start-up your computer,
and tell your computer to boot from the CD-ROM device.
If it does boot, then the rest of your computer (excluding the disk-drive) is working fine.

Replace the disk-drive, and reinstall Windows, to "revive" your computer.

If it works fine with only the battery, then the lcd should be fine. Your power adapter might be bad.
