A black _ in the upper left hand corner (size of underscore)

Okay, does that laptop post to bios first? Example: You see the logo of the company before it goes to a black screen.
Also, do you see a blinking underscore in the top left hand corner?

On the face of the watch, there are four buttons arranged around the circle of the watch face in four positions. Starting with the upper left hand button (labelled SET), and working clockwise around the face of the watch (to ADJ., EL, and MODE), I'll label the buttons "A", "B", "C", and "D".

In other words...
Button "A" is the button labelled "SET" in the upper left hand corner of the watch.
Button "B" is the button labelled "ADJ." in the upper right hand corner of the watch.
Button "C" is the button labelled EL in the lower right hand corner of the watch.
Button "D" is the button labelled "MODE" in the lower left hand corner of the watch.
Setting the Time.
1. Press and hold D as if you were setting the alarm. As above, the stopwatch will momentarily appear and then after 2 seconds the alarm time will appear with the hour flashing.
2. Press and release D and the seconds on the time of day will begin to flash.
3. Press and release B to reset the seconds to zero provided they are below 30. If they are above 30, the seconds will reset and the minutes of the time of day will advance by one.
4. Press and release A to change from flashing seconds to flashing minutes/flashing hours/flashing day of the month/flashing month of the year/flashing day of the week. In each flashing mode, pressing and releasing B advances the value by one unit.
5. Press and release D to exit time setting mode.

I believe the "Caption Vision" is selected. By pressing the "Display" button on the remote it should toggle through the choices until "Display Off" appears. That should be all.

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.

Reboot the system
Press F8 at boot startup. In the boot menu
Choose Last Known Good Configuration. If this doesn't work

Try Safe Mode
Go to Device Manager
Roll Back any new driver you've installed
and/or
Go to Add/Remove programs
Unistall any new software you've installed

White underscores rock. They let you enter your BIOS password and stuff. Your system has achieved Zen and you're unhappy with that? You better clear up what you wish it would do for you.
