Try connecting an external monitor to your laptop to see if the symptoms go away.

Laptop no video (or video problems), and battery, AC adapter, power jack T shooting.

See response 1:
http://www.computing.net/answers/ha...

DO NOT plug in or unplug a monitor's video cable into / from a video port while the computer is running. Doing so can damage the monitor's circuits and/or the video adapter's circuits.

Some laptops will display on an external monitor without you having to do anything.

If you get no video on an external monitor, some laptops have a key combo that you must press to toggle the display to external video only / built in display video only / sometimes both - see the Owner's or User's manual for the model.

Your response 2 info is not clear.

Are you getting the same thing happening on the external monitor's display, or no display on the external monitor?

If the latter, see the last part of response 1. Sometimes you need to press a key combo.

Do you have an external hard drive plugged in ?
If so, try unplugging that then attempting to boot.
(I know from experience that Vista can fail to load all the way when an external drive is plugged in for reasons that are NOT clear to me.)

If that doesn't apply or if it does but that doesn't help....

What went on the last time you used the computer when it still worked fine before you shut down the computer?

Did you load software, or did Windows Auto Update load updates while shutting down, or did some program auto load updates or load updates with your consent ?

Try booting into Safe mode, or Safe mode with networking, or loading Last known good configuration.

Remove any bootable CDs or DVDs in drives.
Press F8 repeatedly while booting, do not hold down the key, starting early in the boot sequence.
When the boot choices menu appears, choose
Safe mode, or Safe mode with networking, or load Last known good configuration.

If that works, click on the Vista logo button (Start) bottom left of the desktop screen, in the Start Search box, type: cmd , click on OK,
then type: CHKDSK /F C: ,press Enter
Answer Yes to any question. You will probably be told CHKDSK will run the next time you boot the computer. Restart the computer, let it boot normally, and let CHKDSK run.

We're glad to hear you solved your problem.
Thanks for the thanks.

If you run CHKDSK /R C: the same way it takes a lot longer to finish running than CHKDSK/ F C:, but it checks the entire C partition, even the free space, for bad sectors and if it finds any it "flags" them to prevent Windows from using them.

You could also run a hard drive diagnostics program.

Check your hard drive with the manufacturer's diagnostics.
See the latter part of response 1 in this:
http://www.computing.net/windows95/...

If you don't have a floppy drive, you can get a CD image diagnostic utility from most hard drive manufacturer's web sites, but obviously you would need to make a burned CD, preferably a CD-R for best compatibility, on another computer if you need to.

E.g.
Seagate's Seatools will test any brand of hard drive.
Do the long test.
http://www.seagate.com/ww/v/index.j...


The Windows version can be used if Windows works okay.

The bootable Dos versions of SeaTools can be used even if Windows is not working properly.

If the hard drive itself tests okay, any data problems found can be fixed, one way or another.
