VAIO laptop locked and won't boot

After connecting my Sony VAIO AR520E VistaHP system to the Internet
using my Cricket wireless dongle, as I have done many times before,
when I returned to the laptop I saw a login-like screen that stated
"Computer Locked" but when I moved my mouse to unlock it the screen
went black and I have not been able to get the laptop to reboot since
then. Not even the VAIO logo screen displays.

I disconnected it from the mains to run it off the battery but that
made no difference. The power light remains on but the battery light
comes on briefly then turns off. The hard drive light doesn't show
booting activity. When I plug it into the mains the AC adapter light
stays on but otherwise it behaves the same as the battery power.

Any help troubleshooting this issue will be greatly appreciated.
Thanks.

Boy that sounds serious! Probably wouldn't hurt to connect it up to an
external monitor. Although I don't think it will do anything really.

Sounds like some sort of hardware failure so far. Does the computer beep
at all? If so, you need too look up what those beep codes means.

The next step is what I would do is to remove devices. Anything plugged
into the computer (keep the power cable plugged in to try to turn on).
Then try and remove the hard drive and CD/DVD drive. Then see if the
computer fires up. If not, remove the memory and try. And maybe
disconnecting the keyboard and pointing device and then trying.

If all of this fails, sounds like a motherboard failure. Some CPUs are
socketed and so if you have a spare you could try that. Or the BIOS
could have failed. Reflashing the BIOS may work to get everything going
once again. Otherwise if it isn't working up to this point, sounds like
it needs a motherboard replacement. Which may not be worth it because it
is usually expensive.

Oh here is something you should try first! Remove the AC and the battery
and press and hold the power button down for about 10 seconds. Now
install the battery and the AC and give it a try.

Thanks for your reply. When I turned the laptop on this morning it
booted into Vista just fine after I selected the "Start normally"
option. I can only guess the problem had something to do with an
intermittent power issue.

No, mind closed.

Wow! An idiot on the lose. Please fill out an application form at reception
as we in comp.sys.laptops already have a village idiot. We'll inform you
when the current guy dies.
