WAS RUNNING ON BATTERY, HAD 5 MINUTES LEFT PLUGGED IN ADAPTER, NO ICON SHOWING IT GETTING JUICE. TRIED TO SHUT DOWN, BUT, RAN OUT OF BATTERY BEFORE SHUT DOWN COMPLETE.....NOW NO LIGHTS NO MOVEMENT, NOTHING...THOUGHTS?

is the battery showing fully charged ?. If it is remove the battery for a few minutes then replace it this will reset it without any data loss .

take out the battery and unpluge to cord from wall. put battery back in, then pluge it to wall outlet. turn computer on.

I usually try to hold the power button for >5 seconds to reset it. No lights even when plugged in?

If your iPhone's battery runs very far down, the iPhone won't turn on. That's because it's using its remaining battery life to preserve your data and settings.So, your iPhone could be refusing to turn on because its battery doesn't have enough juice. In that case, plug your iPhone into a wall charger or into your computer (plug it directly into the computer; some USB ports on keyboards don't have enough power to charge iPhones). Let it sit for 10-20 minutes. If it was low on battery and needed a charge, when it's got enough juice to power the screen, it will turn on and show you its charging status, starting with the red battery icon.During this process, you may also want to make sure there's no lint packed into your cable or the iPhone's dock connector. This isn't a hugely common problem, but a lot of pocket lint could interfere with the iPhone getting a charge.

not turning on. red notification light showing

The reason why your password is still re-curring after removing the CMOS battery is because when you were doing so, some of the cables supplying power to the Board were still plugged.
So before using the CMOS removing method, first make sure that you have disconnected ALL source of power supply cable from the Board, then remove the CMOS Battery for a few seconds, and re-insert it. It should work like that.

Try removing the battery and see if will start up with power adapter. The battery may have failed. If it is a couple years old the battery may need replaced.

While the unit is connected to the PC, hold down the RESET hole at the back for 10 seconds.

The Charger could be bad, Try replacing that, or let charge, then try to turn on. The laptop might not boot with AC power. kinda stupid but maybe. If that doesn't work, the AC adapter is bad.

Dumb question, is it plugged in? Can you verify the lappy is getting DC juice from the power adapter?

If electricity is available from the charger, when plugged into the lappy can you see a charging icon either on the battery or some sort of display near a on, wireless, power, battery display? If no symbol shows charging, you either have a bad jack in the lappy or a bad battery.

If DC is not available from the charger, then it's bad.

Hope that helps;)
