Normally with external displays the easiest way to do it is make sure the laptop is connected to the internet. Then turn off the laptop..now turn on the TV and connect the hdmi cable to the TV. Now switch the TV input to hdmi. With the laptop still turned off connect the hdmi cable to the laptop. Now you have everything connected, turn on the laptop and the laptop should find the TV and download any drivers it needs. And that should be everything you need to do.
Turn laptop off, unplug power and battery, use a screw driver to get back plate off. Then unplug the CMOS battery. Put battery back in, turn laptop on. Turn laptop off. Plug cmos battery back in. Put battery back in and when you turn laptop back on again password should have reset :)
Did you have exhausted the battery power? If so, maybe the laptop can't turn on as soon as you plug in the ac adapter, as you can try to let the laptop charged for a time and then turn on the laptop to see if every thing is well.

Let's try to determine where the problem is. Since you didn't mention the Brand, model or operating system, I'll try to wing it. Turn everything off. Take out your battery. Turn the system on without the battery in place. Does it turn on? Yes means the battery is bad. No means either the laptop or charger are bad. Go to Best Buy and purchase one of their laptop chargers (must be for your brand). Now try to turn on laptop without battery in it and with a new charger. Does it turn on? No means there's a problem with the laptop. Yes means your old charger was the culprit. If no put in the battery and wait a couple of hours. There are some laptops that still use an old circuitry that the battery must be in for the unit to turn on.
its in the "performance information and tools" file in the control panel. when i click "rate this computer" link, my laptop will turn off automatically. after that, when i turn it on again, it seem like my laptop becoming unstable. it will turn off anytime it want.
