It is possible that your hard drive has crashed
the power button
with the power button..... Press it
Like any other computer, Dell's have a power button. Just press it and the computer starts to boot. The button usually has a light in it to see clearly when it is on.
On a desktop, the power button will usually light up. On a laptop, the power lights (located on the front of the laptop) will usually light up first.
This ring is probably the Hard Disk light surrounding the power button. This will illuminate and flash whenever the hard disk is "thinking" or reading data.
In most cases your HP notebook is in "power saving" mode. Please make sure your notebook is plugged into a power source as the battery could the result of the "blinking" ON button. If the battery is low, the computer will not turn on and will stay in "sleep" mode. If this is not the case, simply press and hold your power button that is blinking for 5-10 seconds. You will see your computer turn-off. Press the power button again (*given that the steps above have been followed through) and your computer light should turn back on and remain solid. If for some reason you find that the "ON" button light is constantly blinking, but the HP notebook is not turning on, make sure that your battery is not dead, and your power supply (the actual power cable and black power bar) is working.
normally the power button :)
On the left side of the console is a button labeled power. When this button is pushed a power light comes on in dash. This button is used when you need more power such as climbing a steep grade.
push the power button! :P
umm... the power button?
turning on the computer, starting the computer, startup, or booting up the computer
Press the "power off" button on your computer. This button apparently has access to all of the multiverse of power, and will work, unless your computer is VERY screwed up.
