That question does not reference what exactly is going on. Please step through from plugging in power adapter to power from wall outlet and pressing the power button.

ie: 1) plug in power adapter (i see charging light)
2) pressing power (i see boot screen logo)
3) next screen (i see windows boot logo)
.... and so on...

After connecting the AC adapter to a wall outlet and to the computer press the power button the right side of the inspiron. The button itself should then lite up white if the power adapter is good. If not, check the power outlet you are using. Plug in something else and see if it works on this wall outlet. Some outlets are connected to a wall switch. If its still a nogo you may need to replace the AC adapter.

Please check if the power cord is connected properly in the wall outlet and in the TV. Check the wall outlet. Has it got power? Check if there is red light when the power is switched on at the wall outlet. If there is red light then press the power button. Does the TV turn on? If not then your power button is defective and requires replacement as it is not making contact. Also please try to start your TV WITH THE REMOTE CONTROL. At times it helps.

If this doesn't work, you can reset your device. To do this, press and hold the Power button for fifteen seconds. Release the Power button when device begins to restart.

plug your pc directly to your wall outlet and see if it turns on. If it works, then the problem is your power supply. If power supply has a reset button, press it and try again. If pc does not turn on when plugged to wall outlet, then power supply for pc may be out.

After posting my problem, I did some more browsing and came across this on the amazon webiste:

31 of 32 people found the following review helpful: Cure for not able turn on the Go 510, 16 Jun 2007 By Sirius (Essex) - See all my reviewsI like the tomtom so far the only niggle was it would not turn on once.
No troubleshooting on instructions, found cure on internet,reset button
underside. With the tomtom turned over and the card slot on top right hand
side there is a small rubber foot at the half moon shaped enterance, up at about the 10 o'clock position from the foot,but before the green circuit
board there is a small half round cut out with a hole under you need to press in this hole for a few seconds with a paper clip to reset. I wonder how many people have sent their tomtoms back that would not turn on.

Tried it & worked a treat!!! Newcastle here we come again ...

1. Connect the TomTom to the USB for power (green light should be on).
2. Hit the reset button on the bottom of the device - you should feel it depress slightly.
3. Press firmly and hold the power button and count to 10.
5. Try this a couple of times if it doesn't work the first time.

Even if your battery is ****, the power connection has a pass-through, so you can still use the device as long as its connected to the charger.

I had this problem. had it plugged in charging and then pressed the the reset and the power button at the same time for about 30-50 seconds and then after that pressed the power button and so far so good
