Wont turn on


Mine doesn't turn on either.
I keep pressing the power button but nothing happens.

Press it longer than 3 second.
Press it harder than normal.
Also press the reset button at the back.

Nothing works it just won't turn on.

The power LED does turn on, but the heater and the rest of the display doesn't work.

There is no power from the battery or the adapter and the laptop does not recognise the adapter is plugged in. there are no lights coming on and the power button is doing nothing


Your battery maybe out of charge. Thats why nothing happens when you press the power button. The battery may not be charging because the power cord might not be working. Try another power cord.

Try removing the battery and plugging the power cord and switching on the computer. If its the problem with the power cord the computer wont start. If it starts, the power cord is working fine.

My G1 phone wont factory reset itself and i dont know what to do, im not sure if i can still return my phone and get a new one because i had it since March 13,2009


Have you tried a reset using the hardware buttons? To perform this, you need to turn off the phone first. While it is off, press and hold the home key and the power key at the same time. Keep holding the buttons until you see a screen with a triangle and an exclamation point in the middle. Once you see the triangle, let go of the buttons and open the keyboard. Press ALT+W at the same time, and the phone should reset.

you may have to turn off power at main box, and check wires at bottom of machine and any other junction box , from dishwasher to main power box. pull on wires to see if they will come apart.

Can you play back pictures and is the quality of these ok ? If you can but there is no image in capture mode then the CCD sensor is faulty and needs replacing.

My player won't turn on!!!


The m25 will not power on if LOCK/UNLOCK is in the locked position. If you press the POWER button, a padlock will appear on the LCD to remind you that the unit is locked. Confirm that the LOCK/UNLOCK switch is not in the locked position and press POWER to turn it on. If nothing happens after pressing the POWER button, the battery is probably discharged.
