Why is my device not turning on?
When I press and hold the power button, my device will not turn on.
The possible hardware causes are :
-Bad power on/off button
-Bad motherboard (some blown or non working component or part)
-Bad psu or battery (probably not if you tried powering on with and without AC adaptor)
-Bad battery (there are devices that canot work without battery, even if they are connected to AC)
Hope this can help a bit!
First, make sure your tablet is charged. If the device does not charge, try another charger. If this fails, the issue may be with the battery or the logic board. Try replacing the battery. If that does not work, you will have to replace the logic board. See HP 7 1800 troubleshooting for more information.
