Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.


Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.


You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.


If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.


If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

When the screen is white instead of taking out the battery and putting it back in can I do something else?


Not sure why your removing the battery?
If you are shuting down the machine. Close all running programs before shuting down otherwise the machine has to close each program in turn before thr machine can shut down all together. Depending on how the settings are for the power button. The shut down process can be forced by holding down the power button until the machine has shut down. Black screen instead of white. Hope this helps answer your question.

My Nextbook shut down and won't come back on


If the temperature is hot in your place then the PC Laptop may shut down due to overheated system.The machine automatically shuts down to prevent any internal damage. However in some cases you can prevent the shut down if you can control the speed of the CPU fan which can be done by the following software called "Speed Fan 4.42".
Download it from here.

If the weather is not hot around you and the system still shuts down then at least cleaning service is required from a good repair shop or a tech. There must be a lot of dust and the ventilation system might be choking with dust and unwanted atmospheric objects so proper air flow can be maintained in the machine.

Good Luck!

I just opened my laptop to use it and it is froze up on me and will not shut off


to shut down press and hold the start button until the machine shuts down, can take up to 10 seconds for the machine to shut down. If this does not work remove the power lead and drop the battery out of the system. You access the battery from underneath - there will be a slider you need to push to eject the battery.

E-machine computer will not shut down


When you say "it will not shut down", are you referring to clicking on start and then shut down?

You could try forcing a shut down by holding the power switch down for about 5 seconds.
