It sounds like you have some serious wiring issues within the building / house you are in, and voltage is being sent back through ground when the printers fuser goes into warm-up.

A line conditioner / stabilizer may help, but honestly, I would call an electrician before it completely shorts out the computer, or burns the house down.

Cant get power saving mode off


Step 1:
Sleep Mode b> Sleep mode is primarily used with home computers (desktop computers). Sleep mode is designed to save the current work, programs, and settings of your computer using your computers memory, while using very little power. b> Hibernate Mode b> Hibernate mode is primarily used with laptop's. Hibernate mode is designed to save your computers current state on to the hard disk, then turn off your computer to stop using power completely. This mode is usually used when you do not plan on using your laptop for an extended amount of time. Benefits b> Using Hibernate mode is more power-efficient, but files may become fragmented over time by using this mode frequently. Sleep mode does consume more power, but the advantage that Sleep mode has over Hibernate is that it does not take as long to resume your computers former state when you are ready to continue using it.

I am unable to access the internet from sleep mode Can only get on internet from shut down mode


Three possible causes of sleep mode. first, an extensive screensaver with password lock prevents display. A condition that is observable as a blankscreen also known as sleep mode. Second, a computer power saver settings that shutsdown during idleness. Third, An improper shut down of the computer would have caused a sleep mode to save the system data files.



Restoring the computer to regular functionalioty

First solving predictable sleep mode settings
1. A movement of mouse pointer across the screen should reestablish unprotected password modes
a. password protected sleep mode would display an promp message requiring key code soon after the mouse pointer has changed direction

sloving unpredictable sleep mode settings
1.A computer power saver, screen saver, or splash screen displays prevnting programs acess would require manually powering off the computer system.
a. A manual power back on of the system should restore to program functionality mode

important notes
1. contact expert technical assistance

Monitor works fine until the sleep mode and then it goes blank. I have to unplug the power button and it does work again


It seems it is a motherboard battery problem. It most likely is not the monitor which is in "sleep mode", it is the computer itself.

When you cannot get a computer out of "sleep mode" by any other means, typically the cause is that the button-cell-type battery of your computer, which is located on the motherboard, is empty. When your computer detects this battery is empty, it goes into a low-power mode. The solution is to replace the button-cell battery on the motherboard of your computer

Computer will not go into sleep mode


External drives (hard drive, DVD burner, iPod, USB drive), printer, a worn out mouse button, debris in/on the keyboard, and cats are all things that can cause your computer to refuse to sleep (or wake it shortly thereafter).  Rule out these first.  I have had the same problem in the past.  It is almost always one of these that causes the problem.

Won't turn on


More than likely the power supply has defective parts, and or some other modules have failed.

Using a generator to direcly run a Plasma or LCD screen, and most any high end equipment is very dangerous for these. They are very critical to the quality of the electric power feeding them. If the AC frequency goes too far off specs, or there are noise spikes or distortions in the sinewave structure of the AC power, this can cause damage.

If you have a very high quality generator with very good power conditioning, frequency stabilization, and voltage regulation this would be the proper way to go.
