1) The on-off switch may be going bad.
2) There may be a cold solder connection breaking loose where the power cable attaches to the circuit board.
3. The plug part of the power cable could be faulty. The wires intermittently separate from the connection in the plug.
Please go through the following checklist:- Make sure the power cord is plugged in securely and directly to the power outlet. Power surge protectors can draw power away from the printer.- Disconnect the power cord from the power outlet and the back of the printer and then reconnect it.- Check the power supply box (if there is one) to see if it is warm or cold, as there could be a defective power supply issue.- If there is access to a voltmeter, test the power supply to ensure that it registering the correct amount of voltage (most Lexmark printers have a 30Volt output).- Make sure the correct power supply is connected to the printer.

Hi erin mckinle,
That is probably it's, uh, analog power saving mode. When the screen goes black and the power button flashes, make some mouse gestures or hit some keys that would not affect anything (try spacebar). That should bring up the screen. If you think it goes into power saving mode too fast, go to Control Panel --> Power Options, and change the values. Hope this helps.
Yes, this is common, if the power cord at the connector is flexed continually then the metal fibres in the cord will break due to metal fatigue.
You can cut off the connector away from the break and fit a new connector on the cord, make sure the the wires are soldered correctly to provide the correct polarity at the connector.
The problem could be at the laptop where the connector plugs into the laptop's power socket. It could have a dry solder joint or the socket is faulty. This requires dismantling to repair.
The HP warranty would cover the normal warranty period and would not extended for worn parts.
If your dryer is not getting power there are some things that can cause this problem,
No house power supply going to the dryer,it could be a tripped breaker or blown fuse depending on which kind of electrical panel you have.
A bad or defective door switch, if the door switch does'nt work the dryer will not run.
The power cord connected to the dryer could have a Broken or burned connection at the dryers teriminal block.
If the thermal fuse is blown the dryer will not dry or it may not work at all.
If the timer is bad you might have to call a appliance repair man.
