Power to unit but will not turn on

Check electrical power with a multimeter, if electricity is present then very probable that the control board located within the door has failed.

Lost power adapter for Hitachi Deskstar HDP725050GLA360 Exteranl Harddrive How do you recover the data without electricity?

if the hard disk has crashed and the sound when it runs later he failed to be detected by the system, it is difficult to restore the data in it because it was not detected by the computer. The cheapest way is that you replace with only secondhand.

We were without electricity for 2 daya following hurricane Irene. When power was restored, the oven display (time, temp, etc) did not come back on. The oven lights come on when the button is depressed. and...

Try turning off the circuit breaker to the oven for 30 min or so and then turn it back on. If it does not come back on the oven probably got a power surge and the control has been damaged. Hope that helps

Have kenmore 61951 dryer PF comes on go thru the steps it turns on and then shuts off what could be the problem

PF is a power failure error meaning electricity has been interrupted to the machine. Any electrical interruption to the machine such as a circuit breaker being reset or weather related power outage can cause a PF error code. Try resetting the appliance by disconnecting it from the outlet or switching off the circuit breaker for 20-30 minutes, then restore the power. If the reset doesn't work I suspect the control board has failed.

The electricity went off and when it came again the my dell optiplex 360 failed to startup. Since that time when I press the power button it turns yellow and failed to startup.

Unplug the power cord for about 30 minutes, plug back in (obviously :-) then try it again. No guarantees but this fix has worked for a few of my clients.

Not heating inside the home

Turn your fan switch at the thermostat to on, if the blower starts that is
better news for you. If it does not start you will need to check the fuses
or breakers.

If you are electricity driven. Turn power off, remove blower door compartment, remove and label thermostat wires. Hook a jumper wire
between R and W. Put door back on, restore power, if furnace starts and heats your problem is probably the thermostat

My gateway desktop PRB 510S, if I turn it off and unplug it or electricity goes off, the computer wont start back again. Wont do anything. No lights no fan, nothing. Then 5 to 10 minutes after I turn it on...

Try connecting a different power supply to it. If the same situation repeats, then it's an internal (motherboard) problem. If the problems go away, then the power supply needs to be replaced.

6 years... I'm surprised the PSU even lasted that long! The power supply is the cheapest part of the PC and usually one of the first parts to fail. Don't worry, a replacement power supply is not too expensive. Good luck!

Power outage,monitor wont power up,hope its not fried

I may or may not make your day. (But I wish you to know that I want to! lol!)

I believe it's not your monitor, I believe it's your computer. (Oh, that helped, huh!) However, don't freak out yet, it maybe a simple fix.

Let's test my theory. (I'm a computer tech with over 20 years of experience)
1.Do you have another monitor available for a test? Plug it into your computer, see if it comes on.
No can do? How about taking your monitor over to a friends, or relatives house, and see if they will let you plug it into their computer for a test. Even if your monitor should be bad, it absolutely won't hurt their computer.

2.Your monitor checks out okay on someone else's computer?
Or, another known, good, monitor, doesn't work on your computer?
Your power supply isn't any good on your computer.

The power outage is also referred to as a 'Brownout'. Too much electricity was needed, and the power utility service couldn't handle the load, or a transformer down the line, blew.

This causes a voltage spike. The first hardware component in a computer that is affected, is the power supply.

Your computer may seem like it's coming on. Lights light, fans spin, and it sounds like the harddrive is whirring away!

Not so! Inside your computer power supply are Electrolytic Capacitors. These are used as Filters. They filter the incoming AC electricity, and filter the outgoing DC electricity.
These capacitors are the weakest link of a power supply. (Next is the Rectifier bridge, then the transformer. IF this SMPS power supply uses a transformer)

When these capacitors start to fail, they are weak. For simplicities sake, let's just say they are small aluminum 'cans', and have Electrolytic paste inside. When the capacitor starts to fail, the Electrolytic paste develops a gas inside. (Hydrogen gas) This gas expands, and pushes on a seal inside the capacitor 'can'. When the seal is broken, Electrolytic paste starts to ooze out. So much paste loss, and the capacitor operates in a weakened state. Too much paste loss, and the capacitor fails.

The capacitors used in the output stage of the power supply, filter DC electricity. They convert 'raw' DC electricity, into 'true' DC electricity.

Inside your computer is a processor. This hardware component must have a steady, true, clean, supply of DC electricity, ot it won't turn on. (Sometimes it may turn on for a few seconds, but will turn right back off)

ALL the lights for your computer use less than 1 Watt of DC electricity.
EACH fan uses 2 to 3 Watts. The harddrive spinning uses less than 5 Watts.
A typical processor uses 55 to 125 Watts!
Your power supply has enough power for everything else, but when it comes time to turn on the processor, it 'falls on it's knees'.

No processor, No computer. No computer running, the monitor doesn't get a signal, and stays in the power saver mode.
(No processor running, also means the harddrive isn't activated to find the Boot Sector. It just sits there and spins the platters inside)

Solution? Buy a decent, affordable power supply, and replace the one you have.
Your Gateway tower probably has a 305 Watt power supply.
It's an ATX style of power supply. The type used in about 90 percent of computers. These are Cheap, and easily replaced.
Examples: (I suggest the Ultra brand. It also has a lifetime warranty)

To replace:

Before you do, however, there is one more thing I would like you to check, first. Check the Electrolytic Capacitors on the motherboard.
Specifically the ones that surround the processor. These 'Caps' are Voltage Regulators for the processor. IF even ONE is bad, the processor won't work.
This link takes you to a website, that shows you photos of visual signs of failure, with the capacitors on the motherboard,

FIRST, computer unplugged from power, computer case open. Touch the metal frame of the computer case, to relieve your body of static electricity.
