Hi i press the power button ,the fan run for 3 seconds then shut down again. the power supply blinking just once. nothing else happen. help me.


Could either be a faulty fan causing the pc to emergency shutdown to prevent damage, or faulty ROM/BIOS hardware. You will need to have a professional look at it to be absolutely sure.

When the computer on/off button is pressed , the CPU fan and tower exhaust fans start running, the blue light around the power button does not light and the boot up process goes no further. Fans continue...


A) When you hold a Power On button, (Switch actually), in for a count of 10 seconds, it turns the computer off.

(There is a Power On switch, located behind the plastic Power On button. Usually, the Power On switch snaps into the housing of the plastic Power On button.

Example of a typical ATX Power On switch,

http://www.directron.com/atxswitch.html

The Power On switch turns the Power Supply on.

Old computers had a metal rod, that when the Power On button was depressed, the button pushed against the metal rod, which in turn pressed against a power switch located inside the Power Supply.

The design after that, was a power switch located in the Front Panel. (Plastic front of the computer) A large cable, (Wire) ran from the switch to the Power Supply.

Now there is the Soft Power On feature. (PS_ON)

The Power On switch is a small Momentary Contact Switch. Pressing it closes a circuit. The Soft Power On circuit.

When a power supply is plugged into power, there is a constant 5 Volts (DC) present.
This is the 5 Volt Standby.

Closing the Soft Power On circuit, redirects the 5 Volt Standby power to a circuit within the Power Supply.
This in turn 'excites' the Power Supply, and turns the Power Supply on.

Sorry to be windy, but I wanted you to know how the Soft Power On feature works )

eMachines are a budget computer. As such they save the consumer money.
However in order to do this, the manufacturer will install low quality parts, in some areas of the computer.

One such part is the Power Supply.

1) ALL the LED lights combined use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts

3) A typical Processor can use 51 to 125 Watts.
Depends on what Processor it is.
(Had you stated the Model Number I could have told you)

Enough power to spin fans, but not enough to spin fans, AND turn the Processor on.

Do you have access to another computer that is unused, but has a Known to be good, Compatible power supply?
It could be used for a test unit.

Tell me the Series, and Model Number of your eMachines, and I'll tell you what Wattage it should have, and what power cables, for the Power Supply.

(Some examples of Series, and Model Numbers, T1090, E4264, W2925, and so on. The T, E, and W are a few examples of the Series letter.
The numbers following the Series letter, is the Model Number)

If you wish I can direct you in removing the Power Supply, and installing the test unit. (And/Or a new Power Supply)

Compaq nx5000 PC Notebook: my compaq nx5000 is notpowering up when i power it...


First check to ensure the battery is properly seated. If it's in good, then this is probably a power supply issue or a problem with the motherboard.

Compaq nx5000 with new battery and new power


Dear,

Try pressing the CAPS LOCK. If CAPS LOCK is responding then it is surely your inverter.

It is a known problem with the nx5000 series laptop.

The FAN switches off because Intel SpeedStep which is absolutely normal.

I faced and solved at least 6 - 7 such problems on different nx5000 laptops

If CAPS LOCK is not responding then its your motherboard.

Good Luck and Regards

As i put the battery in its place in the lab top, The fan start running without pressing the ON/OFF switch? lap top not working, only battery led flicking? what i should do?


make sure the laptop is fully powered off first by holding down the power button for about 5 seconds, then insert the battery and see if theres any change.
also try using just the power adapter without the battery and see if it starts.

Compaq nx5000 - will not power up. DIsk spins, green lights for a second , then powers down to only yellow light. SOmetimes - seems after long periods of no use - -powers up and runs. Have sourced new...


I just got my nx5000 up and running again. The memory needed to be reseated in the socket (got this tip of the HP site) All I did was open it up and reseat the ram - just took it out and put it back in again. Problem solved. I also took the opportunity to vacuum a little bit of dust out, but I don't think this was anything to do with the problem.

Get a copy of the service manual (Just google "hp service manual nx5000") it has easy instructions at how to get to the memory - it is just under the keyboard.

Hope this helps!

Problem with the power switch /motherboard


Remove the battery, plug it in and and try to turn it on. If it turns on without the battery, the most probable cause is battery worn out.
