On/off button for hp pc fails

On/off button for hp Pavilion PC fails to fully start the PC. The fans come on, but it appears the button is failing to fully power the whole pc -like the system board. The blue light in the button fails to stay on. Rarely, I can hit the button and the blue light stays on and everything seems to power up ok -but that was once in 30 start attempts.

I wonder if this switch (looks replaceable) is bad and can be replaced - has 6 wires from it to the system board?

New case fan running but still getting error message system fan failed.

Did you try;

Power off, power unplugged to computer.
Press the Power On button, and hold it in. Hold for a count of 10 seconds.
Let go.

Do this procedure two more times.

Plug the computer back into power. WAIT 1 minute, turn the computer on.

This method clears CMOS Error Codes, and sets BIOS Setup back to the factory default settings.

CPU fan spinning at required minimum RPM's?

Not talking about the SYS_FAN (Case fan)

Power supply unit starts (fan running) but computer does not....

Try swapping out the ram 1 at a time, making sure there is one memory piece there while testing. If no! check hard drive for activity.

Hi. I have a HP laptop pavilon dv 4t Entertainment pc. frequently its interactive log on process fail. Also it seems too slow to boot and I think in all processes it is slow working while its fan works...

the is overheating, ever get the lent cleaned out.
all CPUs run slower if overheated, all do, or halt. of too bad.
run it with no battery yet, see if all is ok, first.?
batteries are #1 failure point items.
no pc can run too long, and not pack full of lent.
why not just get the PC serviced by a tech, he knows all this magic.
cleans it, tests it, etc..

Hp pavilion a450n problem fan is running on high and keeps shutting down

First off - have you ever cleaned inside the case? You'd be very surprised how much dust often builds up inside a PC. After that it sounds like you might have another fan which has failed. PCs often have more than one inside and they also have temperature sensors to keep the CPU cool. If a case fan has failed it would not have air flowing inside to cool off the other components and then the CPU sensor would kick the processor fan into "overdrive". One thing to note; the difference between a two wire fan and a three wire fan is that the third wire is used to confirm the speed of the fan. Fans are usually easy to replace - just get the right size and the same right plug.

I have a presario R3000 notebook. just like to ask if the fan for ventilation underneath is working in a certain temperature. or it will automatimatically running when i plug in.. can some one help me....

There are several models of this notebook depending on the processor. Some only have one fan, otehrshave two. When operating the fan should start running. I have the higher spec R3000 and my fans start soon after the machine is turned on and sometimes throttle down if I have no activity. Upon starting to use it, they soon start again. Considerable hot air will come out the right back and side.

DO NOT block the air intake(s) on the bottom of the unit !!! You can burn up the processor.

System fan has failed

Your system's fan has failed. If it is under warranty, you need to have HP made aware of this failure.

Hp pavilion a305w isnt working

sounds like it is in standby mode..........try pressing and holding the power button until it turns off fully. then remove the power cable to reset the power supply, wait for 5 mins then plug in and try again,

it is also possible that you have a fault , possibly a failed power supply, it might be best to investigate that if the power reset doesn't work
