HP Pavilion a705w power supply

Power supply fan doesn't come on so i assume the power supply is bad. It would boot to Windows start up but never open windows. Think more could be damaged or would replacement power supply be good investment?

If you have a lot of time to fix your PSU and have a knowledge in soldering, you can unscrew it check for the burned electronics component inside and replace it exact value of d component. then check fan wire connection if it attached or still working.

Hp pavilion a705w - blue power light flashing, won't turn on


On the back of the power supply there is a 120/220 V AC selector switch.
It's possible that switch got knock on the wrong voltage position.


Pull the power cable. Move the switch back and forth between the two position.
Make sure you leave the switch in the correct selection. 120v = USA
If you have time,open the case and inspect the RAM module(s) and card(s). They can be un-sitted.
plug in power cord and power on the pc.

The computer isn't coming on the power cable is plugged in the green light is blinking but nothing else is happening


Do you hear fan starting noise? If you dont hear any noise most probably you need new power supply.
you can buy cheap power supply from www.aria.co.uk
if you hear the fan noise!
Does you motherboard starting with POST (a beep noise).
if you dont hear. well you need a new motherboard which should be compatible with your other peripherals.
if you hear a beep noise! Most probably your operating system is corrupted. (Boot file corrupted)
in this case you may have to install new operating system.

Thank you
if you got any problem let me know

I need to change my power supply in my HP Pavilion a705w, and the screws are on the back, the 4 main to the supply, but I'm on the other side of the power supply and I can't get in there to change it. How...


There should be at least 4 more larger screws, maybe even "thumb screws", that will have to be removed as well. These screws hold the sides of the case on. Try removing those and sliding the sides back to open up the case

Will not boot


You might have a bad or worn out hard drive. After so many reloads of windows the drive can have problems. Try a different hard drive. And reload windows.

Hp pavilion a705w. no peripheral response


The fact is *********** board is very likely the matter. See all devices that do not need the motherboard to respond are all working (cd/dvd tray opens and closes, fans are on etc). On the other hand all devices that need the motherboard to respond are not working (keyboard, optical mouse, etc). It is more or less conclusive.

I have a hp pavilion a705w bout 12-30-04 it wont boot most times


That's because it has a failing power supply. I post this a lot. Why? Because 70% or more of computer failure, is directly related to the power supply. Next up is Electrolytic Capacitor failure on the motherboard, (The 'Caps' that surround the processor, more specifically. These are Voltage Regulators for the processor)

Then harddrive failure.

Many times you'll see a solution posted to use a Restoration disk, or System Restore. This is just a 'Band-Aid' approach. The power supply, for you, is the problem.

I have a hp pavilion 513c it wont boot up! the


Hello,

There are only two ways this can go for you.

One- you need a new power supply

OR

Two, you need a new mother board

You can verify the power supply by checking it on another machine

If the power suppy is good

And you do not hear the bios beep- then you are looking at a new motherboard- I would double check the powersupply first- most stores that sell them will let you check before you buy a new powersupply.
