no power and green light on my hp pavilion is flashing

okay and if that doesn't work then what, because I've tried every suggestion and posts that I've read and still nothing. I moved the red bar back from 115 to 230 and back to 115 and nothing, I've put the hear dryer on the back of the power plug a couple of time for 30 to 60 seconds and still nothing, does it need to be on hot fool blast because I've been doing it on cool fool blast. the little green light on the back of the tower is still blinking and the power off light is'nt even on and when I turn on my monuter it says no dvi and vga signal, what does that mean? and could it be somthing bigger then useing a blow dryer to fix it?

Thx CH-iao it worked for me and its booting ok now although I have not unplugged the PSU cable from the wall. Do not want to risk it because the customer has brought it in for data transfer. Once again thk you for your advice and now becomes part of my technical experience....BTW the hair dryer advice...it did not work for me

 

Cheers!

Thanks paulmar, I've also had to do the same procedure everytime the electicians come. I always forget to turn off this old HP Presario SR1103WM that I use as an ever-running server and end up with the green LED light flashing on the power switch. Anyway, as you said,

 

unplug the PS power cord,

unplug the Motherboard (MoBo) main connector,

reconnect the PS power cord,

hold down the power switch on the front of the desktop,

CAREFULLY (I know, scary),

reconnect the MoBo main connector while still holding the main power switch down.

 

btw. Wear some thin latex gloves if it makes you feel better.

 

What I can add to your comment is only that sometimes it takes SEVERAL times (10?) before the PC kicks in and the power really starts, so just keep keep plugging and unplugging that MoBo main power plug several times while holding the front PC switch until you hear the fans start to go. Of course there's always a possiblity that you really do have a bad PS, especially if it's over 8 years old or so in my experience. Good luck everyone.

 

CH-iao

I used a hybrid of the answers given here and it worked. I used Erico's idea, basically, but also incorporated unplugging the motherboard. Here's the steps I followed:

 

1. Unplug plug from wall outlet.

2. Unplug plug from back of computer tower (PSU).

3. Open computer and unplug main power connector to motherboard.

4. Switch voltage from existing setting (115) to opposite setting (220) and back again. I did this a few  times, "just to be sure"...

5. Return plug to wall socket.

6. Return plug to back of tower (PSU). (At this point, the  formerly flashing green light was  now showing as solid ).

7. CAREFULLY reconnect power cable to motherboard making sure to keep fingers clear of fans, etcetera.

8. Press computer power button on front of unit...

Presto... worked like a charm! If all else on this page fails, you may want to try this method. It worked for me.

You need to folow the steps exactly.

IMHO, I would try a new PSU,  as your old 250W is marginal. Dimensions: 140L x 150W x 86H mm (5.5" x 5.9" x 3.4")
Efficiency: 68% minimum at full load. When you pull it out, it probably states 200W on the 12v rail.

You can do better with a 80+ efficiency PSU in the 350-430W range.

http://www.newegg.com/Product/Product.aspx?Item=N82E16817182202

This one will give you 396W on the 12v rail.

Question about the blow dryer trick:

Do I unplug the motherboard before blowing in to the psu?

About my HP Pavilion a610e quandary:

Do I leave the motherboard and psu plugged in during the blow dryer trick? Do I follow-up with unplugging and re-plugging the motherboard? Should I switch the psu setting too?

I tried everything and everything worked in the past. Unplugging power & motherboard, then re-plugging motherboard stopped working.

blow dryer trick only worked in combo with unplugging motherboard afterwards.

Removed psu and it works.

Replaced cmos battery in the past. It made no difference.

I unplugged the psu and switched the power selector, then plugged in both ends of the power cord again. But this didn't do it.

I read the old comments and one says leave it plugged in during the blow dryer trick. However I tried it unplugged, then it worked when followed bi unplugging the motherboard a few times. But, not this time.

I know it will eventually turn green but my fingers hurt from unplugging the motherboard after the blow drying.

specifically, do I leave the motherboard plugged in during blow dryer, and do I also leave the power plugged in?
