Question about PC Desktops
I shut off the tower and unplugged it before it shut down.
the monitor says override and the tower won't turn on.
a green light in the back of the system unit flashes but no fans run and no power lights come on in front.
I had this problem and i tried everything to make it work. Now all i do is put a hairdryer at the back whilst the computer is plugged in until the light stops flashing then switch on as normal. I also noticed that when the air is warm i do not have to use the hairdryer hopes this helps.

We had a power outage and afterwards our Sony Vaio would not power on and had a blinking green light. We found the suggestion to try the hairdryer and Wow we tried the hairdryer on the blinking green light and it worked......we were ready to trash the tower and get a new computer. Thanks so much for this advice. You saved us a lot of money and headaches!!!!

I don't know why using a hair dryer on the back works, but, it works like a charm. Need to keep it aimed at the blinking green LED for 2-3 minutes. LED stops blinking....computer powered right up. Damnedest thing that I've ever seen!

I opened up my pc to clean it out and I got the blinking green light when I put it back together. I thought the blowdryer idea was a joke...but sure enough it worked. Who the heck thought of that?!?! Thanks for saving my ****!

The hair dryer work because it is a dry solder in the PSU, heat makes it expand and connection is made!

I had unplugged the Sony for about 24 hours and it was a very cold night. I don't know why heating the back of the unit makes the green light come on but it did!

I read all these posts and thought this was a well played out joke and to prove it, I tried the hair dryer suggestion- sure enough 3 minutes later, the computer came back to life. I guess the heat improves the electrical qualities somewhere in the circuitry just enough to get the system to work. I also think whatever it is that needs help from the dryer, may be on it's way out so I decided to back everyting up on an external drive just to be sure. It is working for now- once I jump start it with the dryer.

I had turned off the power strip to my computer last night...just trying to reduce energy use after reading about home energy waste with little built-in lights. This morning, I had the "flashing green light" problem when I turned things back on... and tried the dryer method. It worked! Does anyone know why this happens?
Thank you so much for this tip.

Does this work if the green light is steady and computer won't turn on? My light isn't flashing

Wonderful ! As an electronic engineer and IBM/Lenovo specialist, I'm used with laptop repair. I changed all suspicious capacitor in vain, checked all MOSFET component, no help. And fortunately i came cross this post dealing with a VAIO VPC EB1M1E laptop. I took off the optical drive and sent hairdryer hot air on flashing green light part. After a while the green light became steady. Too long heating make it go blinking again. Back with green light steady again, I close the lid, the fan began to run for normal shutdown. I opened it again and boot the laptop: Welcome back to life. Great thanks for the genious who discovered this amazing trick, but no more Vaio, next time.

Thought I had to buy a replacement power supply or a new PC.... Thank you so much guys, after reading the "dryer solution" at past midnight in bed, I got out and went down stair w/ the dryer. Yes, it took ~3 minutes (lo speed hi heat) aiming ~ 2" at the blinking blue light below the AC plug, plugged in, the light stopped blinking, stayed on. I was so excited and turned on the PC. Yes, IT WORKS....
thank you, thank you, and thank you.

OMFG u guys! Reading these posts I thought impossible! Well I didn't have a hair dryer so I tried the next best thing! After trying everything I knew possible only to have the same issue, I read the posts and broke out the heater. It took a little while but I'll be damned if it didn't work! Bravo to the genius who came up with this remedy........using an household item! TYSM
