Why does my laptop power button blink?
trevalen02 015 Years Ago One night I turned off my computer. The next day it wouldnt turn on. The power light comes on and blinks rapidly, now I cant get it to turn off or on. There is no boot up, no nothing. I real new to messing with computers so Ive been hesitant to open it up. But then I dont know what Im doing anyway. If anyone can help figure out this I would greatly appreciate it troubleshooting-hardware 1 Votes Up 0 Votes Down Recommended Answers
Squidly 015 Years Ago have you tried holding the power button in for about 10-15 seconds? this will usually kill the power to the board. Then power up and see how it goes from there. 1 Votes Up 0 Votes Down trevalen02 015 Years Ago Yeah, Ive tried holding in the power button, held it for 2 minutes and the light doesnt go out. There is nothing running on the computer, it just wont turn off and the light blinks very rapidly. It hasnt booted up either. No fans running, no nothing. I turned it on one day and all it did was start blinking. 1 Votes Up 0 Votes Down Squidly 015 Years Ago Have you tried pulling the power cord from the back of the system and plugging it back in? If so does it still do the same thing? 1 Votes Up 0 Votes Down trevalen02 015 Years Ago Yeah Ive pulled the plug and even turned off the switch where the power cord goes. Same thing happens, as soon as I plug it back in the light is still rapidly flashing and not doing anything else 1 Votes Up 0 Votes Down Squidly 015 Years Ago If you are plugged into a surge protector or UPS, try plugging it straight into the wall. If killing the power for a few minutes doesn't do the trick, it sounds like a hardware failure. Could be faulty power supply, or mainboard as the first possible culprit. I would suggest getting it looked at by a competent technician. 1 Votes Up 0 Votes Down ithelp 75715 Years Ago I think RAM is dead 1 Votes Up 0 Votes Down mitz 013 Years Ago If it is the ram shouldn't the fan inside be still running? I think it may be a power supply or the mother board. 1 Votes Up 0 Votes Down coolraj003 213 Years Ago I think its the power supply or the mobo thats gone, dont think there would be any issues with the RAM, dead ram would simply bring a blue error screen but other hardware would still function like the fans, drives etc. Lets just hope it is the PSU not the mobo for ya. Raj 0 Votes Up 0 Votes Down sittas87 9113 Years Ago Thats what Im thinking PSU or MOBO lets hope its your PSU for expense sake. try another PSU first in your machine you might just find the solution.if you can remember something suspicious that happend when it was working good/previous night you might just find an a hint to what might have caused it. 0 Votes Up 0 Votes Down freddyc 012 Years Ago I have one the same. y plug it in and just blinking. start fan for a few seconds. and start blink.

You should try to replace the psu, or try it in another pc, to be sure. :) 0 Votes Up 0 Votes Down Redzer 010 Years Ago I'm afraid if its not the PSU then there could have been a power surge from the adaptor that directly killed the mobo dc socket, expensive to replace. 0 Votes Up 0 Votes Down chrism88 09 Years Ago My computer is doing the same thing.....I had a breaker in the house to trip...The computer made a popping noise when I flipped the breaker back on...Now the power button on the front of the tower part is flashing orange and wont do anything....

hi, the popping noise isn't good for sure ,it may have toasted the motherboard,but that only a guess from a distance ,start by testing the power supply ,unplug power cord ,open tower and remove all addin cards and try turning it on,a fried network adapter or other card could stop it from booting . 0 Votes Up 0 Votes Down IPCxWhispererI 09 Years Ago I have the same problem with my computer and I am a certified tech. I have come to the conclusion that the motherboard if fried. The cause of the problem on mine was the power board came loose and shorted out on the metal casing suddenly. This caused the motherboard to catch a surge and fry.
